Abstract
Provided herein are reactive aromatic molecules (e.g., substituted chrysene heterodimers) encodable as base-four sequences for the design and integrated synthesis of nucleic acids (e.g., DNA, RNA, hybrid DNA/RNA) and associated phospholipid bilayers (e.g., cellular membranes). For example, 3,6,9,12-tetrasubstituted chrysene is coupled with 6,12-disubstituted chrysene through -electron stacking to form a base-four heterodimer. The orientation of the ring structure of the tetrasubstituted chrysene in this heterodimer comprises a base-two (binary) structure and the relative alignment of the ring structure of the disubstituted chrysene to the tetrasubstituted chrysene comprises a second independent base-two (binary) structure. This collectively results in a base-four (quaternary) complex composed of four independent reaction environments. Methods of using and forming these molecules and systems associated therewith are also described.

Examples of hydrocarbon radicals include, without limitation, alkyl, alkenyl, alkynyl, aryl, aryl-alkyl, alkyl-aryl, and any combination thereof (e.g., alkyl-aryl-alkyl, etc.). As used herein, unless otherwise indicated, hydrocarbons may be monovalent or multivalent (e.g., divalent, trivalent) hydrocarbon radicals. A radical of the form-(CH.sub.2).sub.n, including a methylene radical, i.e., CH.sub.2, is regarded as an alkyl radical if it does not have unsaturated bonds between carbon atoms. Unless otherwise specified, all hydrocarbon radicals (including substituted and unsubstituted alkyl, alkenyl, alkynyl, aryl, aryl-alkyl, alkyl-aryl, etc.) may have from 1-45 carbon atoms (e.g., C.sub.1-C.sub.30, C.sub.1-C.sub.20, C.sub.1-C.sub.10, C.sub.5-C.sub.15, C.sub.5-C.sub.30, C.sub.5-C.sub.40, C.sub.10-C.sub.40, C.sub.1, C.sub.2, C.sub.3, C.sub.4, C.sub.5, C.sub.6, C.sub.7, C.sub.8, C.sub.9, C.sub.10, C.sub.11, C.sub.12, C.sub.13, C.sub.14, C.sub.15, C.sub.16, C.sub.17, C.sub.18, C.sub.19, C.sub.20, C.sub.21, C.sub.22, C.sub.23, C.sub.24, C.sub.25, C.sub.26, C.sub.27, C.sub.28, C.sub.29, C.sub.30, C.sub.31, C.sub.32, C.sub.33, C.sub.34, C.sub.35, C.sub.36, C.sub.37, C.sub.38, C.sub.39, C.sub.40, C.sub.41, C.sub.42, C.sub.43, C.sub.44, C.sub.45). In certain embodiments, hydrocarbons will have from 5-35 or from 1-20 or from 1-12 or from 1-8 or from 1-6 or from 1-3 carbon atoms, including for example, embodiments having one, two, three, four, five, six, seven, eight, nine, or ten carbon atoms. For example, hydrocarbons may have from 2 to 70 atoms or from 4 to 60 atoms or from 4 to 20 atoms.
(33) Typically, alkyl groups described herein refer to a branched or straight-chain monovalent saturated aliphatic hydrocarbon radical of 1-30 carbon atoms (e.g., 1-16 carbon atoms, 6-20 carbon atoms, 8-16 carbon atoms, or 4-18 carbon atoms, 4-12 carbon atoms). In some embodiments, any hydrocarbon of the present disclosure may be an unsaturated alkyl (e.g., alkenyl, alkynyl). In some embodiments, the alkyl or unsaturated alkyl group may be substituted with 1, 2, 3, or 4 substituent groups as defined herein. Alkyl or unsaturated alkyl groups may have from 1-26 carbon atoms. In other embodiments, alkyl or unsaturated alkyl groups will have from 6-18 or from 1-8 or from 1-6 or from 1-4 or from 1-3 carbon atoms, including for example, embodiments having one, two, three, four, five, six, seven, eight, nine, or ten carbon atoms. Examples of alkyl groups include methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl, undecyl, and dodecyl groups, and unsaturated versions of these groups are considered within the scope of the disclosure. Heteroalkyl groups may refer to branched or straight-chain monovalent saturated aliphatic hydrocarbon radicals with one or more heteroatoms (e.g., N, O, S, etc.) in the carbon chain. In some embodiments, any hydrocarbon of the present disclosure may be an unsaturated heteroalkyl (e.g., heteroalkenyl, heteroalkynyl). Heteroalkyl or unsaturated hetoralkyl groups may have 1-30 carbon atoms (e.g., 1-16 carbon atoms, 6-20 carbon atoms, 8-16 carbon atoms, or 4-18 carbon atoms, 4-12 carbon atoms) with one or more heteroatoms replacing the carbon atom in the carbon chain. In some embodiments, the heteroalkyl group may be substituted with 1, 2, 3, or 4 substituent groups as defined herein. Heteroalkyl or unsaturated hetoralkyl groups may have from 1-26 carbon atoms. In other embodiments, heteroalkyl groups will have from 6-18 or from 1-8 or from 1-6 or from 1-4 or from 1-3 carbon atoms, including for example, embodiments having one, two, three, four, five, six, seven, eight, nine, or ten carbon atoms. In some embodiments, the heteroalkyl group can be substituted with 1, 2, 3, or 4 substituent groups as described herein. Examples of heteroalkyl groups are an alkoxy. Alkoxy substituent groups or alkoxy-containing substituent groups may be substituted by, for example, one or more alkyl groups. Cycloalkyl or heterocycloalkyl groups described herein typically to saturated cyclic alkyl or cyclic heteroalkyl groups having at least one ring structure such as being monocyclic or polycyclic (e.g., bicyclic, polycyclic). Cyclo groups may be unsaturated such as cycloalkenyl or heterocycloalkenyl. Cycloalkyl groups or unsaturated cycloalkyl groups may be optionally saturated and be, for example C.sub.3-C.sub.15, (e.g., C.sub.3-C.sub.12, C.sub.3-C.sub.10, C.sub.3-C.sub.8, C.sub.4-C.sub.7, C.sub.3-C.sub.4, C.sub.5-C.sub.6). Heterocycloalkyl or unsaturated hetercycloalkyl groups may be, for example, rings being 3 to 15-membered (e.g., 3-12 membered, 3-10 membered, 3-8 membered, 4-7 membered, 3-4 membered, 5-6 membered). In various implementations the cycloalkyl or heterocycloalkyl groups may be optionally substituted with a substituent as described herein. For these groups may be 1, 2, 3, or 4 substituent groups as described herein. Acyl groups are generally groups conjugated via a carbonyl group. For example, acyl groups of the present disclosure may have the structure-C(O)R, wherein R is hydrogen or substituted or unsubstituted alkyl (e.g., C.sub.1-25 alkyl, C.sub.1-15 alkyl, C.sub.1-8 alkyl, C.sub.1-4 alkyl).
(34) Aryl groups may be aromatic mono- or polycyclic (e.g., bicyclic) radicals of 6 to 12 carbon atoms having at least one aromatic ring. Examples of such groups include, but are not limited to, phenyl, naphthyl, 1,2,3,4-tetrahydronaphthalyl, 1,2-dihydronaphthalyl, indanyl, and 1H-indenyl. Typically, heteroaryls include mono- or polycyclic radical of 5 to 12 atoms having at least one aromatic ring containing one, two, or three ring heteroatoms selected from N, O, and S, with the remaining ring atoms being C. One or two ring carbon atoms of the heteroaryl group may be replaced with a carbonyl group. Examples of heteroaryl groups are pyridyl, benzooxazolyl, benzoimidazolyl, and benzothiazolyl.
(35) The term substituent refers to a group substituted on, e.g., an alkyl, at any atom of that group, replacing one or more hydrogen atoms therein (e.g., the point of substitution). In some aspects, the substituent(s) on a group are independently any one single, or any combination of two or more of the permissible atoms or groups of atoms delineated for that substituent. In another aspect, a substituent may itself be substituted with any one of the substituents described herein. Substituents may be located pendant to the hydrocarbon chain.
(36) A substituted hydrocarbon group may have as a substituent one or more hydrocarbon radicals, substituted hydrocarbon radicals, or may comprise one or more heteroatoms. Examples of substituted hydrocarbon radicals include, without limitation, heterocycles, such as heteroaryls. Unless otherwise specified, a hydrocarbon substituted with one or more heteroatoms will comprise from 1-20 heteroatoms. In other embodiments, a hydrocarbon substituted with one or more heteroatoms will comprise from 1-12 or from 1-8 or from 1-6 or from 1-4 or from 1-3 or from 1-2 heteroatoms. Examples of heteroatoms include, but are not limited to, oxygen, nitrogen, sulfur, phosphorous, halogen (e.g., F, Cl, Br, I, etc.), boron, silicon, etc. In some embodiments, heteroatoms will be selected from the group consisting of oxygen, nitrogen, sulfur, phosphorous, and halogen (e.g., F, Cl, Br, I, etc.). In some embodiments, a heteroatom or group may substitute a carbon (e.g., substituted alkyl may include heteroalkyl). In some embodiments, a heteroatom or group may substitute a hydrogen. In some embodiments, a substituted hydrocarbon may comprise one or more heteroatoms in the backbone or chain of the molecule (e.g., interposed between two carbon atoms, as in oxa). In some embodiments, a substituted hydrocarbon may comprise one or more heteroatoms pendant from the backbone or chain of the molecule (e.g., covalently bound to a carbon atom in the chain or backbone, as in oxo).
(37) In addition, the phrase substituted with a[n], as used herein, means the specified group may be substituted with one or more of any or all of the named substituents. For example, where a group, such as an alkyl or heteroaryl group, is substituted with an unsubstituted C.sub.1-C.sub.20 alkyl, or unsubstituted 2 to 20 membered heteroalkyl, the group may contain one or more unsubstituted C.sub.1-C.sub.20 alkyls, and/or one or more unsubstituted 2 to 20 membered heteroalkyls. Moreover, where a moiety is substituted with an R substituent, the group may be referred to as R-substituted. Where a moiety is R-substituted, the moiety is substituted with at least one R substituent and each R substituent is optionally different (e.g., R may be independently selected at each occurrence from C.sub.1-C.sub.10 alkyl optionally comprising one or more points of substitution).
(38) Unless otherwise noted, all groups described herein (e.g., alkyl, cycloalkyl, heteroalkyl, acyl, heterocycloalkyl, aryl, heteroaryl, alkylene, heteroalkylene, cylcoalkylene, heterocycloalkylene) may optionally contain one or more common substituents, to the extent permitted by valency. Common substituents include halogen (e.g., F, C.sub.1), C.sub.1-12 straight chain or branched chain alkyl, C.sub.2-12 alkenyl, C.sub.2-12 alkynyl, C.sub.3-12 cycloalkyl, C.sub.6-12 aryl, C.sub.3-12 heteroaryl, C.sub.3-12 heterocyclyl, C.sub.1-12 alkylsulfonyl, nitro, cyano, COOR, C(O)NRR, OR, SR, NRR, and oxo, such as mono- or di- or tri-substitutions with moieties such as halogen, fluoroalkyl, perfluoroalkyl, perfluroalkoxy, trifluoromethoxy, chlorine, bromine, fluorine, methyl, methoxy, pyridyl, furyl, triazyl, piperazinyl, pyrazoyl, imidazoyl, and the like, each optionally containing one or more heteroatoms such as halo, N, O, S, and P. R and R are independently hydrogen, C.sub.1-12 alkyl, C.sub.1-12 haloalkyl, C.sub.2-12 alkenyl, C.sub.2-12 alkynyl, C.sub.3-12 cycloalkyl, C.sub.4-24 cycloalkylalkyl, C.sub.6-12 aryl, C.sub.7-24 aralkyl, C.sub.3-12 heterocyclyl, C.sub.3-24 heterocyclylalkyl, C.sub.3-12 heteroaryl, or C.sub.4-24 heteroarylalkyl. Further, as used herein, the phrase optionally substituted indicates the designated hydrocarbon group may be unsubstituted (e.g., substituted with H) or substituted. Typically, substituted hydrocarbons are hydrocarbons with a hydrogen atom removed and replaced by a substituent (e.g., a common substituent).
(39) In some embodiments, any hydrocarbon or substituted hydrocarbon disclosed herein may be substituted with one or more (e.g., from 1-6 or from 1-4 or from 1-3 or one or two or three) substituents X.sup.sub, where X.sup.sub is independently selected at each occurrence from one or more (e.g., 1-20) heteroatoms or one or more (e.g., 1-10) heteroatom-containing groups, or X.sup.sub is independently selected at each occurrence from F, Cl, Br, I, OH, OR*, NH.sub.2, NHR*, N(R*).sub.2, N(R*).sub.3.sup.+, N(R*)OH, N(.fwdarw.O)(R*).sub.2, ON(R*).sub.2, N(R*)OR*, N(R*)N(R*).sub.2, CNR*, NC(R*).sub.2, CNN(R*).sub.2, C(NR*)(N(R*).sub.2), C(H)(NOH), SH, SR*, CN, NC, CHF.sub.2, CCl.sub.3, CF.sub.2Cl, CFCl.sub.2, C(O)R*, CHO, CO.sub.2H, C(O)CH.sub.3, CO.sub.2, CO.sub.2R*, C(O)SR*, O(CO)H, O(CO)R*, SC(O)R*, (CO)NH.sub.2, C(O)N(R*).sub.2, C(O)NHNH.sub.2, OC(O)NHNH.sub.2, C(S)NH.sub.2, (CS)N(R*).sub.2, N(R*)CHO, N(R*)C(O)R*, C(NR)OR*, OC(NR*)R*, SCN, NCS, NSO, SSR*, N(R*)C(O)N(R*).sub.2, CH.sub.3, CH.sub.2CH.sub.3, CH.sub.2CH.sub.2CH.sub.3, C(H)(CH.sub.2).sub.2, C(CH.sub.3).sub.3, N(R*)C(S)N(R*).sub.2, S(O).sub.1-2R*, OS(O).sub.2R*, S(O).sub.2OR*, N(R*)S(O).sub.2R*, S(O).sub.2N(R*).sub.2, OSO.sub.3, OS(O).sub.2OR*, OS(O)OR*, OS(O)R*, S(O)OR*, S(O)R*, NO, NO.sub.2, NO.sub.3, ONO, ONO.sub.2, N.sub.3, N.sub.2R*, N(C.sub.2H.sub.4), Si(R*).sub.3, CF.sub.3, OCF.sub.3, OCHF.sub.2, OCH.sub.3, O(CH.sub.2).sub.1-6CH.sub.3, OC(H)(CH.sub.2).sub.2OC(CH.sub.3).sub.3, PR*.sub.2, OP(O)(OR*).sub.2, or P(O)(OR*).sub.2; where, independently at each occurrence, R* may be H or a C.sub.1-10 or C.sub.1-8 or C.sub.1-6 or C.sub.1-4 unsubstituted hydrocarbon, including without limitation alkyl, alkenyl, alkynyl, aryl (e.g., phenyl), alkyl-aryl (e.g., benzyl), aryl-alkyl (e.g., toluyl). In some embodiments, X.sup.sub may comprise a C.sub.1-C.sub.8 or C.sub.1-C.sub.6 or C.sub.2-C.sub.4 perfluoroalkyl. In some embodiments, X may be a C.sub.1-C.sub.8 or C.sub.2-C.sub.6 or C.sub.3-C.sub.5 heterocycle (e.g., heteroaryl radical). The term halo or halogen refers to any radical of fluorine, chlorine, bromine or iodine. In certain embodiments, X.sup.sub is independently selected at each occurrence from OH, SH, NH.sub.2, N(R*).sub.2, C(O)OR*, C(O)NR*R*, C(O)NR*R*, C(O)OH, C(O)NH.sub.2, F, or Cl.

In some embodiments, R* is hydrogen, or lower alkoxy (e.g., C.sub.1-C.sub.5 linear or branched alkoxy such as methoxy, ethoxy, propoxy, or isopropoxy). In some embodiments, X.sup.sub is CF.sub.3 or OCF.sub.3.
(40) It is understood by one of ordinary skill in the chemistry art that substitution at a given atom is limited by valency. The use of a substituent (radical) prefix names such as alkyl without the modifier optionally substituted or substituted is understood to mean that the particular substituent is unsubstituted. However, the use of haloalkyl without the modifier optionally substituted or substituted is still understood to mean an alkyl group, in which at least one hydrogen atom is replaced by halo. Where a group may be substituted by one or more of a number of substituents, such substitutions are selected so as to comply with principles of chemical bonding with regard to valencies, etc., and to give compounds which are not inherently unstable. For example, any carbon atom will be bonded to two, three, or four other atoms, consistent with the four valence electrons of carbon. Additionally, when a structure has less than the required number of functional groups indicated, those carbon atoms without an indicated functional group are bonded to the requisite number of hydrogen atoms to satisfy the valency of that carbon.
(41) The term pharmaceutical composition, as used herein, represents a composition containing a compound described herein formulated with a pharmaceutically acceptable excipient. In some embodiments, the pharmaceutical composition is manufactured or sold with the approval of a governmental regulatory agency as part of a therapeutic regimen for the treatment of disease in a mammal. Pharmaceutical compositions can be formulated, for example, for oral administration in unit dosage form (e.g., a tablet, capsule, caplet, gel cap, etc.); for topical administration (e.g., as a cream, gel, lotion, or ointment); for intravenous administration (e.g., as a sterile solution free of particulate emboli and in a solvent system suitable for intravenous use); or in any other formulation described herein (see below).
(42) Catalyst as used herein typically is a disubstituted quadracycle (such as 6,12-substituted chrysene), unless otherwise specified. Specific substitutions on the catalysts of the present disclosure include hydroxyalkoxy substitution such as hydroxyethoxy substitution at the two positions.
(43) Substrate as used herein typically is a tetra substituted quadracycle (such as 3,6,9,12-substituted chrysene, unless otherwise specified. Specific substitutions on the substrates of the present disclosure include hydroxyalkoxy substitution such as hydroxyethoxy substitution at the four positions.
(44) The regulatory sequence typically is present at an end group pairing of the SCH complex and may involve an associated regulatory molecule and catalyst. Regulatory molecules are typically tri substituted quadracycles (such as 3,6,12-substituted chrysene), unless otherwise specified. Specific substitutions on the regulatory molecules of the present disclosure include hydroxyalkoxy substitution such as hydroxyethoxy substitution at the four positions.
(45) SCH Complex herein typically refers associated pairings of substrate and catalysts (or catalysts and regulatory molecules). These associations may occur though stacking of the aromatic ring systems of the substrate/catalyst and regulatory molecule/catalyst. These associations may be in heterodimeric form or through covalent conjugation through the substitutions as described herein. The SCH Complex may also include adjacent substrate/catalyst pairings as well, often associated vi stacking of the substrate from one heterodimer (or molecule if the substrate is covalently conjugated to the catalyst in one reaction vessel) to the catalyst of another adjacent heterodimer (or molecule if the substrate is covalently conjugated to the catalyst). SCH Sequences involve two or more associated heterodimers or molecules which may undergo the reactions described herein to form DNA, RNA, and/or DNA/RNA hybrids.
(46) Reaction Vessels as used herein are typically individual pairings of moieties that undergo stacking with one another. The reaction vessel may include dimerized forms (such as by two compounds having the structure of formula (I), or a molecule having two moieties comprising polycyclic moieties with systems bonded to one another and oriented in a manner to encode information (e.g., via unaligned or aligned orientations of the systems).
(47) As used herein, the phrase pharmaceutically acceptable generally safe for ingestion or contact with biologic tissues at the levels employed. Pharmaceutically acceptable is used interchangeably with physiologically compatible. It will be understood that the pharmaceutical compositions of the disclosure include nutraceutical compositions (e.g., dietary supplements) unless otherwise specified.
(48) Unit dosage forms, also referred to as unitary dosage forms, often denote those forms of medication supplied in a manner that does not require further weighing or measuring to provide the dosage (e.g., tablet, capsule, caplet, etc.). The compositions of the present disclosure may be present as unit dosage forms. For example, a unit dosage form may refer to a physically discrete unit suitable as a unitary dosage for human subjects and other mammals, each unit containing a predetermined quantity of active material calculated to produce the desired therapeutic effect, in association with any suitable pharmaceutical excipient or excipients. Exemplary, non-limiting unit dosage forms include a tablet (e.g., a chewable tablet), caplet, capsule (e.g., a hard capsule or a soft capsule), lozenge, film, strip, and gel cap. In certain embodiments, the compounds described herein, including crystallized forms, polymorphs, and solvates thereof, may be present in a unit dosage form.
(49) Useful pharmaceutical carriers, excipients, and diluents for the preparation of the compositions hereof, can be solids, liquids, or gases. These include any and all solvents, dispersion media, coatings, antibacterial and antifungal agents, isotonic and absorption delaying agents and the like. The pharmaceutically acceptable carrier or excipient does not destroy the pharmacological activity of the disclosed compound and is nontoxic when administered in doses sufficient to deliver a therapeutic amount of the compound. Thus, the compositions can take the form of tablets, pills, capsules, suppositories, powders, enterically coated or other protected formulations (e.g., binding on ion-exchange resins or packaging in lipid-protein vesicles), sustained release formulations, solutions, suspensions, elixirs, and aerosols. The carrier can be selected from the various oils including those of petroleum, animal, vegetable or synthetic origin, e.g., peanut oil, soybean oil, mineral oil, and sesame oil. Water, saline, aqueous dextrose, and glycols are examples of liquid carriers, particularly (when isotonic with the blood) for injectable solutions. For example, formulations for intravenous administration comprise sterile aqueous solutions of the active ingredient(s) which are prepared by dissolving solid active ingredient(s) in water to produce an aqueous solution and rendering the solution sterile. Suitable pharmaceutical excipients include starch, cellulose, chitosan, talc, glucose, lactose, gelatin, malt, rice, flour, chalk, silica, magnesium stearate, sodium stearate, glycerol monostearate, sodium chloride, dried skim milk, glycerol, propylene glycol, water, and ethanol. The compositions may be subjected to conventional pharmaceutical additives such as preservatives, stabilizing agents, wetting or emulsifying agents, salts for adjusting osmotic pressure, and buffers. Suitable pharmaceutical carriers and their formulation are described in Remington's Pharmaceutical Sciences by E. W. Martin.

(54) The term effective amount or therapeutically effective amount of an agent (e.g the combination of cytokines and quinine derivatives described herein), as used herein, is that amount sufficient to effect beneficial or desired results, such as clinical results, and, as such, an effective amount depends upon the context in which it is being applied.

(56) Provided herein are compounds, systems, methods of use, and methods of construction independent reaction vessels, and stacked versions thereof, that may be able to contain information (e.g., base two information, base four information). The information is contained in a the relative orientations of a substrate and catalyst, which, when coupled to adjacent substrate and catalyst pairs contain four independent bits of information. These substrate and catalyst pairs (also referred to herein as reaction vessels), may undergo certain synthetic transformation to result in DNA/RNA or hybrids thereof and/or phospholipids (which may form bilayers and, eventually a cellular membrane).
(57) Primer for Encoding DNA as Coupled Binary Molecular Sequences
(58) Without wishing to be bound by theory, the development of the code and the associated molecular structures to encode DNA and RNA described herein begins with a detailed examination of the DNA molecule.
(59) In
(60) Analysis described herein of these pairings identifies a common structure, comprised of a fusion of four-rings in the shape of a steroid molecule, is incorporated within the structure of each nucleotide pair.
(61) As the common structure of the four nucleotide pairings identified herein generally has a steroid core, the structural correspondence of steroid molecules with each nucleotide pairing is informative. For example, A-T nucleotide pairings possess only two internal hydrogen bonds and C-G pairings which have three internal hydrogen bonds is of considerable importance. In
(62) An analysis of the C-G pairings, which already have three internal hydrogen bonds, provides a correlation with another type of nuclear steroid hormone. Similarly to the complementary match between cortisol and the A-T dinucleotide, as shown in
(63) Without wishing to be bound by theory, the symmetric and complementary relation of the steroid hormones with DNA provides a predictive capability for the pharmacological efficacy of synthetic corticosteroids. In particular, the observation of a structural match to produce the third hydrogen bond with A-T is of a functional nature. The intermolecular strength of the hydrogen bond with the unpaired ketone group of thymine may be examined by comparative assessment of the potency of dexamethasone, prednisolone, prednisone relative to cortisol. The relative activity of dexamethasone:prednisolone:cortisol is approximately 25:4:1 and that prednisone, in its native form, is inactive as it must be converted into prednisolone in the liver before it can be used. By analyzing the strength of the potential hydrogen bond with thymine, the pharmacological efficacy data is predictable. The structural relationship of prednisolone to thymine is shown in
(64) Potency is consistent with the hypothesis that the intermolecular bond between endogenous steroids and the A-T dinucleotide is of a functional correlation. Represented in
(65) The thymine ketone hydrogen bond is implicated in activity, despite it not forming any hydrogen bonds in nucleotide pairings. Because of both structural and functional correlations, the interaction of a second intercalated molecule with DNA at the unpaired thymine ketone may be the reason for the absence of this ketone hydrogen bonding during the formation of the A-T pairing. Thus, an explanation for the shape of a four-ring structure common to each nucleotide paring and the interaction of this common shape molecule with the A-T pairing and lack of interaction with the C-G pairing constitute the partial premise the present description considers. These similarities are particularly relevant to help provide common structures that are able to provide the same information as DNA and/or RNA and may be used to synthesize DNA/RNA.
(66) An underlying code for DNA using a common structure is shown in
(67) Consequently, the two binary molecules (e.g., configured as indicated in
(68) The relation of the base-two molecules described herein to describe a base-four entity of nucleotide pairings is bijective. The first base-two molecule (or catalyst) describes an intermolecular association of interaction with the second base-two molecule to prevent the formation of the third hydrogen bonding during nucleic acid synthesis, and the second base-two molecule, considered as the substrate, defines a shape that characterizes the spatial orientation of purine and pyrimidine nucleotides. Therefore, the four possible configurations of nucleotide pairings may be directly mapped to relative orientations of substrate/catalyst pairings dependent on the molecular form of the catalyst and substrate.
(69) Source and Starting Molecules
(70) To implement the code outlined in
(71) The implications of the present disclosure to the origin of DNA also may help construct and identify suitable molecules and reaction vessels. For example, the search for the molecules may be narrowed by considering that a sequence needs to self-assemble (e.g., based on available chemicals and rection environments encountered at first synthesis). For example, aromatics, particularly polycyclic aromatic hydrocarbons, are readily produced in combustion reactions and present in the atmosphere. Suitable candidates for substrates and catalysts may therefore be aromatic compounds that can achieve -electron stacking with one another. Typically, to achieve the common structure identified in nucleotides pairs, a four-ring molecule can be sought (e.g., chrysene, heterochrysene which is meant a chrysene core having one or more heteroatom substitutions (e.g., N, O, S) in the four-ring structure core). Furthermore, although not a requirement for the encoding method to work, ideally the molecular basis should be produced by natural occurrences. In research embodiments for reviewing and/or identifying the origin of DNA, then the molecules should meet this requirement. These methods may involve synthesizing a catalyst and substrate, reviewing the self-assembly mechanisms, for the catalyst and substrate, and initiating (or attempting to initiate) a DNA synthesis such as a DNA synthesis cascade initiated by ozonolysis as described herein.
(72) Chrysene, shown in
(73) It is noted that chrysene is a symmetric molecule, whereas DNA is a non-symmetric molecule in terms of ring structure as shown outlined in
(74) To develop sidechains for chrysene for use as a catalyst and substrate undergoing a reactive transformation, there are also several requirements from the base chrysene material. For example, as chrysene is insoluble in aqueous, and thus to make it soluble, the sidechains may induce hydrophilicity. One method of producing sidechains on chrysene of the present disclosure involves halogenation of chrysene (e.g., at higher temperatures for an extended periods of time to introduce functionalization at the appropriate positions), followed by subsequent conversion of the halogen sidechain to the desired group. During the halogenation process, as shown herein, there is an order of appearance of the sidechains on the aromatic rings. In some environments, the halogenation process will produce multiple halogenated products that occur at different times while transitioning to a final product.
(75) Exemplary molecules of the present disclosure capable of inducing encoded molecular sequences of RNA and DNA (as well as phospholipids for cell membranes) are presented as follows:
(76) The production of the end groups associated with the starting materials are consistent with natural occurrences as well as synthetic methods. Relevant positions for substrate and catalyst creations on chrysene become brominated sequentially. As shown herein, experimental results of a four-day bromination process of chrysene involving reaction with bromine (Br.sub.2) in the presence of trimethyl phosphate show that after approximately one day the (6,12) positions are only brominated and brominated in a simultaneous manner. The bromination process involves the dilution of bromine with trimethyl phosphate to develop a reaction mixture with chrysene (e.g., at an elevated temperature such as 100 C.) for a period of time such as three days. After the formation of the 6,12 substituents, the 3 position becomes brominated to result in (3,6,12) tribromochrysene. Finally, the full (3,6,9,12)-tetrabromochrysene completes the reaction (with the experimental conditions, seventy-two hours of reaction time). The amount of trisubstituted product is low, less than 5% (by mol), with the majority of product disubstituted and tetrasubstituted product. Bromination reactions can occur at high rates with less than 2 mol % chrysene remaining, and with minimal monobromosubstituted chrysene compounds (e.g., less than 2 mol %).
(77) The halogenated sidechains may be used to install more specific groups such as alkoxy groups on the central polycyclic core consistent with the asymmetries in the substrate and catalyst (particularly in the encoding and the DNA/RNA syntheses described herein). For example, installation of an oxalate-based (e.g., OC(O)C(O)O) or ethylene glycol-based sidechain e.g., OC(R.sub.2)C(R.sub.2)O, wherein R is independently selected at each occurrence from hydrogen or alkyl (e.g., lower alkyl, C.sub.1-6 alkyl) or two geminal R groups may together form O),) at the carbon 12 position of chrysene is consistent with the positioning of the hydroxyl group at the carbon-11 position of steroids matching the primer shape identified in
(78) The four-ring shape, which relates to the common shape of the primer structure, as well as the positioning of the side-chain elements, and the consistency with the natural appearance of sidechains, suggest that starting materials, such as those in of
(79) Encoded Sequences by T-Electron Stacking of Substituted Chrysene
(80) In
(81) A sequence of heterodimers may form a useful segment of RNA or DNA is depicted in
(82)
(83) The alignment of the catalyst to the substrate typically defines the resultant nucleotide by the production of the three hydrogen or two hydrogen bonds linking the paired resultant nucleobases. The alignment contributes to the formation of the reaction environment from which the nucleobases may be subsequently synthesized. In
(84) Trisubstituted compounds, such as 3,6,12-trisubstituted chrysene functions as a regulator (or initiator) for the code (and any resultant sequence) as these compounds terminate the polymerization process. Polymerization is terminated due to a lack of a sidechain at the 9 position in the compound, therefore preventing conjugation for any further substrate/catalyst pair. The relative orientation of the regulator (or initiator) compound may also inform the directionality of the encoded sequence. For example, the production of RNA expressed as 3-5 may be initiated by the orientation of the molecular initiator shown in
(85) Code for DNA and RNA
(86) The -stacked arrangement of reaction vessels (e.g., heterodimers) of catalysts (e.g., 6,12-dihydroxyethoxy chrysene) and substrates (3,6,9,12-tetrahydroxyethoxy chrysene), optionally capped (at one or both ends) with reaction vessels (e.g., heterodimers) comprising initiator (e.g., 3,6,12-trihydroxyethoxy chrysene) and catalyst provides the requisite basis for information. These stacked reactionvessel may define codes which correlate to RNA and/or DNA based on the relative orientation of the four reaction vessels possible of the heterodimers. For 5-3 direction in any DNA/RNA synthesized, in
(87) In
(88)
(89) In some embodiments, the polymerization process takes place between sequential substrates separated with the catalyst without requiring the presence of the regulator. The direction and code may proceed thereby in an indeterminate fashion in terms of the initiating coupling by phosphorylation between adjacent substrates (e.g., 2,2,2,2 -(chrysene-3,6,9,12-tetrayltetrakis(oxy))tetrakis(ethan-1-ol)). However, certain arrangements of reaction vessels may proceed more rapidly than others depending upon, for example, the physical distance between adjacent sidechains which conduct the polymerization between neighboring substrates. Moreover, the catalyst arrangement between substrates may hamper the polymerization by physically blocking formation of the nascent phosphodiester linkage. Thus, certain arrangements, such as TTTT as compared to TATA have different probabilities of polymerization to initiate and to terminate a sequence. Consequently, the initiator is optional, inasmuch as the substrate (e.g., 2,2,2,2 -(chrysene-3,6,9,12-tetrayltetrakis(oxy))tetrakis(ethan-1-ol)) may be sufficient to serve as the regulatory and direction encoding compound in certain sequences.
(90) Reaction for Synthesis of Encoded DNA and RNA
(91) The reactive transformation of T-stacked catalysts and substrates (e.g., substituted chrysene) to DNA and RNA may follows Hckel [4n+2] aromaticity. For example, the starting material chrysene has four rings and is aromatic for a total of eighteen ring -electrons. Initiating a reaction in chrysene (or substituted chrysenes such as the substrate) within a -stacked framework may induce a stepwise set of reactions in which the end product has regained planarity, aromaticity and -electron connectivity to the adjacent aromatic catalyst of substituted chrysene. For example, the end-result may be an aromatic substituted purine which has ten ring -electrons and an aromatic substituted pyrimidine which has six ring -electrons:

(119) The reaction mechanism may proceed as follows. The first step in the reaction may involve the opening of the outer rings and then the inner rings through an oxidative cleavage process. For example, the reaction may involve the following chemical reaction:
(120) ##STR00025##
wherein R.sub.3, R.sub.6, R.sub.9, R.sub.12, m, and n are defined as described herein and X.sub.1 is absent (e.g., when the carbon it is attached to is unsaturated such that is a double bond at that position) or OH. Oxidative cleavage may occur, for example, via ozonolysis with ozone (O.sub.3) or with other suitable oxidants and/or oxidative catalysts such as O.sub.2, permanganates (e.g., KMnO.sub.4), chlorites (e.g., RuCl.sub.3), nitroarenes (e.g., photoexcited nitroarenes) or OsO.sub.4NaIO.sub.4 reaction schema. During this oxidative process, the atoms of the outer ring that are liberated through the cleavage of the bond may be rotated into position through attachment to the 4 carbon on the sidechain. For example, when the original substrate core has at least one terminal six membered aromatic ring (and X.sub.1 is OH), and, 1R.sub.3 is OCH.sub.2CH.sub.2OPO(OH.sub.2), the presence of water may induce sugar ring formation:
(121) ##STR00026##
The right-hand ring may undergo a rotational process of the entry point whereby nitrogen is inserted through the double bonds (which may be ascertained based on the directionality of the phosphodiester linkage,). This insertion may occur at both sides of the structure as the flexure of the outer ring into position induces stresses that are relieved through incorporation of nitrogen. In some embodiments, there are a total of five nitrogen insertions throughout the molecule. For example, the synthesis may involve:
(122) ##STR00027## ##STR00028##
(123) In some embodiments, the compound may undergo a ring opening mechanism (e.g., when the chemical intermediate involves a seven membered fuse ring following nitrogen insertion). The rings (e.g., three rings) may be closed through the development of a nitrogen-carbon bond. The six-membered ring of purine is closed through first the formation of an imine and then NC bond formation. Imine formation may occur via ring opening (e.g., of a seven membered ring). Afterwards, the side groups finish processing, and are controlled through the alignment of the catalyst to the substrate. In this case, the catalyst is unaligned and would provide a three-hydrogen bond coupling through an arrangement of carbonyl and amine groups. Example 20 provides details on the interaction of the catalyst and substrate as a function of aligned and unaligned configurations. Finally, the catalyst and substrate are separated at the (6,12) binding locations for the C-G configuration, but for the A-U and A-T pairings the catalyst remains attached to adenine.
(124) Conditions for Reactions
(125) There are three steps to form the DNA and RNA nucleotide: 1) provide the substrate/catalyst/initiator (e.g., chrysene-based starting materials), 2) assemble the starting materials into a sequence of -stacked molecules, and 3) initiate a reaction within the sequence to trigger a cascade of reactive events to form the final product.
To achieve the final product, two approaches are considered: the first method which applies chemical processes and materials that are nominally available within a natural setting and the second method which adopts laboratory synthesis methods as a replacement for natural processes that may improve reaction times, reaction yields, or enhance convenience of demonstration.
(126) In some embodiments, the formation of a sequence final product can either be performed in a random way or in a directed way. In a directed manner, the target nucleotide sequence is specified, and then, during the assemble step, the binary molecular substitutes of chrysene may be arranged according to the encoding schemes described herein such as those coding provided in
(127) The formation of the starting molecules may begin with the halogenation of a substrate core such as chrysene. The core may be di, tri, or tetra substituted dependent on if a catalyst, substrate, or initiator is being synthesized. The halogenated material may be then turned into a phenolic compound via reaction replacing the halogens are each replaced with a hydroxyl group. The hydroxyl groups may then be used to form ethoxylated alcohol at the originally halogenated positions.
(128) An exemplary halogenation process is bromination of the core. Bromination may occur in a flask with the unsubstituted core (e.g., chrysene) dissolved in a suitable solvent such as trimethyl phosphate. The mixture may be heated (e.g., to from 30 C.-100 C. such as 60 C.). Once heated, bromine may then be added dropwise, and the reaction mixture heated more (e.g., to more than 100 C. (e.g., 100 C.-200 C., 100 C.-150 C., 120 C.) for a period of time for the reaction to occur. The period of time may alter the end product. For example, (6,12)-dibromochrysene is present first (e.g., in a day). Next, (3,6,12)-tribromochrysene may be formed in the second to third day for a brief period, and finally the (3,6,9,12)-tetrabromochrysene molecule results. The reaction mixture does not proceed further (but may also be stopped after formation of the tetra substituted core).
(129) The conversion of the brominated side-groups to the ethoxylated alcohol surfactants may be accomplished by replacement of the halogen groups with hydroxyl groups (e.g., conversion to a phenolic compound) which may then be converted to an ethoxylated alcohol. This can be performed by taking the mixture of the halogenated core (e.g., di, tri, or tetra substituted bromochrysene) in a solvent mixture of CuI NaOMe (e.g., from 10%-40% NaOMe by weight such as 28% NaOMe by weight) in MeOH over dimethylfuromide (e.g., at greater than 100 C. such as 120 C. to replace the halogenated groups with a methoxy group. Next BBr.sub.3, DCM may convert the methoxy to a hydroxy (e.g., and prepare the phenolic compound). Ethyl bromoacetate converts may be used to convert hydroxyl groups to ethoxy ethanoic ester, which when combined with LAH, THF may convert the material to ethoxylated alcohol substituted core (e.g., on chrysene at the (6,12); (3,6,12); or (3,6,9,12) carbon locations).
(130) In particular embodiments, the ethoxylated alcohol substrates/catalysts may be used to encode information and/or synthesize a sequence of nucleotides. For example, to develop the sequence, when a mixture of ethoxylated catalysts and substrates are phosphorylated with POCl.sub.3 and tetramethylpipeidine (TMP) with a proton sponge, heterodimers may be formed. For example, the substrate and catalyst may have the structure:
(131) ##STR00029##
These catalysts and substrates may self-assemble in the suitable reaction environment into Aligned and Unaligned forms. Self-assembly may be controlled by solvent such that the differences in solubility between substrate and catalyst in the solvent. For example, using chrysene as the core structure, (6,12) and (3,6,9,12) substituted chrysenes may preferentially dimerize because of comparatively lower steric hindrance and higher solubility relative to the alternative homodimer forms of (6,12); (3,6,9,12); or (3,6,12) substituted chrysene. The assembly of the heterodimers, in a suitable reaction environment (e.g., POCl.sub.3 and tetramethylpipeidine (TMP) with a proton sponge), may result in a linked sequence through the (6,12) connections forming phosphodiester linkages between adjacent chrysene-based molecules to form a heterodimer. Each reaction vessel may also be stabilized into a sequence with -stacking stabilizing the heterodimers (or conjugated substrate/catalyst pairs). This -stacked arrangement or sequence is performed preferably before the phosphorylation process. It may be developed as a one pot synthesis in which reactive hydrophobic domains are dispensed throughout a hydrophilic environment.
(132) The transformation from the sequence of substituted chrysene to DNA and RNA is accomplished preferentially through anerobic means. Oxidative cleavage may open the core rings (typically one or both of the terminal optionally aromatic core rings) which may begin the conversion. Oxidative cleavage may be performed under anerobic conditions through nitroarene chemistry using the (6,12) substituted core (e.g., (6,12) substituted chrysene) as the aromatic catalyst to induce regioselective ring opening of the substrate as an effective oxygen transfer agent through interaction with reactants including NO.sub.2. (See
(133) The reaction mixture may be run in acidic conditions such as with aqueous concentrations of, for example, nitric acid (HNO.sub.3), sulfuric acid (H.sub.2SO.sub.4), phosphoric acid (H.sub.3PO.sub.4), and/or ammonia (NH.sub.3) and at a temperature of, for example, 30 C. to 120 C. To form nitroarene, nitric acid and concentrated sulfuric acid may be used on the chrysene-based substrate. The stabilizing sidechains enable milder conditions with the subsequent additions of NO.sub.2 groups requiring aggressive temperature as the reaction proceeds. Sulfuric acid may be added to the reaction in in its concentrated form to induce the acidic conditions. Metal of palladium as a catalyst may be used to promote ring closure and imine formation as has been reported, such as in Yu, Bangkui et al., J. Am. Chem. Soc. 142.43 (2020): 18341-18345, which is hereby incorporated by reference in its entirety, consistent with the cleavage and reformation with nitrogen incorporation in ring structures. ZnO and Mg are other choices for metal co-reactants. Photochemical stimulation may occur through application of UV light, purple light, white LED light, light having a wavelength (or .sub.max) of 365 nm to 440 nm may be deployed. Electromagnetic radiation for photochemical stimulation of reaction mixtures may have a radiant flux of, for example, 100 to 600 W/m.sup.2. Alternative wavelengths are useful in accelerating the reaction including the use of other visible and UV light wavelengths. In various embodiments, the light may have a spectrum similar to sunlight.
(134) In some embodiments, nitroarene based oxidative cleavage may occur in the presence of acetonitrile. The addition of acetonitrile, such as disclosed in Wise, D, et al. J. Am. Chem. Soc 144.34 (2022): 15347-15442, which is hereby incorporated by reference, may be advantageous in several nitroarene chemical reactions of the present disclosure. The reaction may proceed over the course of, for example, 1 minute-1 week (e.g., two or more minutes to two or more days) and optionally include a triggering step of aromatic ring opening of the substrate core. Ring opening may initiate the cascade reaction. Furthermore, to improve reaction yield, an electrochemical gradient may be held in the reaction medium to, for example, assist with the nitrogen insertion. Nitrogen insertion may increase the atom number of the resultant rings after the initiating rings are opened through the oxidative cleavage process. The addition of molecular oxygen, a carbonate such as K.sub.2CO.sub.3 and methanol solvent may also improve the conditions for oxidative cleavage. In some embodiments, degassing the reaction mixture of molecular oxygen may afford running a more anerobic process and enhance regioselectivity.
(135) Oxidative cleavage occur via ozonolysis with an ozone generation source followed by reductive workup. In some embodiments, oxidative cleavage may be accomplished with Lemieux-Johnson method using OsO.sub.4 or KMnO.sub.4 followed by NaIO.sub.4. Reactants may include water, ozone, permanganates (KMnO4), phosphates such as ammonium phosphate and sodium phosphates, alcohols such as methanol, carbonates such as K.sub.2CO.sub.3, ammonia, nitrates, nitric acid, sulfuric acid, phosphoric acid, and ammonium salts such as ammonium halides.
(136) After the initial oxidation, the reaction typically proceeds to completion as the reaction environment is constrained both spatially, due to the -electron connectivity of adjacent molecular objects, and constrained chemically, through the hydrophobic core of the aromatic molecules surrounded by a hydrophilic environment. As explained herein, aromaticity is maintained and may involve a transformation from eighteen -electrons in one molecule (e.g., of four aromatic rings) to sixteen -electrons in two separate molecules having three total rings, wherein the two separate molecules typically also are connected to a sugar-ring each, of which the two -electrons of the eighteen -electrons are used in its formation, and which affords hydrophilicity of the compound during synthesis.
(137) Therefore, the present disclosure provides for the development of the synthesis environment for breaking aromatic rings through oxidative cleavage in a regioselective manner. These synthesis environments may provide sufficient free nitrogen for insertion into the molecular arrangement which may achieve sufficient planarity and aromaticity.
(138) Formation and Separation of Nucleic Acid and Phospholipid Bilayer Materials
(139) To prevent degradation and to serve as a reaction chamber for protein synthesis after development of RNA and DNA, it is typically necessary to have a cellular membrane. The processes of synthesis of DNA and/or RNA described herein also includes the materials and mechanisms for the formation of a cellular membrane. Methods are therefore also provided for the generation of phospholipids using the syntheses from substrate/catalyst pairings described herein. In
(140) Saturated phospholipids may be formed through several oxidative cleavages of the phospholipid remnants comprising the catalyst core. For example, chrysene includes 18 carbons. Repeated oxidative cleavages of phospholipid remnants may result in two phospholipids having the structure such that the acetyl core carbons are present in the terminal saturated acetal. The sum of carbons in the terminal saturated acetal groups may be 18. Repeated oxidative cleavage of a Cn core (e.g., n referring to the number of carbons in the core such as from 15-25, chrysene would be a C.sub.18 core) may result, for example, in a first and second phospholipid each having the structure HOCH.sub.2CH.sub.2OP(OH).sub.2OCH.sub.2CH.sub.2R.sub.1, wherein R.sub.1 is independently a C.sub.m saturated hydrocarbon and m is independently an integer from 1 to 1-n such that m1 (the m in C.sub.m for the first phospholipid)+m2 (the m in C.sub.m for the second phospholipid) sum to n.
(141) Methods to generate phospholipids may also include forming independent homodimers of the (6,12)-disubstituted catalysts. These methods may be useful for creation of general populations of the cellular construct. Furthermore, in some embodiments, amino acid syntheses are available all through the decomposition of the (6,12) disubstituted chrysene catalyst (see Example 11).
(142) As the phosphodiester linkage of the catalyst to adenine of RNA remains after synthesis, linkage of the RNA molecule to specific positions of the cellular membrane may be designed. This is appropriate for an encoded mapping between the phospholipid bilayer material and RNA. This encoded signal mechanism is useful for sending coordination information from a membrane to the genetic material during the first cellular divisions.
(143) In
(144) The solution in which the sequence is synthesized is typically rich in nitrogen containing species (e.g., contains more than 20% by weight nitrogen containing species such as ammonia). A reaction then takes place to convert the assembly into a combination of DNA and RNA sequences, as well as hybrid DNA/RNA sequences. The reaction typically follows a stepwise procedure of oxidative cleavage followed by nitrogen insertion and ring closure steps. The alignment of the catalyst to the substrate determines the nucleobases synthesized. The directionality and hence code that is applied is determined through the tri-substituted chrysene molecules present in the reaction vessel stack. The specific chemical steps to induce the reactions, particularly oxidative cleavage, may be performed via an anerobic chemistry route (which is consistent with the atom economy demonstrated in the reaction sequence). For example, oxidative cleavage may be performed through photon-enhanced nitroarenes set-up through aromatic catalyst -coupled with the substrate. Alternatively, ozonolysis or metal-based oxides can be deployed for oxidative cleavage. Electrochemical gradients can assist with nitrogen insertion.
(145) During the nucleic acid product formation, the phospholipids may be produced as a cell membrane, and thus the composite cell can proceed to implement the instruction set provided by the RNA sequence, as well as the DNA/RNA composite product. This RNA instruction set is typically used for the first few cellular divisions at which point the DNA takes control and implements its instruction set for the cell. The hybrid set of DNA/RNA may be useful to implement the genetic code through the formation of ribosomal units.
(146) Applications
(147) Applications for the techniques described herein have utility in several fields including informatics, regenerative medicine, genome synthesis, artificial totipotent stem cell therapy, and life synthesis. These also relate to several areas of chemical reactions including conducting reactions in chemically and spatially constrained areas and polymerization of polyaromatic compounds. The process also relates to areas of nanotechnology including computation, display, and information processing.

(153) Alterations
(154) This invention source materials are primarily exemplified by chrysene-based derivatives. The concepts extend to the other four-ring structures, such as pyrene, and to chrysene with other appropriate sidechains. The invention extends to polyaromatic hydrocarbons other than chrysene such as those having the structure:
(155) ##STR00030##
(156) In addition, analogous to the extension of phosphodiester chains to progress from adenosine monophosphate to adenosine triphosphate, the use of multiple phosphodiester groups to the sidechains of the catalysts, substrates, and regulators (initiators) may introduce additional energy to the system of molecules, which may be useful for inducing chemical reactions.
(157) Also included in the disclosure is the opportunity for a code that considers the unalignment of the catalyst to the substrate as the basis for protecting the unpaired ketone during the nucleotide formation process. In this embodiment, the Forward or Backward configurations would correspond to be considered as F for protective and B for non-protective. Although specified as the opposite alignment configuration, the code is as described in the primer,
(158) The disclosure also includes reagents and intermediates of the reactions, for example, phosphoramidites (such as those associated with spectra in

These are not to be considered as a limitation to the scope of the claimed embodiments. SCH denotes Substituted Chrysene Heterodimer to represent the association of 2,2-(chrysene-6,12-diylbis(oxy))bis(ethan-1-ol) and 2,2,2,2-(chrysene-3,6,9,12-tetrayltetrakis(oxy))tetrakis(ethan-1-ol) coupled through a monophosphate at the (6,12) positions as shown in

Example 4: Regulatory Sequences
(166) In
(167) After reactivity of this regulatory reaction vessel, the result is a 5-cap structure for RNA, which can be used as a signal to initiate translation. It is also noted that the triphosphate association of 5-cap structure on mRNA is consistent with the method of initiating polymerization through phosphorylation of the 3,9 sidechains of the sequence of tetrasubstituted chrysene.
(168) In addition, regulation is provided by sequences of the (3,9) polymerization induced by the sequential orientation of 2,2,2,2-(chrysene-3,6,9,12-tetrayltetrakis(oxy))tetrakis(ethan-1-ol). For example, consider the repetitive sequence:
(169) TABLE-US-00011 TTTTAAAAA
(170) In this sequence, the orientation of the entry point at the downstream position of AAAAA is consistent with a 5-RNA configuration; and likewise, the upstream condition of TTTT has AAAA on 3 side, and thus on the reverse strand, the preferred orientation is also of a 5 to 3 RNA configuration.
Example 5: Hybrid DNA: RNA Encoding
(171) With the upstream regulatory sequence coding for DNA at 5 and a downstream regulatory sequence coding on the antiparallel side of the molecule and encoding for RNA and 5, the result is a hybrid DNA/RNA. An example is presented below in which the decoding was performed by using the table of

Example 6: Simulation of Base-Four -Electron Stacked Structure
(173) Simulation of the catalyst-substrate combination in the formation of base-four structure enabled through -electron stacking was performed.
(174) The alignment determines whether the resultant structure has two or three intramolecular bonds, while the regulatory sequence determines which side of the molecule, the polymerization will take place, and thus determine whether a purine or pyrimidine is 5 structure as dictated by the entry position of the sugar ring.

Example 8: Modeling and Simulation

(184)
(185) To simulate sugar-ring closure, SCH compounds as a -electron stacked assembly are processed by applying an oxidative cleavage, preferably under green chemistry conditions using anerobic procedures with a mixture of ammonia, sulfuric acid, nitric acid, water, phosphoric acid, and a metal such as zinc oxide or magnesium under visible light. Other methods of oxidative cleavage are also described herein including ozonolysis. As modeled in

Example 10: SCH Sequence Design for Implementation of First Instruction Set
(189) The described method is capable of producing RNA concurrently with DNA and hybrid DNA/RNA, and thus proteins for the first instruction set can be developed from RNA. One area to consider however is that for implementing the first instruction set the proteins are not available to stabilize RNA in order to perform translation. This can be resolved through efficient design of RNA in conjunction with the catalyst for implementing the first instruction set. As mentioned, the interaction of the catalyst from RNA-adenine, which is connected at the 6-position of the (6,12)-disubstituted chrysene to the carbon of RNA-adenine without a sidechain, may remain. This can be exploited therefore to stabilize RNA by maintaining a connection with the catalyst, which is a phospholipid bilayer. Thus, the catalyst and remnant after synthesis can remain attached to RNA through a sequential adenine group at the post-coding area to stabilize through association with the cellular membrane. For a long sequence of RNA-adenine, the catalyst attached to the RNA and the membrane will provide sufficient stability for translation of the RNA molecule. This approach is equivalent to the poly-A tail of mRNA. Thus, the sequence for translated RNA for implementing the first instruction set should include the SCH sequence:
(190) TABLE-US-00012 FFFFFFFFFFFFFFFFFFFFFFFFFF= AAAAAAAAAAAAA
(191) For implementation of the first instruction set, this relation between adenine attached to the catalyst remnant is illustrated in
Example 11: Supportive Molecules from Homodimers of Substituted Chrysene
(192) While the heterodimers produce the nucleic acids as well as encoded phospholipid structures for interaction with membranes, to produce the cellular structure and engage in protein synthesis, amino acids as well as non-encoded phospholipid structures are required. These materials are available from the phosphorylated homodimers of the naturally produced substituted set of chrysene molecules, comprised of 6,12-disubstituted chrysene, 3,6,12-trisubstituted chrysene, and 3,6,9,12-tetrasubstituted chrysene.
(193) Anaerobic oxidative cleavage, reduction, and polyarene nitrogen insertion, hydroamination, and imine formation will enable these structures in a manner consistent with encoded nucleotide synthesis. In
Example 12: Application to Biosynthesis
(194) While the developments have application in areas of genome synthesis and regenerative medicine, the method and means for the design and synthesis of encoding nucleotides and phospholipids described within have utility in many areas including in research directed towards life synthesis, informatics, or investigations into origins of life.
(195) In
(196) It is also noted that anaerobic means of oxidative cleavage using photo-assistance with nitroarenes on polyaromatics within an electrochemical environment, as well as atom economy and self-sufficiency, enable green chemistry principles of synthesis. Aerobic chemistry can also be used for synthesis which may improve reaction times and yields.
Example 13: Application to Pharmaceuticals-Cortisol, Aldosterone Analogues
(197) The primer identified in
(198) Instead of a hydroxyl group as in cortisol, the relevant sidechain for the corresponding substituted chrysene is an oxalate derivative. Moreover, when coupled to form the heterodimer, the sidechain is extended with a phosphodiester bond, which is thereby available to interact with the unpaired ketone of thiamine or uracil during its formation process of DNA and RNA, respectively. Comparing the position of the hydroxyl group for cortisol in
(199) To relate the potential space of pharmaceutical equivalency between the primer structures and the catalyst, structural analysis demonstrated a correlation between the spatial positioning of the unpaired ketone and steroid hormones was one of efficacy in terms of the potential intermolecular bond strength shown in the examples of

Example 14: Application to Pharmaceuticals-Testosterone, Estrogenanalogs
(202) In addition to cortisol, the primer of
(203) Without wishing to be bound by theory, the bonding of testosterone to the androgen receptor could have a pocket available for an unaligned catalyst of which the sidechains at the 6,12 positions are available to alter the interaction of testosterone with the androgen receptor as proxy for interaction directly with the CG pairing. As with cortisol, in the case of testosterone, shown in
(204) In similar fashion to cortisol and to testosterone, the structural configurations of aldosterone and estrogen can be augmented at the 6,12 carbon positions with ethoxy alcohol sidechains to modulate the performance and the side-effects. Phosphorylation, and additional groups, along with stereochemistry in positioning the sidechains are available as tuning parameters to further amplify or attenuate the interaction of the sidechain and by proxy the nucleotide pairings. The end-groups may be adjusted as well in conjunction with the 6,12 sidechains. In a preferred embodiment, the four aromatic ring staggered structure of chrysene is deployed with oxalate alcohol side chains at the 3,9 positions.
Example 15: Application to Pharmaceuticals-Single Site Intercalation of Nucleic Acid Sequences
(205) The methodology of intercalating DNA sequences with molecules is used in chemotherapy, for example to reduce the progression of protein processing through transcription or replication to reduce cancerous cells out of control. Common materials used to achieve this result include doxorubicin and other anthracycline molecules. This approach uses a linear sequence of rings, generally four arranged in a linear fashion, to intercalate the DNA strand, while a bulky side chain locks the linear portion and halts strand processing. It is an effective approach, however, is generally indiscriminate and methods to reduce the side effects are sought.
(206) The methodology of synthesizing RNA and DNA described herein from primer cores (e.g., chrysene) which provide a natural method of intercalating and locking nucleic acid sequences. The synthesis of the RNA strand produces for each adenine in a sequence a covalently attached chrysene unit with head group, as shown in
Example 16: Application to Pharmaceuticals-Intercalation of Nucleic Acid Sequences
(207) The approach of single nucleobase intercalation can be extended to a targeted nucleic acid sequence in which a strand is deployed wherein each adenine is bound to an intercalating unit. In
(208) Sequential intercalation of which a targeted sequence is indicated in
(209) In addition to single-strand RNA, the approach is applicable to double-strand DNA, especially during periods of replication when the single-strand is exposed for more direct interaction with the adenine nucleobase and thymine. By targeting a nucleic acid sequence, rather than a single nucleotide, precision intercalation results and can be applied to target pathogens as well as cancerous cells.
Example 17: Application to Cell-Based Therapies-Encoded Cellular Membrane
(210) With the binding of the phospholipid structure to the adenine nucleobase at the carbon-2 position, the ribonucleic acid sequence for the first replication may attach into the phospholipid membrane. Thus, a spatial mapping between the cellular membrane and the initial instruction set is established. This relationship may then be applied to organize the initial condition of a physical cytoskeleton construct between the cellular membrane and the nucleic acid, permitting the communication of signals from the external environment into the genome. Consequently, the result is a spatially encoded cellular membrane that is correlated with its genomic contents. Applications include morphogenesis in which the spatial orientation of the cellular construct is set through a mapping with the replicating nucleic acid. This mapping is useful for cell-based therapies in which the genomic contents are combined within a programmable cellular enclosure to induce a targeted function.
Example 18: Random Generation of an Intercalated Sequence
(211) The formation of an intercalated sequence of 3,6,9,12-tetrasubstituted chrysene and 6,12-disubstituted chrysene is achievable through random self-assembly. Self-assembly may occur due to the differences in electrostatic potential of the outer rings of the chrysene base structure of the two molecules. Resonance structures of an ethoxy group substituted on the chrysene enable an electron donating characteristic of the outer rings of 3,6,9,12-tetrasubstituted chrysene relative to 6,12-disubstituted chrysene, which do not have sidechains on the outer rings. A flow chart illustrating this procedure is provided in
(212) Thus, the self-assembled pi-stacking of the structures will favor an intercalated format with the electropositive rings interleaved between electronegative rings, which is illustrated in
(213) After intercalation, phosphorylation of adjacent pairings and of the outer sidechains produces a heterodimeric system of structures. This heterodimeric system, after reaction, produce a nucleic acid sequence according to the codes provided herein. The electrostatic potential differences of the two molecules can be enhanced through selection of alternative sidechains, especially at the two carbon units, of which a double bond would further improve resonance effects on the outer rings. In addition, electron withdrawing groups can be added to the outer rings of disubstituted chrysene to aid in achieving an intercalated sequence, which afterwards can be removed. Because it is a self-assembled process, long random nucleotide sequences are possible, of which random genomes may be feasible. The process flow diagram for this procedure is presented in
Example 19: Directed Generation of an Intercalated Sequence
(214) In addition to a random orientation of the intercalated sequence to produce a resultant nucleic acid sequence, methods to induce a targeted sequence are available by linking the structures through the alcohol end groups. It is noted that the usual procedures applying phosphonamidites to construct oligonucleotides are available for designing methods of directed sequence construction. The advantages however of the planar carbon construct of the catalyst and substrate can find use for optimizing the directed sequence manufacturing mechanism, such as molecular constructs inert to the ultraviolet radiation of high-resolution photolithography.
(215) To arrange for the proper orientation and molecule, the 3,6,9,12-tetrasubstituted chrysene and 6,12-disubstituted chrysene are coupled into four configurations based on orientation, and then linked heterostructure are coupled in a sequence according to the specified codes of
Example 20: Directed A-T/T-A or G-C/C-G Synthesis Through Alignment or Unalignment of the Catalyst and Substrate Ring Structures
(216) The intermolecular spatial organization of the ring structure of the substrate to catalyst determines whether the configuration results in three-hydrogen bonds as in cytosine-guanine or in two-hydrogen bonds as in thymine-adenine, of which its code was presented in
