DETAILED DESCRIPTION

[0034] In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented herein. It will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the figures, can be arranged, substituted, combined, separated, and designed in a wide variety of different configurations, all of which are explicitly contemplated herein.

[0035] Generally, the present technology includes compounds for use as antimicrobials. In some aspects, the compounds can inhibit pathogenic microbes, such as bacteria, viruses, and fungi. The compounds can be used in methods for treating materials to be antimicrobial, and in methods of treating subjects infected with a microbe. The compounds can be prepared into various compositions, materials, or articles of manufacture for use as antimicrobials.

[0036] In some embodiments, the present technology includes compounds for use as selective antimicrobials. In some aspects, the compounds can selectively inhibit pathogenic microbes without significantly inhibiting commensal microbes. As used herein, a commensal microbe is considered to be any microbe that has commensalism, which is an association with another organism (e.g., subject), such as a human or other animals (e.g., mammals, birds, etc.) where the microbe receives a benefit for the association while the other organism may benefit and receives no harm from the association with the microbe. As used herein, a pathogenic microbe is considered to be any microbe that causes a disease state in a subject, such as a bacteria, virus, or fungus.

[0037] In some embodiments, the present invention relates to compounds that can be used as selective antimicrobials that selectively inhibit pathogenic microbes more than inhibiting commensal microbes. That is, the compounds can selectively inhibit pathogenic microbes in an amount or percent that is greater than commensal microbes are inhibited. While the commensal microbes can be inhibited by the compounds, such inhibition is significantly less than the inhibition of the pathogenic compounds. Thus, a greater degree of inhibition of the pathogenic microbes is achieved over inhibition of the commensal microbes.

[0038] In some embodiments, the selective antimicrobials can inhibit Trichophyton rubrum and Trichophyton mentagrophytes, which are the causative agents of athlete's foot and jock itch. As such, the pathogenic microbes can include Burkholderia cenocepacia, Trichophyton rubrum and Trichophyton mentagrophytes. However, it should be recognized that the pathogenic microbes may include other skin-disease causing microbes. The compounds have been shown to be selective antimicrobials against these pathologic microbes. It is thought that these compounds can also be selective against other pathogenic microbes for the inhibition thereof. Thus, a variety of pathogenic microbes that are fungi, bacteria, or viruses can be selectively inhibited over commensal microbes.

[0039] In some embodiments, the commensal microbes can include Malassezia furfur, Micrococcus sp., and Staphylococcus epidermidis. However, it should be recognized that the commensal microbes may include other microbes, such as those that live on the skin (e.g., skin commensal microbes). The compounds have been shown to have limited inhibition or effect on skin commensal microbes, such as those listed above. It is thought that these compounds can also be minimally active or have significantly reduced activity and inhibition against the skin commensal microbes, or other commensal microbes.

[0040] In some embodiments, the compounds described herein can be used as general antimicrobials. In some embodiments, the antimicrobial compounds can be used in any form and in any composition. The antimicrobial compounds can be included in pharmaceutically acceptable carriers and administered to a subject in need thereof. For example, the compounds can be included in a topical composition for use against topical pathogenic microbes, such as those that cause jock itch, athlete's foot, and others. The antimicrobial compounds can be included in various liquids, gels, pastes, emulsions, or other non-solid formats.

[0041] In some embodiments, the antimicrobials can be applied to a solid, whether particulate, porous, non-porous, or in any non-liquid, non-gel, or non-flowable format. The solids can be those that may come into contact with a skin of a subject, such as a human. The antimicrobials can be applied to a surface of a solid object, and/or be embedded, encapsulated, or otherwise included within the solid body. Some examples include fabrics, which may be used for various articles of manufacture, ranging from clothing (e.g., underwear, socks, pants, shorts, skirt, dress, shirt, blouse, jersey, hat, scarf, or other), bandages, tarps, floors, mats, carpets, towels, linens, furniture, mattress, cabinet, countertop, bathtub, sink, faucet, hot tub, toys, or the like, whether as a coating (e.g., in a paint, caulk, or coating) or within the material thereof. The antimicrobials may be generally added to baby products or children products to protect them from the pathogenic microbes. The antimicrobials may be applied to athletic products that are worn or used during a sport, such as to balls, bats, gloves, hats, uniforms, undergarments, shoes, or the like that come into contact with the skin of a subject. The antimicrobial may be applied to camping products, such as those worn or used that come into contact with the skin of a subject, such as tents, sleeping bags, walking sticks, ropes, bungee cords, or the like. Any article of manufacture can include the antimicrobial compound. Some examples that have antimicrobials include fabrics, which may be used for various articles of manufacture, ranging from clothing (e.g., underwear, socks, pants, shorts, skirt, dress, shirt, blouse, jersey, hat, scarf, or other), footwear (e.g., shoes, sandals, flip flops, boat shoes), bandages, surgical drapes, tarps, floors, mats, carpets, towels, linens, furniture, mattress, cabinet, countertop, bathtub, sink, faucet, hot tub, toys, or the like, whether as a coating (e.g., in a paint, caulk, or coating) or within the material thereof. Accordingly, the general antimicrobials can be applied to any liquid carrier or any solid member (e.g., to surface or within the material).

[0042] The antimicrobials may be generally added to baby products or children products to protect them from the pathogenic microbes while allowing the commensal microbes to be relatively unharmed (or significantly less harm). The selective antimicrobial may be applied to athletic products that are worn or used during a sport, such as to balls, bats, gloves, hats, uniforms, undergarments, shoes, or the like that come into contact with the skin of a subject. The selective antimicrobial may be applied to camping products, such as those worn or used that come into contact with the skin of a subject, such as tents, sleeping bags, walking sticks, ropes, bungee cords, or the like. Any article of manufacture can include the selective antimicrobial compound. Some examples that have selective antimicrobials include fabrics, which may be used for various articles of manufacture, ranging from clothing (e.g., underwear, socks, pants, shorts, skirt, dress, shirt, blouse, jersey, hat, scarf, or other), footwear (e.g., shoes, sandals, flip flops, boat shoes), bandages, surgical drapes, tarps, floors, mats, carpets, towels, linens, furniture, mattress, cabinet, countertop, bathtub, sink, faucet, hot tub, toys, or the like, whether as a coating (e.g., in a paint, caulk, or coating) or within the material thereof. Accordingly, the selective antimicrobials can be applied to any liquid carrier or any solid member (e.g., to surface or within the material).

[0043] In some embodiments, the antimicrobials can be used to treat or inhibit an active microbial infection or microbial colony on an object or in a liquid. That is, any antimicrobial can be applied used against microbes that are already present. However, the antimicrobials may also be used in a prophylactic therapy to provide the antimicrobial prior to there being a microbial infection or colony. Here, the antimicrobial can be administered to a person prior to being infected with the microbe in a prophylactic therapy. Also, the antimicrobial can be applied to objects so that the antimicrobial is present and functional when or if the object comes into contact with a microbe or otherwise inhibiting microbe colony formation on the object.

[0044] In some embodiments, the antimicrobials can be used as a treatment or prophylactic therapy for treating a biofilms or inhibiting or preventing formation of a biofilm. That is, the antimicrobial can be applied before, during, or after formation of a biofilm. As used herein, a biofilm is at least one type of microbe growing in a colony or group on a surface so as to form a film of the mirobe(s). Thus, the antimicrobials can inhibit formation or growth of biofilms.

[0045] In an aspect, the disclosure pertains to inhibitors of microbes, such as bacteria and fungi (antibacterials and antifungals) or viruses (e.g., antivirals) derived from a specific compound; pharmaceutical compositions comprising disclosed compounds and their derivatives; methods of treating growth of bacteria and/or fungi and/or viruses in or on mammals and objects.

Examples

[0205] A library of antimicrobial bacterial extracts were tested for antifungal activity against T. rubrum. The compounds provided herein emerged as the most potent. Targeted potency against pathogenic microbes was desired, and the compounds demonstrated significantly less potency against skin commensals M. furfur, S. epidermidis, and Micrococcus sp.. Subsequent purification using bioassay guided fractionation, HPLC, and LC-MS produced a potent and pure compound from 8 liters of CFD-110 extract. NMR was used to determine the molecular structure of CFD-110.

[0206] Generally, the compounds were synthesized using the method as previously described [Tetrahedron 71 (2015) 8885-8891]. Briefly, a mixture of indole (1 eq.), 4-hydroxythiophenol (1 eq.) and TBHP (1 eq.) were dissolved in MeCN at 60 C. in a flask, then iodine (0.2 eq.) was added. The reaction proceeded under an air atmosphere for 0.5-1.0 h until complete consumption of starting material as monitored by TLC. The reaction mixture was quenched by the addition of saturated aqueous Na.sub.2S.sub.2O.sub.3 and then extracted with EtOAc. The combined organic layer was concentrated under vacuum and the crude product was purified by prep-HPLC to produce compound CFD-110 (90% yield).

[0207] The Table 1 shows selectivity of CFD-174M, CFD-156I and CFD-156K against pathogens and skin commensals. Table 9 also shows the selectivity index (SI) for various compounds using B. subtilis MICs.

[0208] Table 2 shows the MBC (minimum bactericidal concentration) and MFC (minimum fungicidal concentration) of some of the antimicrobial compounds with Bacillus subtilis, Bacillus thuringiensis, Burkholderia cenocepacia, Burkholderia thailandensis, Candida glabrata, Trichophyton rubrum (Castellani Sabouraud), and Francisella tularensis subsp. Holarctica Strain LVSR NR-597.

[0209] Table 3 shows the MIC values for Staphylococcus aureus with VSSA (Vancomycin sensitive S. aureus), VRSA(Vancomycin resistant S. aureus), and MRSA (Methicillin resistant S. aureus).

[0210] Table 4 shows the MIC values for Bacillus subtilis strains.

[0211] Table 5 shows the MIC values for Bacillus thuringiensis strains.

[0212] Table 6 shows the MIC values for N. gonorrhoeae strains.

[0213] Table 7 shows the MIC values for Candida sp. with species C. glabrata strains and C. albicans strains.

[0214] Table 8 shows the MIC values for Francisella tularensis strains.

[0215] Table 10 shows an experimental protocol for studies for toxicity of the antimicrobial compounds in mice, where the dosing route, dose, dosing solution concentration, and dosing volume are described. The vehicle is 40% PEG300 solution in 0.9% NaCl. In Table 10, Compound 1 is Compound 174AU, Compound 2 is Compound 174AZ, and Compound 3 is Compound 174AI. The mice had an average weight of 22-23 grams and were 6-week-old Balb/c mice. Table 11 shows the result of the body weight over 7 days. As shown, these antimicrobial compounds did not have significant toxicity as evidenced by the weight staying consistent with small reductions. Thus, the compounds are useful for in vivo antimicrobial administration.

[0216] Table 12 shows the MIC data for the compounds 1000-1011 for Francisella tularensis (NR-577); Neisseria gonorrhoeae (WHO 901); and Neisseria gonorrhoeae (WHO 914); Neisseria gonorrhoeae (ATCC 49226).

[0217] Additionally, the antimicrobial compounds were analyzed for cytotoxicity. The compounds underwent cytotoxicity testing in the HepG2 liver cell line, and some of the best compounds based on selectivity index moved into the human HepaRG primary-like cell line for further cytotoxicity testing in more predictive cells with a natural drug metabolism enzyme (DME) profile. We utilized the standard MTT assay (Promega CellTiter 96) and GraphPad Prism 7 software to determine EC50 values for each analogue. Briefly, 20,000 HepG2 cells in 200 l of the ATCC recommended media were seeded in each well of a 96-well plate with a moisture barrier created in the outermost wells. The cells were allowed to attach overnight at 37 C., and then observed under phase contrast microscopy for proper morphological characteristics. If cells appeared healthy and attached, test compounds were added in 7 concentrations from 1-64 g/ml (n=3) from freshly prepared DMSO stock plates. The cells were incubated for 48 h and then stained with [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT)] and incubated at 37 C. for 4 h. Once incubations were complete, the spectrophotometric absorbance of the samples was measured at a wavelength of 595 nm. Acetaminophen EC50 served as the positive control and 1% DMSO samples are considered negative control and are used as reference for subsequent IC50 calculations. For the HepaRG assay, NoSpin HepaRG cells (Lonza, cat #NSHPRG) were thawed and plated with 20,000 cells per well. They were allowed to attach for 4 h (optimal DME profile per Lonza's testing) before dosing following the identical protocol as above. Table 9 below provides results for the EC50.

[0218] Additionally, an extensive study to explore the mechanism of action (MOA) has revealed that the series likely has 2 MOAs with varying degrees of each in different analogues. Fluorescence microscopy and radiolabeling studies have clearly shown cell wall synthesis inhibition as a MOA for the series of compounds with Compound No. 174I. Transcriptomic and metabolic studies have demonstrated branched chain amino acid biosynthesis inhibition as another MOA for 174I and 174M. The combination of cell wall synthesis inhibition and BCAA synthesis inhibition is the novel, dual mechanism behind our potent, broad-spectrum compounds. Multiple MOAs are ideal for combating AMR because the pathogen has to evolve 2 resistance mechanisms simultaneously to survive treatment with a dual MOA antimicrobial (e.g., antibiotic).

[0219] Cell wall permeability/disruption measured by SYTOX green fluorescence assay which emits only when able to enter the cell and bind DNA; FM 4-64 dye (red) which aggregates in disrupted cell walls. FIG. 1A shows SYTOX assay on S. aureus with analogue 174I. Concentrations are relative to the MIC, and a clear dose-dependent increase in permeability is demonstrated by the data. MEL is the positive control melittin which permeabilizes cells. FIG. 1B shows SYTOX assay with B. cenocepacia demonstrating cell permeabilization. FIG. 1C shows an image with FM 4-64 stained B. subtilis cells imaged with a fluorescence microscope. The arrows point to areas of aggregation and cell wall disruption seen in both analogue 174I and melittin treated cells only.

[0220] FIG. 2A-2B show the macromolecular synthesis assay dose-response curve demonstrating substantial cell wall synthesis inhibition with 174I (FIG. 2A) compared to vancomycin (FIG. 2B).

[0221] FIG. 2C shows the SYTOX assay indicates no permeabilization of HepG2 cells by up to 4MIC of analogues 174I and 174M. Additionally, data with HepG2 cells also indicates no cell membrane damage by the analogues by minimal staining in treated cells.

[0222] FIG. 3 shows a dose-dependent upregulation RNAseq data expressed in fold increase based on RNA sequencing experiments. The increase in these genes' expression suggests that when these analogues are given to the cells, a pathway is triggered which causes increased transcription of these genes. It could be that the compounds are inhibiting this pathway by binding a protein in the pathway and a feedback mechanism detects reduced pathway products or build-up of intermediates leading to increased expression to combat these effects. The branched chain amino acid synthesis pathway gene, ILVB is highly upregulated. ILVB's inhibition causes a build-up of 2-ketobutyrate which can be toxic at very high concentrations. We demonstrated a synergy between 174M and 2-ketobutyrate as shown in FIG. 3.

[0223] FIGS. 5A-5B show selectivity for inhibiting pathogenic microbes over commensal microbes on polyester fabric. FIG. 5A shows that Compound 156I selectively inhibits pathogens T. rubrum over commensal microbes R. mucosa and S. epidermidis. FIG. 5B shows that Compound 156K inhibits the pathogens T. rubrum and S. Aureus over commensal microbes R. mucosa and S. epidermidis

[0224] Additionally, an experiment was performed to determine synergistic effect of the compounds with 2-ketobutyrate compared to those of tetracycline with 2-ketobutyrate. Without ketobutyrate, the MIC of Compound 174M is 3.124 pg/mL and the MIC of tetracycline is 6.25. With 200 g/mL 2-ketobutyrate, the MIC of 174M dropped to 0.781 and with 800 g/mL 2-ketobutyrate, the MIC of 174M dropped to less than 0.39. However, the MIC for tetracycline did not change with either concentration of 2-ketobutyrate. Thus, at least Compound 174M provides a synergistic effect with 2-ketobutyrate. It is expected that the other compounds, especially those similar to Compound 174M, also can have a synergistic effect with 2-ketobutyrate.

Definitions

[0239] As used herein, the term infection is encompassed by the term colonization and includes disease associated colonization and/or undesirable colonization.

[0240] In some embodiments the treatment, mitigation, or prevention for Parkinson's disease in a subject in need thereof comprises physical removal or reduction (e.g. debridement) of the microbial infection.

[0241] The term administered, administering or administration includes routes of administration which allow the antimicrobial agents to perform their intended function(s) of preventing, mitigating, or treating disease in a subject. Examples of routes of administration include parenteral (e.g., subcutaneous, intramuscular, intraorbital, intracapsular, intraspinal, intrasternal, intravenous, intradermal, intraperitoneal, intraportal, intra-arterial, intrathecal, transmucosal, intra-articular, and intrapleural,), transdermal, topical, epidural, and mucosal injection or infusion, as well as oral, intranasal, inhalation, insufflation, pulmonary, and rectal administration Examples of preferred routes of administration which may be used include injection, topical, oral, intranasal, subcutaneous, intravenous, inhalation and transdermal.

[0242] In some embodiments, the antimicrobial agent is administered in combination with a pharmaceutically acceptable carrier. Examples of such carriers include those suitable for injection, topical, oral, intranasal, subcutaneous, intravenous, inhalation and/or transdermal administration.

[0243] When used herein, the term therapeutically effective amount or effective amount includes an amount of the therapeutic or treatment composition that provides a prophylactic or therapeutic benefit in the treatment, prevention, or management of a disease or a symptom of a disease. The therapeutically effective amount may treat a disease or condition, a symptom of disease, or a predisposition toward a disease, with the purpose to cure, heal, alleviate, relieve, alter, remedy, ameliorate, improve, or affect the disease, the symptoms of disease, or the predisposition toward disease. The term therapeutically effective amount or effective amount of the antimicrobial agent includes an amount of the antimicrobial agent that is sufficient in treating, mitigating, or preventing a microbial infection, such as jock itch or athlete's foot or other.

[0244] The dosage ranges for the administration are those that produce the desired effect. Generally, the dosage will vary with the age, weight, condition, and sex of the patient, and the extent of disease. A person of ordinary skill in the art, given the teachings of the present specification, may readily determine suitable dosage ranges.

[0245] As used herein, the term antimicrobial agent is any substance that has a significant biocidal and/or biostatic activity against a fungus for use in the treatment, mitigation, or prevention of disease. In some embodiments, the antimicrobial agent inhibits the growth of one or more microbial organisms in a subject receiving said agent. In some embodiments, the antimicrobial agent kills one or more microorganisms in a subject receiving said agent.

[0246] In some embodiments, the antimicrobial agent is a substance that has a biocidal and/or biostatic activity for microbes. In further embodiments, the antimicrobial agent is a substance that has a biocidal and/or biostatic activity that is relatively specific and selective for pathogenic microbes over commensal microbes.

[0247] By substituted as in substituted alkyl, substituted aryl, and the like, as alluded to in some of the definitions provided herein, is meant that in the alkyl, aryl, or other moiety, at least one hydrogen atom bound to a carbon (or other) atom is replaced with one or more non-hydrogen substituents.

[0248] In addition, the aforementioned functional groups may, if a particular group permits, be further substituted with one or more additional functional groups or with one or more hydrocarbyl moieties such as those specifically enumerated above. Analogously, the above-mentioned hydrocarbyl moieties may be further substituted with one or more functional groups or additional hydrocarbyl moieties such as those specifically enumerated.

[0249] When the term substituted appears prior to a list of possible substituted groups, it is intended that the term apply to every member of that group. For example, the phrase substituted alkyl, alkenyl, and aryl is to be interpreted as substituted alkyl, substituted alkenyl, and substituted aryl. Analogously, when the term heteroatom-containing appears prior to a list of possible heteroatom-containing groups, it is intended that the term apply to every member of that group. For example, the phrase heteroatom-containing alkyl, alkenyl, and aryl is to be interpreted as heteroatom-containing alkyl, heteroatom-containing alkenyl, and heteroatom-containing aryl.

[0250] As used herein, optionally substituted indicates that a chemical structure may be optionally substituted with a substituent group, such as defined herein. That is, when a chemical structure includes an atom that is optionally substituted, the atom may or may not include the optional substituent group, and thereby the chemical structure may be considered to be substituted when having a substituent on the atom or unsubstituted when omitting a substituent from the atom. A substituted group, referred to as a substituent or substituent group, can be coupled (e.g., covalently) to a previously unsubstituted parent structure, wherein one or more hydrogen atoms (or other substituent groups) on the parent structure have been independently replaced by one or more of the substituents. The substituent is a chemical moiety that is added to a base chemical structure, such as a chemical scaffold. As such, a substituted chemical structure may have one or more substituent groups on the parent structure, such as by each substituent group being coupled to an atom of the parent structure. The substituent groups that can be coupled to the parent structure can be any possible substituent group. In examples of the present technology, the substituent groups (e.g., R groups) can be independently selected from an alkyl, O-alkyl (e.g. OCH.sub.3, OC.sub.2H.sub.5, OC.sub.3H.sub.7, OC.sub.4H.sub.9, etc.), S-alkyl (e.g., SCH.sub.3, SC.sub.2H.sub.5, SC.sub.3H.sub.7, SC.sub.4H.sub.9, etc.), NRR, OH, SH, CN, NO.sub.2, or a halogen, wherein R and R are independently H or an optionally substituted alkyl. Wherever a substituent is described as optionally substituted, that substituent can also be optionally substituted with the above substituents.

[0251] The term amino refers to the overall charged or net uncharged chemical group, where the R group can be a substituent, such as the substituents described herein:

[0264] All other chemistry terms are defined as known in the art.

[0265] One skilled in the art will appreciate that, for this and other processes and methods disclosed herein, the functions performed in the processes and methods may be implemented in differing order. Furthermore, the outlined steps and operations are only provided as examples, and some of the steps and operations may be optional, combined into fewer steps and operations, or expanded into additional steps and operations without detracting from the essence of the disclosed embodiments.

[0266] The present disclosure is not to be limited in terms of the particular embodiments described in this application, which are intended as illustrations of various aspects. Many modifications and variations can be made without departing from its spirit and scope, as will be apparent to those skilled in the art. Functionally equivalent methods and apparatuses within the scope of the disclosure, in addition to those enumerated herein, will be apparent to those skilled in the art from the foregoing descriptions. Such modifications and variations are intended to fall within the scope of the appended claims. The present disclosure is to be limited only by the terms of the appended claims, along with the full scope of equivalents to which such claims are entitled. It is to be understood that this disclosure is not limited to particular methods, reagents, compounds compositions or biological systems, which can, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to be limiting.

[0267] With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.

[0268] It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as open terms (e.g., the term including should be interpreted as including but not limited to, the term having should be interpreted as having at least, the term includes should be interpreted as includes but is not limited to, etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases at least one and one or more to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles a or an limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases one or more or at least one and indefinite articles such as a or an (e.g., a and/or an should be interpreted to mean at least one or one or more); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should be interpreted to mean at least the recited number (e.g., the bare recitation of two recitations, without other modifiers, means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to at least one of A, B, and C, etc. is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., a system having at least one of A, B, and C would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to at least one of A, B, or C, etc. is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., a system having at least one of A, B, or C would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase A or B will be understood to include the possibilities of A or B or A and B.

[0269] In addition, where features or aspects of the disclosure are described in terms of Markush groups, those skilled in the art will recognize that the disclosure is also thereby described in terms of any individual member or subgroup of members of the Markush group.

[0270] As will be understood by one skilled in the art, for any and all purposes, such as in terms of providing a written description, all ranges disclosed herein also encompass any and all possible subranges and combinations of subranges thereof. Any listed range can be easily recognized as sufficiently describing and enabling the same range being broken down into at least equal halves, thirds, quarters, fifths, tenths, etc. As a non-limiting example, each range discussed herein can be readily broken down into a lower third, middle third and upper third, etc. As will also be understood by one skilled in the art all language such as up to, at least, and the like include the number recited and refer to ranges which can be subsequently broken down into subranges as discussed above. Finally, as will be understood by one skilled in the art, a range includes each individual member. Thus, for example, a group having 1-3 cells refers to groups having 1, 2, or 3 cells. Similarly, a group having 1-5 cells refers to groups having 1, 2, 3, 4, or 5 cells, and so forth.

[0271] From the foregoing, it will be appreciated that various embodiments of the present disclosure have been described herein for purposes of illustration, and that various modifications may be made without departing from the scope and spirit of the present disclosure. Accordingly, the various embodiments disclosed herein are not intended to be limiting, with the true scope and spirit being indicated by the following claims.

[0272] All references recited herein are incorporated herein by specific reference in their entirety. Specific reference is made to U.S. Ser. No. 16/904,364 filed Jun. 17, 2020; and U.S. No. 63/517,301 filed Aug. 2, 2023.
