Description
DETAILED DESCRIPTION
Definitions
[0127] As used in the present specification, the following words and phrases are generally intended to have the meanings as set forth below, except to the extent that the context in which they are used indicates otherwise.
[0128] Throughout this application, unless the context indicates otherwise, references to a compound of Formula (I) includes all subgroups of Formula (I) defined herein, including all substructures, subgenera, preferences, embodiments, examples and particular compounds defined and/or described herein. References to a compound of Formula (I) and subgroups thereof include ionic forms, polymorphs, pseudopolymorphs, amorphous forms, solvates, co-crystals, chelates, isomers, tautomers, oxides (e.g., N-oxides, S-oxides), esters, prodrugs, isotopes and/or protected forms thereof. In some embodiments, references to a compound of Formula (I) and subgroups thereof include polymorphs, solvates, co-crystals, isomers, tautomers and/or oxides thereof. In some embodiments, references to a compound of Formula (I) and subgroups thereof include polymorphs, solvates, and/or co-crystals thereof. In some embodiments, references to a compound of Formula (I) and subgroups thereof include isomers, tautomers and/or oxides thereof. In some embodiments, references to a compound of Formula (I) and subgroups thereof, include solvates thereof. Similarly, the term salts includes solvates of salts of compounds.
[0129] Alkyl encompasses straight and branched carbon chains having the indicated number of carbon atoms, for example, from 1 to 20 carbon atoms, or 1 to 8 carbon atoms, or 1 to 6 carbon atoms. For example, C.sub.1-6 alkyl encompasses both straight and branched chain alkyl of from 1 to 6 carbon atoms. When an alkyl residue having a specific number of carbons is named, all branched and straight chain versions having that number of carbons are intended to be encompassed; thus, for example, propyl includes n-propyl and isopropyl; and butyl includes n-butyl, sec-butyl, isobutyl and t-butyl. Examples of alkyl groups include, but are not limited to, methyl, ethyl, propyl, isopropyl, n-butyl, sec-butyl, tert-butyl, pentyl, 2-pentyl, 3-pentyl, isopentyl, neopentyl, hexyl, 2-hexyl, 3-hexyl, and 3-methylpentyl.
[0130] As used herein, the term alkylene refers to divalent alkyl group as defined herein above having 1 to 20 carbon atoms. Unless otherwise provided, alkylene refers to moieties having 1 to 20 carbon atoms, 1 to 16 carbon atoms, 1 to 10 carbon atoms, 1 to 7 carbon atoms, or 1 to 4 carbon atoms. Alkylene groups include, but are not limited to, methylene, ethylene, n-propylene, iso-propylene, n-butylene, sec-butylene, iso-butylene, tert-butylene, n-pentylene, isopentylene, neopentylene, n-hexylene, 3-methylhexylene, 2,2-dimethylpentylene, 2,3-dimethylpentylene, n-heptylene, n-octylene, n-nonylene, and n-decylene.
[0131] When a range of values is given (e.g., C.sub.1-6 alkyl), each value within the range as well as all intervening ranges are included. For example, C.sub.1-6 alkyl includes C.sub.1, C.sub.2, C.sub.3, C.sub.4, C.sub.5, C.sub.6, C.sub.1-6, C.sub.2-6, C.sub.3-6, C.sub.4-6, C.sub.5-6, C.sub.1-5, C.sub.2-5, C.sub.3-5, C.sub.4-5, C.sub.1-4, C.sub.2-4, C.sub.3-4, C.sub.1-3, C.sub.2-3, and C.sub.1-2 alkyl.
[0132] Cycloalkyl indicates a non-aromatic, fully saturated carbocyclic ring having the indicated number of carbon atoms, for example, 3 to 10, or 3 to 8, or 3 to 6 ring carbon atoms. Cycloalkyl groups may be monocyclic or polycyclic (e.g., bicyclic, tricyclic), spiro, branched, and/or bridged. Examples of cycloalkyl groups include cyclopropyl, cyclobutyl, cyclopentyl, and cyclohexyl, as well as bridged, caged, and spirocyclic ring groups (e.g., norbornane, bicyclo[2.2.2]octane, spiro[3.3]heptane). In addition, one ring of a polycyclic cycloalkyl group may be aromatic, provided the polycyclic cycloalkyl group is bound to the parent structure via a non-aromatic carbon. For example, a 1,2,3,4-tetrahydronaphthalen-1-yl group (wherein the moiety is bound to the parent structure via a non-aromatic carbon atom) is a cycloalkyl group, while 1,2,3,4-tetrahydronaphthalen-5-yl (wherein the moiety is bound to the parent structure via an aromatic carbon atom) is not considered a cycloalkyl group. Examples of polycyclic cycloalkyl groups consisting of a cycloalkyl group fused to an aromatic ring are described below.
[0133] Cycloalkenyl indicates a non-aromatic carbocyclic ring, containing the indicated number of carbon atoms (e.g., 3 to 10, or 3 to 8, or 3 to 6 ring carbon atoms) and at least one carbon-carbon double bond. Cycloalkenyl groups may be monocyclic or polycyclic (e.g., bicyclic, tricyclic). Examples of cycloalkenyl groups include cyclopropenyl, cyclobutenyl, cyclopentenyl, cyclopentadienyl, and cyclohexenyl, as well as bridged and caged ring groups (e.g., bicyclo[2.2.2]octene). In addition, one ring of a polycyclic cycloalkenyl group may be aromatic, provided the polycyclic alkenyl group is bound to the parent structure via a non-aromatic carbon atom. For example, inden-1-yl (wherein the moiety is bound to the parent structure via a non-aromatic carbon atom) is considered a cycloalkenyl group, while inden-4-yl (wherein the moiety is bound to the parent structure via an aromatic carbon atom) is not considered a cycloalkenyl group. Examples of polycyclic cycloalkenyl groups consisting of a cycloalkenyl group fused to an aromatic ring are described below.
[0134] Aryl indicates an aromatic carbocyclic ring having the indicated number of carbon atoms, for example, 6 to 12 or 6 to 10 carbon atoms. Aryl groups may be monocyclic or polycyclic (e.g., bicyclic, tricyclic). In some instances, both rings of a polycyclic aryl group are aromatic (e.g., naphthyl). In other instances, polycyclic aryl groups may include a non-aromatic ring fused to an aromatic ring, provided the polycyclic aryl group is bound to the parent structure via an atom in the aromatic ring. Thus, a 1,2,3,4-tetrahydronaphthalen-5-yl group (wherein the moiety is bound to the parent structure via an aromatic carbon atom) is considered an aryl group, while 1,2,3,4-tetrahydronaphthalen-1-yl (wherein the moiety is bound to the parent structure via a non-aromatic carbon atom) is not considered an aryl group. Similarly, a 1,2,3,4-tetrahydroquinolin-8-yl group (wherein the moiety is bound to the parent structure via an aromatic carbon atom) is considered an aryl group, while 1,2,3,4-tetrahydroquinolin-1-yl group (wherein the moiety is bound to the parent structure via a non-aromatic nitrogen atom) is not considered an aryl group. However, the term aryl does not encompass or overlap with heteroaryl, as defined herein, regardless of the point of attachment (e.g., both quinolin-5-yl and quinolin-2-yl are heteroaryl groups).

Additional examples of aryl groups comprising an aromatic carbon ring fused to a non-aromatic ring are described below.
[0135] Heteroaryl indicates an aromatic ring containing the indicated number of atoms (e.g., 5 to 12, or 5 to 10 membered heteroaryl) made up of one or more heteroatoms (e.g., 1, 2, 3 or 4 heteroatoms) selected from N, O and S and with the remaining ring atoms being carbon. Heteroaryl groups do not contain adjacent S and O atoms. In some embodiments, the total number of S and O atoms in the heteroaryl group is not more than 2. In some embodiments, the total number of S and O atoms in the heteroaryl group is not more than 1. Unless otherwise indicated, heteroaryl groups may be bound to the parent structure by a carbon or nitrogen atom, as valency permits.

[0138] In other instances, polycyclic heteroaryl groups may include a non-aromatic ring (e.g., cycloalkyl, cycloalkenyl, heterocycloalkyl, heterocycloalkenyl) fused to a heteroaryl ring, provided the polycyclic heteroaryl group is bound to the parent structure via an atom in the aromatic ring. For example, a 4,5,6,7-tetrahydrobenzo[d]thiazol-2-yl group (wherein the moiety is bound to the parent structure via an aromatic carbon atom) is considered a heteroaryl group, while 4,5,6,7-tetrahydrobenzo[d]thiazol-5-yl (wherein the moiety is bound to the parent structure via a non-aromatic carbon atom) is not considered a heteroaryl group. Examples of polycyclic heteroaryl groups consisting of a heteroaryl ring fused to a non-aromatic ring are described below.
[0139] Heterocycloalkyl indicates a non-aromatic, fully saturated ring having the indicated number of atoms (e.g., 3 to 10, or 3 to 7, membered heterocycloalkyl) made up of one or more heteroatoms (e.g., 1, 2, 3 or 4 heteroatoms) selected from N, O and S and with the remaining ring atoms being carbon. Heterocycloalkyl groups may be monocyclic or polycyclic (e.g., bicyclic, tricyclic), spiro, branched, and/or bridged. Examples of heterocycloalkyl groups include oxiranyl, aziridinyl, azetidinyl, pyrrolidinyl, imidazolidinyl, pyrazolidinyl, piperidinyl, piperazinyl, morpholinyl and thiomorpholinyl.

In addition, one ring of a polycyclic heterocycloalkyl group may be aromatic (e.g., aryl or heteroaryl), provided the polycyclic heterocycloalkyl group is bound to the parent structure via a non-aromatic carbon or nitrogen atom. For example, a 1,2,3,4-tetrahydroquinolin-1-yl group (wherein the moiety is bound to the parent structure via a non-aromatic nitrogen atom) is considered a heterocycloalkyl group, while 1,2,3,4-tetrahydroquinolin-8-yl group (wherein the moiety is bound to the parent structure via an aromatic carbon atom) is not considered a heterocycloalkyl group. Examples of polycyclic heterocycloalkyl groups consisting of a heterocycloalkyl group fused to an aromatic ring are described below.
[0140] Heterocycloalkenyl indicates a non-aromatic ring having the indicated number of atoms (e.g., 3 to 10, or 3 to 7, membered heterocycloalkyl) made up of one or more heteroatoms (e.g., 1, 2, 3 or 4 heteroatoms) selected from N, O and S and with the remaining ring atoms being carbon, and at least one double bond derived by the removal of one molecule of hydrogen from adjacent carbon atoms, adjacent nitrogen atoms, or adjacent carbon and nitrogen atoms of the corresponding heterocycloalkyl.

In addition, one ring of a polycyclic heterocycloalkenyl group may be aromatic (e.g., aryl or heteroaryl), provided the polycyclic heterocycloalkenyl group is bound to the parent structure via a non-aromatic carbon or nitrogen atom. For example, a 1,2-dihydroquinolin-1-yl group (wherein the moiety is bound to the parent structure via a non-aromatic nitrogen atom) is considered a heterocycloalkenyl group, while 1,2-dihydroquinolin-8-yl group (wherein the moiety is bound to the parent structure via an aromatic carbon atom) is not considered a heterocycloalkenyl group. Examples of polycyclic heterocycloalkenyl groups consisting of a heterocycloalkenyl group fused to an aromatic ring are described below.

As discussed herein, whether each ring is considered an aryl, heteroaryl, cycloalkyl, cycloalkenyl, heterocycloalkyl or heterocycloalkenyl group is determined by the atom through which the moiety is bound to the parent structure.
[0142] Halogen or halo refers to fluorine, chlorine, bromine or iodine.
[0143] Unless otherwise indicated, compounds disclosed and/or described herein include all possible enantiomers, diastereomers, meso isomers and other stereoisomeric forms, including racemic mixtures, optically pure forms and intermediate mixtures thereof. Enantiomers, diastereomers, meso isomers and other stereoisomeric forms can be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques.

When the compounds described herein contain moieties capable of tautomerization, and unless specified otherwise, it is intended that the compounds include all possible tautomers.
[0144] Protecting group has the meaning conventionally associated with it in organic synthesis, i.e., a group that selectively blocks one or more reactive sites in a multifunctional compound such that a chemical reaction can be carried out selectively on another unprotected reactive site, and such that the group can readily be removed after the selective reaction is complete. A variety of protecting groups are disclosed, for example, in T.H. Greene and P. G. M. Wuts, Protective Groups in Organic Synthesis, Third Edition, John Wiley & Sons, New York (1999). For example, a hydroxy protected form contains at least one hydroxy group protected with a hydroxy protecting group. Likewise, amines and other reactive groups may similarly be protected.
[0145] The term pharmaceutically acceptable salt refers to a salt of any of the compounds herein which are known to be non-toxic and are commonly used in the pharmaceutical literature. In some embodiments, the pharmaceutically acceptable salt of a compound retains the biological effectiveness of the compounds described herein and are not biologically or otherwise undesirable. Examples of pharmaceutically acceptable salts can be found in Berge et al., Pharmaceutical Salts, J. Pharmaceutical Sciences, January 1977, 66(1), 1-19.

the indicated substituent can be at any valency-allowed position, including the NH, as in
##STR00009##
Furthermore, when a bicyclic group with variable substitution is depicted, the indicated substituent can be at any valency-allowed position at either ring or at both rings. For instance, the R.sup.B substituent of
##STR00010##
can be at either the cyclopentyl or the cyclopropyl component of the fused system, or it can be at both the cyclopentyl and the cyclopropyl components of the fused system. When a group or moiety bears more than one substituent, it is understood that the substituents may be the same or different from one another. In some embodiments, a substituted group or moiety bears from one to five substituents. In some embodiments, a substituted group or moiety bears one substituent. In some embodiments, a substituted group or moiety bears two substituents. In some embodiments, a substituted group or moiety bears three substituents. In some embodiments, a substituted group or moiety bears four substituents. In some embodiments, a substituted group or moiety bears five substituents.
[0150] By optional or optionally is meant that the subsequently described event or circumstance may or may not occur, and that the description includes instances where the event or circumstance occurs and instances in which it does not. For example, optionally substituted alkyl encompasses both alkyl and substituted alkyl as defined herein. It will be understood by those skilled in the art, with respect to any group containing one or more substituents, that such groups are not intended to introduce any substitution or substitution patterns that are sterically impractical, synthetically non-feasible, and/or inherently unstable. It will also be understood that where a group or moiety is optionally substituted, the disclosure includes both embodiments in which the group or moiety is substituted and embodiments in which the group or moiety is unsubstituted.
[0151] The compounds disclosed and/or described herein can be enriched isotopic forms, e.g., enriched in the content of .sup.2H, .sup.3H, .sup.11C, .sup.13C and/or .sup.14C. In one embodiment, the compound contains at least one deuterium atom. Such deuterated forms can be made, for example, by the procedure described in U.S. Pat. Nos. 5,846,514 and 6,334,997. Such deuterated compounds may improve the efficacy and increase the duration of action of compounds disclosed and/or described herein. Deuterium substituted compounds can be synthesized using various methods, such as those described in: Dean, D., Recent Advances in the Synthesis and Applications of Radiolabeled Compounds for Drug Discovery and Development, Curr. Pharm. Des., 2000; 6(10); Kabalka, G. et al., The Synthesis of Radiolabeled Compounds via Organometallic Intermediates, Tetrahedron, 1989, 45(21), 6601-21; and Evans, E., Synthesis of radiolabeled compounds, J.

Supplementary active ingredients can also be incorporated into the pharmaceutical compositions.
[0153] The terms patient, individual, and subject refer to an animal, such as a mammal, bird, or fish. In some embodiments, the patient or subject is a mammal. Mammals include, for example, mice, rats, dogs, cats, pigs, sheep, horses, cows and humans. In some embodiments, the patient or subject is a human, for example a human that has been or will be the object of treatment, observation or experiment. The compounds, compositions and methods described herein can be useful in both human therapy and veterinary applications.
[0154] As used herein, the term therapeutic refers to the ability to modulate nicotinamide phosphoribosyltransferase (NAMPT). As used herein, modulation refers to a change in activity as a direct or indirect response to the presence of a chemical entity as described herein, relative to the activity of in the absence of the chemical entity. The change may be an increase in activity or a decrease in activity, and may be due to the direct interaction of the chemical entity with the target or due to the interaction of the chemical entity with one or more other factors that in turn affect the target's activity. For example, the presence of the chemical entity may, for example, increase or decrease the target activity by directly binding to the target, by causing (directly or indirectly) another factor to increase or decrease the target activity, or by (directly or indirectly) increasing or decreasing the amount of target present in the cell or organism.
[0155] The term therapeutically effective amount or effective amount refers to that amount of a compound disclosed and/or described herein that is sufficient to affect treatment, as defined herein, when administered to a patient in need of such treatment. A therapeutically effective amount of a compound may be an amount sufficient to treat a disease responsive to modulation of nicotinamide phosphoribosyltransferase (NAMPT). The therapeutically effective amount will vary depending upon, for example, the subject and disease condition being treated, the weight and age of the subject, the severity of the disease condition, the particular compound, the dosing regimen to be followed, timing of administration, the manner of administration, all of which can readily be determined by one of ordinary skill in the art. The therapeutically effective amount may be ascertained experimentally, for example by assaying blood concentration of the chemical entity, or theoretically, by calculating bioavailability.
[0156] Treatment (and related terms, such as treat, treated, treating) includes one or more of: slowing or arresting the development of clinical symptoms of a disease or disorder; and/or relieving a disease or disorder (i.e., causing relief from or regression of clinical symptoms). The term covers both complete and partial reduction or prevention of the condition or disorder, and complete or partial reduction of clinical symptoms of a disease or disorder. Thus, compounds described and/or disclosed herein may prevent an existing disease or disorder from worsening, assist in the management of the disease or disorder, or reduce or eliminate the disease or disorder.

[0497] There are numerous conditions in which small molecule-mediated stimulation of NAMPT activity that boosts NAD+ levels would potentially be clinically beneficial (Str?mland et al., Biochem Soc Trans. 2019, 47(1):119-130; Ralto et al., Nat Rev Nephrol. 2019; Fang et al., Trends Mol Med. 2017, 23(10):899-916; Yoshino et al., Cell Metab. 2011,14(4):528-36; Yang and Sauve, Biochim Biophys Acta. 2016, 1864:1787-1800; Verdin, Science. 2015, 350(6265):1208-13). These conditions include, but are not limited to, cardiac diseases, chemotherapy induced tissue damage, renal diseases, metabolic diseases, muscular diseases, neurological diseases and injuries, diseases caused by impaired stem cell function, and DNA damage and primary mitochondrial disorders. In some embodiments, the disease or condition mediated by NAMPT activity is a cardiac disease, chemotherapy induced tissue damage, a renal disease, a metabolic disease, a muscular disease, a neurological disease or injury, a disease caused by impaired stem cell function, or DNA damage and primary mitochondrial disorder.
[0498] Cardiac diseases. In various preclinical models of heart failure NAD as well as NAMPT levels are decreased. In these models, cardiac function can be rescued, either by restoring NAD via oral supplementation or overexpression of NAMPT (Diguet et al, Circulation. 2018, 137:2256-2273; Zheng et al., Clin Sci (Lond). 2019, 133(13):1505-1521; Smyrnias et al., J Am Coll Cardiol. 2019, 73(14):1795-1806). Thus, increasing the catalytic efficiency of NAMPT with a small molecule activator to compensate for the decreased protein levels is a promising strategy to treat various forms of heart failure.
[0499] Chemotherapy induced tissue damage. Use of chemotherapy regimens frequently is limited by toxicity to healthy tissues and severe oxidative stress is thought to play a major role. NAD boosting has been shown to trigger a strong antioxidant response. Therefore, NAMPT activators are considered broadly useful in various settings of chemotherapy to prevent reversible and irreversible secondary pathologies. Examples are anthracycline and trastuzumab cardiotoxicity, cisplatin induced kidney injury, peripheral neuropathies induced by cisplatin, paclitaxel, vincristine and other agents. Neuroprotection by NAMPT activation is also useful in treating/preventing chemotherapy associated cognitive (chemo brain), which is caused by destruction of healthy nerve tissue, both during active treatment and long after treatment has been halted. For instance, see Zheng et al., Clin Sci (Lond). 2019, 133(13):1505-1521.
[0500] Renal diseases. Renal diseases are highly prevalent and an area of urgent unmet medical need. In approximately 3% of hospitalized patients, acute kidney injury (AKI) is diagnosed. A subset of patients will progress to chronic kidney disease that may require long-term dialysis or kidney transplantation. A key feature of kidney dysfunction is a decrease in the activities of SIRT1 and SIRT3, characterized by a reduction of the sirtuin substrate NAD, primarily due to impairment of de novo NAD+ synthesis. NAMPT is robustly expressed during kidney injury, thus small molecule activation with NAMPT is considered an effective measure to prevent AKI. Similarly, kidney mesangial cell hypertrophy exhibits depletion of NAD+, and restoration of intracellular NAD+ levels is considered efficacious. For instance, see Poyan Mehr et al., Nat Med. 2018, September; 24(9): 1351-9.
[0501] Metabolic disease. NAD+ boosting improves insulin sensitivity, dyslipidemia, mitochondrial function in metabolic disease and protects from/improves non-alcoholic and alcoholic steatohepatitis in preclinical models. More than 3 million people per year in the U.S. alone are diagnosed with non-alcoholic steatohepatitis and it is one of the leading causes of liver transplantation. See Guarino and Dufour, Metabolites. 2019 Sep. 10; 9(9), pii: E180; Yoshino et al., Cell Metab. 2011, 14(4):528-36.
[0502] Muscular diseases. Preclinical data has suggested that NAD+ boosting strategies could alleviate skeletal muscle dysfunction in a number of conditions, including Duchenne's muscular dystrophy, and age-related sarcopenia. See Zhang et al., Clin Sci (Lond). 2019, 133(13):1505-1521; Mohamed et al., Aging (Albany NY). 2014, 6(10):820-34; Ryu et al., Sci Transl Med. 2016, 8(361):361ra139.
[0503] Neurological diseases and injuries. Repletion of NAD by means of NAMPT activation is neuroprotective and of therapeutic benefit in a wide range of preclinical models of neurological diseases and injuries, including age-related cognitive decline, glaucoma, ischemic stroke, and ALS. See Johnson et al., NPJ Aging Mech Dis. 2018, 4:10; Harlan et al., J Biol Chem. 2016, 291(20):10836-46; Zhao et al., Stroke. 2015, July; 46(7):1966-74; Williams et al., Front Neurosci. 2017 Apr. 25; 11:232; Blacher et al Nature, 2019, volume 572, 474-480; Harlan et al., 2020. Experimental Neurology 327:113219.
[0504] Diseases caused by impaired stem cell function. NAD boosting promotes stem cell activation and hematopoiesis and is useful in accelerating the expansion of stem cell populations following a stem cell transplant. See Pi et al., Aging (Albany NY). 2019, 11(11):3505-3522.
[0505] DNA damage disorders and primary mitochondrial disorders. NAMPT activators will also be useful in the treatment of DNA damage disorders which are associated with an accelerated aging phenotype, such as Xeroderma pigmentosum, Cockayne syndrome, and Ataxia telangiectasia. Similarly, there are several primary mitochondrial disorders with shared symptoms and manifestations for which NAD boosting via NAMPT activation may be a suitable therapeutic intervention. See Fang et al, Cell. 2014, 157(4):882-896; Khan et al, EMBO Mol Med. 2014, June; 6(6):721-31; Cerutti et al., Cell Metab. 2014, 19(6):1042-9.

General Synthetic Methods
[0632] Compounds of Formula (I), or any variation or embodiment thereof, or a salt of any of the foregoing, will now be described by reference to illustrative synthetic schemes for their general preparation below and the specific examples that follow. Artisans will recognize that, to obtain the various compounds herein, starting materials may be suitably selected so that the ultimately desired substituents will be carried through the reaction scheme with or without protection as appropriate to yield the desired product. Alternatively, it may be necessary or desirable to employ, in the place of the ultimately desired substituent, a suitable group that may be carried through the reaction scheme and replaced as appropriate with the desired substituent. In addition, one of skill in the art will recognize that protecting groups may be used to protect certain functional groups (amino, carboxy, or side chain groups) from reaction conditions, and that such groups are removed under standard conditions when appropriate. Unless otherwise specified, the variables are as defined above in reference to Formula (I).
[0633] Where it is desired to obtain a particular enantiomer of a compound, this may be accomplished from a corresponding mixture of enantiomers using any suitable conventional procedure for separating or resolving enantiomers. Thus, for example, diastereomeric derivatives may be produced by reaction of a mixture of enantiomers, e.g. a racemate, and an appropriate chiral compound. The diastereomers may then be separated by any convenient means, for example by crystallization and the desired enantiomer recovered. In another resolution process, a racemate may be separated using chiral High Performance Liquid Chromatography. Alternatively, if desired a particular enantiomer may be obtained by using an appropriate chiral intermediate in one of the processes described.
[0634] Chromatography, recrystallization and other conventional separation procedures may also be used with intermediates or final products where it is desired to obtain a particular isomer of a compound or to otherwise purify a product of a reaction.

NMN Fluorescence Biochemical Assay
Human Recombinant Enzyme Assay
[0789] Compounds described herein were assayed for their ability to stimulate the synthesis of nicotinamide mononucleotide (NMN) by the enzyme NAMPT. The human recombinant enzyme assay measures the activation of the enzyme activity by compounds using recombinant enzyme and substrates in a buffered cell-free system. The assay conditions closely mimic cellular environments. Dose responses were measured using an assay to detect the formation of nicotinamide mono-nucleotide. All experiments were performed in the 384-well format. Generally, 0.5 ?L of DMSO containing varying concentrations of the test compound was mixed with 10 ?L of the enzyme reagent solution. Enzyme reactions were initiated with the addition of L of a solution containing the substrates. The final assay conditions were as follows: 6 nM human NAMPT, 2.5 mM ATP, 20 ?M PRPP and 150 ?M nicotinamide in 50 mM HEPES, pH 7.2, 1 mM DTT, 1 mM CHAPS 50 mM NaCl, 100 mM MgCl.sub.2. Following an incubation of 60 min at ambient temperature, 10 ?L of 20% acetophenone in DMSO was added, followed by 10 ?L of 2 M KOH and 40 ?L of formic acid. The plates were read for fluorescence (Excitation/Emission=355 nm/460 nm) using an EnVision plate reader after 40 mins of incubation at ambient temperature. The potency measurements for compounds are quantified and represented as AC.sub.1.4 (the concentration of compounds that generates 40% higher activity over basal) and EC.sub.50 (concentration of the compound that gives half-maximal activation). Table A shows the AC.sub.1.4 and EC.sub.50 data and for the tested compounds.

MDR1-MDCK Bidirectional Permeability Assay
[0790] The blood-brain barrier (BBB) is composed of brain capillary endothelial cells, which are characterized by highly developed tight junctions. The BBB plays a key role in the brain penetration of drugs and is an obstacle to the discovery of drugs where the drug target is in the central nervous system (CNS). P-Glycoproteins (P-gp, MDR1) are highly expressed at the BBB and serve to actively efflux drugs out of the brain and therefore may limit brain penetration of drugs to the desired target. A bidirectional permeability assay using Madin Darby canine kidney cells expressing multi-drug resistance gene 1 (MDCK-MDR1) is routinely used to evaluate discovery compounds' BBB permeability and drug efflux toward the advancement of discovery compounds with brain penetration.
[0791] MDCK-MDR1 Cells (NIH cell line) were obtained from the National Institutes of Health. MDCK-MDR1 cells were diluted to 1.56 million cells/mL (NIH) with culture medium and 50 ?L of cell suspension were dispensed into the filter wells of a 96-well HTS Transwell plate. Cells were cultivated for 4-8 days in a cell culture incubator at 37? C., 5% CO.sub.2, 95% relative humidity. Cell culture medium was replaced every other day, beginning no later than 24 hours after the initial plating. The permeability assay used buffer was Hanks' balanced salt solution containing 10 mM HEPES at a pH of 7.4. The dosing solution concentration was 1 ?M for the test article in the assay buffer. Cell monolayers were dosed on the apical side (A-to-B) or basolateral side (B-to-A) and incubated at 37? C. under an atmosphere of 5% CO.sub.2 in a humidified incubator. Samples were taken from the donor and receiver chambers at 120 minutes. Each determination was performed in duplicate. After the 120 min transport period, the flux of lucifer yellow was also measured for each monolayer to ensure no damage was inflicted to the cell monolayers during the transport period. All samples were assayed by LC-MS/MS (Waters XSelect HSS T3 C18, 2.5 m, 2.1?50 mm) using electrospray ionization with 0.1% formic acid in water (mobile phase A) and 0.1% formic acid in acetonitrile (mobile phase B) as mobile phases. The apparent permeability coefficient (Papp), in units of cm per second, was calculated for MDCK-MDR1 Cells (NIH cell line) drug transport assays using the following equation:
Where V.sub.A is the volume (in mL) in the acceptor well, Area is the surface area of the membrane (0.143 cm.sup.2 for Transwell-96 Well Permeable Supports), and time is the total transport time in seconds.
The leakage of Lucifer Yellow (LY), in unit of percentage (%), can be calculated using the following equation:
LY leakage of <1% is acceptable to indicate the well-qualified MDCK-MDR1(NIH) monolayer.
[0792] The following comparator compounds were made using the procedures described above.

Brain Exposure Assay in Mice
[0794] This protocol was used to determine the brain-to-plasma ratio in vivo in mice post oral administration of test compounds. Mice (C57BL/6JNIFDC, male, non-fasted, 18-30 g body weight, 3 mice for each timepoint) were dosed orally at 100 mg/kg (10 mg test compound/mL formulation, 10 mL dosing volume/kg) with plasma and brain tissues obtained at 2- and 6-hours post-administration. The oral dosing formulation composition used was 10% N,N-dimethylacetamide:20% propylene glycol:70% of 40% aqueous 2-hydroxypropyl-?-cyclodextrin.
[0795] For the isolation of mouse plasma from dosed animals, approximately 0.3 mL blood was collected by orbital sinus bleed and centrifuged (4000 g, 5 minutes, 4? C.). The plasma samples were stored frozen at ?75?15? C. until further processing.
[0796] For the isolation of brain tissue from dosed animals, whole brain tissues were collected from euthanized and fully exsanguinated mice. The tissues were quickly rinsed with distilled water, dried with absorbent paper, followed by rapid freezing on dry ice and then storage at ?75?15? C. until further processing. Brain tissue samples obtained from frozen whole brain were weighed and the samples homogenized using three equivalents of distilled water (3 mL per gram of brain tissue).
[0797] Standard and quality control samples were prepared by adding 3 ?L of the test compound dimethyl sulfoxide (DMSO) stock solutions to blank plasma (30 ?L) and blank brain homogenate aliquots (30 ?L). Standard curves for brain and plasma were generated over a 1 to 1,000 ng/g test compound concentration range. For the extraction of test compound from plasma and brain tissue homogenate samples, a solution of acetonitrile containing internal standard (400 L) was added to 30 ?L of samples with added 3 ?L of DMSO. The samples then were vortex-mixed followed by centrifugation at 4000 rpm (4? C., 15 minutes). The resultant supernatants were diluted 5-fold with distilled water. Finally, 10 ?L of the diluted supernatant was injected onto an LC-MS/MS instrument for quantitative analysis of test compound.
[0798] The brain tissue concentration was calculated by multiplying the concentration of drug detected in the homogenized brain tissue sample by a dilution factor of 4.
[0799] The brain-to-plasma ratio was calculated by the relationship: Brain-to-plasma ratio=C.sub.brain/C.sub.plasma; where C.sub.b is the concentration in brain tissue and C.sub.p is the concentration in plasma at the corresponding timepoint.
[0800] Kp is the total brain-plasma concentration ratio; K.sub.p=C.sub.brain/C.sub.plasma.
[0801] Kp, uu is the unbound brain-to-plasma partition coefficient (K.sub.p,uu,brain). It is a measure of the extent of the distribution equilibrium of a compound between the unbound (free) fractions in brain and in blood plasma; K.sub.p, uu brain=C.sub.u, brain/C.sub.u, plasma.
[0802] A compound is estimated as brain penetrant if its brain-to-plasma concentration ratio is >0.04, as cerebral blood volume is estimated at 4% of total brain volume (Shaffer CL (2010), Defining Neuropharmacokinetic Parameters in CNS Drug Discovery to Determine Cross-Species Pharmacologic Exposure-Response Relationships, Annual Reports in Medicinal Chemistry, 45:55-70, https://doi.org/10.1016/S0065-7743(10)45004-6).
