The present invention relates generally to the field of medicinal chemistry. Specifically, the present invention provides compounds that inhibit Nicotinamide phosphoribosyltransferase (Nampt). The invention also provides methods for making these compounds, pharmaceutical compositions comprising these compounds, and methods for treating diseases with these compounds; particularly cancer, systemic or chronic inflammation, rheumatoid arthritis, diabetes, obesity, T-cell mediated autoimmune disease, ischemia, and other complications associated with these diseases and disorders, that respond favorably to the inhibition of Nampt.
Nicotinamide phosphoribosyltransferase (Nampt; also know as visfatin and pre-B-cell colony-enhancing factor 1 (PBEF)) catalyzes the condensation of nicotinamide (NaM) with 5-phosphoribosyl-1-pyrophosphate to yield nicotinamide mononucleotide. This is the first and rate-limiting step in one biosynthetic pathway that cells use to make nicotinamide adenine dinucleotide (NAD+).
NAD+ has many important cellular functions. Classically, it plays a role as a key coenzyme in metabolic pathways, where it continually cycles between its oxidized form (NAD+) and its reduced form (NADH). More recently, NAD+ has been shown to be involved in genome integrity maintainence, stress response, and Ca2+ signaling, where it is consumed by enzymes including poly(ADP-ribose) polymerases (PARPs), sirtuins, and cADP-ribose synthases, respectively. (Reviewed in Belenky, P. et al., NAD+ metabolism in health and disease. Trends Biochem. Sci. 32, 12-19 (2007).)
As a critical coenzyme in redox reactions, NAD+ is required in glycolysis and the citric acid cycle; where it accepts the high energy electrons produced and, as NADH, passes these electrons on to the electron transport chain. The NADH-mediated supply of high energy electrons is the driving force behind oxidative phosphorylation, the process by which the majority of ATP is generated in aerobic cells. Consequently, having sufficient levels of NAD+ available in the cell is critical for the maintenance of proper ATP levels in the cell. Understandably, reduction in cellular NAD+ levels by Nampt inhibition can be expected to eventually lead to depletion of ATP and, ultimately, cell death.
In view of the above, it is perhaps not surprising that inhibitors of Nampt are being developed as chemotherapeutic agents for the treatment of cancer. In fact, there are currently two Nampt inhibitors in clinical trials for the treatment of cancer (Holen, K. et al. The pharmacokinetics, toxicities, and biologic effects of FK866, a nicotinamide adenine dinucleotide biosynthesis inhibitor. Invest. New Drugs. 26, 45-51 (2008); Hovstadius, P. et al. A Phase I study of CHS 828 in patients with solid tumor malignancy. Clin. Cancer Res. 8, 2843-2850 (2002); Ravaud, A. et al., Phase I study and pharmacokinetic of CHS-828, a guanidino-containing compound, administered orally as a single dose every 3 weeks in solid tumours: an ECSG/EORTC study. Eur. J. Cancer. 41, 702-707 (2005); and von Heideman, A. et al. Safety and efficacy of NAD depleting cancer drugs: results of a phase I clinical trial of CHS 828 and overview of published data. Cancer Chemother. Pharmacol. (2009) Sep. 30 [Epub ahead of print]).
Consequently, there is a clear need for compounds that inhibit Nampt, which can not only be used in the treatment of cancer, but can also be used in the treatment of systemic or chronic inflammation, rheumatoid arthritis, diabetes, obesity, T-cell mediated autoimmune disease, ischemia, and other complications associated with these diseases and disorders.
The present invention provides chemical compounds that inhibit the activity of Nampt. These compounds can be used in the treatment of cancer, systemic or chronic inflammation, rheumatoid arthritis, diabetes, obesity, T-cell mediated autoimmune disease, ischemia, and other complications associated with these diseases and disorders.

The term “cycloalkyl” as used herein by itself or as part of another group refers to a fully saturated 3- to 8-membered cyclic hydrocarbon ring (i.e., a cyclic form of an alkyl) alone (“monocyclic cycloalkyl”) or fused to another cycloalkyl, cycloalkynyl, cycloalkenyl, heterocycle, aryl or heteroaryl ring (i.e., sharing an adjacent pair of carbon atoms with other such rings) (“polycyclic cycloalkyl”). Thus, a cycloalkyl can exist as a monocyclic ring, bicyclic ring, or a spiral ring. When a cycloalkyl is referred to as a Cx cycloalkyl, this means a cycloalkyl in which the fully saturated cyclic hydrocarbon ring (which may or may not be fused to another ring) has x number of carbon atoms. When a cycloalkyl is recited as a substituent on a chemical entity, it is intended that the cycloalkyl moiety is attached to the entity through a single carbon atom within the fully saturated cyclic hydrocarbon ring of the cycloalkyl. In contrast, a substituent on a cycloalkyl can be attached to any carbon atom of the cycloalkyl. A cycloalkyl group can be unsubstituted or substituted with one or more substitutents so long as the resulting compound is sufficiently stable and suitable for use in the embodiments of the present invention. Examples of cycloalkyl groups include, for example, cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl and cycloheptyl.
The term “cycloalkenyl” as used herein by itself or as part of another group refers to a non-aromatic partially saturated 3- to 8-membered cyclic hydrocarbon ring having a double bond therein (i.e., a cyclic form of an alkenyl) alone (“monocyclic cycloalkenyl”) or fused to another cycloalkyl, cycloalkynyl, cycloalkenyl, heterocycle, aryl or heteroaryl ring (i.e., sharing an adjacent pair of carbon atoms with such other rings) (“polycyclic cycloalkenyl”). Thus, a cycloalkenyl can exist as a monocyclic ring, bicyclic ring, polycyclic or a spiral ring. When a cycloalkenyl is referred to as a Cx cycloalkenyl, this means a cycloalkenyl in which the non-aromatic partially saturated cyclic hydrocarbon ring (which may or may not be fused to another ring) has x number of carbon atoms. When a cycloalkenyl is recited as a substituent on a chemical entity, it is intended that the cycloalkenyl moiety is attached to the entity through a carbon atom within the non-aromatic partially saturated ring (having a double bond therein) of the cycloalkenyl. In contrast, a substituent on a cycloalkenyl can be attached to any carbon atom of the cycloalkenyl. A cycloalkenyl group can be in an unsubstituted form or substituted form with one or more substitutents. Examples of cycloalkenyl groups include cyclopentenyl, cycloheptenyl and cyclooctenyl.
The term “heterocycle” (or “heterocyclyl” or “heterocyclic” or “heterocyclo”) as used herein by itself or as part of another group means a saturated or partially saturated 3-7 membered non-aromatic cyclic ring formed with carbon atoms and from one to four heteroatoms independently selected from the group consisting of O, N, and S, wherein the nitrogen and sulfur heteroatoms can be optionally oxidized, and the nitrogen can be optionally quaternized (“monocyclic heterocycle”). The term “heterocycle” also encompasses a group having the non-aromatic heteroatom-containing cyclic ring above fused to another monocyclic cycloalkyl, cycloalkynyl, cycloalkenyl, heterocycle, aryl or heteroaryl ring (i.e., sharing an adjacent pair of atoms with such other rings) (“polycyclic heterocycle”). Thus, a heterocycle can exist as a monocyclic ring, bicyclic ring, polycyclic or a spiral ring.

In contrast, a substituent on a heterocycle can be attached to any suitable atom of the heterocycle. In a “saturated heterocycle” the non-aromatic heteroatom-containing cyclic ring described above is fully saturated, whereas a “partially saturated heterocyle” contains one or more double or triple bonds within the non-aromatic heteroatom-containing cyclic ring regardless of the other ring it is fused to. A heterocycle can be in an unsubstituted form or substituted form with one or more substituents so long as the resulting compound is sufficiently stable and suitable for use in the embodiments of the present invention.
Some examples of saturated or partially saturated heterocyclic groups include tetrahydrofuranyl, pyranyl, piperidinyl, piperazinyl, pyrrolidinyl, imidazolidinyl, imidazolinyl, indolinyl, isoindolinyl, quinuclidinyl, morpholinyl, isochromanyl, chromanyl, pyrazolidinyl, pyrazolinyl, tetronoyl and tetramoyl groups.
As used herein, “aryl” by itself or as part of another group means an all-carbon aromatic ring with up to 7 carbon atoms in the ring (“monocylic aryl”).

When an aryl is referred to as a Cx aryl, this means an aryl in which the all-carbon aromatic ring (which may or may not be fused to another ring) has x number of carbon atoms. When an aryl is recited as a substituent on a chemical entity, it is intended that the aryl moiety is attached to the entity through an atom within the all-carbon aromatic ring of the aryl. In contrast, a substituent on an aryl can be attached to any suitable atom of the aryl. Examples, without limitation, of aryl groups are phenyl, naphthalenyl and anthracenyl. An aryl can be in an unsubstituted form or substituted form with one or more substituents so long as the resulting compound is sufficiently stable and suitable for use in the embodiments of the present invention.
The term “heteroaryl” as employed herein refers to a stable aromatic ring having up to 7 ring atoms with 1, 2, 3 or 4 hetero ring actoms in the ring which are oxygen, nitrogen or sulfur or a combination thereof (“monocylic heteroaryl”). In addition to monocyclic hetero-aromatic rings, the term “heteroaryl” also encompasses a group having the monocyclic hetero-aromatic ring above fused to another cycloalkyl, cycloalkynyl, cycloalkenyl, heterocycle, aryl or heteroaryl ring (i.e., sharing an adjacent pair of atoms with such other rings) (“polycyclic heteroaryl”). When a heteroaryl is recited as a substituent on a chemical entity, it is intended that the heteroaryl moiety is attached to the entity through an atom within the heteroaromatic ring of the heteroaryl. In contrast, a substituent on a heteroaryl can be attached to any suitable atom of the heteroaryl.

In preferred embodiments, compounds of the present invention are provided having an IC50 of less than about 100 nM, such as, for example, the compounds listed in Tables 1A and 1B and 3A and 3B, as determined in the cytotoxicity assays as described in the Examples below (i.e., Cytotoxicity Assays).
In all compounds of the present invention, such as, for example, the compounds of Formulae I, Ia, Ia1, Ia2, Ib, Ib1, Ib2, Ib3, Ic, Id, II, IIa, IIa1, IIa2, IIa3, IIa4, IIb, IIb1, IIb2, IIb3, IIb4, IIb5, IIb6, IIb7, IIc, IIc1, IId, IId1, III, IIIa, IIIa1, IIIa2, IIIa3, IIIa4, IIIa5, IIIa6, IIIb, IIIb1, IIIb2, IIIb3, IIIb4, IIIb5, IIIb6, IIIb7, IIIb8, IIIb9, IIIb100, IIIb11, IIIc, IV, IVa, IVa1, IVa2, Iva3, IVa4, IVa5, IVa6, IVb, IVb1, IVb2, IVb3, IVb4, IVb5, IVb6, IVb7, IVb8, and IVc, as illustrated herein, and the compounds of Tables 1A and 1B, 2, 3A and 3B, 4, 5, and 6, reference to any bound hydrogen atom can also encompass a deuterium atom bound at the same position. Substitution of hydrogen atoms with deuterium atoms is conventional in the art. See, e.g., U.S. Pat. Nos. 5,149,820 & 7,317,039, which are incorporated by reference herein their entirety. Such deuteration sometimes results in a compound that is functionally indistinct from its hydrogenated counterpart, but occasionally results in a compound having beneficial changes in the properties relative to the non-deuterated form. For example, in certain instances, replacement of specific bound hydrogen atoms with deuterium atoms slows the catabolism of the deuterated compound, relative to the non-deuterated compound, such that the deuterated compound exhibits a longer half-life in the bodies of individuals administered such compounds. This particularly so when the catabolism of the hydrogenated compound is mediated by cytochrome P450 systems. See Kushner et al., Can. J. Physiol. Pharmacol. (1999) 77:79-88, which is incorporated by reference herein its entirety.

In some embodiments, the patient is a human patient.
In some embodiments, the method comprises identifying a patient in need of such treatment. A patient having cancer can be identified by conventional diagnostic techniques known in the art, as well as by those methods discussed herein below.
As noted previously, Nampt catalyzes the first and rate-limiting step in the generation of NAD+ from NaM, and NAD+ is critical for the generation of cellular ATP by glycolysis, the citric acid cycle, and oxidative phosphorylation. By these mechanisms and others, reduction in cellular NAD+ levels by Nampt inhibition causes depletion of cellular ATP and, ultimately, cell death. Tumor cells are thought to be more sensitive to NAD+ and ATP loss than normal cells due to their higher energy needs and an increased reliance on glycolysis. Known as the “Warburg effect” (Warburg, O. On respiratory impairment in cancer cells. Science 124, 269-270 (1956)), a wide spectrum of cancer cells exhibit increased glycolysis relative to oxidative phosphorylation, despite the availability of oxygen. The shift from oxidative phosphorylation to a reliance on glycolysis is thought to result from mitochondrial damage and/or a hypoxic tumor microenvironment (reviewed in Hsu, P. P and Sabatini, D. M. Cancer cell metabolism: Warburg and beyond. Cell 134, 703-707 (2008)) and/or cellular reprogramming by oncogenes and/or tumor suppressors (reviewed in Levine, A. J. and Puzio-Kuter A. M. Science. 330, 1340-1344 (2010)). With regards to depleting energy levels in tumor cells, Nampt inhibitors would be analogous to inhibitors of other glycolytic enzymes, several of which are in cancer preclinical or clinical trials (reviewed in Pelicano H. et al. Glycolysis inhibition for anticancer treatment. Oncogene 25, 4633-4646 (2006)).
In addition to increased energy needs, tumor cells are more susceptible to NAD+ loss due to a higher turnover of NAD+ in response to DNA damage and genomic instability. According to this model, poly(ADP-ribose) polymerases (PARPs) consume NAD+ as they generate poly(ADP-ribose) to repair DNA in response to alkylating agents, ionizing radiation, and oxidative stress (reviewed in Galli M. et al. The nicotinamide phosphoribosyltransferase: a molecular link between metabolism, inflammation, and cancer. Cancer Res. 70, 8-11 (2010)). Indeed, an inability to replenish this NAD+ loss, either by reducing Nampt expression or inhibiting Nampt activity, sensitizes cells to PARP activation (Rongvaux, et al. Nicotinamide phosphoribosyl transferase/pre-B cell colony-enhancing factor/visfatin is required for lymphocyte development and cellular resistance to genotoxic stress. J. Immunol. 181, 4685-4695 (2008)).
The increased metabolic demands of cancer cells (Luo et al., Cell. 136(5):823-37 (2009). Erratum in: Cell., 2009 Aug. 21; 138(4):807.)) suggests that they should require NAD+ in sufficient levels to maintain cellular pools of ATP. This requirement, and the critical role played by Nampt in NAD+ synthesis further suggests that cancer cells have a critical need for adequate Nampt activity. Consistent with this hypothesis are reports of Nampt over-expression in colon cancers (Hufton et al., FEBS Lett. 463(1-2):77-82 (1999), Van Beijnum et al., Int. J. Cancer. 101(2):118-27 (2002)), ovarian cancers (Shackelford et al., Int J. Clin. Exp. Pathol. 3(5): 522-527 (2010)), prostate cancers (Wang et al., Oncogene 30: 907-921 (2011)) and GBM cancers (Reddy et al., Cancer Biol. Ther. 7(5):663-8 (2008)), and suggestions of the amplification of the gene encoding Nampt in multiple other cancers. Immunohistochemistry analyses suggest strong expression of Nampt occurs in greater than 20% of biopsies of: breast, lung, malignant lymphoma, ovarian, pancreatic, prostate and testicular cancers (www.proteinatlas.org). In addition to the role played by NAD+ as a cofactor in redox reactions, NAD+ also serves as a substrate for mono and poly-ADP ribosyltransferases (PARPs), class III histone deacetylases (sirtuins) and ADP-ribose cyclases. PARPs appear to be major consumers of cellular NAD+ (Paine et al., Biochem. J. 202(2):551-3 (1982)), and evidence exists for increased polyADP-ribosylation activity in oral cancer (Das, B. R., Cancer Lett. 73(1):29-34 (1993)), hepatocellular carcinoma (Shiobara et al., J. Gastroenterol. Hepatol. 16(3):338-44 (2001), Nomura et al., J Gastroenterol. Hepatol. 15(5):529-35 (2000)), rectal cancer (Yalcintepe et al., Braz. J. Med. Biol. Res. 38(3):361-5 (2005); Epub 2005, Mar. 8.), and leukemia and ovarian cancers (Singh N, Cancer Lett. 58(1-2):131-5 (1991)). Increased ADP-ribosylation in cancer can reflect PARPs' role in DNA repair (Durkacz et al., Nature. 283(5747):593-6 (1980); deMurcia et al., Proc. Natl. Acad. Sci. U.S.A. 94(14):7303-7 (1997), Simbulan-Rosenthal et al., Proc. Natl. Acad. Sci. U.S.A. 96(23):13191-6 (1999)) and the need to maintain genome integrity in the face of genomic instability and the resulting accumulation of point mutations, deletions, chromosomal rearrangement and aneuploidy (Hartwell and Kastan, Science. 266(5192):1821-8 (1994)). PARP-1 itself is reported to be over-expressed in breast cancer, where its expression inversely correlates with genomic instability (Biechi et al., Clin. Cancer Res. 2(7):1163-7 (1996)).
Furthermore, the Nampt transcript is known to be upregulated in colon cancers (van Beijnum J R, et al. Target validation for genomics using peptide-specific phage antibodies: a study of five gene products overexpressed in colorectal cancer. Int. J. Cancer. 101, 118-127 (2002); and Hufton S E, et al. A profile of differentially expressed genes in primary colorectal cancer using suppression subtractive hybridization. FEBS Lett. 463, 77-82 (1999)) and glioblastoma cancers (Reddy P S, et al. PBEF1/NAmPRTase/Visfatin: a potential malignant astrocytoma/glioblastoma serum marker with prognostic value. Cancer Biol. Ther. 7, 663-668 (2008)), and it remains possible that the Nampt gene is amplified in other cancers.
Thus, in one embodiment, the present invention provides a method of treating a cancer that overexpresses Nampt, comprising administering a therapeutically effective amount of one or more compounds of the present invention, such as, for example, the compounds of Formulae I, Ia, Ia1, Ia2, Ib, Ib1, Ib2, Ib3, Ic, Id, II, IIa, IIa1, IIa2, IIa3, IIa4, IIb, IIb1, IIb2, IIb3, IIb4, IIb5, IIb6, IIb7, IIc, IIc1, IId, IId1, III, IIIa, IIIa1, IIIa2, IIIa3, IIIa4, IIIa5, IIIa6, IIIb, IIIb1, IIIb2, IIIb3, IIIb4, IIIb5, IIIb6, IIIb7, IIIb8, IIIb9, IIIb10, IIIb11, IIIc, IV, IVa, IVa1, IVa2, Iva3, IVa4, IVa5, IVa6, IVb, IVb1, IVb2, IVb3, IVb4, IVb5, IVb6, IVb7, IVb8, and IVc, as illustrated herein, and the compounds of Tables 1A and 1B, 2, 3A and 3B, 4, 5, and 6, or a pharmaceutical composition comprising one or more compounds of the present invention, such as, for example, the compounds of Formulae I, Ia, Ia1, Ia2, Ib, Ib1, Ib2, Ib3, Ic, Id, II, IIa, IIa1, IIa2, IIa3, IIa4, IIb, IIb1, IIb2, IIb3, IIb4, IIb5, IIb6, IIb7, IIc, IIc1, IId, IId1, III, IIIa, IIIa1, IIIa2, IIIa3, IIIa4, IIIa5, IIIa6, IIIb, IIIb1, IIIb2, IIIb3, IIIb4, IIIb5, IIIb6, IIIb7, IIIb8, IIIb9, IIIb10, IIIb11, IIIc, IV, IVa, IVa1, IVa2, Iva3, IVa4, IVa5, IVa6, IVb, IVb1, IVb2, IVb3, IVb4, IVb5, IVb6, IVb7, IVb8, and IVc, as illustrated herein, and the compounds of Tables 1A and 1B, 2, 3A and 3B, 4, 5, and 6, to a patient.

As used herein, the term “cancer” has its conventional meaning in the art. Cancer includes any condition of the animal or human body characterized by abnormal cellular proliferation. The cancers to be treated comprise a group of diseases characterized by the uncontrolled growth and spread of abnormal cells. Compounds of the present invention have been shown to be effective in a variety of standard cancer models, and are thus thought to have utility in treating a broad range of cancers. However, preferred methods of the invention involve treating cancers that have been found to respond favorably to treatment with Nampt inhibitors. Further, “treating cancer” should be understood as encompassing treating a patient who is at any one of the several stages of cancer, including diagnosed but as yet asymptomatic cancer.
Specific cancers that can be treated by the methods of the invention are those cancers that respond favorably to treatment with a Nampt inhibitor. Such cancers include, but are not limited to, Hodgkin's disease, non-Hodgkin's lymphoma, acute lymphocytic leukemia, chronic lymphocytic leukemia, acute myeloid leukemia, mantle-cell lymphoma, multiple myeloma, neuroblastoma, breast carcinoma, ovarian carcinoma, lung carcinoma, Wilms' tumor, cervical carcinoma, testicular carcinoma, soft-tissue sarcoma, primary macroglobulinemia, bladder carcinoma, chronic granulocytic leukemia, primary brain carcinoma, malignant melanoma, small-cell lung carcinoma, stomach carcinoma, colon carcinoma, malignant pancreatic insulinoma, malignant carcinoid carcinoma, choriocarcinoma, mycosis fungoides, head or neck carcinoma, osteogenic sarcoma, pancreatic carcinoma, acute granulocytic leukemia, hairy cell leukemia, neuroblastoma, rhabdomyosarcoma, Kaposi's sarcoma, genitourinary carcinoma, thyroid carcinoma, esophageal carcinoma, malignant hypercalcemia, cervical hyperplasia, renal cell carcinoma, endometrial carcinoma, polycythemia vera, essential thrombocytosis, adrenal cortex carcinoma, skin cancer, and prostatic carcinoma.
a. 1 Methods of Identifying Cancers Most Likely to be Susceptible to Treatment with Nampt Inhibitors
Importantly, NAD+ can be generated by several Nampt-independent pathways as well, including: (1) de novo synthesis from L-tryptophan via the kynurenine pathway; (2) from nicotinic acid (NA) via the Preiss-Handler pathway; and (3) from nicotinamide riboside or nicotinic acid riboside via nicotinamide/nicotinic acid riboside kinases (reviewed in Khan, J. A. et al., Nicotinamide adenine dinucleotide metabolism as an attractive target for drug discovery. Expert Opin. Ther. Targets. 11(5):695-705 (2007)). However, these different routes of NAD+ synthesis are generally tissue specific: The de novo pathway is present in liver, brain, and immune cells, the Priess-Handler pathway is primarily active in the liver, kidney, and heart, and Nrk2, of the nicotinamide riboside kinase pathway, is expressed in brain, heart, and skeletal muscle (Bogan, K. L. and Brenner, C. Nicotinic acid, nicotinamide, and nicotinamide riboside: a molecular evaluation of NAD+ precursor vitamins in human nutrition. Annu. Rev. Nutr. 28:115-30 (2008) and Tempel, W. et al., Nicotinamide riboside kinase structures reveal new pathways to NAD+. PLoS Biol. 5(10):e263 (2007)).
Of these alternative pathways of NAD+ synthesis, the Preiss-Handler pathway is perhaps the most important for cancer cells. The first and rate-limiting step of this pathway, the conversion of nicotinic acid (NA) to nicotinic acid mononucleotide (NAMN), is catalyzed by the enzyme Naprt 1.
While not wishing to be bound by theory it follows, therefore, that one way to stratify patients and to potentially expand the therapeutic window of the compounds of the present invention would be to identify those cancers with reduced or absent levels of Naprt1 expression. Such cancers would theoretically be less able to replace cellular NAD+ through this alternative pathway, while being treated with Nampt inhibitors. Hence, they should be more sensitive to treatment by the compounds of the present invention.
Accordingly, embodiments of the present invention include a method of identifying a cancer that is likely susceptible to treatement with a compound of the present invention, such as, for example, a compound of Formulae I, Ia, Ia1, Ia2, Ib, Ib1, Ib2, Ib3, Ic, Id, II, IIa, IIa1, IIa2, IIa3, IIa4, IIb, IIb1, IIb2, IIb3, IIb4, IIb5, IIb6, IIb7, IIc, IIc1, IId, IId1, III, IIIa, IIIa1, IIIa2, IIIa3, IIIa4, IIIa5, IIIa6, IIIb, IIIb1, IIIb2, IIIb3, IIIb4, IIIb5, IIIb6, IIIb7, IIIb8, IIIb9, IIIb10, IIIb11, IIIc, IV, IVa, IVa1, IVa2, Iva3, IVa4, IVa5, IVa6, IVb, IVb1, IVb2, IVb3, IVb4, IVb5, IVb6, IVb7, IVb8, and IVc, as illustrated herein, and a compound of Tables 1A and 1B, 2, 3A and 3B, 4, 5, and 6. The method comprises obtaining a biopsy sample of said cancer, determining the expression level of enzymes in pathways for NAD biosynthesis (e.g. tryptophan, kynurenine pathway, nicotinic acid salvage pathway, nicotinamide riboside pathway), relative to a non-cancerous control tissue, wherein, if the expression level of enzymes in such pathways (e.g. Naprt1, Qprt, NRK-1) is reduced, relative to a non-cancerous control tissue, the cancer is identified as likely susceptible to treatement with a compound of the present invention.
In some of such embodiments, the methods of determining the expression level of the Naprt1 gene involve either determining levels of expression of the Naprt1-encoding transcript (i.e., Naprt1-encoding mRNA), or determining levels of expression of the Naprt1 protein itself. For these embodiments, any acceptable means of determining expression levels of either the Naprt1-encoding transcript, or the Naprt1 protein itself, can be utilized, and such acceptable means are well within the skill level of the artisan versed in determining expression levels of eukaryotic genes. Such acceptable means can include, for example, quantitative PCR (qPCR) to measure levels of Naprt1-encoding transcript, or ELISAs to measure levels of expressed Naprt1 protein. The specific methods involved in determining the expression of particular eukaryotic genes are well known in the art.
Additionally, embodiments of the present invention include a method of treating cancer, wherein cells of the cancer exhibit low levels of Naprt1 expression. Thus, in one embodiment, the present invention provides a method of treating a cancer that exhibit low levels of Naprt1 expression, comprising administering a therapeutically effective amount of one or more compounds of the present invention, such as, for example, the compounds of Formulae I, Ia, Ia1, Ia2, Ib, Ib1, Ib2, Ib3, Ic, Id, II, IIa, IIa1, IIa2, IIa3, IIa4, IIb, IIb1, IIb2, IIb3, IIb4, IIb5, IIb6, IIb7, IIc, IIc1, IId, IId1, III, IIIa, IIIa1, IIIa2, IIIa3, IIIa4, IIIa5, IIIa6, IIIb, IIIb1, IIIb2, IIIb3, IIIb4, IIIb5, IIIb6, IIIb7, IIIb8, IIIb9, IIIb10, IIIb11, IIIc, IV, IVa, IVa1, IVa2, Iva3, IVa4, IVa5, IVa6, IVb, IVb1, IVb2, IVb3, IVb4, IVb5, IVb6, IVb7, IVb8, and IVc, as illustrated herein, and the compounds of Tables 1A and 1B, 2, 3A and 3B, 4, 5, and 6, or a pharmaceutical composition comprising one or more compounds of the present invention, such as, for example, the compounds of Formulae I, Ia, Ia1, Ia2, Ib, Ib1, Ib2, Ib3, Ic, Id, II, IIa, IIa1, IIa2, IIa3, IIa4, IIb, IIb1, IIb2, IIb3, IIb4, IIb5, IIb6, IIb7, IIc, IIc1, IId, IId1, III, IIIa, IIIa1, IIIa2, IIIa3, IIIa4, IIIa5, IIIa6, IIIb, IIIb1, IIIb2, IIIb3, IIIb4, IIIb5, IIIb6, IIIb7, IIIb8, IIIb9, IIIb10, IIIb11, IIIc, IV, IVa, IVa1, IVa2, Iva3, IVa4, IVa5, IVa6, IVb, IVb1, IVb2, IVb3, IVb4, IVb5, IVb6, IVb7, IVb8, and IVc, as illustrated herein, and the compounds of Tables 1A and 1B, 2, 3A and 3B, 4, 5, and 6, to a patient.
Cell lines were treated with exemplary compounds of the present invention and screened for NA rescue and Naprt1 expression by immunoblotting and quantitative RT-PCR (See NA Rescue and Naprt1 Expression Assays section below). Naprt1 expression was least in brain cancers, lung cancers, lymphoma, myeloma and osteosarcoma. Further, glioblastoma and sarcoma cell lines that are reported to be resistant to NA rescue have been found to have reduced Naprt1 expression (Watson, et al. Mol. Cell. Biol. 29(21):5872-88 (2009)).
Thus, in one embodiment, the present invention provides a method of treating brain cancer, such as glioblastoma, comprising administering a therapeutically effective amount of one or more compounds of the present invention, such as, for example, the compounds of Formulae I, Ia, Ia1, Ia2, Ib, Ib1, Ib2, Ib3, Ic, Id, II, IIa, IIa1, IIa2, IIa3, IIa4, IIb, IIb1, IIb2, IIb3, IIb4, IIb5, IIb6, IIb7, IIc, IIc1, IId, IId1, III, IIIa, IIIa1, IIIa2, IIIa3, IIIa4, IIIa5, IIIa6, IIIb, IIIb1, IIIb2, IIIb3, IIIb4, IIIb5, IIIb6, IIIb7, IIIb8, IIIb9, IIIb10, IIIb11, IIIc, IV, IVa, IVa1, IVa2, Iva3, IVa4, IVa5, IVa6, IVb, IVb1, IVb2, IVb3, IVb4, IVb5, IVb6, IVb7, IVb8, and IVc, as illustrated herein, and the compounds of Tables 1A and 1B, 2, 3A and 3B, 4, 5, and 6, or a pharmaceutical composition comprising one or more compounds of the present invention, such as, for example, the compounds of Formulae I, Ia, Ia1, Ia2, Ib, Ib1, Ib2, Ib3, Ic, Id, II, IIa, IIa1, IIa2, IIa3, IIa4, IIb, IIb1, IIb2, IIb3, IIb4, IIb5, IIb6, IIb7, IIc, IIc1, IId, IId1, III, IIIa, IIIa1, IIIa2, IIIa3, IIIa4, IIIa5, IIIa6, IIIb, IIIb1, IIIb2, IIIb3, IIIb4, IIIb5, IIIb6, IIIb7, IIIb8, IIIb9, IIIb10, IIIb11, IIIc, IV, IVa, IVa1, IVa2, Iva3, IVa4, IVa5, IVa6, IVb, IVb1, IVb2, IVb3, IVb4, IVb5, IVb6, IVb7, IVb8, and IVc, as illustrated herein, and the compounds of Tables 1A and 1B, 2, 3A and 3B, 4, 5, and 6, to a patient.
Thus, in one embodiment, the present invention provides a method of treating lung cancer, comprising administering a therapeutically effective amount of one or more compounds of the present invention, such as, for example, the compounds of Formulae I, Ia, Ia1, Ia2, Ib, Ib1, Ib2, Ib3, Ic, Id, II, IIa, IIa1, IIa2, IIa3, IIa4, IIb, IIb1, IIb2, IIb3, IIb4, IIb5, IIb6, IIb7, IIc, IIc1, IId, IId1, III, IIIa, IIIa1, IIIa2, IIIa3, IIIa4, IIIa5, IIIa6, IIIb, IIIb1, IIIb2, IIIb3, IIIb4, IIIb5, IIIb6, IIIb7, IIIb8, IIIb9, IIIb10, IIIb11, IIIc, IV, IVa, IVa1, IVa2, Iva3, IVa4, IVa5, IVa6, IVb, IVb1, IVb2, IVb3, IVb4, IVb5, IVb6, IVb7, IVb8, and IVc, as illustrated herein, and the compounds of Tables 1A and 1B, 2, 3A and 3B, 4, 5, and 6, or a pharmaceutical composition comprising one or more compounds of the present invention, such as, for example, the compounds of Formulae I, Ia, Ia1, Ia2, Ib, Ib1, Ib2, Ib3, Ic, Id, II, IIa, IIa1, IIa2, IIa3, IIa4, IIb, IIb1, IIb2, IIb3, IIb4, IIb5, IIb6, IIb7, IIc, IIc1, IId, IId1, III, IIIa, IIIa1, IIIa2, IIIa3, IIIa4, IIIa5, IIIa6, IIIb, IIIb1, IIIb2, IIIb3, IIIb4, IIIb5, IIIb6, IIIb7, IIIb8, IIIb9, IIIb10, IIIb11, IIIc, IV, IVa, IVa1, IVa2, Iva3, IVa4, IVa5, IVa6, IVb, IVb1, IVb2, IVb3, IVb4, IVb5, IVb6, IVb7, IVb8, and IVc, as illustrated herein, and the compounds of Tables 1A and 1B, 2, 3A and 3B, 4, 5, and 6, to a patient.
Thus, in one embodiment, the present invention provides a method of treating osteosarcoma cancer, comprising administering a therapeutically effective amount of one or more compounds of the present invention, such as, for example, the compounds of Formulae I, Ia, Ia1, Ia2, Ib, Ib1, Ib2, Ib3, Ic, Id, II, IIa, IIa1, IIa2, IIa3, IIa4, IIb, IIb1, IIb2, IIb3, IIb4, IIb5, IIb6, IIb7, IIc, IIc1, IId, IId1, III, IIIa, IIIa1, IIIa2, IIIa3, IIIa4, IIIa5, IIIa6, IIIb, IIIb1, IIIb2, IIIb3, IIIb4, IIIb5, IIIb6, IIIb7, IIIb8, IIIb9, IIIb10, IIIb11, IIIc, IV, IVa, IVa1, IVa2, Iva3, IVa4, IVa5, IVa6, IVb, IVb1, IVb2, IVb3, IVb4, IVb5, IVb6, IVb7, IVb8, and IVc, as illustrated herein, and the compounds of Tables 1A and 1B, 2, 3A and 3B, 4, 5, and 6, or a pharmaceutical composition comprising one or more compounds of the present invention, such as, for example, the compounds of Formulae I, Ia, Ia1, Ia2, Ib, Ib1, Ib2, Ib3, Ic, Id, II, IIa, IIa1, IIa2, IIa3, IIa4, IIb, IIb1, IIb2, IIb3, IIb4, IIb5, IIb6, IIb7, IIc, IIc1, IId, IId1, III, IIIa, IIIa1, IIIa2, IIIa3, IIIa4, IIIa5, IIIa6, IIIb, IIIb1, IIIb2, IIIb3, IIIb4, IIIb5, IIIb6, IIIb7, IIIb8, IIIb9, IIIb10, IIIb11, IIIc, IV, IVa, IVa1, IVa2, Iva3, IVa4, IVa5, IVa6, IVb, IVb1, IVb2, IVb3, IVb4, IVb5, IVb6, IVb7, IVb8, and IVc, as illustrated herein, and the compounds of Tables 1A and 1B, 2, 3A and 3B, 4, 5, and 6, to a patient.
In view of the NA rescue phenomenon described above, while those cancers with reduced or absent levels of Naprt1 expression should be more susceptible to treatment with the Nampt inhibitors of the present invention, administration of NA to patients having such cancers could prevent toxicity in other tissues associated with Nampt inhibition.
To support this concept, experiments were conducted to show that mice given NA survive doses of a Nampt inhibitor above the maximum tolerated dose (see also Beauparlant P., et al. Preclinical development of the nicotinamide phosphoribosyl transferase inhibitor prodrug GMX1777. Anticancer Drugs. 20(5):346-54 (2009) and Watson, et al. The small molecule GMX1778 is a potent inhibitor of NAD+ biosynthesis: strategy for enhanced therapy in nicotinic acid phosphoribosyltransferase 1-deficient tumors. Mol. Cell. Biol. 29(21):5872-88 (2009)). This phenomenon is referred to in the art as “NA rescue.”
Cell lines were treated with exemplary compounds of the present invention and screened for NA rescue and Naprt1 expression by immunoblotting and quantitative RT-PCR. Lack of NA rescue was greatest in brain cancers, lung cancers, lymphoma, myeloma, and osteosarcoma. Further, glioblastoma and sarcoma cell lines that are reported to be resistant to NA rescue have been found to have reduced Naprt1 expression (Watson, et al. Mol. Cell. Biol. 29(21):5872-88 (2009)).
Accordingly, in some embodiments, the methods of treating cancer disclosed herein further comprise administering nicotinic acid, or a compound capable of forming nicotinic acid in vivo, to the patient in addition to administering a compound of the present invention, such as, for example, a compound of Formulae I, Ia, Ia1, Ia2, Ib, Ib1, Ib2, Ib3, Ic, Id, II, IIa, IIa1, IIa2, IIa3, IIa4, IIb, IIb1, IIb2, IIb3, IIb4, IIb5, IIb6, IIb7, IIc, IIc1, IId, IId1, III, IIIa, IIIa1, IIIa2, IIIa3, IIIa4, IIIa5, IIIa6, IIIb, IIIb1, IIIb2, IIIb3, IIIb4, IIIb5, IIIb6, IIIb7, IIIb8, IIIb9, IIIb10, IIIb11, IIIc, IV, IVa, IVa1, IVa2, Iva3, IVa4, IVa5, IVa6, IVb, IVb1, IVb2, IVb3, IVb4, IVb5, IVb6, IVb7, IVb8, and IVc, as illustrated herein, and a compound of Tables 1A and 1B, 2, 3A and 3B, 4, 5, and 6. In some of such embodiments, the compound of the present invention is able to be administered at dose that exceeds the maximum tolerated dose for that particular compound of the present invention as determined for mono-therapy.
In some of such embodiments, administering NA may include administering NA prior to administering one or more of the compounds of the present invention, co-administering NA with one or more of the compounds of the present invention, or first treating the patient with one or more of the compounds of the present invention, followed by thereafter administering NA.
b. Treating Systemic or Chronic Inflammation
Nampt expression in visceral adipose tissue has been found to correlate with the expression of proinflammatory genes, CD68 and TNFα (Chang et al.; Metabolism. 59(1):93-9 (2010)). Several studies have noted an increase in reactive oxygen species and activation of NF-kappaB in response to Nampt expression (Oita et al.; Pflugers Arch. (2009); Romacho et al.; Diabetologia. 52(11):2455-63 (2009)). Nampt serum levels were found to have been increased in patients with inflammatory bowel diseases and correlated with disease activity (Moschen et al.; Mutat. Res. (2009)). One study has even suggested a specific mechanism for Nampt in inflammation: High levels of Nampt increase cellular NAD+ levels leading to a post-transcriptional upregulation of TNF via the NAD-dependent deacetylase, SirT6 (Van Gool et al. Nat. Med. 15(2):206-10 (2009)). Further, inhibition of Nampt reduced levels of inflammatory cytokines IL-6 and TNF-α (Busso et al. PLoS One. 21; 3(5):e2267 (2008)). In another study, Nampt inhibition was found to prevent TNF-α and IFN-γ production in T-lymphocytes (Bruzzone et al.; PLoS One.; 4(11):e7897 (2009)).
In view of the above, it is believed that inhibition of Nampt activity would be effective in treating systemic or chronic inflammation resulting from a wide range of causes. Consequently, the present invention provides methods of treating systemic or chronic inflammation by administering therapeutically effective amounts of one or more of the compounds of the present invention.
c. Treating Rheumatoid Arthritis
Nampt levels increased in a mouse model of arthritis and treatment of these mice with a Nampt inhibitor reduced the arthritis symptoms (Busso et al. PLoS One. 21; 3(5):e2267 (2008)). Also, because Nampt inhibition can decrease the activity of poly(ADP ribose) polymerases (PARPs) through the dependence of PARPs on NAD as a substrate, Nampt inhibitors, either alone or in combination with PARP inhibitors can be efficacious in any ailment treatable by PARP inhibitors. In this regard, PARP inhibitors have shown efficacy in models of arthritis (Kroger et al. Inflammation. 20(2):203-215 (1996)).
In view of the above, it is believed that inhibition of Nampt activity would be effective in treating RA. Consequently, the present invention provides methods of treating RA by administering therapeutically effective amounts of one or more of the compounds of the present invention, either alone, or in combination with a PARP inhibitor.
d. Treating Obesity and Diabetes
Nampt, also known as visfatin, was described as an adipokine found in visceral fat that acted as an insulin mimetic (Fukuhara et al. Science 307:426-30 (2007)). This paper was eventually retracted and other groups have failed to confirm that Nampt binds the insulin receptor. Nevertheless, many subsequent papers continue to report correlations between Nampt expression and obesity and/or diabetes. In one, increased expression of Nampt and levels of circulating Nampt were seen in obese patients (Catalan et al.; Nutr. Metab. Cardiovasc. Dis. (2010)), although a different study found that the correlation was specific only to obese patients with type 2 diabetes (Laudes, et al.; Horm. Metab. Res. (2010)). Yet another study reported a correlation between BMI and body fat mass and Nampt plasma levels, but an inverse correlation with cerebrospinal fluid levels of Nampt (Hallschmid et al.; Diabetes. 58(3):637-40 (2009)). Following bariatric surgery, patients with pronounced weight loss showed decreased levels of Nampt mRNA in liver (Moschen et al.; J. Hepatol. 51(4):765-77 (2009)). Finally, a rare single nucleotide polymorphism was identified in Nampt that correlated with severe obesity (Blakemore, et al.; Obesity 17(8):1549-53 (2009)). In contrast to these reports, Nampt levels were not altered in rat models of obesity (Mercader et al.; Horm. Metab. Res. 40(7):467-72 (2008)). Further, circulating levels of Nampt correlated with HDL-cholesterol and inversely with triglycerides (Wang et al.; Pflugers Arch. 454(6):971-6 2007)), arguing against Nampt involvement in obesity. Finally Nampt has been show to be a positive regulator of insulin secretion by beta-cells (Revollo et al. Cell Metab. 6(5):363-75 (2007)). This effect seems to require the enzymatic activity of Nampt and can be mimicked in cell culture models by exogenous addition of NaMN.
Because Nampt inhibition can decrease the activity of poly(ADP ribose) polymerases (PARPs) through the dependence of PARPs on NAD as a substrate, Nampt inhibitor, either alone or in combination with PARP inhibitors can be efficacious in any ailment treatable by PARP inhibitors. In this regard, PARP inhibitors have shown efficacy in models of type I diabetes (Drel et al. Endocrinology. 2009 December; 150(12):5273-83. Epub 2009 Oct. 23).
In view of the above, and despite the contrasting results mentioned, it is believed that inhibition of Nampt activity would be effective in treating obesity and diabetes, and other complications associated with these, and other, metabolic diseases and disorders. Consequently, the present invention provides methods of treating obesity and diabetes, and other complications associated with these, and other, metabolic diseases and disorders, by administering therapeutically effective amounts of one or more of the compounds of the present invention.
e. Treating T-Cell Mediated Autoimmune Disease
Nampt expression has been shown to be upregulated in activated T-cells (Rongavaux et al.; J. Immunol. 181(7):4685-95 2008)) and Phase I clinical trials report lymphopenia in patients treated with Nampt inhibitors (reviewed in von Heideman et al.; Cancer Chemother. Pharmacol. (2009)). Additionally, in a mouse model of a T-cell autoimmune disease, experimental autoimmune encephalomyelitis (EAE), Nampt inhibition reduced the clinical disease score and demyelination in the spinal cord (Bruzzone et al.; PLoS One. 4(11):e7897 (2009)).
In view of the above, it is believed that inhibition of Nampt activity would be effective in treating T-cell mediated autoimmune disease, and other complications associated with diseases and disorders. Consequently, the present invention provides methods of treating T-cell mediated autoimmune disease, and other complications associated with these diseases and disorders, by administering therapeutically effective amounts of one or more of the compounds of the present invention.
f. Treating Ischemia
Because Nampt inhibition can decrease the activity of poly(ADP ribose) polymerases (PARPs) through the dependence of PARPs on NAD as a substrate, Nampt inhibitor, either alone or in combination with PARP inhibitors can be efficacious in any ailment treatable by PARP inhibitors. The PARP inhibitor FR247304 has been shown to attenuate neuronal damage in vitro and in vivo models of cerebral ischemia (Iwashita, et al. J. Pharmacol Exp. Ther. 310(2):425-36 (2004). Epub 2004 Apr. 9). Similarly there are suggestions that PARP inhibitors could be efficacious in clinical management of chronic hypoperfusion-induced neurodegenerative diseases including ocular ischemic syndrome (Mester et al. Neurotox. Res. 16(1):68-76 (2009) Epub 2009 Apr. 9) or ischemia reperfusion (Crawford et al. Surgery. 2010 Feb. 2. [Epub ahead of print]).
In view of the above, it is believed that inhibition of Nampt activity would be effective in treating ischemia and other complications associated with this condition. Consequently, the present invention provides methods of treating ischemia and other complications associated with this condition, by administering therapeutically effective amounts of one or more of the compounds of the present invention, either alone, or in combination with a PARP inhibitor.
In an additional aspect, the present invention also provides methods for combination therapy for treating cancer, systemic or chronic inflammation, rheumatoid arthritis, diabetes, obesity, T-cell mediated autoimmune disease, ischemia, and other complications associated with these diseases and disorders, by treating a patient in need thereof, with a therapeutically effective amount of one of the compounds of the present invention together with a therapeutically effective amount of one or more other compounds that have been shown to be effective in the treatment of cancer, systemic or chronic inflammation, rheumatoid arthritis, diabetes, obesity, T-cell mediated autoimmune disease, ischemia, and other complications associated with these diseases and disorders.
In some embodiments, the present invention provides methods for combination therapy for treating cancer by treating a patient (either a human or another animal) in need of the treatment with one of the compounds of the present invention together with one or more other anti-cancer therapies. Such other anti-cancer therapies include traditional chemotherapy agents, targeted agents, radiation therapy, surgery, hormone therapy, immune adjuvants, etc. In the combination therapy, one of the compounds of the present invention, such as, for example, a compound of Formulae I, Ia, Ia1, Ia2, Ib, Ib1, Ib2, Ib3, Ic, Id, II, IIa, IIa1, IIa2, IIa3, IIa4, IIb, IIb1, IIb2, IIb3, IIb4, IIb5, IIb6, IIb7, IIc, IIc1, IId, IId1, III, IIIa, IIIa1, IIIa2, IIIa3, IIIa4, IIIa5, IIIa6, IIIb, IIIb1, IIIb2, IIIb3, IIIb4, IIIb5, IIIb6, IIIb7, IIIb8, IIIb9, IIIb10, IIIb11, IIIc, IV, IVa, IVa1, IVa2, Iva3, IVa4, IVa5, IVa6, IVb, IVb1, IVb2, IVb3, IVb4, IVb5, IVb6, IVb7, IVb8, and IVc, as illustrated herein, and a compound of Tables 1A and 1B, 2, 3A and 3B, 4, 5, and 6, can be administered separately from, or together with the one or more other anti-cancer therapies.
Specifically, Nampt inhibition has been shown to sensitize cells to the effects of various chemotherapeutic or cytotoxic agents. Specifically, Nampt inhibition has been shown to sensitize cells to amiloride, mitomycin C, N-methyl-N′-nitro-N-nitrosoguanidine (MNNG), melphalan, daunorubicin, cytarabine (Ara-C), and etoposide (Ekelund, S. et al. Chemotherapy 48:196-204 (2002); Rongvaux, A. et al. The Journal of Immunology 181(7):4685-95 (2008); Martinsson, P. et al. British Journal of Pharmacology 137:568-73 (2002); Pogrebniak, A. et al. European Journal of Medical Research 11(8):313-21 (2006)). It is also thought that lactate dehydrogenase A inhibitors, prostaglandin H2 synthase 2 (PGHS-2) inhibitors, combined with Nampt inhibitors would be effective cancer treatments. Although the mechanism(s) behind this synergy between Nampt inhibitors and other cell killing agents has not been fully explored, Nampt inhibition causes a drop in cellular levels of NAD+ at doses and times of exposure that are not overtly toxic to the cell. Without wishing to be bound by theory, it is believed that sub-lethal NAD+ drops render cells vulnerable to other cytotoxic agents, and particularly to compounds which activate the DNA repair enzyme poly(ADP-ribose) polymerase (PARP), since PARP requires NAD+ as a substrate and consumes NAD+ during its enzymatic action (
Accordingly, in some embodiments, the present invention provides the methods of treating cancer disclosed herein further comprise administering a therapeutically-effective amount of a PARP activator to the patient in addition to administering a compound of the present invention, such as, for example, a compound of Formulae I, Ia, Ia1, Ia2, Ib, Ib1, Ib2, Ib3, Ic, Id, II, IIa, IIa1, IIa2, IIa3, IIa4, IIb, IIb1, IIb2, IIb3, IIb4, IIb5, IIb6, IIb7, IIc, IIc1, IId, IId1, III, IIIa, IIIa1, IIIa2, IIIa3, IIIa4, IIIa5, IIIa6, IIIb, IIIb1, IIIb2, IIIb3, IIIb4, IIIb5, IIIb6, IIIb7, IIIb8, IIIb9, IIIb10, IIIb11, IIIc, IV, IVa, IVa1, IVa2, Iva3, IVa4, IVa5, IVa6, IVb, IVb1, IVb2, IVb3, IVb4, IVb5, IVb6, IVb7, IVb8, and IVc, as illustrated herein, and a compound of Tables 1A and 1B, 2, 3A and 3B, 4, 5, and 6.
Additionally, in some of such embodiments, the cells of the cancer have functional homologous recombination (HR) systems. Also, in some of such embodiments, the methods further comprise identifying the cells of the cancer as having functional HR systems. Methods of performing such identification are known in the art. Furthermore, in addition to a PARP activator, in some embodiments, the methods of treating cancer disclosed herein further comprise administering a therapeutically effective amount of a non-DNA damaging agent to the patient, wherein the non-DNA damaging agent is not a PARP activator and not a compound of the present invention. For example, where the cancer has functional HR systems for repairing DNA damage, then an additional chemotherapeutic could be administered that does not rely on DNA damage for efficacy. Chemotherapeutics the do not damage DNA are known in the art.
Agents or treatments that may be capable of activating the PARP enzyme include but are not limited to: alkylating agents (methyl methane sulfonate (MMS), N-methyl-N′nitro-N-nitrosoguanidine (MNNG), Nitrosoureas (N-methyl-N-nitrosourea (MNU), streptozotocin, carmustine, lomustine), Nitrogen mustards (melphalan, cyclophosphamide, uramustine, ifosfamide, clorambucil, mechlorethamine), alkyl sulfonates (busulfan), platins (cisplatin, oxaliplatin, carboplatin, nedaplatin, satraplatin, triplatin tetranitrate), non-classical DNA alkylating agents (temozolomide, dacarbazine, mitozolamide, procarbazine, altretamine)), radiation (X-rays, gamma rays, charged particles, UV, systemic or targeted radioisotope therapy), and other DNA damaging agents such as: topoisomerase inhibitors (camptothecin, beta-lapachone, irinotecan, etoposide), anthracyclines (doxorubicin, daunorubicin, epirubicin, idarubicin, valrubicin, mitoxantrone), reactive oxygen generators (menadione, peroxynitrite), and anti-metabolites (5-FU, raltetrexed, pemetrexed, pralatrexate, methotrexate, gemcitabine, thioguanine, fludarabine, azathioprine, cytosine arabinoside, mercaptopurine, pentostatin, cladribine, folic acid, floxuridine).
It is further believed that tumors or tumor cell lines treated with compounds that directly or indirectly inhibit the enzyme thymidylate synthase (TS) can also be more susceptible to Nampt inhibitors, such as compounds of the present invention.
Accordingly, in some embodiments, the present invention provides the methods of treating cancer disclosed herein further comprise administering a therapeutically-effective amount of a thymidylate synthase inhibitor to the patient in addition to administering a compound of the present invention, such as, for example, a compound of Formulae I, Ia, Ia1, Ia2, Ib, Ib1, Ib2, Ib3, Ic, Id, II, IIa, IIa1, IIa2, IIa3, IIa4, IIb, IIb1, IIb2, IIb3, IIb4, IIb5, IIb6, IIb7, IIc, IIc1, IId, IId1, III, IIIa, IIIa1, IIIa2, IIIa3, IIIa4, IIIa5, IIIa6, IIIb, IIIb1, IIIb2, IIIb3, IIIb4, IIIb5, IIIb6, IIIb7, IIIb8, IIIb9, IIIb10, IIIb11, IIIc, IV, IVa, IVa1, IVa2, Iva3, IVa4, IVa5, IVa6, IVb, IVb1, IVb2, IVb3, IVb4, IVb5, IVb6, IVb7, IVb8, and IVc, as illustrated herein, and a compound of Tables 1A and 1B, 2, 3A and 3B, 4, 5, and 6.
In some embodiments, the thymidylate synthase inhibitor directly or indirectly inhibits thymidylate synthase. Thymidylate synthase inhibitors include 5-FU, raltitrexed, pemetrexed, and other TS inhibitors developed over the past decades.
It is further believed that agents that promote aberrant uracil incorporation into DNA can also make subjects being administered such agents more susceptible to Nampt inhibitors, such as compounds of the present invention. Any inhibitor of thymidylate synthase (TS) would cause uracil incorporation into DNA. Other agents, such as inhibitors of dihydrofolate reductase (e.g. methotrexate) have also been shown to cause uracil to aberrantly incorporate into DNA.
Accordingly, in some embodiments, the present invention provides the methods of treating cancer disclosed herein further comprise administering a therapeutically-effective amount of agents that promote aberrant uracil incorporation into DNA, to the patient in addition to administering a compound of the present invention, such as, for example, a compound of Formulae I, Ia, Ia1, Ia2, Ib, Ib1, Ib2, Ib3, Ic, Id, II, IIa, IIa1, IIa2, IIa3, IIa4, IIb, IIb1, IIb2, IIb3, IIb4, IIb5, IIb6, IIb7, IIc, IIc1, IId, IId1, III, IIIa, IIIa1, IIIa2, IIIa3, IIIa4, IIIa5, IIIa6, IIIb, IIIb1, IIIb2, IIIb3, IIIb4, IIIb5, IIIb6, IIIb7, IIIb8, IIIb9, IIIb10, IIIb11, IIIc, IV, IVa, IVa1, IVa2, Iva3, IVa4, IVa5, IVa6, IVb, IVb1, IVb2, IVb3, IVb4, IVb5, IVb6, IVb7, IVb8, and IVc, as illustrated herein, and a compound of Tables 1A and 1B, 2, 3A and 3B, 4, 5, and 6.
In view of the above, some embodiments of the present invention comprises the use of the compounds of the present invention with a second chemotherapeutic agent that has been discovered to work synergistically with one or more of the compounds of the present invention, such as compounds or treatments that activate PARP, induce DNA damage, inhibit TS, and/or promote aberrant uracil incorporation into DNA, or inhibit proteasomes or specific kinases.
In certain embodiments of this aspect of the invention, the second chemotherapeutic agent is selected from, at least, methyl methanesulfonate (MMS), mechlorethamine, streptozotocin, 5-fluorouracil (5-FU), raltitrexed, methotrexate, bortezomib, PI-103, and dasatinib.
In HCT116 cells, the potent and selective PARP inhibitor olaparib failed to synergize with Nampt inhibitors—in fact antagonism was observed, in which olaparib protected cells somewhat from Nampt inhibitor-induced death. PARP inhibitors are relatively benign to cells (like HCT116 cells) that have a functional homologous recombination (HR) system to repair double stranded DNA damage (Ashworth A. Journal of Clinical Oncology 26(22):3785-90 (2008)). In fact, the model (
Other routes of HR deficiency in oncogenesis (other than BRCA sequence mutation) could also lead to sensitivity to PARP inhibition plus Nampt inhibitor combination therapy. These additional mutations, which lead to a “BRCAness” phenotype, include, as documented in ovarian cancers, BRCA1 promoter methylation and upregulation of BRCA inhibitors, such as the protein EMSY (Bast R. C. and Mills G. B. Journal of Clinical Oncology 28(22):3545-8 (2010)). Further studies have demonstrated that mutation of the tumor suppressor gene phosphatase and tensin homolog (PTEN), a gene frequently mutated in a variety of cancers, reduces HR function and sensitizes cells to PARP inhibitors (Mendes-Pereira A. M. et al. EMBO Molecular Medicine 1:315-322 (2009)). Providing more evidence for the BRCAness model of PARP inhibitor sensitivity, in a cell biological study using RNA interference, mutation of any of 12 different genes functionally important for HR sensitized cells to PARP inhibitors (McCabe et al. Cancer Research 66(16): 8109-15 (2006)). Finally, a recent paper has demonstrated that cells in hypoxic conditions, such as those found in the center of virtually all solid tumors, are selectively killed by PARP inhibitors (Chan et al. Cancer Research 70(2): 8045-54 (2010)).
Accordingly, in some embodiments, the present invention provides the methods of treating cancer disclosed herein further comprise administering a therapeutically-effective amount of a PARP inhibitor to the patient in addition to administering a compound of the present invention, such as, for example, a compound of Formulae I, Ia, Ia1, Ia2, Ib, Ib1, Ib2, Ib3, Ic, Id, II, IIa, IIa1, IIa2, IIa3, IIa4, IIb, IIb1, IIb2, IIb3, IIb4, IIb5, IIb6, IIb7, IIc, IIc1, IId, IId1, III, IIIa, IIIa1, IIIa2, IIIa3, IIIa4, IIIa5, IIIa6, IIIb, IIIb1, IIIb2, IIIb3, IIIb4, IIIb5, IIIb6, IIIb7, IIIb8, IIIb9, IIIb10, IIIb11, IIIc, IV, IVa, IVa1, IVa2, Iva3, IVa4, IVa5, IVa6, IVb, IVb1, IVb2, IVb3, IVb4, IVb5, IVb6, IVb7, IVb8, and IVc, as illustrated herein, and a compound of Tables 1A and 1B, 2, 3A and 3B, 4, 5, and 6.
In some of such embodiments, the cells of the cancer do not have functional homologous recombination (HR) systems. In some of such embodiments, the methods of treating cancer further comprise identifying the cells of the cancer as not having functional HR systems. Methods of performing such identification are known in the art.
In some of such embodiments, the PARP inhibitor is olaparib, AG014699/PF-01367338, INO-1001, ABT-888, Iniparib, BSI-410, CEP-9722, MK4827, or E7016.
In some of such embodiments, the methods further comprise administering a therapeutically effective amount of a DNA damaging agent to the patient, wherein the DNA damaging agent is other than a PARP inhibitor. DNA damaging agents are known in the art and include topoisomerase inhibitors (camptothecin, beta-lapachone, irinotecan, etoposide), anthracyclines (doxorubicin, daunorubicin, epirubicin, idarubicin, valrubicin, mitoxantrone), reactive oxygen generators (menadione, peroxynitrite), and anti-metabolites (5-FU, raltetrexed, pemetrexed, pralatrexate, methotrexate, gemcitabine, thioguanine, fludarabine, azathioprine, cytosine arabinoside, mercaptopurine, pentostatin, cladribine, folic acid, floxuridine).
Studies were expanded to investigate synergistic combinations of Nampt inhibitors and standards of care in particular cancer types. Cancer cell lines used in these studies represented cancer types found to be sensitive to Nampt inhibition [e.g. non-Hodgkins lymphoma, multiple myeloma, glioma, non-small cell lung carcinoma (NSCLC), small cell lung carcinoma (SCLC), ovarian cancer and colorectal cancer]. Standards of care in these cancer types tested in synergy experiments included: 4-HC (the pre-activated form of cyclophosphamide), doxorubicin, vincristine, prednisolone, dexamethasone, melphalan, thalidomide, bortezomib, temozolomide, cisplatin, paclitaxel, gefitinib, 5-FU, oxaliplatin, irinotecan, and etoposide. Synergistic cytotoxicity was found when compounds of the present invention were combined with 4HC in small-cell lung cancer (SCLC) and glioma, temozolomide in glioma, and 5-FU in colon cancer.
Another specific example of an active agent with which the compounds of the present invention can be co-administered is the immune adjuvant L-1-methyl tryptophan (L-1MT). In studies of co-administration of L-1MT with another inhibitor of Nampt (i.e., AP0866 [also known as FK866 or WK175]), the combination was shown to provide an additive inhibitory effect on tumor growth of murine gastric and bladder tumors in immune-competent mice (Yang et al. Exp. Biol. Med. 235:869-76 (2010)).

The beads were washed three times with 20 volumes of binding buffer, 2× with 20 volumes wash buffer (150 mM NaCl, 50 mM Hepes [pH 7.4], 1% Tween 20, 1 mM EDTA, 2 mM dithiothrietol) and finally twice with 10 volumes of 150 mM NaCl, 50 mM Hepes [pH 7.4].
During the final wash, an aliquot containing 101 of beads was transferred to a separate tube and resuspended with 15 μl of 2×SDS/PAGE loading buffer (Invitrogen Corporation, Carlsbad, Calif.) for 5 minutes at 90° C. The eluted proteins were resolved by electrophoresis on a NuPage 4-12% Bis-Tris Gel (Invitrogen Corporation, Carlsbad, Calif.) and visualized by staining with Ruby Red (Invitrogen Corporation, Carlsbad, Calif.). The remaining beads (40 μl) were processed for analysis by mass spectrometry.
This assay was used to confirm the selectivity of a subset of the compounds of the present invention for targeting Nampt.
Bound proteins were digested by treating the beads with trypsin as follows. After the final wash, beads were resuspended in an equal volume of trypsin digest buffer (50 mM ammonium bicarbonate, (pH 8.0), 5% acetonitrile, 1 mM calcium chloride). Samples were reduced with 5 mM DTT at 65° C. for 15 minutes and alkylated with 10 mM iodoacetamide in the dark at 30° C. for 30 minutes. Sequencing grade modified trypsin (Promega Corporation, Madison, Wis.) was added and samples digested for 1.5 hours at 37° C.
For one dimensional LC-MS/MS, 5 μl aliquots (approximately 1/10 of sample) were loaded by NanoLC-AS1 autosampler (Eksigent, Dublin, Calif.) and NanoLC-2D (Eksigent, Dublin, Calif.) in 0.1% formic acid in 5% acetonitrile onto an OPTI-PAK C18 trap column (Optimize Technologies, Oregon City, Oreg.). Peptides were eluted from the trap and separated on a flame-pulled 10 cm×75 μM i.d. fused-silica capillary column (Polymicro Technologies, Phoenix, Ariz.) self-packed with Synergy Hydro C18 media (Phenomenex, Torrence, Calif.). The following gradient was used: 5-15% B (0.1% formic acid in acetonitrile) in 5 minutes, 15-40% B in 60 minutes, 40-60% B in 5 minutes, 80-80% B for 10 minutes, and 5-5% B for 10 minutes. Eluted peptides were ionized directly into the LTQ-Orbitrap (Thermo Fisher Scientific, Inc., Waltham, Mass.). A full scan from m/z 300-2000 was performed in the Orbitrap at a resolution of 60,000. The top five most intense ions were selected for MS2 in the LTQ (Full FT-Big 5 IT), with a normalized collision energy of 35%.
Peptides and proteins were identified by searching the raw mass spectrometry data against a combined forward and reverse human RefSeq database. The Sequest algorithm was used with the following parameters: peptide mass tolerance=10 ppm, fragment ion tolerance=1.0 kD, 2 missed cleavages allowed, differential modification of Methionine oxidation (15.994915), 3 possible modifications per peptide, and a constant cysteine modification of 57.0215. After filtering, proteins that had a protein probability greater than 10−3 using Bioworks 3.0 software (Thermo Fisher Scientific, Inc., Waltham, Mass.) were identified. There was a false discovery rate of less than 0.5%. Hierarcheral clustering was done using the Bigcat software package (McAfee, K. J., et al. Mol. Cell. Proteomics. 5, 1497-1513 (2006)).
5-phosphoribosyl-1-pyrophosphate (PRPP), ATP, NaM, NaMN, Triton X-100, UDP-glucose and diaphorase were purchased from Sigma-Aldrich, St. Louis, Mo. Human NAMPT, NMN adenylyltransferase (NMNAT1) and UDP-glucose dehydrogenase (UGDH) encoding DNAs were each inserted into a house-modified E. Coli expression vector such that the expressed proteins carried an N-terminal 6×His tag. The His-tagged proteins were expressed in the BL21-AI E. Coli expression strain (Invitrogen Corporation, Carlsbad, Calif.) following induction by 0.2% L-arabinose and 0.5 mM IPTG at 30° C. Proteins were purified on Ni-NTA resin (Qiagen, Germantown, Md.).
The assay for Nampt catalytic activity was constructed based on a previously published coupled enzyme fluorometric technique, which employs NADH as ultimate analyte (Revollo, J. R. et al. Biol. Chem. 279, 50754-50763 (2004)). A substantial improvement in assay sensitivity was achieved by switching from direct detection to a resazurin/diaphorase-based fluorometric detection system for NADH (Guilbault, G. G., and Kramer, D. N. Anal. Chem. 37, 1219-1221 (1965)). The standard inhibition analyses were performed in a real-time mode in 96-well microtiter plates using 50 mM Tris-HCl, pH 7.5, 1% DMSO (v/v), 0.01% Triton X-100 (v/v), 10 mM MgCl2, 2 mM ATP, 3 M NAM, 8 M PRPP, 50 μM Nampt, as well as the following detection reagents: 5 nM Nmnat, 200 nM Ugdh, 200 M UDP-glucose, 0.02 U/mL diaphorase and 0.25 M resazurin. Incubation of samples at room temperature for up to 3 hours was followed by quantification of fluorescence intensities at excitation and emission wavelengths of 510 nm and 590 nm, respectively, using Gemini XS plate reader (Molecular Devices, Sunnyvale, Calif.). The counter-assay intended to disqualify false positives, such as inhibitors of detection enzymes or fluorescence quenchers, was carried out essentially as described above with an exception that 1 μM NaMN was substituted for Nampt. A preparation of catalytically inactive Nampt-D313A mutant enzyme was used as a negative control for assay development.
All of the compounds of Tables 1A and 1B, 2, 3A and 3B, 4, 5, and 6 were tested using this assay. For example, example compound number 152 exhibited an vitro IC50 of about 2.0 nM, example compound number 164 exhibited an vitro IC50 of about 1.8 nM, example compound number 210 exhibited an vitro IC50 of about 6.3 nM, example compound number 363 exhibited an vitro IC50 of about 3.4 nM, example compound number 580 exhibited an vitro IC50 of about 0.8 nM, example compound number 605 exhibited an vitro IC50 of about 2.4 nM, example compound number 613 exhibited an vitro IC50 of about 11 nM, example compound number 634 exhibited an vitro IC50 of about 520 nM, example compound number 641 exhibited an vitro IC50 of about 1.3 μM, example compound number 831 exhibited an vitro IC50 of about 10 nM, and example compound number 797 exhibited an vitro IC50 of about 10 nM.
NAD+ in cells was measured by modification of existing protocols (Lee, H. I., et al. Exp. Mol. Med. 40, 246-253 (2008)). MCF-10A cells stably transduced with the PIK3CA(H1047R) oncogene were seeded in 96 well plates at very high density (100% confluence) and allowed to settle overnight. Test compound dissolved in DMSO was added and drug incubation proceeded for 20-24 hours. Cells were washed with PBS and harvested by incubation in 25 L 0.5 M perchloric acid (HClO4) followed by vigorous shaking at 4° C. for 15 minutes. Acidic cell lysates were neutralized by adding 8 μL of 2 M KOH/0.2 M K2HPO4. The entire lysate volume was transferred to a centrifuge plate and spun at 3000 rpm in a table top centrifuge (4° C.) for 5 minutes to clear the precipitate. Lysate was assayed for both NAD+ and ATP. For NAD+ measurement, 10 L lysate from the centrifuged plate was added to 90 L of reaction solution in Costar 96 half-well plates (Corning, Corning, N.Y.). The final concentration of the reaction mixture was 120 M Tris-HCl, pH 7.5, 0.01% Triton X-100, 35 M UDP-Glucose, 50 nM UGDH, 0.5 M resazurin, and 0.1 unit/mL Diaphorase. Reactions were allowed to proceed for 1 hour at room temperature, after which time fluorescence was read on a Gemini plate reader as described above. For ATP measurement, 5 μL of cleared lysate was added to 195 μL PBS. 50 μL CellTiter-Glo reagent (Promega Corporation, Madison, Wis.) was added and ATP measured as described in the cytotoxicity assay methods.
To measure Poly (ADP-Ribose) Polymerase (PARP) activity, an imaging-based cellular assay was developed. MCF-10A cells stably transduced with the PIK3CA(H1047R) oncogene were seeded in 96 well plates and allowed to settle overnight. Test compound dissolved in DMSO was added and drug incubation proceeded for 20-24 hours. Under these conditions, Nampt inhibitors showed no evidence of toxicity. The next morning, hydrogen peroxide was added to the cells to a final concentration of 500 μM. After 8 minutes of hydrogen peroxide treatment, cells were fixed in 100%, −20° C. methanol. After re-hydrating and washing with PBS, cells were incubated in blocking buffer (HBSS, 1% BSA, 0.1% Tween20), and were then stained overnight with an anti-PAR mouse monoclonal antibody (Trevigen, Gaithersburg, Md.; 1:2000 dilution in blocking buffer). Cells were washed with PBS and incubated with 1:1000 of anti-mouse-Alexa488 (Invitrogen Corporation, Carlsbad, Calif.), 5 μg/mL Hoechst 33342 (Invitrogen), and 0.1 μg/mL HCS CellMask deep red (Invitrogen). Cells were washed with PBS and then stored in blocking buffer).
Images were acquired on a Pathway 855 instrument (BD Biosciences, San Jose, Calif.) using a 10× objective. Using Attovision software (BD Biosciences, San Jose, Calif.), the Hoechst signal was used to segment nuclei and the PAR signal for each nuclei in a well was subsequently averaged to generate a single value. After background subtraction using samples that were not incubated with the anti-PAR primary antibody, PAR intensity per well was graphed (Prism; GraphPad Software, Inc.; La Jolla, Calif.).
Cell lines were treated with a fixed dose of Exemplary Compound A and screened for NA rescue and Naprt1 expression by immunoblotting and quantitative RT-PCR (Table 7). Of 176 cell lines tested, 47 did not rescue, 16 partially rescued and 113 completely rescued. The 176 cell lines included 5 normal (non-cancerous) cells and 3 primary cells (italicized in the table), all of which rescued. Naprt1 was quantified by western blotting and q-RT-PCR in 164 and 123 of the 176 cell lines, respectively. Naprt1 levels were low or undetectable in cell lines that did not rescue. A statistically significant (p value <0.0001) correlation existed between NA rescue phenotype and Naprt1 protein or mRNA expression levels.
For quantification by western blot, human tumor cell proteins were prepared from frozen cell pellets. Cell pellets were thawed and lysed in 0.5% Triton X-100, 50 mM HEPES [pH 7.4], 150 mM NaCl, 1 mM EDTA, 10% glycerol, and 1 mM DTT for 30 minutes at 4° C. After centrifugation to remove cellular debris, protein concentration was determined using the BCA (Sigma BCA1-1KT) or CBQCA protein assay kits (Molecular Probes #C-6667). Ruby Red staining of SDS-PAGE gels was used to confirm protein loading.
For immunoblot detection, equivalent protein amounts were resolved by electrophoresis and transferred to nitrocellulose membrane. Membranes were blocked in Starting Block T20 (TBS) (Thermo Scientific #37543) and were probed with anti-Naprt (Proteintech Group 13549-1-AP or anti-Gapdh (Calbiochem #CB1001) antibodies. HRP-conjugated secondary antibodies (Santa Cruz Biotechnology) and Super Signal West Dura Extended Duration Substrate (Thermo Scientific #34075) were used for detection. Protein signals were quantified by imaging using an EC3 imaging system (UVP Bioimaging Systems) and VisionWorksSL software. The dynamic range of signal detection was enhanced by utilizing multiple exposure times. Naprt protein levels were calculated as a percentage of the cognate signal detected in the HCT 116 cell lysate.
For quantification by qRT-PCR, Untreated cell pellets were collected lysed in RLT buffer with 1% β-Mercaptoethanol. RNA was isolated using an RNeasy spin column kit (Qiagen 74104), loaded in triplicate to a 96-well plate at 11 ng total RNA/well, and probed for NAPRT1 with the TaqMan primer set Hs00292993_ml, using the QuantiTect probe RT-PCR kit (Qiagen 204443), with a final sample volume of 25 ul/well. Relative NAPRT expression was assayed on the Applied Biosystems 7300 Real-Time PCR system thermal cycler. The plate was heated to 50° C. for 30 minutes, followed by 95° C. for 15 minutes, followed by 40 cycles alternating between 95° C. for 15 seconds and 60° C. for 1 minute. Data was collected during the 60° C. step of each cycle, and cycle threshold values were interpolated onto a dilution curve of total RNA from the cell line SK-BR-3 to give relative values of the initial NAPRT mRNA concentration for each sample. The average RNA concentration for each cell line was then presented relative to the expression seen in the cell line SK− BR-3 as a percentage.
Additional cancer cell lines were treated with Exemplary Compounds A, C, D, E, F, G and H (identified below) (Table 8). The NA rescue phenotype of a particular cancer cell line was maintained for all Nampt inhibitors tested.
As noted above, Nampt inhibition has been shown to sensitize cells to the effects of various chemotherapeutic or cytotoxic agents. Specifically, Nampt inhibition has been shown to sensitize cells to amiloride, mitomycin C, N-methyl-N′-nitro-N-nitrosoguanidine (MNNG), melphalan, daunorubicin, cytarabine (Ara-C), etoposide, and the lactate dehydrogenase inhibitor FX11 (Ekelund, S. et al. Chemotherapy 48:196-204 (2002); Rongvaux, A. et al. The Journal of Immunology 181(7):4685-95 (2008); Martinsson, P. et al. British Journal of Pharmacology 137:568-73 (2002); Pogrebniak, A. et al. European Journal of Medical Research 11(8):313-21 (2006) Le, et al., Proceedings of the National Academia of Sciences 107(5):2037-2042 (2010)). Although the mechanism(s) behind this synergy between Nampt inhibitors and other cell killing agents has not been fully explored, Nampt inhibition causes a drop in cellular levels of NAD+ at doses and times of exposure that are not overtly toxic to the cell. In the case of HCT116 cells, it has been discovered that there is a “6% threshold,” in which cell death does not occur until NAD+ levels drop to approximately 6% of normal levels. Without wishing to be bound by theory, it was hypothesized that these sub-lethal NAD+ drops will render a cell vulnerable to other cytotoxic agents, and particularly to compounds which activate the DNA repair enzyme poly(ADP-ribose) polymerase (PARP), since PARP requires NAD+ as a substrate and consumes NAD+ during its enzymatic action (Kim, M. Y. et al. Genes & Development 19:1951-67 (2005);
This hypothesis was tested by determining the drug interaction (synergy, additivity, or antagonism) of 19 different cytotoxic or chemotherapeutic compounds of various categories, along with a known Nampt inhibitor, as a positive control. Nineteen chemotherapeutic compounds were chosen based upon their clinical relevance and their likelihood of synergizing with Nampt inhibitors based upon the PARP model (
Of the 19 various chemotherapeutic compounds tested, 9 displayed reproducible and quantitatively significant synergy with a known Nampt inhibitor. The compounds showing synergy included the DNA alkylating agents methyl methanesulfonate (MMS), mechlorethamine, and streptozotocin (a therapy for pancreatic cancer). Some alkylating agents can synergize with Nampt inhibitors due to their ability to activate PARP and depress NAD+ levels in cells (Miwa, M. and Masutani, M. Cancer Science 98(10):1528-35 (2007); Kim, M. Y. et al. Genes & Development 19:1951-67 (2005)). Somewhat unexpectedly, three clinically relevant drugs involved in nucleotide synthesis (i.e., 5-fluorouracil (5-FU), raltitrexed, and methotrexate) also synergized with the Nampt inhibitor. While the locus of action of each of these three drugs is different, all either directly or indirectly inhibit the enzyme thymidylate synthase (TS). TS inactivation is know to cause an imbalance in nucleotide pools that subsequently promotes aberrant uracil incorporation into DNA (Berger S. H. et al. Biochemical Pharmacology 76:697-706 (2008)). The mechanism of synergy between 5-FU and Nampt inhibitors was investigated and it was discovered that 5-FU in HCT116 cells was a PARP activator, and that activation of PARP was essential for the synergy between 5-FU and Nampt inhibitors (
The initial experiments demonstrated that 5-FU and Nampt inhibitors did not synergize in all cells tested, and in these cells lacking synergy, 5-FU did not cause detectable PARP activation. These results suggested that uracil incorporation into DNA either does not occur in all cells treated with 5-FU, or that PARP is only activated in certain cells in response to uracil incorporation into DNA. The observation of cell-specific synergy between 5-FU and Nampt inhibitors could be therapeutically useful as a mechanism of expanding therapeutic window. Of further note, it is believed the relationship uncovered between 5-FU, PARP activation, and Nampt inhibition is a new discovery.
Finally, it was observed that the proteosome inhibitor bortezomib, the PI3K/mTOR inhibitor PI-103, and the tyrosine kinase inhibitor dasatinib all synergized with the Nampt inhibitor. The synergy of these three compounds with the Nampt inhibitor was unexpected.
In HCT116 cells, the potent and selective PARP inhibitor olaparib failed to synergize with Nampt inhibitors—in fact antagonism was observed, in which olaparib protected cells somewhat from Nampt inhibitor-induced death. This was not fully unexpected, as PARP inhibitors are relatively benign to cells (like HCT116 cells) that have a functional homologous recombination (HR) system to repair double stranded DNA damage (Ashworth A. Journal of Clinical Oncology 26(22):3785-90 (2008)). In fact, the model (
These studies were expanded to investigate synergistic combinations of Nampt inhibitors and standards of care in particular cancer types. Cancer cell lines used in these studies represented cancer types found to be sensitive to Nampt inhibition [e.g. non-Hodgkins lymphoma, multiple myeloma, glioma, non-small cell lung carcinoma (NSCLC), small cell lung carcinoma (SCLC), ovarian cancer and colorectal cancer]. Standards of care in these cancer types tested in synergy experiments included: 4-HC (the pre-activated form of cyclophosphamide), doxorubicin, vincristine, prednisolone, dexamethasone, melphalan, thalidomide, bortezomib, temozolomide, cisplatin, paclitaxel, gefitinib, 5-FU, oxaliplatin, irinotecan, and etoposide. Synergistic cytotoxicity was found when Nampt inhibitors (Exemplary Compound A and Exemplary Compound C, both identified hereinafter) were combined with 4HC in small-cell lung cancer (SCLC) and glioma, temozolomide in glioma, and 5-FU in colon cancer.
Nampt is most active in adipose tissue, liver, kidney, immune cells, and intestine (Bogan, K. L and Brenner, C. Nicotinic acid, nicotinamide, and nicotinamide riboside: a molecular evaluation of NAD+ precursor vitamins in human nutrition. Annu Rev Nutr. 28:115-305 (2008); and Revollo J R, et al. Nampt/PBEF/Visfatin regulates insulin secretion in beta cells as a systemic NAD biosynthetic enzyme. Cell Metab. November; 6(5):363-75 (2007)). Nevertheless, we sought to find out whether cancer cell lines of other origins are sensitive to Nampt inhibition.
Exponentially growing cells were plated in fresh growth media in a 96-well black, flat, clear-bottomed polystyrene microtiter plate (Packard View Plate 6005182). Twenty-four hours later, compounds were added from serial dilutions prepared in DMSO from 50 mM DMSO stock solutions. Each concentration of inhibitor was tested in duplicate at a final DMSO concentration of 0.4%. After 72 or 96 hours incubation, cell viability was quantified by measuring intracellular ATP levels using CellTiter-Glo (Promega). Luminescence data was collected on a TopCount NXT plate reader (PerkinElmer). Experimental values were normalized to solvent controls and plotted versus compound concentration to determine the concentration required for a 50% reduction in cell viability.
Using the Cytotoxicity Assay outlined above, several exemplary compounds of the present invention (“Exemplary Compounds A, B, C, D, E, F, G, and H), and a known Nampt inhibitor (“Control Nampt Inhibitor”) were tested and the results are shown in Tables 9A and 9B. Exemplary Compound A is a compound represented by Formula IIIb7. Exemplary Compounds B and I are compounds represented by Formula IIIb5. Exemplary Compounds C, D, and H are compounds represented by Formula IIIb9. Exemplary Compound E, F, and G are compounds represented by Formula IIIb8. Killing was nearly complete (>80%) with all three compounds after 3 days, and was complete in all lines after 7 days. These data demonstrate that a wide variety of cancer cell types are susceptible to killing by the compounds of the present invention. Units are TC50 (“Toxic Concentration required to cause 50% growth inhibition”) in nanoMolar (nM).
