Definitions

  • Restoration of appropriate nuclear localization of functional p53 protein can normalize some properties of neoplastic cells (Cai et al, 2008; Hoshino et al 2008; Lain et al 1999a; Lain et al 1999b; Smart et al 1999), can restore sensitivity of cancer cells to DNA damaging agents (Cai et al, 2008), and can lead to regression of established tumors (Sharpless & DePinho 2007, Xue et al, 2007). Similar data have been obtained for other tumor suppressor proteins such as forkhead (Turner and Sullivan 2008) and c-Abl (Vignari and Wang 2001).
  • CRM1 inhibition may provide particularly interesting utility in familial cancer syndromes (e.g., Li-Fraumeni Syndrome due to loss of one p53 allele, BRCA1 or 2 cancer syndromes), where specific tumor suppressor proteins (TSP) are deleted or dysfunctional and where increasing TSP levels by systemic (or local) administration of CRM1 inhibitors could help restore normal tumor suppressor function.
  • familial cancer syndromes e.g., Li-Fraumeni Syndrome due to loss of one p53 allele, BRCA1 or 2 cancer syndromes
  • TSP tumor suppressor proteins
  • RNAs are carried into and out of the nucleus by specialized transport molecules, which are classified as importins if they transport molecules into the nucleus, and exportins if they transport molecules out of the nucleus (Terry et al, 2007; Sorokin et al 2007). Proteins that are transported into or out of the nucleus contain nuclear import/localization (NLS) or export (NES) sequences that allow them to interact with the relevant transporters. Chromosomal Region Maintenance 1 (Crml), which is also called exportin-1 or Xpol , is a major exportin.
  • Nrml Chromosomal Region Maintenance 1
  • Crml blocks the exodus of tumor suppressor proteins and/or growth regulators such as p53, c-Abl, p21, p27, pRB, BRCA1 , IkB, ICp27, E2F4, KLF5, YAP1, ZAP, KLF5, HDAC4, FID AC 5 or forkhead proteins (e.g. FOX03a) from the nucleus that are associated with gene expression, cell proliferation, angiogenesis and epigenetics.
  • Crml inhibitors have been shown to induce apoptosis in cancer cells even in the presence of activating oncogenic or growth stimulating signals, while sparing normal (untransformed) cells.
  • LMB Crml inhibitor Leptomycin B
  • Crml In addition to tumor suppressor proteins, Crml also exports several key proteins that are involved in many inflammatory processes. These include IkB, NF-kB, Cox-2, RXRa, Commdl, HIFl , HMGBl, FOXO, FOXP and others.
  • IkB protein inhibitor of NF-kB
  • a protein inhibitor of NF-kB binds to NF-kB in the nucleus and the complex IkB-NF-kB renders the NF-kB transcriptional function inactive.
  • IkB dissociates from the IkB-NF-kB complex, which releases NF-kB and unmasks its potent transcriptional activity.
  • Many signals that activate NF-kB do so by targeting IkB for proteolysis (Phosphorylation of IkB renders it "marked” for ubiquitination and then proteolysis).
  • the nuclear IkBa-NF-kB complex can be exported to the cytoplasm by Crml where it dissociates and NF-kB can be reactivated. Ubiquitinated IkB may also dissociate from the NF-kB complex, restoring NF-kB transcriptional activity. Inhibition of Crml induced export in human neutrophils and macrophage like cells (U937) by LMB not only results in accumulation of transcriptionally inactive, nuclear IkBa-NF-kB complex but also prevents the initial activation of NF-kB even upon cell stimulation (Ghosh 2008, Huang 2000).
  • COMMDl is another nuclear inhibitor of both NF-kB and hypoxia- inducible factor 1 (HIFl) transcriptional activity. Blocking the nuclear export of COMMDl by inhibiting Crml results in increased inhibition of NF-kB and HIFl transcriptional activity (Muller 2009).
  • RXRa Retinoid X receptor a
  • RXRa Retinoid X receptor a
  • Lep B is able to prevent IL- ⁇ induced cytoplasmic increase in RXRa levels in human liver derived cells (Zimmerman 2006).
  • CRM1 Inhibition affects gene expression by inhibiting/activating a series of transcription factors like ICp27, E2F4, KLF5, YAP1, ZAP
  • Crml inhibition has potential therapeutic effects across many dermatologic syndromes including inflammatory dermatoses (atopy, allergic dermatitis, chemical dermatitis, psoriasis), sun-damage (Ultraviolet / UV damage), and infections.
  • CRMl inhibition best studied with LMB, showed minimal effects on normal keratinocytes, and exerted anti-inflammatory activity on keratinocytes subjected to UV, TNFa, or other inflammatory stimuli (Kobayashi & Shinkai 2005, Kannan & Jaiswal 2006).
  • NRF2 nuclear factor erythroid-related factor 2
  • LMB induces apoptosis in keratinocytes infected with oncogenic human papillomavirus (HPV) strains such as HPV16, but not in uninfected keratinocytes (Jolly et al, 2009).
  • HPV human papillomavirus
  • Crml also mediates the transport of key neuroprotectant proteins that may be useful in neurodegenerative diseases including Parkinson's Disease (PD), Alzheimer's Disease, and Amyotrophic Lateral Sclerosis. For example, (1) forcing nuclear retention of key neuroprotective regulators such as NRF2 (Wang 2009), FOXA2 (Kittappa et al, 2007), parking in neuronal cells and/or by (2) inhibiting NFKB transcriptional activity by

  • the HIV-1 Rev protein which traffics through nucleolus and shuttles between the nucleus and cytoplasm, facilitates export of unspliced and singly spliced HIV transcripts containing Rev Response Elements (RRE) RNA by the CRMl export pathway.
  • RRE Rev Response Elements
  • Inhibition of Rev-mediated RNA transport using CRMl inhibitors such as LepB or PKF050-638 can arrest the HIV-1 transcriptional process, inhibit the production of new HIV-1 virions, and thereby reduce HIV-1 levels (Pollard 1998, Daelemans 2002).
  • Dengue virus is the causative agent of the common arthropod-borne viral disease, dengue fever (DF), and its more severe and potentially deadly dengue hemorrhagic fever (DHF). DHF appears to be the result of an over exuberant inflammatory response to DENV.
  • NS5 is the largest and most conserved protein of DENV. CRMl regulates the transport of NS5 from the nucleus to the cytoplasm, where most of the NS5 functions are mediated.

  • CRMl inhibitors could therefore have beneficial effects on both the viral infectious process as well as on the process of neoplastic transformation due to these viruses.
  • CRMl controls the nuclear localization and therefore activity of multiple DNA metabolizing enzymes including histone deacetylases (HDAC), histone acetyltransferases (HAT), and histone methyltransferases (HMT). Suppression of cardiomyocyte hypertrophy with irreversible CRMl inhibitors has been demonstrated and is believed to be linked to nuclear retention (and activation) of HDAC 5, an enzyme known to suppress a hypertrophic genetic program (Monovich et al, 2009). Thus, CRMl inhibition may have beneficial effects in hypertrophic syndromes, including certain forms of congestive heart failure and hypertrophic cardiomyopathies.

  • Compounds and methods described herein may be used to treat or prevent a disease or disorder associated with angiogenesis.
  • Diseases associated with angiogenesis include cancer, cardiovascular disease and macular degeneration.
  • Angiogenesis is the physiological process involving the growth of new blood vessels from pre-existing vessels. Angiogenesis is a normal and vital process in growth and development, as well as in wound healing and in granulation tissue. However, it is also a fundamental step in the transition of tumors from a dormant state to a malignant one.
  • Angiogenesis may be a target for combating diseases characterized by either poor vascularisation or abnormal vasculature.
  • VEGF Vascular endothelial growth factor
  • Tumors induce blood vessel growth (angiogenesis) by secreting various growth factors ⁇ e.g., VEGF).
  • growth factors such as bFGF and VEGF can induce capillary growth into the tumor, which some researchers suspect supply required nutrients, allowing for tumor expansion.
  • Angiogenesis represents an excellent therapeutic target for the treatment of cardiovascular disease. It is a potent, physiological process that underlies the natural manner in which our bodies respond to a diminution of blood supply to vital organs, namely the production of new collateral vessels to overcome the ischemic insult.
  • VEGF vascular endothelial growth factor
  • VEGF causes increased permeability in blood vessels in addition to stimulating angiogenesis.
  • VEGF causes proliferation of capillaries into the retina. Since the increase in angiogenesis also causes edema, blood and other retinal fluids leak into the retina, causing loss of vision.
  • Anti-angiogenic therapy can include kinase inhibitors targeting vascular endothelial growth factor (VEGF) such as sunitinib, sorafenib, or monoclonal antibodies or receptor "decoys" to VEGF or VEGF receptor including bevacizumab or VEGF-Trap, or thalidomide or its analogs (lenalidomide, pomalidomide), or agents targeting non-VEGF angiogenic targets such as fibroblast growth factor (FGF), angiopoietins, or angiostatin or endo statin.
  • VEGF vascular endothelial growth factor
  • FGF fibroblast growth factor
  • angiopoietins angiostatin or endo statin.
  • Epigenetics is the study of heritable changes in phenotype or gene expression caused by mechanisms other than changes in the underlying DNA sequence.
  • epigenetic changes in eukaryotic biology is the process of cellular differentiation. During morphogenesis, stem cells become the various cell lines of the embryo which in turn become fully differentiated cells. In other words, a single fertilized egg cell changes into the many cell types including neurons, muscle cells, epithelium, blood vessels etc. as it continues to divide. It does so by activating some genes while inhibiting others.
  • Epigenetic changes are preserved when cells divide. Most epigenetic changes only occur within the course of one individual organism's lifetime, but, if a mutation in the DNA has been caused in sperm or egg cell that results in fertilization, then some epigenetic changes are inherited from one generation to the next. Specific epigenetic processes include paramutation, bookmarking, imprinting, gene silencing, X chromosome inactivation, position effect, reprograrnming, transvection, maternal effects, the progress of carcinogenesis, many effects of teratogens, regulation of histone modifications and heterochromatin, and technical limitations affecting parthenogenesis and cloning.
  • Exemplary diseases associated with epigenetics include ATR-syndrome, fragile X-syndrome, ICF syndrome, Angelman's syndrome, Prader-Wills syndrome, BWS, Rett syndrome, ot-thalassaemia, cancer, leukemia, Rubinstein-Taybi syndrome and Coffin-Lowry syndrome.
  • the first human disease to be linked to epigenetics was cancer.
  • DNA methylation occurs at CpG sites, and a majority of CpG cytosines are methylated in mammals.
  • CpG islands stretches of DNA near promoter regions that have higher concentrations of CpG sites (known as CpG islands) that are free of methylation in normal cells.
  • CpG islands become excessively methylated in cancer cells, thereby causing genes that should not be silenced to turn off.
  • This abnormality is the trademark epigenetic change that occurs in tumors and happens early in the development of cancer. Hypermethylation of CpG islands can cause tumors by shutting off tumor-suppressor genes. In fact, these types of changes may be more common in human cancer than DNA sequence mutations.
  • MGMT 06-methylguanine-DNA methyltransferase
  • CDKN2B MLH1 cyclin-dependent kinase inhibitor 2B
  • RASSF1A RASSF1A
  • hypermethylation of the promoter of MGMT causes the number of G-to-A mutations to increase.
  • Microsatellites are common in normal individuals, and they usually consist of repeats of the dinucleotide CA. Too much methylation of the promoter of the DNA repair gene MLH1 can make a micro satellite unstable and lengthen or shorten it. Microsatellite instability has been linked to many cancers, including colorectal, endometrial, ovarian, and gastric cancers.
  • Fragile X syndrome is the most frequently inherited mental disability, particularly in males. Both sexes can be affected by this condition, but because males only have one X chromosome, one fragile X will impact them more severely. Indeed, fragile X syndrome occurs in approximately 1 in 4,000 males and 1 in 8,000 females. People with this syndrome have severe intellectual disabilities, delayed verbal development, and "autistic-like" behavior.
  • Fragile X syndrome gets its name from the way the part of the X chromosome that contains the gene abnormality looks under a microscope; it usually appears as if it is hanging by a thread and easily breakable. The syndrome is caused by an abnormality in the FMR1 (fragile X mental retardation 1) gene. People who do not have fragile X syndrome have 6 to 50 repeats of the trinucleotide CGG in their FMR1 gene. However, individuals with over 200 repeats have a full mutation, and they usually show symptoms of the syndrome. Too many CGGs cause the CpG islands at the promoter region of the FMR1 gene to become
  • Fragile X syndrome is not the only disorder associated with mental retardation that involves epigenetic changes. Other such conditions include Rubenstein-Taybi, Coffin- Lowry, Prader-Willi, Angelman, Beckwith- Wiedemann, ATR-X, and Rett syndromes.
  • Epigenetic therapies include inhibitors of enzymes controlling epigenetic modifications, specifically DNA methyltransferases and histone deacetylases, which have shown promising anti-tumorigenic effects for some malignancies, as well as antisense oligonucleotides and siRNA.
  • a compound described herein is administered with an immunotherapy.
  • Cancer immunotherapy refers to a diverse set of therapeutic strategies designed to induce the patient's own immune system to fight the tumor.
  • Contemporary methods for generating an immune response against tumors include intravesicular BCG immunotherapy for superficial bladder cancer, prostate cancer vaccine Provenge, and use of interferons and other cytokines to induce an immune response in renal cell carcinoma and melanoma patients.
  • Allogeneic hematopoietic stem cell transplantation can be considered a form of immunotherapy, since the donor's immune cells will often attack the tumor in a graft-versus- tumor effect.

NUCLEAR TRANSPORT MODULATORS AND USES THEREOF

61/838,129, filed on June 21, 2013; U.S. Provisional Application No. 61/838,135, filed on June 21, 2013; U.S. Provisional Application No. 61/838,153, filed on June 21, 2013; and U.S. Provisional Application No. 61/842,475, filed on July 3, 2013. The entire teachings of these applications are incorporated herein by reference.
BACKGROUND OF THE INVENTION
[0002] Cells from most maj or human solid and hematologic malignancies exhibit abnormal cellular localization of a variety of oncogenic proteins, tumor suppressor proteins, and cell cycle regulators (Cronshaw et al, 2004, Falini et al 2006). For example, certain p53 mutations lead to localization in the cytoplasm rather than in the nucleus. This results in the loss of normal growth regulation, despite intact tumor suppressor function. In other tumors, wild-type p53 is sequestered in the cytoplasm or rapidly degraded, again leading to loss of its suppressor function. Restoration of appropriate nuclear localization of functional p53 protein can normalize some properties of neoplastic cells (Cai et al, 2008; Hoshino et al 2008; Lain et al 1999a; Lain et al 1999b; Smart et al 1999), can restore sensitivity of cancer cells to DNA damaging agents (Cai et al, 2008), and can lead to regression of established tumors (Sharpless & DePinho 2007, Xue et al, 2007). Similar data have been obtained for other tumor suppressor proteins such as forkhead (Turner and Sullivan 2008) and c-Abl (Vignari and Wang 2001). In addition, abnormal localization of several tumor suppressor and growth regulatory proteins may be involved in the pathogenesis of autoimmune diseases (Davis 2007, Nakahara 2009). CRM1 inhibition may provide particularly interesting utility in familial cancer syndromes (e.g., Li-Fraumeni Syndrome due to loss of one p53 allele, BRCA1 or 2 cancer syndromes), where specific tumor suppressor proteins (TSP) are deleted or dysfunctional and where increasing TSP levels by systemic (or local) administration of CRM1 inhibitors could help restore normal tumor suppressor function.
[0003] Specific proteins and RNAs are carried into and out of the nucleus by specialized transport molecules, which are classified as importins if they transport molecules into the nucleus, and exportins if they transport molecules out of the nucleus (Terry et al, 2007; Sorokin et al 2007). Proteins that are transported into or out of the nucleus contain nuclear import/localization (NLS) or export (NES) sequences that allow them to interact with the relevant transporters. Chromosomal Region Maintenance 1 (Crml), which is also called exportin-1 or Xpol , is a major exportin.
[0004] Overexpression of Crml has been reported in several tumors, including human ovarian cancer (Noske et al, 2008), cervical cancer (van der Watt et al, 2009), pancreatic cancer (Huang et al, 2009), hepatocellular carcinoma (Pascale et al, 2005) and osteosarcoma (Yao et al, 2009) and is independently correlated with poor clinical outcomes in these tumor types.
[0005] Inhibition of Crml blocks the exodus of tumor suppressor proteins and/or growth regulators such as p53, c-Abl, p21, p27, pRB, BRCA1 , IkB, ICp27, E2F4, KLF5, YAP1, ZAP, KLF5, HDAC4, FID AC 5 or forkhead proteins (e.g. FOX03a) from the nucleus that are associated with gene expression, cell proliferation, angiogenesis and epigenetics. Crml inhibitors have been shown to induce apoptosis in cancer cells even in the presence of activating oncogenic or growth stimulating signals, while sparing normal (untransformed) cells. Most studies of Crml inhibition have utilized the natural product Crml inhibitor Leptomycin B (LMB). LMB itself is highly toxic to neoplastic cells, but poorly tolerated with marked gastrointestinal toxicity in animals (Roberts et al, 1986) and humans (Newlands et al, 1996). Derivatization of LMB to improve drug-like properties leads to compounds that retain antitumor activity and are better tolerated in animal tumor models (Yang et al, 2007, Yang et al, 2008, Mutka et al, 2009). Therefore, nuclear export inhibitors could have beneficial effects in neoplastic and other proliferative disorders. To date, however, small- molecule, drug-like Crml inhibitors for use in vitro and in vivo are uncommon.
[0006] In addition to tumor suppressor proteins, Crml also exports several key proteins that are involved in many inflammatory processes. These include IkB, NF-kB, Cox-2, RXRa, Commdl, HIFl , HMGBl, FOXO, FOXP and others. The nuclear factor kappa B (NF-kB/rel) family of transcriptional activators, named for the discovery that it drives immunoglobulin kappa gene expression, regulate the mRNA expression of variety of genes involved in inflammation, proliferation, immunity and cell survival. Under basal conditions, a protein inhibitor of NF-kB, called IkB, binds to NF-kB in the nucleus and the complex IkB-NF-kB renders the NF-kB transcriptional function inactive. In response to inflammatory stimuli, IkB dissociates from the IkB-NF-kB complex, which releases NF-kB and unmasks its potent transcriptional activity. Many signals that activate NF-kB do so by targeting IkB for proteolysis (Phosphorylation of IkB renders it "marked" for ubiquitination and then proteolysis). The nuclear IkBa-NF-kB complex can be exported to the cytoplasm by Crml where it dissociates and NF-kB can be reactivated. Ubiquitinated IkB may also dissociate from the NF-kB complex, restoring NF-kB transcriptional activity. Inhibition of Crml induced export in human neutrophils and macrophage like cells (U937) by LMB not only results in accumulation of transcriptionally inactive, nuclear IkBa-NF-kB complex but also prevents the initial activation of NF-kB even upon cell stimulation (Ghosh 2008, Huang 2000). In a different study, treatment with LMB inhibited IL-Ιβ induced NF-kB DNA binding (the first step in NF-kB transcriptional activation), IL-8 expression and intercellular adhesion molecule expression in pulmonary microvascular endothelial cells (Walsh 2008). COMMDl is another nuclear inhibitor of both NF-kB and hypoxia- inducible factor 1 (HIFl) transcriptional activity. Blocking the nuclear export of COMMDl by inhibiting Crml results in increased inhibition of NF-kB and HIFl transcriptional activity (Muller 2009).
[0007] Crml also mediates Retinoid X receptor a (RXRa) transport. RXRa is highly expressed in the liver and plays a central role in regulating bile acid, cholesterol, fatty acid, steroid and xenobiotic metabolism and homeostasis. During liver inflammation, nuclear RXRa levels are significantly reduced, mainly due to inflammation-mediated nuclear export of RXRa by Crml. Lep B is able to prevent IL-Ιβ induced cytoplasmic increase in RXRa levels in human liver derived cells (Zimmerman 2006).
[0008] The role of Crml -mediated nuclear export in NF-kB, HIF- 1 and RXRa signalling suggests that blocking nuclear export can be potentially beneficial in many inflammatory processes across multiple tissues and organs including the vasculature (vasculitis, arteritis, polymyalgia rheumatic, atherosclerosis), dermatologic (see above), rheumatologic
(rheumatoid and related arthritis, psoriatic arthritis, spondyloarthropathies, crystal arthropathies, systemic lupus erythematosus, mixed connective tissue disease, myositis syndromes, dermatomyositis, inclusion body myositis, undifferentiated connective tissue disease, Sjogren's syndrome, scleroderma and overlap syndromes, etc.).
[0009] CRM1 Inhibition affects gene expression by inhibiting/activating a series of transcription factors like ICp27, E2F4, KLF5, YAP1, ZAP
[0010] Crml inhibition has potential therapeutic effects across many dermatologic syndromes including inflammatory dermatoses (atopy, allergic dermatitis, chemical dermatitis, psoriasis), sun-damage (Ultraviolet / UV damage), and infections. CRMl inhibition, best studied with LMB, showed minimal effects on normal keratinocytes, and exerted anti-inflammatory activity on keratinocytes subjected to UV, TNFa, or other inflammatory stimuli (Kobayashi & Shinkai 2005, Kannan & Jaiswal 2006). Crml inhibition also upregulates NRF2 (nuclear factor erythroid-related factor 2) activity, which protects keratinocytes (Schafer et al, 2010, Kannan & Jaiswal 2006) and other cell types (Wang et al, 2009) from oxidative damage. LMB induces apoptosis in keratinocytes infected with oncogenic human papillomavirus (HPV) strains such as HPV16, but not in uninfected keratinocytes (Jolly et al, 2009).
[0011] Crml also mediates the transport of key neuroprotectant proteins that may be useful in neurodegenerative diseases including Parkinson's Disease (PD), Alzheimer's Disease, and Amyotrophic Lateral Sclerosis. For example, (1) forcing nuclear retention of key neuroprotective regulators such as NRF2 (Wang 2009), FOXA2 (Kittappa et al, 2007), parking in neuronal cells and/or by (2) inhibiting NFKB transcriptional activity by
sequestering ΙκΒ to the nucleus in glial cells, Crml inhibition could slow or prevent neuronal cell death found in these disorders. There is also evidence linking abnormal glial cell proliferation to abnormalities in CRMl levels or CR1 function (Shen 2008).
[0012] Intact nuclear export, primarily mediated through CRMl, is also required for the intact maturation of many viruses. Viruses where nuclear export, and/or CRMl itself, has been implicated in their lifecycle include human immunodeficiency virus (HIV), adenovirus, simian retrovirus type 1, Borna disease virus, influenza (usual strains as well as H1N1 and avian H5N1 strains), hepatitis B (HBV) and C (HCV) viruses, human papillomavirus (HPV), respiratory syncytial virus (RSV), Dungee, Severe Acute Respiratory Syndrome coronavirus, yellow fever virus, West Nile Virus, herpes simplex virus (HSV), cytomegalovirus (CMV), and Merkel cell polyomavirus (MCV). (Bhuvanakantham 2010, Cohen 2010, Whittaker 1998). It is anticipated that additional viral infections reliant on intact nuclear export will be uncovered in the near future.
[0013] The HIV-1 Rev protein, which traffics through nucleolus and shuttles between the nucleus and cytoplasm, facilitates export of unspliced and singly spliced HIV transcripts containing Rev Response Elements (RRE) RNA by the CRMl export pathway. Inhibition of Rev-mediated RNA transport using CRMl inhibitors such as LepB or PKF050-638 can arrest the HIV-1 transcriptional process, inhibit the production of new HIV-1 virions, and thereby reduce HIV-1 levels (Pollard 1998, Daelemans 2002).
[0014] Dengue virus (DENV) is the causative agent of the common arthropod-borne viral disease, dengue fever (DF), and its more severe and potentially deadly dengue hemorrhagic fever (DHF). DHF appears to be the result of an over exuberant inflammatory response to DENV. NS5 is the largest and most conserved protein of DENV. CRMl regulates the transport of NS5 from the nucleus to the cytoplasm, where most of the NS5 functions are mediated. Inhibition of CRMl mediated export of NS5 results in altered kinetics of virus production and reduces induction of the inflammatory chemokine interleukin-8 (IL-8), presenting a new avenue for the treatment of diseases caused by DENV and other medically important flaviviruses including Hepatitis C virus (Rawlinson 2009).
[0015] Other virus-encoded RNA-binding proteins that use CRMl to exit the nucleus include the HSV type 1 tegument protein (VP 13/14, or hUL47), human CMV protein pp65, the SARS Coronavirus ORF 3b Protein, and the RSV matrix (M) protein (Williams 2008, Sanchez 2007, Freundt 2009, Ghildyal 2009).
[0016] Interestingly, many of these viruses are associated with specific types of human cancer including hepatocellular carcinoma (HCC) due to chronic HBV or HCV infection, cervical cancer due to HPV, and Merkel cell carcinoma associated with MCV. CRMl inhibitors could therefore have beneficial effects on both the viral infectious process as well as on the process of neoplastic transformation due to these viruses.
[0017] CRMl controls the nuclear localization and therefore activity of multiple DNA metabolizing enzymes including histone deacetylases (HDAC), histone acetyltransferases (HAT), and histone methyltransferases (HMT). Suppression of cardiomyocyte hypertrophy with irreversible CRMl inhibitors has been demonstrated and is believed to be linked to nuclear retention (and activation) of HDAC 5, an enzyme known to suppress a hypertrophic genetic program (Monovich et al, 2009). Thus, CRMl inhibition may have beneficial effects in hypertrophic syndromes, including certain forms of congestive heart failure and hypertrophic cardiomyopathies.
[0018] CRMl has also been linked to other disorders. Leber's disorder, a hereditary disorder characterized by degeneration of retinal ganglion cells and visual loss, is associated with inaction of the CRMl switch (Gupta N 2008). There is also evidence linking
neurodegenerative disorders to abnormalities in nuclear transport. [0019] In view of the above, the discovery of compounds that modulate nuclear transport is desirable.

, and mixtures thereof. Similarly, the following structural formula:
Figure imgf000048_0001
is meant to denote both and
Figure imgf000048_0002
, and mixtures thereof.
[00169] As used herein, "exocyclic double bond" refers to the carbon-carbon double bond in a compound of Structural Formula II and a compound of Structural Formula III indicated
with an arrow in the following structures:
Figure imgf000048_0003
respectively. In some embodiments described herein, the exocyclic double bond is in a cis configuration. In other embodiments, the exocyclic double bond is in a trans configuration.
[00170] The configuration of a carbon-carbon double bond, typically an exocyclic double bond in a compound of Structural Formula II or III, can be established by x-ray
crystallography. The application reflects whether a carbon-carbon double bond in a particular compound exists in a cis or trans configuration by indicating the configuration of the double bond in the chemical name associated with the compound.
[00171] As used herein, "cis" or "cis configuration" refers to a carbon-carbon double bond, typically an exocyclic double bond, that is predominantly cis. In some embodiments, greater than about 85% of compound molecules in a mixture of the compound have a carbon- carbon double bond (e.g. , an exocyclic double bond) that is cis. In some embodiments, greater than about 90%, greater than about 95%, greater than about 98%, greater than about 99%, greater than about 99.5% or greater than about 99.8% of compound molecules in a mixture of the compound have a carbon-carbon double bond (e.g. , an exocyclic double bond) that is cis.

[00173] Additionally, unless otherwise stated, structures depicted herein are also meant to include compounds that differ only in the presence of one or more isotopically enriched atoms. For example, compounds having the present structures including the replacement of hydrogen by deuterium or tritium, or the replacement of a carbon by a 13C- or 14C-enriched carbon are within the scope of this invention. Such compounds are useful, for example, as analytical tools, as probes in biological assays, or as therapeutic agents in accordance with the present invention.
[00174] The term "pharmaceutically acceptable salt" means either an acid addition salt or a basic addition salt which is compatible with the treatment of patients.
[00175] In some embodiments, exemplary inorganic acids which form suitable salts include, but are not limited thereto, hydrochloric, hydrobromic, sulfuric and phosphoric acid and acid metal salts such as sodium monohydrogen orthophosphate and potassium hydrogen sulfate. Illustrative organic acids which form suitable salts include the mono-, di- and tricarboxylic acids. Illustrative of such acids are, for example, acetic, trifluoro acetic acid (2,2,2-trifluoroacetic acid), glycolic, lactic, pyruvic, malonic, succinic, glutaric, fumaric, malic, tartaric, citric, ascorbic, maleic, hydroxymaleic, benzoic, hydroxybenzoic,
phenylacetic, cinnamic, salicylic, 2-phenoxybenzoic, p-toluenesulfonic acid and other sulfonic acids such as methanesulfonic acid and 2-hydroxyethanesulfonic acid. Either the mono- or di-acid salts can be formed, and such salts can exist in either a hydrated, solvated or substantially anhydrous form. In general, the acid addition salts of these compounds are more soluble in water and various hydrophilic organic solvents, and generally demonstrate higher melting points in comparison to their free base forms. Other non-pharmaceutically acceptable salts, e.g., oxalates may be used, for example, in the isolation of compounds described herein for laboratory use, or for subsequent conversion to a pharmaceutically acceptable acid addition salt.
[00176] A "pharmaceutically acceptable basic addition salt" is any non-toxic organic or inorganic base addition salt of the acid compounds described herein or any of its
intermediates. Illustrative inorganic bases which form suitable salts include, but are not limited thereto, lithium, sodium, potassium, calcium, magnesium or barium hydroxides. Illustrative organic bases which form suitable salts include aliphatic, alicyclic or aromatic organic amines such as methylamine, trimethyl amine and picoline or ammonia. The selection of the appropriate salt may be important so that an ester functionality, if any, elsewhere in the molecule is not hydrolyzed. The selection criteria for the appropriate salt will be known to one skilled in the art.
[00177] Acid addition salts of the compounds described herein are most suitably formed from pharmaceutically acceptable acids, and include, for example, those formed with inorganic acids, e.g., hydrochloric, sulphuric or phosphoric acids and organic acids, e.g., succinic, maleic, acetic, trifluoroacetic or fumaric acid. Other non-pharmaceutically acceptable salts, e.g., oxalates may be used for example in the isolation of compounds described herein for laboratory use, or for subsequent conversion to a pharmaceutically acceptable acid addition salt. Also included within the scope of the invention are base addition salts (such as sodium, potassium and ammonium salts), solvates and hydrates of compounds of the invention. The conversion of a given compound salt to a desired compound salt is achieved by applying standard techniques, well known to one skilled in the art.
[00178] The term "stereoisomers" is a general term for all isomers of the individual molecules that differ only in the orientation of their atoms in space. It includes mirror image isomers (enantiomers), geometric (cis/trans) isomers and isomers of compounds with more than one chiral centre that are not mirror images of one another (diastereomers).
[00179] The term "treat" or "treating" means to alleviate symptoms, eliminate the causation of the symptoms either on a temporary or permanent basis, or to prevent or slow the appearance of symptoms of the named disorder or condition. In the case of wound healing, a therapeutically effective amount is an amount that promotes healing of a wound.
[00180] As used herein, "promoting wound healing" means treating a subject with a wound and achieving healing, either partially or fully, of the wound. Promoting wound healing can mean, e.g., one or more of the following: promoting epidermal closure;
promoting migration of the dermis; promoting dermal closure in the dermis; reducing wound healing complications, e.g., hyperplasia of the epidermis and adhesions; reducing wound dehiscence; and promoting proper scab formation.
[00181] The term "therapeutically effective amount" means an amount of the compound which is effective in treating or lessening the severity of one or more symptoms of a disorder or condition.
[00182] The term "pharmaceutically acceptable carrier" means a non-toxic solvent, dispersant, excipient, adjuvant or other material which is mixed with the active ingredient in order to permit the formation of a pharmaceutical composition, i.e., a dosage form capable of being administered to a subject. One example of such a carrier is pharmaceutically acceptable oil typically used for parenteral administration. Pharmaceutically acceptable carriers are well known in the art.
[00183] When introducing elements disclosed herein, the articles "a", "an", "the", and "said" are intended to mean that there are one or more of the elements. The terms
"comprising", "having", "including" are intended to be open-ended and mean that there may be additional elements other than the listed elements.

Combination therapies
[00218] In some embodiments, a compound described herein is administered together with an additional "second" therapeutic agent or treatment. The choice of second therapeutic agent may be made from any agent that is typically used in a monotherapy to treat the indicated disease or condition. As used herein, the term "administered together" and related terms refers to the simultaneous or sequential administration of therapeutic agents in accordance with this invention. For example, a compound of the present invention may be administered with another therapeutic agent simultaneously or sequentially in separate unit dosage forms or together in a single unit dosage form. Accordingly, the present invention provides a single unit dosage form comprising a compound of the invention, an additional therapeutic agent, and a pharmaceutically acceptable carrier, adjuvant, or vehicle.
[00219] In one embodiment of the invention, where a second therapeutic agent is administered to a subject, the effective amount of the compound of this invention is less than its effective amount would be where the second therapeutic agent is not administered. In another embodiment, the effective amount of the second therapeutic agent is less than its effective amount would be where the compound of this invention is not administered. In this way, undesired side effects associated with high doses of either agent may be minimized. Other potential advantages (including without limitation improved dosing regimens and/or reduced drug cost) will be apparent to those of skill in the art. The additional agents may be administered separately, as part of a multiple dose regimen, from the compounds of this invention. Alternatively, those agents may be part of a single dosage form, mixed together with the compounds of this invention in a single composition.
Cancer Combination Therapies
[00220] In some embodiments, a compound described herein is administered together with an additional cancer treatment. Exemplary additional cancer treatments include, for example: chemotherapy, targeted therapies such as antibody therapies, kinase inhibitors, immunotherapy, and hormonal therapy, epigenetic therapy, proteosome inhibitors, and anti- angiogenic therapies. Examples of each of these treatments are provided below. As used herein, the term "combination," "combined," and related terms refer to the simultaneous or sequential administration of therapeutic agents in accordance with this invention. For example, a compound of the present invention can be administered with another therapeutic agent simultaneously or sequentially in separate unit dosage forms or together in a single unit dosage form. Accordingly, the present invention provides a single unit dosage form comprising a compound of the invention, an additional therapeutic agent, and a
pharmaceutically acceptable carrier, adjuvant, or vehicle.
[00221] The amount of both a compound of the invention and additional therapeutic agent (in those compositions which comprise an additional therapeutic agent as described above) that can be combined with the carrier materials to produce a single dosage form will vary depending upon the host treated and the particular mode of administration. Preferably, compositions of this invention should be formulated so that a dosage of between 0.01 - 100 mg/kg body weight/day of a compound of the invention can be administered.
Chemotherapy
[00222] In some embodiments, a compound described herein is administered with a chemotherapy. Chemotherapy is the treatment of cancer with drugs that can destroy cancer cells. "Chemotherapy" usually refers to cytotoxic drugs which affect rapidly dividing cells in general, in contrast with targeted therapy. Chemotherapy drugs interfere with cell division in various possible ways, e.g., with the duplication of DNA or the separation of newly formed chromosomes. Most forms of chemotherapy target all rapidly dividing cells and are not specific for cancer cells, although some degree of specificity may come from the inability of many cancer cells to repair DNA damage, while normal cells generally can.
[00223] Examples of chemotherapeutic agents used in cancer therapy include, for example, antimetabolites (e.g., folic acid, purine, and pyrimidine derivatives) and alkylating agents (e.g., nitrogen mustards, nitrosoureas, platinum, alkyl sulfonates, hydrazines, triazenes, aziridines, spindle poison, cytotoxic agents, topoisomerase inhibitors and others). Exemplary agents include Aclarubicin, Actinomycin, Alitretinoin, Altretamine, Aminopterin, Aminolevulinic acid, Amrubicin, Amsacrine, Anagrelide, Arsenic trioxide, Asparaginase, Atrasentan, Belotecan, Bexarotene, Bendamustin, Bleomycin, Bortezomib, Busulfan, Camptothecin, Capecitabine, Carboplatin, Carboquone, Carmofur, Carmustine, Celecoxib, Chlorambucil, Chlormethine, Cisplatin, Cladribine, Clofarabine, Crisantaspase, Cyclophosphamide, Cytarabine, Dacarbazine, Dactinomycin, Daunorubicin, Decitabine, Demecolcine, Docetaxel, Doxorubicin, Efaproxiral, Elesclomol, Elsamitrucin, Enocitabine, Epirubicin, Estramustine, Etoglucid, Etoposide, Floxuridine, Fludarabine, Fluorouracil (5FU), Fotemustine, Gemcitabine, Gliadel implants, Hydroxycarbamide, Hydroxyurea, Idarubicin, Ifosfamide, Irinotecan, Irofulven, Ixabepilone, Larotaxel, Leucovorin, Liposomal doxorubicin, Liposomal daunorubicin, Lonidamine, Lomustine, Lucanthone, Mannosulfan, Masoprocol, Melphalan, Mercaptopurine, Mesna, Methotrexate, Methyl aminolevulinate, Mitobronitol, Mitoguazone, Mitotane, Mitomycin, Mitoxantrone, Nedaplatin, Nimustine, Oblimersen, Omacetaxine, Ortataxel, Oxaliplatin, Paclitaxel, Pegaspargase, Pemetrexed, Pentostatin, Pirarubicin, Pixantrone, Plicamycin, Porfimer sodium, Prednimustine,

[00224] Because some drugs work better together than alone, two or more drugs are often given at the same time. Often, two or more chemotherapy agents are used as combination chemotherapy. In some embodiments, the chemotherapy agents (including combination chemotherapy) can be used in combination with a compound described herein.
Targeted therapy
[00225] Targeted therapy constitutes the use of agents specific for the deregulated proteins of cancer cells. Small molecule targeted therapy drugs are generally inhibitors of enzymatic domains on mutated, overexpressed, or otherwise critical proteins within the cancer cell. Prominent examples are the tyrosine kinase inhibitors such as Axitinib, Bosutinib, Cediranib, desatinib, erolotinib, imatinib, gefitinib, lapatinib, Lestaurtinib, Nilotinib, Semaxanib, Sorafenib, Sunitinib, and Vandetanib, and also cyclin-dependent kinase inhibitors such as Alvocidib and Seliciclib. Monoclonal antibody therapy is another strategy in which the therapeutic agent is an antibody which specifically binds to a protein on the surface of the cancer cells. Examples include the anti-HER2/neu antibody trastuzumab (Herceptin®) typically used in breast cancer, and the anti-CD20 antibody rituximab and Tositumomab typically used in a variety of B-cell malignancies. Other exemplary antibodies include Cetuximab, Panitumumab, Trastuzumab, Alemtuzumab, Bevacizumab, Edrecolomab, and Gemtuzumab. Exemplary fusion proteins include Aflibercept and Denileukin diftitox. In some embodiments, the targeted therapy can be used in combination with a compound described herein, e.g., Gleevec (Vignari and Wang 2001).
[00226] Targeted therapy can also involve small peptides as '¾oming devices" which can bind to cell surface receptors or affected extracellular matrix surrounding the tumor.
Radionuclides which are attached to these peptides (e.g., RGDs) eventually kill the cancer cell if the nuclide decays in the vicinity of the cell. An example of such therapy includes BEXXAR®.
Angiogenesis
[00227] Compounds and methods described herein may be used to treat or prevent a disease or disorder associated with angiogenesis. Diseases associated with angiogenesis include cancer, cardiovascular disease and macular degeneration.
[00228] Angiogenesis is the physiological process involving the growth of new blood vessels from pre-existing vessels. Angiogenesis is a normal and vital process in growth and development, as well as in wound healing and in granulation tissue. However, it is also a fundamental step in the transition of tumors from a dormant state to a malignant one.
Angiogenesis may be a target for combating diseases characterized by either poor vascularisation or abnormal vasculature.
[00229] Application of specific compounds that may inhibit or induce the creation of new blood vessels in the body may help combat such diseases. The presence of blood vessels where there should be none may affect the mechanical properties of a tissue, increasing the likelihood of failure. The absence of blood vessels in a repairing or otherwise metabolically active tissue may inhibit repair or other essential functions. Several diseases, such as ischemic chronic wounds, are the result of failure or insufficient blood vessel formation and may be treated by a local expansion of blood vessels, thus bringing new nutrients to the site, facilitating repair. Other diseases, such as age-related macular degeneration, may be created by a local expansion of blood vessels, interfering with normal physiological processes.
[00230] Vascular endothelial growth factor (VEGF) has been demonstrated to be a major contributor to angiogenesis, increasing the number of capillaries in a given network. Upregulation of VEGF is a major component of the physiological response to exercise and its role in angiogenesis is suspected to be a possible treatment in vascular injuries. In vitro studies clearly demonstrate that VEGF is a potent stimulator of angiogenesis because, in the presence of this growth factor, plated endothelial cells will proliferate and migrate, eventually forming tube structures resembling capillaries.
[00231] Tumors induce blood vessel growth (angiogenesis) by secreting various growth factors {e.g., VEGF). Growth factors such as bFGF and VEGF can induce capillary growth into the tumor, which some researchers suspect supply required nutrients, allowing for tumor expansion.
[00232] Angiogenesis represents an excellent therapeutic target for the treatment of cardiovascular disease. It is a potent, physiological process that underlies the natural manner in which our bodies respond to a diminution of blood supply to vital organs, namely the production of new collateral vessels to overcome the ischemic insult.
[00233] Overexpression of VEGF causes increased permeability in blood vessels in addition to stimulating angiogenesis. In wet macular degeneration, VEGF causes proliferation of capillaries into the retina. Since the increase in angiogenesis also causes edema, blood and other retinal fluids leak into the retina, causing loss of vision.
[00234] Anti-angiogenic therapy can include kinase inhibitors targeting vascular endothelial growth factor (VEGF) such as sunitinib, sorafenib, or monoclonal antibodies or receptor "decoys" to VEGF or VEGF receptor including bevacizumab or VEGF-Trap, or thalidomide or its analogs (lenalidomide, pomalidomide), or agents targeting non-VEGF angiogenic targets such as fibroblast growth factor (FGF), angiopoietins, or angiostatin or endo statin.
Epigenetics
[00235] Compounds and methods described herein may be used to treat or prevent a disease or disorder associated with epigenetics. Epigenetics is the study of heritable changes in phenotype or gene expression caused by mechanisms other than changes in the underlying DNA sequence. One example of epigenetic changes in eukaryotic biology is the process of cellular differentiation. During morphogenesis, stem cells become the various cell lines of the embryo which in turn become fully differentiated cells. In other words, a single fertilized egg cell changes into the many cell types including neurons, muscle cells, epithelium, blood vessels etc. as it continues to divide. It does so by activating some genes while inhibiting others.
[00236] Epigenetic changes are preserved when cells divide. Most epigenetic changes only occur within the course of one individual organism's lifetime, but, if a mutation in the DNA has been caused in sperm or egg cell that results in fertilization, then some epigenetic changes are inherited from one generation to the next. Specific epigenetic processes include paramutation, bookmarking, imprinting, gene silencing, X chromosome inactivation, position effect, reprograrnming, transvection, maternal effects, the progress of carcinogenesis, many effects of teratogens, regulation of histone modifications and heterochromatin, and technical limitations affecting parthenogenesis and cloning.
[00237] Exemplary diseases associated with epigenetics include ATR-syndrome, fragile X-syndrome, ICF syndrome, Angelman's syndrome, Prader-Wills syndrome, BWS, Rett syndrome, ot-thalassaemia, cancer, leukemia, Rubinstein-Taybi syndrome and Coffin-Lowry syndrome.
[00238] The first human disease to be linked to epigenetics was cancer. Researchers found that diseased tissue from patients with colorectal cancer had less DNA methylation than normal tissue from the same patients. Because methylated genes are typically turned off, loss of DNA methylation can cause abnormally high gene activation by altering the arrangement of chromatin. On the other hand, too much methylation can undo the work of protective tumor suppressor genes.
[00239] DNA methylation occurs at CpG sites, and a majority of CpG cytosines are methylated in mammals. However, there are stretches of DNA near promoter regions that have higher concentrations of CpG sites (known as CpG islands) that are free of methylation in normal cells. These CpG islands become excessively methylated in cancer cells, thereby causing genes that should not be silenced to turn off. This abnormality is the trademark epigenetic change that occurs in tumors and happens early in the development of cancer. Hypermethylation of CpG islands can cause tumors by shutting off tumor-suppressor genes. In fact, these types of changes may be more common in human cancer than DNA sequence mutations.
[00240] Furthermore, although epigenetic changes do not alter the sequence of DNA, they can cause mutations. About half of the genes that cause familial or inherited forms of cancer are turned off by methylation. Most of these genes normally suppress tumor formation and help repair DNA, including 06-methylguanine-DNA methyltransferase (MGMT), MLH1 cyclin-dependent kinase inhibitor 2B (CDKN2B), and RASSF1A. For example,
hypermethylation of the promoter of MGMT causes the number of G-to-A mutations to increase.
[00241] Hypermethylation can also lead to instability of micro satellites, which are repeated sequences of DNA. Microsatellites are common in normal individuals, and they usually consist of repeats of the dinucleotide CA. Too much methylation of the promoter of the DNA repair gene MLH1 can make a micro satellite unstable and lengthen or shorten it. Microsatellite instability has been linked to many cancers, including colorectal, endometrial, ovarian, and gastric cancers.
[00242] Fragile X syndrome is the most frequently inherited mental disability, particularly in males. Both sexes can be affected by this condition, but because males only have one X chromosome, one fragile X will impact them more severely. Indeed, fragile X syndrome occurs in approximately 1 in 4,000 males and 1 in 8,000 females. People with this syndrome have severe intellectual disabilities, delayed verbal development, and "autistic-like" behavior.
[00243] Fragile X syndrome gets its name from the way the part of the X chromosome that contains the gene abnormality looks under a microscope; it usually appears as if it is hanging by a thread and easily breakable. The syndrome is caused by an abnormality in the FMR1 (fragile X mental retardation 1) gene. People who do not have fragile X syndrome have 6 to 50 repeats of the trinucleotide CGG in their FMR1 gene. However, individuals with over 200 repeats have a full mutation, and they usually show symptoms of the syndrome. Too many CGGs cause the CpG islands at the promoter region of the FMR1 gene to become
methylated; normally, they are not. This methylation turns the gene off, stopping the FMR1 gene from producing an important protein called fragile X mental retardation protein. Loss of this specific protein causes fragile X syndrome. Although a lot of attention has been given to the CGG expansion mutation as the cause of fragile X, the epigenetic change associated with FMR1 methylation is the real syndrome culprit.
[00244] Fragile X syndrome is not the only disorder associated with mental retardation that involves epigenetic changes. Other such conditions include Rubenstein-Taybi, Coffin- Lowry, Prader-Willi, Angelman, Beckwith- Wiedemann, ATR-X, and Rett syndromes.
[00245] Epigenetic therapies include inhibitors of enzymes controlling epigenetic modifications, specifically DNA methyltransferases and histone deacetylases, which have shown promising anti-tumorigenic effects for some malignancies, as well as antisense oligonucleotides and siRNA.
Immunotherapy
[00246] In some embodiments, a compound described herein is administered with an immunotherapy. Cancer immunotherapy refers to a diverse set of therapeutic strategies designed to induce the patient's own immune system to fight the tumor. Contemporary methods for generating an immune response against tumors include intravesicular BCG immunotherapy for superficial bladder cancer, prostate cancer vaccine Provenge, and use of interferons and other cytokines to induce an immune response in renal cell carcinoma and melanoma patients.
[00247] Allogeneic hematopoietic stem cell transplantation can be considered a form of immunotherapy, since the donor's immune cells will often attack the tumor in a graft-versus- tumor effect. In some embodiments, the immunotherapy agents can be used in combination with a compound described herein.
Hormonal therapy
[00248] In some embodiments, a compound described herein is administered with a hormonal therapy. The growth of some cancers can be inhibited by providing or blocking certain hormones. Common examples of hormone- sensitive tumors include certain types of breast and prostate cancers, as well as certain types of leukemia which respond to certain retinoids/retinoic acids. Removing or blocking estrogen or testosterone is often an important additional treatment. In certain cancers, administration of hormone agonists, such as progestogens may be therapeutically beneficial. In some embodiments, the hormonal therapy agents can be used in combination with a compound described herein.
[00249] Hormonal therapy agents include the administration of hormone agonists or hormone antagonists and include retinoids/retinoic acid, compounds that inhibit estrogen or testosterone, as well as administration of progestogens.

In another embodiment, the other therapeutic agent is a PDE4 inhibitor (e.g., roflumilast or rolipram). In another embodiment, the other therapeutic agent is an antihistamine (e.g. , cyclizine, hydroxyzine, promethazine or diphenhydramine). In another embodiment, the other therapeutic agent is an anti-malarial (e.g., artemisinin, artemether, artsunate, chloroquine phosphate, mefloquine hydrochloride, doxycycline hyclate, proguanil hydrochloride, atovaquone or halofantrine). In one embodiment, the other compound is drotrecogin alfa.

Neurodegenerative disease
[00266] Neurodegeneration is the umbrella term for the progressive loss of structure or function of neurons, including death of neurons. Many neurodegenerative diseases including Parkinson's, Alzheimer's, and Huntington's occur as a result of neurodegenerative processes. As research progresses, many similarities appear which relate these diseases to one another on a sub-cellular level. Discovering these similarities offers hope for therapeutic advances that could ameliorate many diseases simultaneously. There are many parallels between different neurodegenerative disorders including atypical protein assemblies as well as induced cell death.
[00267] Alzheimer's disease is characterized by loss of neurons and synapses in the cerebral cortex and certain subcortical regions. This loss results in gross atrophy of the affected regions, including degeneration in the temporal lobe and parietal lobe, and parts of the frontal cortex and cingulate gyrus.
[00268] Huntington's disease causes astrogliosis and loss of medium spiny neurons. Areas of the brain are affected according to their structure and the types of neurons they contain, reducing in size as they cumulatively lose cells. The areas affected are mainly in the striatum, but also the frontal and temporal cortices. The striatum's subthalamic nuclei send control signals to the globus pallidus, which initiates and modulates motion. The weaker signals from subthalamic nuclei thus cause reduced initiation and modulation of movement, resulting in the characteristic movements of the disorder. Exemplary treatments for Huntington's disease include tetrabenazine, neuroleptics, benzodiazepines, amantadine, remacemide, valproic acid, selective serotonin reuptake inhibitors (SSRIs), mirtazapine and antipsychotics.
[00269] The mechanism by which the brain cells in Parkinson's are lost may consist of an abnormal accumulation of the protein alpha-synuclein bound to ubiquitin in the damaged cells. The alpha-synuclein-ubiquitin complex cannot be directed to the proteosome. This protein accumulation forms proteinaceous cytoplasmic inclusions called Lewy bodies. The latest research on pathogenesis of disease has shown that the death of dopaminergic neurons by alpha-synuclein is due to a defect in the machinery that transports proteins between two major cellular organelles— the endoplasmic reticulum (ER) and the Golgi apparatus. Certain proteins like Rabl may reverse this defect caused by alpha-synuclein in animal models. Exemplary Parkinson's disease therapies include levodopa, dopamine agonists such as include bromocriptine, pergolide, pramipexole, ropinirole, piribedil, cabergoline,
apomorphine and lisuride, dopa decarboxylate inhibitors, MAO-B inhibitors such as selegilene and rasagilene, anticholinergics and amantadine,
[00270] Amyotrophic lateral sclerosis (ALS/Lou Gehrig's Disease) is a disease in which motor neurons are selectively targeted for degeneration. Exemplary ALS therapies include riluzole, baclofen, diazepam, trihexyphenidyl and amitriptyline.
[00271] Other exemplary neurodegenerative therapeutics include antisense
oligonucleotides and stem cells.
Wound Healing
[00272] Wounds are a type of condition characterized by cell or tissue damage. Wound healing is a dynamic pathway that optimally leads to restoration of tissue integrity and function. The wound healing process consists of three overlapping phases. The first phase is an inflammatory phase, which is characterized by homeostasis, platelet aggregation and degranulation. Platelets as the first response, release multiple growth factors to recruit immune cells, epithelial cells, and endothelial cells. The inflammatory phase typically occurs over days 0-5. The second stage of wound healing is the proliferative phase during which macrophages and granulocytes invade the wound. Infiltrating fibroblasts begin to produce collagen. The principle characteristics of this phase are epithelialization, angiogenesis, granulation tissue formation and collagen production. The proliferative phase typically occurs over days 3-14. The third phase is the remodeling phase where matrix formation occurs. The fibroblasts, epithelial cells, and endothelial cells continue to produce collagen and collagenase as well as matrix metalloproteases (MMPs) for remodeling. Collagen crosslinking takes place and the wound undergoes contraction. The remodeling phase typically occurs from day 7 to one year.
[00273] Compounds and compositions described herein can be used for promoting wound healing (e.g. , promoting or accelerating wound closure and/or wound healing, mitigating scar fibrosis of the tissue of and/or around the wound, inhibiting apoptosis of cells surrounding or proximate to the wound). Thus, in certain embodiments, the present invention provides a method for promoting wound healing in a subject, comprising administering to the subject a therapeutically effective amount of a compound (e.g., a CRM1 inhibitor), or
pharmaceutically acceptable salt or composition thereof. The method need not achieve complete healing or closure of the wound; it is sufficient for the method to promote any degree of wound closure. In this respect, the method can be employed alone or as an adjunct to other methods for healing wounded tissue.
[00274] The compounds and compositions described herein can be used to treat wounds during the inflammatory (or early) phase, during the proliferative (or middle) wound healing phase, and/or during the remodeling (or late) wound healing phase.
[00275] In some embodiments, the subject in need of wound healing is a human or an animal, for example, a dog, a cat, a horse, a pig, or a rodent, such as a mouse.
[00276] In some embodiments, the compounds and compositions described herein useful for wound healing are administered topically, for example, proximate to the wound site, or systemically.
[00277] More specifically, a therapeutically effective amount of a compound or composition described herein can be administered (optionally in combination with other agents) to the wound site by coating the wound or applying a bandage, packing material, stitches, etc., that are coated or treated with the compound or composition described herein. As such, the compounds and compositions described herein can be formulated for topical administration to treat surface wounds. Topical formulations include those for delivery via the mouth (buccal) and to the skin such that a layer of skin (i. e., the epidermis, dermis, and/or subcutaneous layer) is contacted with the compound or composition described herein. Topical delivery systems may be used to administer topical formulations of the compounds and compositions described herein.
[00278] Alternatively, the compounds and compositions described herein can be administered at or near the wound site by, for example, injection of a solution, injection of an extended release formulation, or introduction of a biodegradable implant comprising the compound or composition described herein.
[00279] The compounds and compositions described herein can be used to treat acute wounds or chronic wounds. A chronic wound results when the normal reparative process is interrupted. Chronic wounds can develop from acute injuries as a result of unrecognized persistent infections or inadequate primary treatment. In most cases however, chronic lesions are the end stage of progressive tissue breakdown owing to venous, arterial, or metabolic vascular disease, pressure sores, radiation damage, or tumors.
[00280] In chronic wounds, healing does not occur for a variety of reasons, including improper circulation in diabetic ulcers, significant necrosis, such as in burns, and infections. In these chronic wounds, viability or the recovery phase is often the rate-limiting step. The cells are no longer viable and, thus, initial recovery phase is prolonged by unfavorable wound bed environment.
[00281] Chronic wounds include, but are not limited to the following: chronic ischemic skin lesions; scleroderma ulcers; arterial ulcers; diabetic foot ulcers; pressure ulcers; venous ulcers; non-healing lower extremity wounds; ulcers due to inflammatory conditions; and/or long-standing wounds. Other examples of chronic wounds include chronic ulcers, diabetic wounds, wounds caused by diabetic neuropathy, venous insufficiencies, and arterial insufficiencies, and pressure wounds and cold and warm burns. Yet other examples of chronic wounds include chronic ulcers, diabetic wounds, wounds caused by diabetic neuropathy, venous insufficiencies, arterial insufficiencies, and pressure wounds.
[00282] Acute wounds include, but are not limited to, post-surgical wounds, lacerations, hemorrhoids and fissures.
[00283] In a particular embodiment, the compounds and compositions described herein can be used for diabetic wound healing or accelerating healing of leg and foot ulcers secondary to diabetes or ischemia in a subject.
[00284] In one embodiment, the wound is a surface wound. In another embodiment, the wound is a surgical wound (e.g., abdominal or gastrointestinal surgical wound). In a further embodiment, the wound is a burn. In yet another embodiment, the wound is the result of radiation exposure.
[00285] The compounds and compositions described herein can also be used for diabetic wound healing, gastrointestinal wound healing, or healing of an adhesion due, for example, to an operation.
[00286] The compounds and compositions described herein can also be used to heal wounds that are secondary to another disease. For example, in inflammatory skin diseases, such as psoriasis and dermatitis, there are numerous incidents of skin lesions that are secondary to the disease, and are caused by deep cracking of the skin, or scratching of the skin. The compounds and compositions described herein can be used to heal wounds that are secondary to these diseases, for example, inflammatory skin diseases, such as psoriasis and dermatitis.
[00287] In a further embodiment, the wound is an internal wound. In a specific aspect, the internal wound is a chronic wound. In another specific aspect, the wound is a vascular wound. In yet another specific aspect, the internal wound is an ulcer. Examples of internal wounds include, but are not limited to, fistulas and internal wounds associated with cosmetic surgery, internal indications, Crohn's disease, ulcerative colitis, internal surgical sutures and skeletal fixation. Other examples of internal wounds include, but are not limited to, fistulas and internal wounds associated with cosmetic surgery, internal indications, internal surgical sutures and skeletal fixation.
[00288] Examples of wounds include, but are not limited to, abrasions, avulsions, blowing wounds (i.e., open pneumothorax), burn wounds, contusions, gunshot wounds, incised wounds, open wounds, penetrating wounds, perforating wounds, puncture wounds, seton wounds, stab wounds, surgical wounds, subcutaneous wounds, diabetic lesions, or tangential wounds. Additional examples of wounds that can be treated by the compounds and compositions described herein include acute conditions or wounds, such as thermal burns, chemical burns, radiation burns, burns caused by excess exposure to ultraviolet radiation {e.g., sunburn); damage to bodily tissues, such as the perineum as a result of labor and childbirth; injuries sustained during medical procedures, such as episiotomies; trauma- induced injuries including cuts, incisions, excoriations; injuries sustained from accidents; post-surgical injuries, as well as chronic conditions, such as pressure sores, bedsores, conditions related to diabetes and poor circulation, and all types of acne. In addition, the wound can include dermatitis, such as impetigo, intertrigo, folliculitis and eczema, wounds following dental surgery; periodontal disease; wounds following trauma; and tumor- associated wounds. Yet other examples of wounds include animal bites, arterial disease, insect stings and bites, bone infections, compromised skin/muscle grafts, gangrene, skin tears or lacerations, skin aging, surgical incisions, including slow or non-healing surgical wounds, intracerebral hemorrhage, aneurysm, dermal asthenia, and post-operation infections.
[00289] In preferred embodiments, the wound is selected from the group consisting of a burn wound, an incised wound, an open wound, a surgical or post surgical wound, a diabetic lesion, a thermal burn, a chemical burn, a radiation burn, a pressure sore, a bedsore, and a condition related to diabetes or poor circulation. In more preferred embodiments, the wound is selected from the group consisting of an incised wound, an open wound, a surgical or post surgical wound, a diabetic lesion, a pressure sore, a bedsore, and a condition or wound related to diabetes or poor circulation.
[00290] In some embodiments, the wound is selected from the group consisting of a non- radiation burn wound, an incised wound, an open wound, a surgical or post surgical wound, a diabetic lesion, a thermal burn, a chemical burn, a pressure sore, a bedsore, and a condition related to diabetes or poor circulation. In some embodiments, the wound is selected from the group consisting of an incised wound, an open wound, a surgical or post surgical wound, a diabetic lesion, a pressure sore, a bedsore, and a condition related to diabetes or poor circulation.
[00291] The present disclosure also relates to methods and compositions of reducing scar formation during wound healing in a subject. The compounds and compositions described herein can be administered directly to the wound or to cells proximate the wound at an amount effective to reduce scar formation in and/or around the wound. Thus, in some embodiments, a method of reducing scar formation during wound healing in a subject is provided, the method comprising administering to the subject a therapeutically effective amount of a compound described herein (e.g., a CRM1 inhibitor), or a pharmaceutically acceptable salt thereof.
[00292] The wound can include any injury to any portion of the body of a subject.
According to embodiments, methods are provided to ameliorate, reduce, or decrease the formation of scars in a subject that has suffered a burn injury. According to preferred embodiments, methods are provided to treat, reduce the occurrence of, or reduce the probability of developing hypertrophic scars in a subject that has suffered an acute or chronic wound or injury.
Other disorders
[00293] Compounds and compositions described herein may also be used to treat disorders of abnormal tissue growth and fibrosis including dilative cardiomyopathy, hypertrophic cardiomyopathy, restrictive cardiomyopathy, pulmonary fibrosis, hepatic fibrosis, glomerulonephritis, and other renal disorders.
Combination Radiation Therapy
[00294] Compounds and compositions described herein are useful as radiosensitizers. Therefore, compounds and compositions described herein can be administered in
combination with radiation therapy. Radiation therapy is the medical use of high-energy radiation (e.g. , x-rays, gamma rays, charged particles) to shrink tumors and kill malignant cells, and is generally used as part of cancer treatment. Radiation therapy kills malignant cells by damaging their DNA.
[00295] Radiation therapy can be delivered to a patient in several ways. For example, radiation can be delivered from an external source, such as a machine outside the patient's body, as in external beam radiation therapy. External beam radiation therapy for the treatment of cancer uses a radiation source that is external to the patient, typically either a radioisotope, such as 60Co, 137Cs, or a high energy x-ray source, such as a linear accelerator. The external source produces a collimated beam directed into the patient to the tumor site. External-source radiation therapy avoids some of the problems of internal- source radiation therapy, but it undesirably and necessarily irradiates a significant volume of non-tumorous or healthy tissue in the path of the radiation beam along with the tumorous tissue.
[00296] The adverse effect of irradiating of healthy tissue can be reduced, while maintaining a given dose of radiation in the tumorous tissue, by projecting the external radiation beam into the patient at a variety of "gantry" angles with the beams converging on the tumor site. The particular volume elements of healthy tissue, along the path of the radiation beam, change, reducing the total dose to each such element of healthy tissue during the entire treatment.
[00297] The irradiation of healthy tissue also can be reduced by tightly collimating the radiation beam to the general cross section of the tumor taken perpendicular to the axis of the radiation beam. Numerous systems exist for producing such a circumferential collimation, some of which use multiple sliding shutters which, piecewise, can generate a radio-opaque mask of arbitrary outline.
[00298] For administration of external beam radiation, the amount can be at least about 1 Gray (Gy) fractions at least once every other day to a treatment volume. In a particular embodiment, the radiation is administered in at least about 2 Gray (Gy) fractions at least once per day to a treatment volume. In another particular embodiment, the radiation is
administered in at least about 2 Gray (Gy) fractions at least once per day to a treatment volume for five consecutive days per week. In another particular embodiment, radiation is administered in 10 Gy fractions every other day, three times per week to a treatment volume. In another particular embodiment, a total of at least about 20 Gy is administered to a patient in need thereof. In another particular embodiment, at least about 30 Gy is administered to a patient in need thereof. In another particular embodiment, at least about 40 Gy is
administered to a patient in need thereof.
[00299] Typically, the patient receives external beam therapy four or five times a week. An entire course of treatment usually lasts from one to seven weeks depending on the type of cancer and the goal of treatment. For example, a patient can receive a dose of 2 Gy/day over 30 days.
[00300] Internal radiation therapy is localized radiation therapy, meaning the radiation source is placed at the site of the tumor or affected area. Internal radiation therapy can be delivered by placing a radiation source inside or next to the area requiring treatment. Internal radiation therapy is also called brachytherapy. Brachytherapy includes intercavitary treatment and interstitial treatment. In intracavitary treatment, containers that hold radioactive sources are put in or near the tumor. The sources are put into the body cavities. In interstitial treatment, the radioactive sources alone are put into the tumor. These radioactive sources can stay in the patient permanently. Typically, the radioactive sources are removed from the patient after several days. The radioactive sources are in containers.
[00301] There are a number of methods for administration of a radiopharmaceutical agent. For example, the radiopharmaceutical agent can be administered by targeted delivery or by systemic delivery of targeted radioactive conjugates, such as a radiolabeled antibody, a radiolabeled peptide and a liposome delivery system. In one particular embodiment of targeted delivery, the radiolabeled pharmaceutical agent can be a radiolabeled antibody. See, for example, Ballangrud A. M., et al. Cancer Res., 2001 ; 61 :2008-2014 and Goldenber, D.M. J Nucl. Med. , 2002; 43(5):693-713, the contents of which are incorporated by reference herein.
[00302] In another particular embodiment of targeted delivery, the radiopharmaceutical agent can be administered in the form of liposome delivery systems, such as small unilamellar vesicles, large unilamellar vesicles and multilamellar vesicles. Liposomes can be formed from a variety of phospholipids, such as cholesterol, stearylamine or
phosphatidylcholines. See, for example, Emfietzoglou D, Kostarelos , Sgouros G. An analytical dosimetry study for the use of radionuclide-liposome conjugates in internal radiotherapy. J Nucl Med 2001; 42:499-504, the contents of which are incorporated by reference herein.
[00303] In yet another particular embodiment of targeted delivery, the radiolabeled pharmaceutical agent can be a radiolabeled peptide. See, for example, Weiner RE, Thakur ML. Radiolabeled peptides in the diagnosis and therapy of oncological diseases. Appl Radiat Isot 2002 Nov;57(5):749-63, the contents of which are incorporated by reference herein.
[00304] In addition to targeted delivery, bracytherapy can be used to deliver the radiopharmaceutical agent to the target site. Brachytherapy is a technique that puts the radiation sources as close as possible to the tumor site. Often the source is inserted directly into the tumor. The radioactive sources can be in the form of wires, seeds or rods. Generally, cesium, iridium or iodine are used.
[00305] Systemic radiation therapy is another type of radiation therapy and involves the use of radioactive substances in the blood. Systemic radiation therapy is a form of targeted therapy. In systemic radiation therapy, a patient typically ingests or receives an injection of a radioactive substance, such as radioactive iodine or a radioactive substance bound to a monoclonal antibody.
[00306] A "radiopharmaceutical agent," as defined herein, refers to a pharmaceutical agent which contains at least one radiation- emitting radioisotope. Radiopharmaceutical agents are routinely used in nuclear medicine for the diagnosis and/or therapy of various diseases. The radiolabeled pharmaceutical agent, for example, a radiolabeled antibody, contains a radioisotope (RI) which serves as the radiation source. As contemplated herein, the term "radioisotope" includes metallic and non-metallic radioisotopes. The radioisotope is chosen based on the medical application of the radiolabeled pharmaceutical agents. When the radioisotope is a metallic radioisotope, a chelator is typically employed to bind the metallic radioisotope to the rest of the molecule. When the radioisotope is a non-metallic radioisotope, the non-metallic radioisotope is typically linked directly, or via a linker, to the rest of the molecule.

[00308] As used herein, a "non-metallic radioisotope" is any suitable nonmetallic radioisotope (non-metallic radioisotope) useful in a therapeutic or diagnostic procedure in vivo or in vitro. Suitable non-metallic radioisotopes include, but are not limited to: Iodine- 131, Iodine-125, Iodine-123, Phosphorus-32, Astatine-211, Fluorine-18, Carbon-11, Oxygen- 15, Bromine-76, and Nitrogen-13.
[00309] Identifying the most appropriate isotope for radiotherapy requires weighing a variety of factors. These include tumor uptake and retention, blood clearance, rate of radiation delivery, half-life and specific activity of the radioisotope, and the feasibility of large-scale production of the radioisotope in an economical fashion. The key point for a therapeutic radiopharmaceutical is to deliver the requisite amount of radiation dose to the tumor cells and to achieve a cytotoxic or tumoricidal effect while not causing unmanageable side-effects.
[00310] It is preferred that the physical half-life of the therapeutic radioisotope be similar to the biological half-life of the radiopharmaceutical at the tumor site. For example, if the half-life of the radioisotope is too short, much of the decay will have occurred before the radiopharmaceutical has reached maximum target/background ratio. On the other hand, too long a half-life could cause unnecessary radiation dose to normal tissues. Ideally, the radioisotope should have a long enough half-life to attain a minimum dose rate and to irradiate all the cells during the most radiation sensitive phases of the cell cycle. In addition, the half-life of a radioisotope has to be long enough to allow adequate time for
manufacturing, release, and transportation.
[00311] Other practical considerations in selecting a radioisotope for a given application in tumor therapy are availability and quality. The purity has to be sufficient and reproducible, as trace amounts of impurities can affect the radiolabeling and radiochemical purity of the radiopharmaceutical.
[00312] The target receptor sites in tumors are typically limited in number. As such, it is preferred that the radioisotope have high specific activity. The specific activity depends primarily on the production method. Trace metal contaminants must be minimized as they often compete with the radioisotope for the chelator and their metal complexes compete for receptor binding with the radiolabeled chelated agent.
[00313] The type of radiation that is suitable for use in the methods of the present invention can vary. For example, radiation can be electromagnetic or particulate in nature. Electromagnetic radiation useful in the practice of this invention includes, but is not limited to, x-rays and gamma rays. Particulate radiation useful in the practice of this invention includes, but is not limited to, electron beams (beta particles), protons beams, neutron beams, alpha particles, and negative pi mesons. The radiation can be delivered using conventional radiological treatment apparatus and methods, and by intraoperative and stereotactic methods. Additional discussion regarding radiation treatments suitable for use in the practice of this invention can be found throughout Steven A. Leibel et al., Textbook of Radiation Oncology (1998) (publ. W. B. Saunders Company), and particularly in Chapters 13 and 14. Radiation can also be delivered by other methods such as targeted delivery, for example by radioactive "seeds," or by systemic delivery of targeted radioactive conjugates. J. Padawer et ah, Combined Treatment with Radioestradiol lucanthone in Mouse C3HBA Mammary
Adenocarcinoma and with Estradiol lucanthone in an Estrogen Bioassay, Int. J. Radiat.
Oncol. Biol. Phys. 7:347-357 (1981). Other radiation delivery methods can be used in the practice of this invention.
[00314] For tumor therapy, both a and β-particle emitters have been investigated. Alpha particles are particularly good cytotoxic agents because they dissipate a large amount of energy within one or two cell diameters. The β -particle emitters have relatively long penetration range (2-12 mm in the tissue) depending on the energy level. The long-range penetration is particularly important for solid tumors that have heterogeneous blood flow and/or receptor expression. The β-particle emitters yield a more homogeneous dose distribution even when they are heterogeneously distributed within the target tissue.
[00315] In a particular embodiment, therapeutically effective amounts of the compounds and compositions described herein are administered in combination with a therapeutically effective amount of radiation therapy to treat cancer {e.g., lung cancer, such as non-small cell lung cancer). The amount of radiation necessary can be determined by one of skill in the art based on known doses for a particular type of cancer. See, for example, Cancer Medicine 5th ed., Edited by R.C. Bast et al, July 2000, BC Decker.

[00317] Throughout the following description of such processes it is to be understood that, where appropriate, suitable protecting groups will be added to, and subsequently removed from, the various reactants and intermediates in a manner that will be readily understood by one skilled in the art of organic synthesis. Conventional procedures for using such protecting groups as well as examples of suitable protecting groups are described, for example, in "Protective Groups in Organic Synthesis", T.W. Green, P.G.M. Wuts, Wiley-Interscience, New York, (1999). It is also to be understood that a transformation of a group or substituent into another group or substituent by chemical manipulation can be conducted on any intermediate or final product on the synthetic path toward the final product, in which the possible type of transformation is limited only by inherent incompatibility of other functionalities carried by the molecule at that stage to the conditions or reagents employed in the transformation. Such inherent incompatibilities, and ways to circumvent them by carrying out appropriate transformations and synthetic steps in a suitable order, will be readily understood to the one skilled in the art of organic synthesis. Examples of
transformations are given below, and it is to be understood that the described transformations are not limited only to the generic groups or substituents for which the transformations are exemplified. References and descriptions on other suitable transformations are given in "Comprehensive Organic Transformations - A Guide to Functional Group Preparations" R. C. Larock, VHC Publishers, Inc. (1989). References and descriptions of other suitable reactions are described in textbooks of organic chemistry, for example, "Advanced Organic Chemistry", March, 4th ed. McGraw Hill (1992) or, "Organic Synthesis", Smith, McGraw Hill, (1994). Techniques for purification of intermediates and final products include for example, straight and reversed phase chromatography on column or rotating plate, recrystallization, distillation and liquid-liquid or solid-liquid extraction, which will be readily understood by the one skilled in the art. The definitions of substituents and groups are as in formula I except where defined differently. The term "room temperature" and "ambient temperature" shall mean, unless otherwise specified, a temperature between 16 and 25 °C. The term "reflux" shall mean, unless otherwise stated, in reference to an employed solvent a temperature at or above the boiling point of named solvent.

Example 4. Assays. Certain compounds of the invention were tested in various assays. MTT Cell Proliferation Assay
[00372] The MTT cell proliferation assay was used to study the cytotoxic properties of the compounds. The assay was performed according to the method described by Roche
Molecular Biochemicals, with minor modifications. The assay is based on the cleavage of the tetrazolium salt, MTT, in the presence of an electron-coupling reagent. The water-insoluble formazan salt produced must be solubilized in an additional step. Cells grown in a 96-well tissue culture plate were incubated with the MTT solution for approximately 4 hours. After this incubation period, a water-insoluble formazan dye formed. After solubilization, the formazan dye was quantitated using a scanning multi-well spectrophotometer (ELISA reader). The absorbance revealed directly correlates to the cell number. The cells were seeded at 5,000-10,000 cells in each well of 96-well plate in 100 \iL of fresh culture medium and were allowed to attach overnight. The stock solutions of the compounds were diluted in 100xL cell culture medium to obtain eight concentrations of each test compound, ranging from 1 nM to 30 μΜ. After incubation for approximately 64-72 hours, 20 xL of CellTiter 96 Aqueous One Solution Reagent (Promega, G358B) was added to each well and the plate was returned to the incubator (37 °C; 5% C02) until an absolute OD of 1.5 was reached for the control cells. All optical densities were measured at 490 run using a Vmax Kinetic Microplate Reader (Molecular Devices). In most cases, the assay was performed in duplicate and the results were presented as a mean percent inhibition to the negative control±SE. The following formula was used to calculate the percent of inhibition: Inhibition (%) = (1- (ODo/OD)) X 100. [00373] The compounds were tested against Zl 38, MMl S and 3T3 cells. The Zl 38 cell line is a mature B-cell acute lymphoblastic leukemia cell line derived from a patient with chronic lumphocytic leukemia. The MMl S cell line was established from the peripheral blood of a human multiple myeloma patient. 3T3 cells are standard fibroblast cells; they were originally isolated from Swiss mouse embryo tissue.
[00374] The results of the MTT assay are reported in Tables 1 , 2 and 3.
