       [0001]    The present application claims priority to U.S. Provisional Application No. 62/042,990, filed Aug. 28, 2014, entitled, “3,5, N-Trihydroxy-Alkanamide or 3,5,N-Trihydroxy-6-Alkanamide Derivative Alone or in a Combination with Chemotherapeutic Agent for Treating Cancer,” the entire contents of which is incorporated herein for all purposes by this reference. 
     
    
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
       [0002]    The invention relates to a combination which comprises: (a) a 3,5,N-trihydroxy-alkanamide, 3,5,N-trihydroxy-6-alkenamide or a derivative thereof; and (b) one or more chemotherapeutic agents, for simultaneous, concurrent, separate or sequential use, especially for use in the treatment of cancers and cancer metastases. The invention also relates to a kit comprising such a combination and to a method of treating cancers and cancer metastases. The present invention further also relates to a commercial package or product comprising such a combination. 
       2. Description of Related Art 
       [0003]    Colorectal cancer (CRC) is an important cancer with rising annual incidence worldwide, leading to significant morbidity and mortality. Most newly diagnosed CRC patients have localized diseases, for whom surgical resection with or without adjuvant chemotherapy provides chance of cure (1, 2). Despite aggressive treatment, a substantial proportion of patients suffer from metastatic CRC which includes metastatic diseases at diagnosis and metastatic recurrence. Metastatic CRC is a systemic disease essentially unresectable and remains incurable. Although new chemotherapeutic and molecular targeted agents in the past two decades prolong the survival from 12 to 24 months (3), the development of new drugs is crucial to further prolong the survival of metastatic CRC. 
         [0004]    Statins reduce serum cholesterol levels by competitively inhibiting 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase (HMGR), which is the rate-limiting enzyme in mevalonate and cholesterol biosynthesis. They are widely utilized to treat hypercholesterolemia and contribute to the decreased incidence of cardiovascular and cerebrovascular disorders (4). Statins have also shown promise related to cancer prevention in observational and preclinical studies and in certain aspects of randomized controlled studies (5). 
         [0005]    We first demonstrated that statins with a carboxylic acid-containing long chain abrogate histone deacetylase (HDAC) activity to induce p21 expression through promoter histone-H3 acetylation and exert anti-proliferation and anti-tumor effect (6). Accordingly, statins can suppress tumor formation through inhibition of both HMGR and HDAC activities. Overexpression of HDACs inactivating tumor suppressor genes has been reported in cancer cells, supporting that HDACs are attractive drug discovery targets (7). 
         [0006]    To further improve statins&#39; HDAC inhibition, a drug potently inhibiting both HMGR and HDACs was sought. We designed and synthesized a series of 3,5,N-trihydroxy-alkanamide, 3,5,N-trihydroxy-6-alkenamide and their derivatives, that directly inhibited HMGR and class I and II HDACs, which suppressed cell viability in a variety of cancer cells but not normal cells (8). More specifically, PCT Patent Application No. W02014015235 reports 3,5,N-trihydroxy-alkanamide, 3,5,N-trihydroxy-6-alkenamide and their derivatives with HMGR and HDAC inhibitory activities.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0027]    The following specific examples are used to exemplify the present invention. A person of ordinary skills in the art can conceive the other advantages of the present invention, based on the disclosure of the specification of the present invention. The present invention can also be implemented or applied as described in different specific examples. It is possible to modify and or alter the examples for carrying out this invention without contravening its spirit and scope, for different aspects and applications. 
         [0028]    It is further noted that, as used in this specification, the singular forms “a,” “an,” and “the” include plural referents unless expressly and unequivocally limited to one referent. The term “or” is used interchangeably with the term “and/or” unless the context clearly indicates otherwise. 
         [0029]    The term “cancer” used herein refers to any of many diseases characterized by the presence of cancerous tissue in a subject. As used herein, “cancerous tissue” refers to a tissue that comprises malignant neoplastic cells, exhibits an abnormal growth of cells and/or hyperproliferative cells. Cancerous tissue can be a primary malignant tumor, arising from a tissue or organ of origin, or it can be a metastatic malignant tumor, growing in a body tissue which was not the source of the original tumor. 
         [0030]    The term “metastasis” refers to the spread of cancer cells from its original site to another part of the body. The formation of metastasis is a very complex process and normally involves detachment of cancer cells from a primary tumor, entering the body circulation and settling down to grow within normal tissues elsewhere in the body. When tumor cells metastasize, the new tumor is called a secondary or metastatic tumor, and its cells normally resemble those in the original tumor. 
         [0031]    The term “chemotherapeutic agent” used herein refers to an agent that reduces, prevents, mitigates, limits, and/or delays the growth of metastases or neoplasms, or kills neoplastic cells directly by necrosis or apoptosis of neoplasms or any other mechanism, or that can be otherwise used, in a pharmaceutically-effective amount, to reduce, prevent, mitigate, limit, and/or delay the growth of metastases or neoplasms in a subject with neoplastic disease. Chemotherapeutic agents include, for example, alkylating agents, such as cyclophosphamide, ifosfamide, cisplatin, carboplatin, oxaliplatin and temozolomide; topoisomerase inhibitors, such as amonafide, amrubicin, amsacrine, campathecin, doxorubicin, epirubicin, etoposide, exatecan and irinotecan; antimetabolite agents, such as 5-fluorouracil, leucovorin, cladribine, capecitabine, mercaptopurine, pemetrexed, methotrexate, gemcitabine, hydroxyurea and cytarabine; and anti-mitotic agents, such aspaclitaxel, docetaxel, vinblastine, vincristine and vinorelbine. 
         [0032]    The term “cancer therapy” used herein refers to any method(s), composition(s), and/or agent(s) that can be used in the treatment of a cancer or one or more symptoms thereof. Cancer therapies include, for example, chemotherapy, radiation therapy, and targeted therapy. As used herein, “targeted therapy” refers to a means which acts directly against abnormal proteins in cancer cells. The targeted therapy may comprise, for example, administering a therapeutic agent such as bevacizumab, trastuzumab and cetuximab to a subject. 
         [0033]    Many examples have been used to illustrate the present invention. The examples below should not be taken as a limit to the scope of the invention. 
       EXAMPLES 
     Example 1 
     Animal Model of AOM/DSS-Induced CRC 
       [0034]    AOM in conjunction with the additional DSS inflammatory stimulus results in tumor development that is restricted to the colon in mice (11, 12). This model is widely utilized to recapitulate human colorectal cancer because it results in inflammation and ulceration of the entire colon, similar to what is observed in patients (12). CRC was induced in male C57BL/6 mice via the intraperitoneal injection of AOM (12.5 mg/kg) while the mice were maintained with a regular diet and drinking water for 7 days and then subjecting to 3 cycles of DSS treatment, with each cycle consisting of the administration of 3.5% DSS for 5 days followed by a 14-day recovery period with regular water ( FIG. 1A ). After 8 weeks, JMF3086 (25 mg/kg, 5 days/week) was orally administered to mice, oxaliplatin (5 mg/kg, once a week) was intraperitoneally administered to mice, and JMF3086 (25 mg/kg, 5 days/week) and oxaliplatin (5 mg/kg, once a week), irinotecan or 5-fluorouracil (5-FU) were administered to mice for additional two weeks. JMF3086 or oxaliplatin alone modestly reduced the number of tumors and sizes ( FIG. 1B ). However, combined treatment of JMF3086 and oxaliplatin significantly reduced CRC tumor growth ( FIG. 1B ). These results indicated that combined treatment enhanced the therapeutic effect of oxaliplatin on AOM/DSS-induced CRC. 
       Example 2 
     Animal Model for Experimental Colorectal Cancer Metastasis to the Liver and the Lung 
       [0035]    Seven-week-old female NOD/SCID mice were obtained from the National Laboratory Animal Center. The mice were anesthetized by continuous flow of 2-3% isoflurane. To generate liver metastases derived from human colorectal cancer cells in mouse models, HT29-Luciferase expressing cells (1×10 6 ) were suspended in 100 μl PBS and injected into the spleen of mice. After one-week recovery, the mice were randomized into vehicle and treatment group. Mice were oral administration of JMF3086 (5 days/week), intraperitoneally administered oxaliplatin, irinotecan or 5-FU (once a week) or a combination of oxaliplatin and JM3086, irinotecan and JM3086 or 5-FU and JM3086 for additional two weeks. Mice were then given endotoxon-free luciferse substrate and photographed by IVIS imaging system (Xenogen) once a week. Tumors in spleen and liver were collected and weighed after sacrificed. 
         [0036]    Metastasis is a major cause of death for CRC, and most CRC patients develop lung or liver metastasis (9, 10).To evaluate the anti-metastatic activity of JMF3086 and oxaliplatin or irinotecan combined treatment, HT29-Luciferase expressing cells were injected into the spleen of NOD/SCID mice and photographed by IVIS imaging system ( FIG. 2A ). A significant amount of tumor cells growing in the spleen and liver after one week injection was observed, and JMF3086 or oxaliplatin or irinotecan alone modestly inhibited the liver metastasis ( FIGS. 2B and 2C ). However, combined treatment of JMF3086 and oxaliplatin or irinotecan significantly reduced CRC metastasis to liver ( FIGS. 2B and 2C ). 
         [0037]    Besides, to examine the anti-metastatic activity of JMF3086, colorectal cancer cells (HCT116) were intravenously injected into nude mice via the tail vein ( FIG. 2D ). JMF3086 (100 mg/kg) reduced lung tumor nodules by macroscopic observation ( FIG. 2E ), indicating its inhibition on lung metastasis. 
         [0038]    Angiogenesis is an essential step of tumor growth and metastasis (13). To determining the effect of JMF3086 on angiogenesis, HCT116 cells treated with 30 μM JMF3086 for 20 hours were exposed to hypoxia for 4 hours, then conditional medium was collected and subcutaneous matrigel plug assay was conducted by injecting of 75 μl conditional medium mixed with 425 μl matrigel and 50 U heparin/ml into nude mice (5 mice/group). Mice were sacrificed and dissected after 14 days. Matrigel plug retrieved from mice were photographed. Quantification of neovessel formation in matrigel plugs were estimated using Drabkin reagent kit 525. 
         [0039]    Conditioned medium from HCT116 cell sunder hypoxia induced angiogenesis by matrigel plug assay in mice, and this effect was inhibited by JMF3086 ( FIG. 2F ), indicating that JMF3086 had anti-angiogenesis effect. 
       Example 3 
     Development of Orthotopic Lung Cancer Models 
       [0040]    In this Example, we use A549 cells [non-small cell lung cancer cell line with KRAS mutations (EGFR wild-type)] to establish the orthotopic lung cancer models. Seven-week-old male NOD/SCID mice were anesthetized by continuous flow of 2-3% isoflurane. A549-Luc cells (2×10 6 ) suspended in 40 μl of PBS were injected percutaneously into the right lung of the mice using 500 μl Gas-Tight syringes with 27G top winged infusion set. These mice were then given endotoxon-free luciferse substrate and photographed using IVIS-200 imaging system once a week. When lung tumor nodules were detected, the mice were oral administration of JMF3086 (5 days/week), intraperitoneally administered cisplatin (once a week) or a combination of JM3086 and cisplatin for additional two weeks ( FIG. 3A ). A significant amount of tumor cells growing in the lung after one week injection was observed, and JMF3086 or cisplatin alone ineffectively inhibited the lung cancer development ( FIG. 3B ). However, combined treatment of JMF3086 and cisplatin significantly reduced the tumor cells growth in the lung ( FIG. 3B ). 
       Example 4 
     Cell Proliferation Assay 
       [0041]    Human ovarian cancer cells (Hela) and breast cancer cells (MD-MBA-231, MCF7) were seeded at 3000 cells/well in 96-well plates and maintained for 14-16 hours, then treated with JMF3086 or gemcitabine or both. After 72 hours, cells were washed with PBS then added medium containing MTT reagent (Sigma) at a final concentration of 0.5 mg/ml for 4 hours. Then, the medium was replaced with 200 μl of DMSO for 30 minutes, and using an ELISA reader (570 nm) to get the absorbance density values. The 50% of inhibition concentration (IC 50 ) of death cells was calculated. 
       Example 5 
     Effect of 3,5,N-trihydroxy-alkanamide Derivatives on Cell Viability 
       [0042]    Effect of three 3,5,N-trihydroxy-alkanamide derivatives, JMF3086, (3R,5R)-7-{(1S,2S,6R,8S,8aR)-hexahydro-2,6-dimethyl-8-[2-dimethylbutyryloxy]naphthalenyl}-3,5-dihydroxy-N-hydroxyheptanamide (also referred to as JMF3171), and (3R,5R)-7-{[2-(4-fluoro-phenyl)-5isopropyl-3-phenyl-4-phenylcarbamoylpyrrol-1-yl]-3,5-dihydroxy-N-hydroxyheptanamide (also referred to as JMF3173) and the corresponding statins on the cell viability of various human cancer cell lines was determined by cell proliferation assay as described in Example 4. Specifically, cancer cells were treated with various concentrations of test compounds for 72 hours, and cell viability was measured by MTT assay. The half maximal inhibitory concentration (IC 50 ) values for individual cell line were calculated. 
         [0043]    As shown in  FIG. 4 , the three 3,5,N-trihydroxy-alkanamide derivatives, JMF3086, JMF3171, and JMF3173, were cytotoxic in CRC and various cancer cell lines. 
       Example 6 
     Chromatin Immunoprecipitation (ChIP) and ChIP-on-Chip Assays 
       [0044]    Colorectal cancer cells (HCT116) were treated with 30 μM JMF3086 for 24 hours, ChIP assays using control Rabbit IgG (sc-2027; Santa Cruz) or anti-H3K27-ac antibody (#4353; Cell Signaling) were performed as previously described (14). 
         [0045]    ChIP-on-chip assays were performed in the Microarray and Gene Expression Analysis Core Facility of the National Yang-Ming University VGH Genome Research Center in Taiwan using the SurePrint G3 Human Promoter 1×1M Kit (Agilent Technologies) after DNA was further purified through phenol/chloroform/isoamyl alcohol extraction and ethanol precipitation. Genes with two-fold down-regulation or up-regulation of H3K27-Ac in log-ratio after JMF 3086 treatment were regarded as significance. 
         [0046]    CHIP-on-chip analysis revealed that the binding of H3K27-acetylation to more than 10,000 genes has been altered by JMF3086. Those with two-fold down-regulation or up-regulation in log-ratio were selected and analyzed by Gene Ontology (GO) which categorized them into different biological functions, and the most significant ones were apoptosis and inflammation. Ingenuity Pathways Analysis (IPA) analysis predicted their regulation by NR3C1 and NF-κB, respectively ( FIGS. 5A and 5B ). JMF3086 inhibited the binding of H3K27-Ac to the gene promoters of inflammation and proliferation, stemness of cancer, and anti-apoptosis as well as reduced their mRNA expression. On the other hand, JM3086 increased the binding of H3K27-Ac to the gene promoters of tumor suppressors and also increased their mRNA expression ( FIG. 5C ). 
         [0047]    To further investigate these differential effects of JMF3086, the bindings of acetyl-H3K27, CBP, HDAC1 and HDAC3 to promoter were examined by quantitative ChIP (qChIP) assays. JMF3086 reduced the bindings of acetyl-H3K27 and CBP to the promoters of TNF-α, CD166, COX-2, BCL2, CXCL1, CXCL2, EpCAM, CD44, Cyclin D1 and MCL1, but increased those of HDAC1 and HDAC3 to the promoters ( FIG. 5D ). In contrast, JMF3086 increased the bindings of acetyl-H3K27 and CBP to the promoters of TIMP3, BMP2 and p53 but decreased those of HDAC1 and HDAC3 to their promoters ( FIG. 5D ). 
         [0048]    While some of the embodiments of the present invention have been described in detail in the above, it is, however, possible for those of ordinary skill in the art to make various modifications and changes to the particular embodiments shown without substantially departing from the teaching and advantages of the present invention. Such modifications and changes are encompassed in the spirit and scope of the present invention as set forth in the appended claim.
