Entinostat (MS-275) is an orally active, highly selective, small-molecule histone deacetylase inhibitor (HDACi) derived from benzamide. Entinostat preferentially inhibited HDAC1 versus HDAC3 and had no inhibitory activity toward HDAC8. The time to maximum plasma concentration (tmax) of entinostat ranged from 0.5 to 60h (median of 2h). Elimination of the drug was bi-exponential, with a terminal half-life of 30-80h. Entinostat is a well-tolerated that demonstrates promising therapeutic potential in both solid and hematologic malignancies. Its efficacy does not appear directly dose-related, and as such, more relevant biomarkers are needed to adequately assess its activity.

5-Fluoro-2-deoxycytidine is a fluorinated pyrimidine analog antimetabolite with potential antineoplastic activity. As a prodrug, 5-fluoro-2-deoxycytidine is converted by intracellular deaminases to the cytotoxic agent 5-fluorouracil (5-FU). 5-FU is subsequently metabolized to active metabolites including 5-fluoro-2-deoxyuridine monophosphate (FdUMP) and 5-fluorouridine triphosphate (FUTP). FdUMP binds to and inhibits thymidylate synthase, thereby reducing the production of thymidine monophosphate, which leads to depletion of thymidine triphosphate and the inhibition of DNA synthesis and cell division. FUTP competes with uridine triphosphate (UTP) for incorporation into the RNA strand, which results in the inhibition of RNA and protein synthesis and cell proliferation. 5-Fluoro-2-deoxycytidine undergoing trials to test its effectiveness in treating cancer that has not responded to standard therapies.

Axitirome (also known as CGS 26214), a thyroid hormone receptor β selective agonist and an LDL receptor function stimulant, has a cholesterol-lowering activity. This drug was in phase I clinical trials for the treatment of hyperlipidemia, but studies were discontinued because of the unexpected side effects.

Triapine (3-aminopyridine-2-carboxaldehyde thiosemcirbazone, (3-AP; NTO-1151; OCX-0191) is a novel small molecule ribonucleotide reductase inhibitor that acts on the M2 (R2) subunit. Ribonucleotide reductase is an enzyme involved in the de novo synthesis of deoxyribonucleotides, which are critical for DNA replication and DNA repair. Triapine has been used in trials phase II studying the treatment of Lung Cancer, Kidney Cancer, Prostate Cancer Pancreatic Cancer, among others. Recently was published the article describing, that the triple combination triapine-cisplatin-paclitaxel was safe and provided a rational basis for a follow-up phase II trial to evaluate the efficacy and progression-free survival in women with metastatic or recurrent uterine cervix cancer.

CHEMICAL (ACHIRAL)

Morpheridine is a pethidine analog with strong analgesic activity. Morpheridine does not cause convulsions, although it produces the standard opioid side effects such as sedation and respiratory depression. Morpheridine is not currently used in medicine and is a Schedule I drug which is controlled under United Nations drug conventions.

Dolastatin 10 is an unusual peptide of marine origin which binds to tubulin, inhibits microtubule assembly, resulting in the formation of tubulin aggregates and inhibition of mitosis. Dolastatin 10 has been used in trials phase II studying the treatment of Sarcoma, Leukemia, Lymphoma, Liver Cancer, among others. In case of hormone-refractory prostate cancer, it lacks significant clinical activity as a single agent and also dolastatin-10 is inactive against hepatobiliary and pancreatic carcinomas.

Daporinad is an inhibitor of nicotinamide phosphoribosyltransferase (NMPRTase), an enzyme that participates in the biosynthesis of nicotinamide adenine dinucleotide (NAD+) from niacinamide (vitamin B3). Inhibition of NMPRTase may deplete energy reserves in metabolically active tumor cells and induce tumor cell apoptosis. In addition, this agent may inhibit tumor cell production of vascular endothelial growth factor (VEGF), resulting in the inhibition of tumor angiogenesis. Daporinad was investigated as a treatment of B-cell chronic lymphocytic leukemia, melanoma, and cutaneous T-cell lymphoma. Clinical trials have shown that drug has low efficacy when used alone.
MKC-1 is an orally available cell cycle inhibitor with downstream targets that include tubulin and the importin-β family. MKC-1 has shown broad antitumor activity in preclinical models. MKC-1 and its metabolites inhibit tubulin polymerization, blocking the formation of the mitotic spindle, which may result in cell cycle arrest at the G2/M phase and apoptosis. In addition, this agent has been shown to inhibit the activities of the oncogenic kinase Akt, the mTOR pathway, and importin-beta, a protein essential to the transport of other proteins from the cytosol into the nucleus. MKC-1 had been in phase II clinical trials for the treatment of ovarian cancer, endometrial cancer, pancreatic cancer and breast cancer. This compound was originally discovered by Roche, then licensed to EntreMed (now CASI Pharmaceuticals) the exclusive worldwide rights to develop and commercialize. However, no recent development has been reported.
