Epothilone D (KOS-862 or BMS-241027) is an intermediary obtained in the synthesis of members of the epothilone family and is a small-molecule microtubule stabilizer. It was investigated in Phase II trials in colorectal, metastatic breast and non-small-cell lung cancers. However, development was discontinued in 2007 in favor of a second-generation analog with a better safety profile. This drug also was studied for the treatment of Alzheimer's disease. The study ended in October 2013, and evaluation of epothilone D for Alzheimer's disease was subsequently discontinued. The mechanism by which epothilones induce microtubule polymerization appears to be similar to that of paclitaxel, in that epothilones compete with paclitaxel for binding to microtubules and suppress microtubule dynamics in a manner similar to that of paclitaxel.

Class (Stereo):
CHEMICAL (EPIMERIC)

Berefrine (also known as phenylephrine oxazolidine), a prodrug of phenylephrine, is a mydriatic agent. Berefrine was developed for improving ocular absorption and reducing systemic side effects.
m-Chlorophenylpiperazine (meta-chlorophenylpiperazine or mCPP) is a psychoactive substance, which is illegal in many countries but can be found on the black market. It induces endocrine, neurological and psychiatric effects. mCPP is a partial agonist at the 5-HT2C receptor but antagonized the 5-HT2B and 5-HT3 receptors. mCPP is also an active metabolite of the drug trazodone, which is used as an effective antidepressant drug with a broad therapeutic spectrum, including anxiolytic efficacy. It is known, that mCPP induces migraine attacks and that the decrease of food intake induced by the mCPP depends on its ability to act as a serotonin agonist is a brain.
Metoprine is a diaminopyrimidine folate antagonist with potential antineoplastic activity. Metoprine inhibits dihydrofolate reductase, resulting in decreased cellular folate metabolism and cell growth. Metoprine shows potent in vitro antitumor activity against several experimental tumors including methotrexate-resistant tumors. Metoprine inhibits the enzyme dihydrofolate reductase, much less effectively than methotrexate but it also inhibits histamine-N-methyltransferase, resulting in decreased histamine catabolism. S phase cells are most sensitive, whilst cells in G2 and M are least sensitive to the lethal effects of Metoprine, and a prolonged exposure to a high Metoprine concentration produces maximum cytotoxic effects. After oral administration, Metoprine has a widespread distribution and concentration in all tissues examined with the highest tissue/plasma ratios found in brain, lung, pancreas, and skin. Phase I and early Phase II clinical trials in various centers have shown activity in hypernephroma, epidermoid carcinoma arising in bronchus or head and neck, central nervous system leukemia, malignant melanoma, and mycosis fungicides. Metoprine had been in some phase II clinical trials but further studies were discontinued due to CNS and hematological toxicity.

Class (Stereo):
CHEMICAL (ACHIRAL)

Thyromedan is a thyroalkanoic acid derivative with hypocholesterolemic activity. In clinical trials, Thyromedan in daily doses of 8 to 32 mg caused a decrease in serum cholesterol levels. The serum total triglycerides and the α- and β-lipoprotein partition of cholesterol and triglycerides were unaffected.

Cadazolid is a new antibiotic in development for the treatment of Clostridium difficile-associated diarrhea. Cadazolid is active against all (including linezolid- and moxifloxacin-resistant) Clostridium difficile strains. In phase I and II clinical trials, cadazolid was shown to be safe, well tolerated, and efficacious positioning itself as a potential future viable therapeutic option for CDI. Using a series of macromolecular labeling, in vitro transcription/translation, and topoisomerase studies, it was determined that protein synthesis inhibition via the oxazolidinone moiety is the primary mechanism of action of cadazolid. Cadazolid is in phase III clinical trials by Actelion Pharmaceuticals for the treatment of Clostridium difficile infection. The US FDA has designated cadazolid as both a Qualified Infectious Disease Product (QIDP) and a Fast Track development program for this indication.

INN:halofenate

Class (Stereo):
CHEMICAL (RACEMIC)

Halofenate (MK-185) was invented as a hypolipidemic and hypouricemic agent. It was shown that halofenate lower serum triglycerides and uric acid in patients with a variety of hyperlipidemias. Treatment of dyslipidemic type 2 diabetic patients also showed triglyceride lowering and, surprisingly, significant reductions in plasma glucose and insulin. Halofenate is a selective PPAR-γ modulator (SPPARγM). SPPARγMs are believed to bind in distinct manners to the ligand-binding pocket of PPAR-γ, leading to altered receptor conformational stability and resulting in distinct patterns of gene expression. Thus, was suggested that halofenate hold promising therapeutic potential in the treatment of type 2 diabetes, without the side effects. However, information about the current use of this compound is not available.

CHEMICAL (ACHIRAL)

Chloracyzine is phenothiazine derivative with vasodilatory activity. Chloracyzine produced a decrease in myocardial oxygen consumption accompanied by a reduction in coronary blood flow preceded by transient coronary dilatation. Chloracyzine produced an insignificant increase in arterial pressure; heart rate increased slightly in the open-chest experiments but not in the isolated heart. It is suggested that reduced oxygen uptake after chloracyzine is realized through improved efficiency in the use of oxygen.
