Volixibat (SHP626; formerly LUM002) is a potent inhibitor of the apical sodium-dependent bile acid transporter (ASBT) that was developed for the treatment of nonalcoholic steatohepatitis. Volixibat participated in phase II clinical trial to investigate its safety, effectiveness in adults with nonalcoholic steatohepatitis. However, this study was discontinued, without any further explanation for the possible causes. In addition, volixibat was studied in a clinical trial in healthy adults and in patients with type 2 diabetes mellitus, where was shown that the drug was generally well tolerated.

LAROMUSTINE is a sulfonylhydrazine alkylating agent. It is metabolized to yield a chloroethylating compound (VNP-4090-CE) and a carbamoylating compound (methyl isocyanate). The former is primarily responsible for the antineoplastic effect of LAROMUSTINE. It alkylates the O6 position of guanine, resulting in DNA crosslinking, strand breaks, chromosomal aberrations, and disruption of DNA synthesis. The carbamoylating species contribute to antitumor activity by inhibiting O6-alkylguanine transferase, an enzyme involved with DNA repair. It was studied in the treatment of several types of cancer, however, its development was discontinued.

Ionomycin is an ionophore produced by the bacterium Streptomyces conglobatus. The molecules act as a motile Ca2+ carrier and enhances Ca2+ influx by direct stimulation of store-regulated cation entry across biological membranes. It is highly specific for divalent cations. Ion selectivity is as follows: Ca2+ > Mg2+ >> Sr2+ = Ba2+ Binding of Sr2+ and Ba2+ is insignificant and binding to monovalent cations or rubidium is negligible. La2+ is also bound to some extent. Complexation with a cation is always in a 1:1 stoichiometry and pH-dependent. Essentially no binding of Ca2+ occurs below pH 7.0 and maximum binding takes place at pH 9.5. At the micromolar level, ionomycin can activate Ca2+/Calmodulin dependent kinase and phosphatase to stimulate gene expression. Ionomycin has been shown to induce central demyelination, inhibit adrenal bovine TREK-1 channels, and to regulate cell division of mature human B cells [1]. It is used to study the effects of calcium flux on endoplasmic reticulum (ER) stress, mitochodrial stress and intrinsic apoptosis mechanisms. It is also used to stimulate the intracellular production of the cytokines, interferon, perforin, IL-2, and IL-4 usually in conjunction with PMA.

SP-420 is iron chelator developed by University Of Florida Research Foundation for the treatment of iron overload disease

Etripamil is a non-dihydropyridine, L-type calcium channel blocker. Currently, etripamil is in Phase 3 development for the treatment of paroxysmal supraventricular tachycardia. Milestone Pharmaceuticals is also developing etripamil to provide rapid heartbeat control for patients living with atrial fibrillation and acute symptom relief for patients with angina.

Nicametate is a vasodilator, which enhances blood flow and oxygen to the brain, aids stroke recovery. It also can use for treating intermittent claudication in certain patients.

FENIROFIBRATE, (-)- is a metabolite of fenofibrate, an antilipemic agent which reduces both cholesterol and triglycerides in the blood.
