Fosmenic acid was used for the treatment of atherosclerosis. Information about the current use of this drug is not available.

Flindokalner (BMS 204352; MaxiPost™) is a neuroprotective agent with potential in the treatment of stroke developed by Bristol-Myers Squibb. Flindokalner is a potent and effective opener of two important subtypes of neuronal potassium channels, the calcium-activated, big-conductance potassium channels (K(Ca) channels) and voltage-dependent, non-inactivating potassium channels known as KCNQ channels. Flindokalner significantly reduced cortical infarct volume in a animal models of stroke. Flindokalner failed to show superior efficacy in acute stroke patients compared to placebo in a Phase III study.

Carboxyamidotriazole (L651582) is a carboxyamide-amino-imidazole compound originally developed as a coccidiostat, an antiprotozoal agent that acts upon Coccidia parasites. Carboxyamidotriazole (L651582) is an orally-active agent with potential antineoplastic activity. Carboxyamidotriazole binds to and inhibits non-voltage-operated Ca2 channels, blocking both Ca2 influx into cells and Ca2 release from intracellular stores and resulting in the disruption of calcium channel-mediated signal transduction and inhibition of vascular endothelial growth factor (VEGF) signaling, endothelial proliferation, and angiogenesis. This agent may also inhibit tumor cell growth, invasion, and metastasis.

Oxiniacic Acid is a nicotinic acid derivative, that shows potent hypolipidemic activity.

Yohimbinic acid, also known as yohimbic acid is an indole alkaloid, which was isolated from dried roots of Rauwolfia serpentina. Yohimbinic acid is a potent inhibitor of a human DNA Topoisomerase I and can inhibit cancer cells growth.

Salclobuzate sodium was developed as an oral absorption promoter. This compound had to “chaperone” poorly permeable payloads across the intestine. Information about the current use of this compound is not available.

Atrasentan (ABT-627, A-127722) is a selective endothelin A receptor antagonist. Atrasentan is being developed by AbbVie as an oral treatment for diabetic nephropathies.Abbott Laboratories was conducting clinical development of atrasentan for the treatment of certain cancers, including phase II trials for prostate cancer. However, no recent development has been reported for cancer indications and development is presumed to be discontinued.
