Effects of 5-acetyl(carbamoyl)-6-methylsulfanyl-1,4-dihydropyridine-5-carbonitriles on rat liver mitochondrial function.

It is increasingly recognised that mitochondria are potential targets to pharmacological and toxicological actions of membrane-active agents, including some 1,4-dihydropyridines derivatives (DHPs). The 5-acetyl(carbamoyl)-6-methylsulfanyl-1,4-dihydropyridine-5-carbonitriles (OSI-1146, OSI-3701, OSI-3761, and OSI-9642) is a new group of DHPs with minor differences on the molecular structure. It has also been shown that OSI-1146 displays cardiovascular, antioxidant, and antiradical activities, whereas OSI-3701 and OSI-3761 display hepatoprotective activity.
