title: Dicarbanonaborates--new inhibitors of mitochondrial L-glycerol-3-phosphate dehydrogenase.
abstract: The inhibitory effect of mercapto- and chlorodicarbanonaborates on mitochondrial, FAD-linked, L-glycerol-3-phosphate dehydrogenase activity was tested. The mercaptodicarbanonaborate was found to be a more potent inhibitor than the chloro derivative. The Ki of mercapto- and chlorodicarbanonaborates were 0.8 M and 480 M, respectively. Whereas the mercaptodicarbanonaborate inhibited the enzyme activity competitively, the inhibitory effect of chloro derivative was noncompetitive. The inhibitory effect of mercaptodicarbanonaborate was completely prevented by addition of bovine serum albumin.
