Abstract

Gossypol, a polyphenolic binaphthalene dialdehyde isolated from cotton meal is a potent inhibitor of lactate dehydrogenase-X purified from bovine testis. For the conversion of pyruvate to lactate the IC50for gossypol is 200 μM for the reverse reaction the IC50is 12 μM. Gossypol is a competitive inhibitor of NADH, Ki = 30 μM (Km = 17 μM), and NAD+, Ki = 6 μM (Km = 130 μM), and noncompetitive for pyruvate, Ki = 220 μM (Km = 224 μM), and lactate, Ki = 52 μM (Km = 5.6 mM). © 1983.
