Biochemicals Storage: +4CShipping: Blue Ice
Cochlioquinone B, the minor component of a bioactive pigment isolated from Bipolaris leersia, is an NADH-ubiquinone reductase inhibitor and a phytotoxic agent inhibiting root growth. It is closely related to Cochlioquinone A that inhibits diacylglycerol acyltransferase and exhibits anti-angiogenic and nematocidal activity. Cochlioquinones have been recently shown to be antagonists of the human chemokine receptor CCR5 in human immunodeficiency virus type 1 (HIV-1).
