Cochlioquinone B, the minor component of a bioactive pigment isolated from Bipolaris leersia, is an NADH-ubiquinone reductase inhibitor and phytotoxic agent inhibiting root growth. It is closely related to Cochlioquinone A which inhibits diacylglycerol acyltransferase and exhibits anti-angiogenic and nematocidal activity. Cochlioquinones have recently been shown to be antagonists of the human chemokine receptor, CCR5, in HIV-1.
