It has been identified as an antagonist of chemokine receptor CCR5 binding (IC50 = 40 μM) to the envelope protein gp120 and to CD4, which is known to mediate HIV-1 viral entry into cells. Ophiobolin C is also reported to be cytotoxic to chronic lymphocytic leukemia cells (LC50 = 8 nM).
VerwendenOphiobolin C is a member of the ophiobolin class of phytotoxic metabolites produced by many species of the genus Bipolaris. Ophiobolin C inhibits human CCR5 binding to the envelope protein gp120 and CD4 that mediates HIV-1 entry into cells. Blockade of this binding was considered by scientists at Merck as a potential new mode of action for the treatment of HIV-1 infection.
