OPHIOBOLIN A Chemical Properties,Uses,Production
Description
Ophiobolin A (4611-05-6) selectively inhibits the growth of cancer cells (IC50=0.4-4.3 μM) over normal cells (IC50=20.9 μM).1 Induces non-apoptotic cell death in glioblastoma cells and is active in an in vivo model.2 Covalently reacts with primary amines such as lysine side chains2 and phosphatidylethanolamine3 forming unique pyrrole adducts. Induces ER stress4, paraptosis4 and autophagy5.
Uses
Ophiobolin A is the dominant member of a class of phytotoxic metabolites produced by plant pathogenic fungi. Ophiobolin A acts by inhibiting calmodulin action in calcium regulation.
Definition
ChEBI: A sesterterpenoid that is ophiobolane with a hydroxy group at position 3, oxo groups at positions 5 and 25, double bonds at positions 7-8 and 19-20, and an oxygen link between positions 14 and 18.
