Anticancer activity of Ophiobolin A, isolated from the endophytic fungus Bipolaris setariae.

The present work describes the anticancer activity of Ophiobolin A isolated from the endophytic fungus Bipolaris setariae. Ophiobolin A was isolated using preparative HPLC and its structure was confirmed by HRMS, (1)H NMR, (13)C NMR, COSY, DEPT, HSQC and HMBC. It inhibited solid and haematological cancer cell proliferation with IC50 of 0.
