Obtusifoliol is a specific CYP51 inhibitor, Obtusifoliol shows the affinity with K d values of 1.2 µM and 1.4 µM for Trypanosoma brucei (TB) and human CYP51 , respectively In Vitro Obtusifoliol (0.1-100 µM; 48 hours) inhibit MCF-7 and MDA-MB231 breast cancer cells proliferation via arresting cell cycle progression and induction of apoptosis. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
