Pharmacology
Aromatase inactivator; exemestane is an irreversible steroidal aromatase inactivator that acts as a false substrate for the aromatase enzyme, binding irreversibly to the active site ('suicide inhibition') and significantly lowering circulating estrogen concentrations in postmenopausal women without affecting adrenal corticosteroid or aldosterone biosynthesis.
Abemaciclib is an inhibitor of cyclin-dependent kinases 4 and 6 (CDK4/6); in ER-positive breast cancer cells, it blocks Rb phosphorylation and cell cycle progression from G1 into S phase, resulting in senescence and apoptosis.
