Pharmacology
Talazoparib is an inhibitor of PARP enzymes (PARP1 and PARP2) involved in DNA repair; it induces cytotoxicity in cancer cells with DNA repair gene defects through inhibition of PARP enzymatic activity and increased formation of PARP-DNA complexes, resulting in DNA damage, decreased cell proliferation, and apoptosis.
Anastrozole is a selective non-steroidal aromatase inhibitor that suppresses estrogen biosynthesis by blocking the aromatase enzyme, significantly lowering serum estradiol concentrations in postmenopausal women without affecting adrenal corticosteroid or aldosterone formation.
