Mechanism of Action

Targets/IC₅₀/Ki	PARP1 (in wild-type A549 lung cancer cells) 3 nM
In vitro	Saruparib (AZD5305) is a highly selective inhibitor for PARP1 over other PARP family members, with good secondary pharmacology and physicochemical properties and excellent pharmacokinetics in preclinical species. It reduces anti-proliferation effects on human bone marrow progenitor cells in vitro.
In vivo	Saruparib (AZD5305) is a potent and selective PARP1 inhibitor and PARP1–DNA trapper with excellent in vivo efficacy in a BRCA mutant HBCx-17 PDX model.
