描述 | PARP1, also called as Poly(ADP-ribose) polymerase, is involved in the signaling of DNA damage. It can recognize and bind DNA single or double-strand breaks, thus possessing various cellular function, including regulation of apoptosis and chromosome stability, gene amplification and transcription, as well as cell division and differentiation. PARP-2 is the closest homolog of PARP1 (~62% similarity in catalytic domain) and compensates for PARP-1 activity in DNA single-strand break. MK-4827 is potent inhibitor of PARP1 and PARP2 with IC50 values of 3.8nM and 2.1nM (measured by PARP isoform TCA assays), respectively, at least a 100-fold selectivity over PARP-3, V-PARP, and tankyrase-1. MK-4827 inhibited PARP activity with EC50 of 4nM and preferentially suppressed proliferation of MDA-MB-436 cells carrying BRCA-1 mutation with CC50 value of 18nM and CAPAN-1 cells carrying BRCA-2 mutantation with CC50 value of 90nM. Oral treatment with MK-4827 at either 100 mg/kg q.d. or 50 mg/kg b.i.d. for 33 days repressed tumor growth in a BRCA-1 mutant MDA-MB-436 xenograft model[1].Oral administration of MK-4827 at a dose of 50mg/kg once daily radiosensitized all four tumors regardless of the p53 status, including Calu-6, H460, A549 and MDA-MB-231, with reduced PAR levels in tumors[2]. |
作用机制 | MK-4827 is a nicotinamide derivate, which can compete with NAD+ for the PARP catalytic site.[3] |
