Introduction of 1038915-58-0 :

Niraparib R-enantiomer (MK-4827 R-enantiomer) is an excellent PARP1 inhibitor with IC50 of 2.4 nM. IC50 & Target: IC50: 2.4 nM (PARP1)[1] In Vitro: Niraparib R-enantiomer (MK-4827 R-enantiomer) resolution of Niraparib R-enantiomer give compounds Niraparib R-enantiomer and Niraparib S-enantiomer, both showing excellent inhibition of PARP-1. Niraparib R-enantiomer has somewhat lower in vitro metabolic clearance than the Niraparib S-enantiomer in rat liver microsomes, but Niraparib S-enantiomer is more potent in cell based assays (PARylation EC50, Niraparib R-enantiomer=30 nM, Niraparib S-enantiomer=4.0 nM; BRCA1-HeLa CC50, Niraparib R-enantiomer=470, Niraparib S-enantiomer=34 nM). Given this improved potency and similar in vitro turnover in human liver microsomes (HLM Clint, Niraparib R-enantiomer=4, Niraparib S-enantiomer=3 μL/min/mgP), Niraparib S-enantiomer (Niraparib) is focused on[1].
