Simmiparib
Based on 1 Customer Validation
Simmiparib is a highly potent and orally active PARP1 and PARP2 inhibitor with IC50 values of 1.75 nM and 0.22 nM, respectively. Simmiparib has more potent PARP1/2 inhibition than its parent Olaparib (HY-10162). Simmiparib induces DNA double-strand breaks (DSB) accumulation and G2/M arrest in homologous recombination repair (HR)-deficient cells, thereby inducing apoptosis. Simmiparib exhibits remarkable anticancer activities in cells and nude mice bearing xenografts.

Simmiparib (0-10 μM; 3 days) exhibits anti-proliferative activity against various cancer cells[1].
Simmiparib (0-10 μM; 48 h) induces typical G2/M arrest in Capan-1 cells[1].
Simmiparib (0.1-2 μM; 24 h) induces apoptosis in MDA-MB-436 and V-C8 (BRCA2-/-) cells, and increases dose-dependently the levels of γH2AX[1].
Simmiparib (1-10 μM; 48 h or 72 h) increases the phosphorylation levels of Chk1 and Chk2 and the protein levels of p-Cyclin B1 (S147), Cyclin B1, p-CDK1 (Y15) and CDK1[1].
