Biological Activity

Simmiparib is a novel potent, orally active PARP1/2 inhibitor with IC50 of 1.75/0.22 nM, inhibits PARP1 >90-fold more potently than the other PARPs (PARP3, TNKS1, TNKS2).
Simmiparib selectively induces the accumulation of DNA double-strand breaks, G2/M arrest and apoptosis in homologous recombination repair (HR)-deficient cells.
Simmiparib potentiates the proliferative inhibition of several conventional anticancer drugs, reduces the poly(ADP-ribose) formation in HR-deficient cancer cells and xenografts.
Simmiparib exhibits 10-fold greater growth inhibition than olaparib against HR-deficient human cancer cell- or tissue-derived xenografts in nude mice.
