  • Berberine activates PARP1 in ovarian cancer cells. PAR synthesis is detected by immunofluorescence staining in A2780 and HO8910 treated with different concentration of berberine alone or in combination with niraparib (10 μM) for 48 h. Top: representative examples of immunofluorescence staining of PAR. Scale bar, 20 μm. Bottom: quantification of PAR level in A2780 and HO8910. Immunofluorescence intensities were quantified by ImageJ. *P<0.05, **P<0.01

Biological Activity

Description Niraparib (MK-4827) tosylate is a selective inhibitor of PARP1/PARP2 with IC50 of 3.8 nM/2.1 nM.
Targets
PARP2 [3]
(Cell-free assay)		 PARP1 [3]
(Cell-free assay)
2.1 nM 3.8 nM
In vitro

Micromolar concentrations of niraparib radiosensitizes tumor cell lines derived from lung, breast, and prostate cancers independently of their p53 status but not cell lines derived from normal tissues. Niraparib also sensitizes tumor cells to H2O2 and converts H2O2-induced single strand breaks (SSBs) into DSBs during DNA replication[5].

In vivo MK-4827 strongly enhances the effect of radiation on a variety of human tumor xenografts, both p53 wild type and p53 mutant. MK-4827 reduces PAR levels in tumors by 1 h after administration which persisted for up to 24 h[1]. In vivo treatment with MK-4827 and radiation prolonged survival (p<0.01) compared to single modalities. In vivo superiority of MK-4827 plus radiation is further documented by significant elevations of cleaved caspase-3 and γ-H2AX in tumors from the combination group compared to single modality cohorts[4].
