PARP1-IN-5 dihydrochloride

PARP1-IN-5 dihydrochloride is a low toxicity, orally active, potent and selective PARP-1 inhibitor (IC50 =14.7 nM). PARP1-IN-5 dihydrochloride can be used for the research of cancer[1].

PARP1-IN-5 dihydrochloride (0.1~10 μM; A549 cells) can significantly increase the cytotoxicity of CBP on A549 cells in a dose-dependent manner. PARP1-IN-5 dihydrochloride (0.1~10 μM; SK-OV-3 cells) decreases the expressions of MCM2-7. PARP1-IN-5 dihydrochloride (0.1~320 μM; A549 cells) has little cytotoxic effects on A549 cells. PARP1-IN-5 dihydrochloride (SK-OV-3 cells) can significantly decrease the PAR level[1].PARP1-IN-5 dihydrochloride exerts antitumor effects through PARP-1. PARP1-IN-5 dihydrochloride could increase the γ-H2AX expression[1].

PARP1-IN-5 dihydrochloride (1000 mg/kg; p.o.) shows that there is no significant difference in the body weight and blood routine[1].PARP1-IN-5 dihydrochloride (25 and 50 mg/kg; p.o.; 12 days) significantly enhances the inhibitory effect of carboplatin on A549 cells at 50 mg/kg[1].PARP1-IN-5 dihydrochloride (50 mg/kg; p.o.) positively correlates with the expression of PARP-1[1].PARP1-IN-5 dihydrochloride can upregulate the expression of γ-H2AX and decrease the expression of PAR[1].
