摘要 | Poly (ADP-ribose) polymerase (PARP) is a family of enzymes that play an important role in DNA repair. We designed 2-(2,3,6-tribromo-4,5-dimethoxybenzylidene) hydrazinecarbothioamide (BTH-8) as a novel human PARP (PARP-1) inhibitor with anticancer activities in vitro and in vivo. With an IC50 value of 79.79 +/- 2.16 nM, BTH-8 caused DNA double-strand breaks, increased the foci quantitation of gamma-H2AX and inhibited poly(ADP-ribose) (PAR) formation. BTH-8 could bind to PARP-1 with the target affinity [KD (equilibrium dissociation constant) value] of 1.372 mu M. BTH-8 can inhibit the proliferation of a variety of tumor cells, especially BRCA-deficient cells (HCC-1937 and Capan-1). Further investigation showed that BTH-8 effectively induced a significant amount of G2/Mcell cycle arrest and cell apoptosis in HCC-1937 cells. BTH-8 also exhibited antitumor activity in vivo, which was achieved by the inhibition of PARP-1. In sum, our study indicates that BTH-8 might be a novel suitable PARP-1 inhibitor to treat human breast cancer. (C) 2020 Elsevier B.V. All rights reserved. |
