Poly (ADP-ribose) polymerase (PARP) enzyme catalyzes the transfer of ADP-ribose into target proteins. Therefore, PARP is responsible for DNA repair, cell proliferation, and cell death. In this study, potential PARP enzyme inhibitors were designed and synthesized. The synthesized compounds were elucidated by Fourier-transform infrared spectroscopy, $^1}$H NMR, $^13}$C NMR, heteronuclear single-quantum correlation, and mass spectrometry, and their purity was checked via thin-layer chromatography, high-performance liquid chromatography, and elemental analysis. A total of 63 newly synthesized compounds were screened in terms of PARP inhibition by cellular PARylation assay in the HeLa cell line. It was found that 19 compounds significantly inhibited the H$_2}$O$_2}$-induced cellular PARylation. The chemosensitizer effect of these compounds in cancer cells treated with doxorubicin (doxo) was investigated. It was found that the combination of potent PARP inhibitors with doxo potentiated a cytotoxic effect, similar to that of olaparib. The results of the molecular docking and absorption, distribution, metabolism, excretion, and toxicity (ADMET) analysis revealed that compound 60 might be classified as a potential PARP inhibitor candidate. Taken together, all of the results suggested that carbohydrazide derivatives could be a promising lead for the treatment for cancer disorders.
聚(ADP-核糖)聚合酶(PARP)催化 ADP 核糖向目标蛋白质的转移。因此,PARP 负责 DNA 修复、细胞增殖和细胞死亡。本研究设计并合成了潜在的 PARP 酶抑制剂。通过傅立叶变换红外光谱、^1}$H NMR、^13}$C NMR、异核单量子相关分析和质谱分析对合成的化合物进行了阐明,并通过薄层色谱、高效液相色谱和元素分析检测了其纯度。通过在 HeLa 细胞系中进行细胞 PAR 化试验,筛选了 63 个新合成的化合物对 PARP 的抑制作用。结果发现,19 种化合物对 H$_2}$O$_2}$ 诱导的细胞 PAR 化有明显的抑制作用。研究了这些化合物在用多柔比星(doxo)处理的癌细胞中的化疗增敏作用。研究发现,强效 PARP 抑制剂与多柔比星(doxo)联用可增强细胞毒性效果,与奥拉帕利(olaparib)的效果类似。分子对接和吸收、分布、代谢、排泄和毒性(ADMET)分析的结果表明,化合物 60 可被列为潜在的 PARP 抑制剂候选药物。综上所述,所有这些结果表明,羧酰肼衍生物可能是治疗癌症疾病的一个很有前景的先导化合物。
