malachite green assay. RESULTS The results suggested that some of the compounds were found as non-selective inhibitors of isozyme of NTPDases, however, most of the compounds act as potent and selective inhibitors. In case of substituted amino derivatives (4c-m), the compounds 4m (IC50 = 1.13 ± 0.09 μM) and 4g (IC50 = 1.72 ± 0.08 μM) were found to be the most potent inhibitors of h-NTPDase1 and 2, respectively
背景外核苷三磷酸二磷酸水解酶(NTPDases)通过胞外5'-三磷酸核苷和5'-二磷酸核苷水解成5'-单磷酸核苷来终止核苷酸信号传导,并由8个依赖Ca2 + / Mg2 +的外切核苷酸酶(NTPDase1)组成。 -8)。细胞外核苷酸参与多种生理机制。然而,它们被胞外核苷酸酶快速灭活,该酶涉及从核苷酸中依次除去磷酸基团并释放出无机磷酸盐和它们各自的核苷。核苷三磷酸二磷酸二氢水解酶(NTPDases)代表负责核苷酸水解的关键酶,它们的过表达与某些病理状况有关。因此,NTPDase的抑制剂对于研究其治疗各种疾病(例如癌症,局部缺血以及其他心血管疾病和免疫系统疾病)的潜力特别重要。方法考虑到NTPDase抑制剂的重要性,通过孔雀石绿试验评估了一系列噻二唑并嘧啶酮对NTPDase的潜在抑制活性。结果结果表明,发现某些化合物是NTPDases同工酶的非选择性抑制剂,然而,大多数化合物是有效的和选择性
