diseases, allergies, and cancer metastasis. A new series of sulphonate derivatives was synthesized and tested against the isozymes NPP1 and NPP3. The compound 4q was found as the more active and comparatively selective inhibitor of the isozyme NPP1 with IC50 ± SEM = 1.97 ± 0.03 μM vs. NPP3 whereas, the compound 4n was a potent and moderately selective inhibitor of NPP3 (IC50 ± SEM = 0.85 ± 0.04 μM). The
核苷酸焦磷酸酶/磷酸二酯酶 (NPP) 水平升高与软骨钙质沉着症、骨关节炎、2 型糖尿病、神经退行性疾病、过敏和癌症转移有关。合成了一系列新的磺酸盐衍生物,并针对同工酶 NPP1 和 NPP3 进行了测试。发现化合物4q是同工酶 NPP1 的活性更高且选择性相对较高的抑制剂,IC 50 ± SEM = 1.97 ± 0.03 μM 与 NPP3 相比,而化合物4n是一种有效且中等选择性的 NPP3 抑制剂(IC 50 ± SEM = 0.85 ± 0.04 微米)。化合物4c、4e、4f、4j和7b有效阻断 NPP1 和 NPP3 的活性,IC 50亚微摩尔水平的值。通过 MTT 试验测试,这些化合物对 MCF-7 或 HeLa 癌细胞活力的影响可以忽略不计。所选抑制剂的分子对接研究显示与 NPP1 结晶蛋白的 Thr256、Asn277、Leu290、His380 和 Lys255 残基具有强结合键,而与
