novo synthesis of deoxynucleotide triphosphates (dNTPs). Nucleoside analogues have been investigated as anticancer drugs that inhibit human RNR, however, problems with toxicity and cancer resistance remain challenging. Herein we report a convenient synthesis of six novel nucleoside analogues modified with benzenesulfonamide derivatives: 4-carboxybenzenesulfonamide, 4-chloro-3-sulfamoylbenzoic acid, 2
核糖核苷酸还原酶(RNR)是癌症化疗的关键靶点。该酶催化核糖核苷酸还原为 2'-脱氧核糖核苷酸,其活性在脱氧核苷酸三磷酸 (dNTP) 的从头合成中是限速的。核苷类似物已被研究作为抑制人类 RNR 的抗癌药物,然而,毒性和抗癌性问题仍然具有挑战性。在这里,我们报告了六种用苯磺酰胺衍生物修饰的新型核苷类似物的简便合成方法:4-羧基苯磺酰胺、4-氯代-3-氨磺酰苯甲酸、2-氯代-4-氟代-5-氨磺酰苯甲酸、2,3-二甲氧基-5-氨磺酰基苯甲酸,N-苄基-4-氯-5-氨磺酰邻氨基苯甲酸,或速尿。苯甲酸磺酰胺的羧基与尿苷的 5' 羟基之间的 Mitsunobu 反应以优异的产率产生了尿嘧啶基氨磺酰基苯甲酸酯。进行分子对接以检查与 RNR 的大亚基 M1 的构象和结合亲和力。氨磺酰基部分与催化位点中已知的底物结合残基如 Ser202 和 Thr607 显示出强氢键。吸电子氟和氯增强了结合,而给电子甲氧基降低了结合。计算机
