relationship of NPP1 inhibitors based on acyclic uracil-nucleotides. For this purpose, we synthesized acyclic uridine-monophosphate analogs, 10-11, uridine-diphosphate analogs, 12-14, and uridine-Pα,α-dithio-triphosphate analogs, 15-17. We evaluated their inhibitory activity and selectivity towards NPP1, -3, NTPDase1, -2, -3, and -8, and P2Y2,4,6 receptors. Analogs 16 and 17 were the most selective and
胞外核苷酸焦磷酸酶-1(NPP1)的过表达与疾病相关,例如焦磷酸钙二水合物沉积疾病,钙化主动脉瓣疾病和2型糖尿病。在这种情况下,NPP1抑制剂可能是治疗这些疾病的潜在药物。本研究侧重于分析基于无环尿嘧啶核苷酸的NPP1抑制剂的构效关系。为了这个目的,我们合成了无环的尿苷-单磷酸酯类似物10-11,尿苷-二磷酸酯类似物12-14和尿苷-Pα,α-二硫代三磷酸酯类似物15-17。我们评估了它们对NPP1,-3,NTPDase1,-2,-3和-8以及P2Y2,4,6受体的抑制活性和选择性。在测试分子中,类似物16和17是最有选择性和最有效的NPP1抑制剂(分别为Ki 0.94和0.73μM)。类似物10-17对尿嘧啶核苷酸应答的P2Y2,4,6受体只有微小的作用。类似物17(100μM)在骨关节炎人软骨细胞中显示出96%的NPPase活性抑制。类似物14-17在人软骨细胞中等摩尔浓度下显示出对碱
