to platelet aggregation, and selective antagonists are sought as potential antithrombotic agents. We reported (Kim et al. J. Med. Chem. 2000, 43, 746-755) that acyclic analogues of adenine nucleotides, containing two phosphate groups on a symmetrically branched aliphatic chain, attached at the 9-position of adenine, are moderately potent P2Y1 receptor antagonists. In this study we have varied the chain
血小板中 P2Y1 受体的激活有助于血小板聚集,因此寻求选择性拮抗剂作为潜在的抗血栓剂。我们报道 (Kim et al. J. Med. Chem. 2000, 43, 746-755) 腺嘌呤核苷酸的无环类似物,在对称支链脂肪链上含有两个磷酸基团,连接在腺嘌呤的 9 位强效 P2Y1 受体拮抗剂。在这项研究中,我们改变了链结构,包括不对称取代、烯属和环丙基。这些拮抗剂在微摩尔范围内抑制由 30 nM 2-MeS-ADP 诱导的火鸡红细胞膜中的磷脂酶 C 的刺激。在被两个磷酸基团取代的一系列对称支化脂肪族基团中,最佳拮抗剂效力发生在 2-甲基丙基基团。2-氯-N(6)-甲基腺嘌呤衍生物,2-[2-(2-chloro-6-methylaminopurin-9-yl)methyl]propane-1,3-bisoxy(diammoniumphosphate) (7),是一个完整的P2Y1 受体拮抗剂,IC(50)
