their binding affinities for the human A(2B), A(1), A(2A), and A(3) adenosine receptors. N-(4-chloro-phenyl)-2-[3-(2,6-dioxo-1,3-dipropyl-2,3,6,7-tetrahydro-1H-purin-8-yl )-5-methyl-pyrazol-1-yl] (11c) showed a high affinity for the human A(2B) adenosine receptor K(i)=7nM and good selectivity (A(1), A(2A), A(3)/A(2B)>140). Synthesis and SAR of this novel class of compounds is presented herein.
一个新的系列的1,3-二丙基-8-(1-苯基乙酰胺-1H-吡唑-3-基)-黄嘌呤衍生物已被确定为有效的A(2B)腺苷受体拮抗剂。已评估产品对人A(2B),A(1),A(2A)和A(3)腺苷受体的结合亲和力。N-(4-氯-苯基)-2- [3-(2,6-二氧代-1,3-二丙基-2,3,6,7-四氢-1H-嘌呤-8-基)-5-甲基-pyrazol-1-yl](11c)对人A(2B)腺苷受体K(i)= 7nM具有高亲和力,并且具有良好的选择性(A(1),A(2A),A(3)/ A( 2B)> 140)。本文介绍了这类新型化合物的合成和SAR。
