cannabinoid-1 receptor (CB1R) inverse agonist SR141716A has proven useful for study of the endocannabinoid system, including development of divalent CB1R ligands possessing a second functional motif attached via a linker unit. These have predominantly employed the C3 position of the central pyrazole ring for linker attachment. Despite this precedent, a novel series of C3-linked CB1R-D2R divalent ligands exhibited
大麻素1受体(CB1R)反向激动剂SR141716A已被证明可用于研究内源性大麻素系统,包括开发具有通过连接单元连接的第二个功能性基序的二价CB1R配体。这些主要使用中央吡唑环的C3位连接接头。尽管有这个先例,但是一系列新颖的C3连接的CB1R-D2R二价配体对D2R表现出极高的亲和力,但对CB1R的亲和力却很差。因此,对SR141716A药效团进行了系统的连接子连接点调查,确定了C5位置为连接子缀合的最佳位点。这项连接子附着调查使我们能够鉴定出一种新的二价配体作为先导化合物,以指导正在进行的高亲和力CB1R分子探针的开发。
