0.5 nM and excellent selectivity (>4000-fold) over the CB1 receptor. The size of the substituent on the 2-position determined the level of agonism, ranging from inverse agonism to partial agonism to full agonism, which was more pronounced for the rat CB2 receptor. A wide variation of sulfonyl substituents at the benzimidazole 5-position was tolerated, which was used to optimize the drug-like properties
合成了一系列新的苯并咪唑CB2-受体激动剂,并探讨了其构效关系。结果显示激动作用与高达0.5 nM的EC(50)和比CB1受体优异的选择性(> 4000倍)。2位上取代基的大小决定了激动水平,范围从反向激动到部分激动到完全激动,这对于大鼠CB2受体更为明显。苯并咪唑5-位的磺酰基取代基的宽泛变化是可以容忍的,这被用来优化类药物性质。这产生了铅化合物14j,其可用于研究选择性的,具有周边作用的CB2激动剂的潜力。使用饼状图(VlaaiVis)显示关键化合物的体外概况。
