describe the discovery of a novel class of oxadiazole derivatives from which potent and selective CB2 agonist leads were developed. Initial hit 7 was identified from a cannabinoid target-biased library generated by virtual screening of sample collections using a pharmacophore model in combination with a series of physicochemical filters. 7 was demonstrated to be a selective CB2 agonist (CB2 EC50 = 93
CB2受体是止痛药和抗炎药的有吸引力的治疗靶标。在本文中,我们描述了发现一类新的恶二唑衍生物的发现,由此开发了有效的和选择性的CB2激动剂。通过使用药效团模型结合一系列物理化学过滤器对样品集合进行虚拟筛选,从大麻靶偏倚的文库中识别出最初的第7个匹配项。7被证明是选择性CB2激动剂(CB2 EC50 = 93 nM,Emax = 98%,CB1 EC50> 10 microM)。但是,该化合物在大鼠中表现出较差的溶解性和相对较高的清除率,导致口服生物利用度低。在本文中,我们报告了有关提高功效,理化性质和溶解度的7条途径的详细SAR研究。
