identification of a series of purines as selective CB2 agonists and the identification of compound 1 as a clinical candidate for the treatment of joint pain. In this article we describe the further SAR development of the purine scaffold leading to the discovery of compound 6 as a potent, CNS penetrating CB2 agonist with high selectivity for CB2 over CB1 and oral efficacy in animal models of chronic OA
骨关节炎(OA)和相关的关节痛非常普遍,并且是导致残疾的主要原因。先前我们已经报道了一系列嘌呤作为选择性CB2激动剂的鉴定,以及化合物1作为关节痛治疗的临床候选物的鉴定。在本文中,我们描述了嘌呤支架的SAR进一步发展,导致发现了化合物6作为一种强效的CNS穿透性CB2激动剂,对CB2的选择性高于CB1,并且在慢性OA疼痛动物模型中具有口服功效。
