The search for selective kappa opioid receptor (κOR) agonists with an improved safety profile is an area of interest in opioid research. In this work, a series of m-substituted analogs were designed, synthesized, and assayed, resulting in the identification of compound 6c (SLL-1206) as a κOR agonist with single-digit nanomolar activities. The subtype selectivity of compound 6c appeared to be a consequence
寻找具有改进安全性的选择性κ阿片受体(κOR)激动剂是阿片类药物研究的一个感兴趣的领域。在这项工作中,设计、合成和分析了一系列m取代的类似物,最终鉴定出化合物6c ( SLL-1206 ) 作为具有个位数纳摩尔活性的 κOR 激动剂。化合物6c的亚型选择性似乎是对 μOR 和 δOR 的亲和力大幅降低的结果,而不是对 κOR 的亲和力显着增加的结果,而SLL-039 (另一种选择性有效的 κOR 激动剂)的情况并非如此。在我们之前的工作中已确定。除了减少中枢神经系统影响外,与SLL-039相比, SLL-1206还表现出显着改善的理化和药代动力学特性,在大鼠中的水溶性增加了 20 倍以上,口服生物利用度增加了约 40 倍。
