are known to be endowed with CCR8 agonistic activity, systematic structure-activity relationship studies have not been reported. In this study, ZK756326, a previously disclosed CCR8 agonist, was divided in various fragments and each subunit was subjected to structural modifications. All newly synthesized analogues were evaluated in a CCR8 calcium mobilization assay, revealing that only limited structural
CCR8 激动剂有望治疗各种自身免疫性疾病。尽管已知苯氧基苄基哌嗪衍生物具有CCR8激动活性,但系统的构效关系研究尚未见报道。在这项研究中,ZK756326,一种先前公开的CCR8激动剂,被分成不同的片段,并且每个亚基都进行了结构修饰。所有新合成的类似物均在 CCR8 钙动员测定中进行了评估,结果表明苯环和苄位仅允许有限的结构变化。相比之下,各种接头给出的类似物具有良好的 CCR8 激动效力。此外,哌嗪基部分上小取代基的存在或哌嗪基与哌啶基的交换提供了具有前景的CCR8激动剂的化合物,其中最有效的同系物比ZK756326强10倍。
