Anibamine, a novel pyridine quaternary alkaloid isolated from Aniba sp., was found to effectively compete with 125I-gp120 in binding to the chemokine receptor CCR5, with an IC50 = 1 μM. Anibamine is the first natural product reported as a CCR5 antagonist, and thus provides a novel structural skeleton unique from other lead compounds that have generally been identified from high-throughput screening efforts
最近的研究表明,CCR5趋化因子受体可能是治疗前列腺癌的潜在靶标。因此,CCR5拮抗剂的开发可以提供新颖的前列腺癌治疗方法。发现Anibamine是一种从Aniba sp。分离的新型吡啶季生物碱,其与趋化因子受体CCR5的结合可有效与125 I-gp120竞争,其IC 50为50 = 1μM。茴香胺是第一个被报道为CCR5拮抗剂的天然产物,因此提供了一种不同于其他先导化合物的新颖结构骨架,而这些先导化合物通常是从高通量筛选工作中鉴定出来的。为了改善先导化合物的结构并提高阿尼巴胺衍生物作为潜在的抗前列腺癌药物的治疗指数,在这项工作的结构-活性关系研究中采用了“解构-重建-精制”的方法。在这里,我们报告阿尼巴明和17类似物的设计,合成和抗前列腺癌活性。从结果在体外和体内在此描述的研究表明,这类化合物有潜力提供新颖的引线作为抗前列腺癌试剂。
