GSK356278 1 is a potent, selective, and competitive inhibitor of PDE4 enzymes currently under investigation for the treatment of CNS disorders. The initial synthetic route developed by Medicinal Chemistry Department, used several hazardous and/or expensive reagents and harsh conditions and gave relatively low yields. By targeted process of research and development plus application of analytical techniques
磷酸二酯酶(PDE)酶家族水解环状核苷酸cAMP和cGMP,导致它们作为细胞内第二信使失活。这些酶的抑制导致细胞中环核苷酸水平的升高,并延长其对下游信号通路的作用。PDE4有四种亚型,在整个大脑中广泛表达,但在炎性和免疫细胞,胃肠道和心肌细胞的外周也丰富。GSK356278 1是目前正在研究中枢神经系统疾病治疗中的PDE4酶的强效,选择性和竞争性抑制剂。药物化学部门开发的最初的合成路线使用了几种危险和/或昂贵的试剂和苛刻的条件,收率相对较低。通过有针对性的研发过程以及分析技术的应用来识别副产物和广泛的路线筛选,已经开发出一种新颖的1合成路线。该贡献报告了1的化学合成的优化,以开发适合其合成的大规模工艺。
