An imidazo[1,2-a]pyridine series of ATX inhibitors was identified out of a high-throughput screening (HTS). A cocrystal structure with one of these compounds and ATX revealed a novel binding mode with occupancy of the hydrophobic pocket and channel of ATX but no interaction with zinc ions of the catalytic site. Exploration of the structure–activity relationship led to compounds displaying high activity
Autotaxin(ATX)是一种分泌的酶,在血液中通过溶血磷脂酰胆碱(LPC)的水解在溶血磷脂酸(LPA)的生产中起主要作用。ATX-LPA信号转导引起了药物开发行业的高度关注,因为它已涉及多种疾病,包括癌症,纤维化疾病和炎症等。咪唑[1,2- a从高通量筛选(HTS)中鉴定出ATX抑制剂的]吡啶系列。这些化合物之一与ATX的共晶结构揭示了一种新型的结合模式,占据了ATX的疏水口袋和通道,但与催化位点的锌离子没有相互作用。对结构-活性关系的探索导致化合物在生化和血浆分析中显示出高活性,例如化合物40。口服给予大鼠后,化合物40还能够降低血浆LPA水平。
