Mycobacterium protein tyrosine phosphatase B (mPTPB) is essential for the survival and persistence of Mycobacterium in the host. Thus small molecule inhibitors of mPTPB are potential anti-TB agents. We developed an efficient organocatalytic multicomponent reaction (MCR) between pyrrole, formaldehyde and aniline, affording a potent and selective mPTPB inhibitor with an IC(50) value of 1.5 muM and >50-fold
分枝杆菌蛋白酪氨酸磷酸酶 B (mPTPB) 对分枝杆菌在宿主中的存活和持久性至关重要。因此,mPTPB 的小分子抑制剂是潜在的抗结核药物。我们在吡咯、甲醛和苯胺之间开发了一种高效的有机催化多组分反应 (MCR),提供了一种有效的选择性 mPTPB 抑制剂,IC(50) 值为 1.5 muM,特异性大于 50 倍。我们的研究提供了使用有机催化作为获取 PTP 抑制剂的发现工具的成功例子。
