Protein kinase B (PknB) is an essential serine/threonine protein kinase required for Mycobacterium tuberculosis (M. tb) cell division and cell-wall biosynthesis. A high throughput screen using PknB identified a (E)-4-oxo-crotonic acid inhibitor, named YH-8, which was used as a scaffold for SAR investigations. A significant improvement in enzyme affinity was achieved. The results indicated that the
蛋白激酶B(PknB)是结核分枝杆菌(M. tb)细胞分裂和细胞壁生物合成所必需的丝氨酸/苏氨酸蛋白激酶。使用PknB进行的高通量筛选鉴定出一种名为YH-8的(E)-4-氧代巴豆酸抑制剂,该抑制剂被用作SAR研究的支架。实现了酶亲和力的显着改善。结果表明,α,β-不饱和酮骨架和“反式”构型对于对抗PknB的活性至关重要。而且具有芳基的化合物,特别是在苯环上具有吸电子取代基的化合物,其效能是YH-8的四倍。
