tetronic acid derivatives were synthesized and evaluated as inhibitors of the dual-specificity protein phosphatases VHR and cdc25B. Several compounds are found to be potent inhibitors of cdc25B, which is a key enzyme for cell-cycle progression. The promising results described herein strongly indicated that this tetronic acid library is potent as a library focused on the PTP/DSP-selective inhibitor.
蛋白质酪氨酸磷酸酶(PTPs)和双特异性磷酸酶(DSPs)的选择性抑制剂有望成为阐明PTPs自身生物学功能的有用工具,并且有望成为新型疗法的候选者。我们计划了一种用于鉴定PTP / DSP抑制剂的文库方法,其中将3-酰基teonic酸用作“核心”磷酸盐模拟物。合成了一系列新颖的tetronic酸衍生物,并评估了其为双特异性蛋白磷酸酶VHR和cdc25B的抑制剂。发现几种化合物是cdc25B的有效抑制剂,cdc25B是细胞周期进程的关键酶。本文所述的有希望的结果有力地表明,该tetronic酸文库作为专注于PTP / DSP选择性抑制剂的文库是有效的。
