derivatives of dephostatin, a protein tyrosine phosphatase (PTPase) inhibitor, to study the structure-activity relationships of this inhibitor. Inactive analogs revealed some insight into structural requirements or PTPase inhibitory activity of dephostatin. Both a nitroso group and phenolic hydroxyl groups were found to be essential for the inhibitory activity. Among the dephostatin derivative synthesized
我们已经合成了一种蛋白质酪氨酸磷酸酶(PTPase)抑制剂去磷酸他汀的衍生物,以研究该抑制剂的构效关系。非活性类似物揭示了对去磷酸他汀的结构要求或PTPase抑制活性的一些了解。发现亚硝基和酚羟基对于抑制活性都是必需的。在合成的去磷他汀衍生物中,一种去磷他汀的区域异构体显示出与去磷他汀相同的PTPase抑制活性,并且具有增加的稳定性。
