Phidianidines A和B是两种新的海洋吲哚生物碱,具有多种生物活性。我们先前的研究表明,合成的phidianidine类似物具有抑制蛋白酪氨酸磷酸酶1B(PTP1B)活性的潜力,PTP1B是II型糖尿病的有效靶点,这表明这些类似物值得进一步结构修饰。因此,本论文采用功能导向合成(FOS)策略,设计并快速合成了一系列菲双苯胺衍生物。它们对PTP1B和T细胞蛋白酪氨酸磷酸酶(TCPTP)的抑制作用进行了评价,并显示出显着的抑制效力和特定的选择性超过PTP1B的化合物。还描述了构效关系(SAR)和分子对接分析。
Phidianidines A and B are two novel marine indole alkaloids bearing an uncommon 1,2,4-oxadiazole ring and exhibiting various biological activities. Our previous research showed that the synthesized phidianidine analogs had the potential to inhibit the activity of protein tyrosine phosphatase 1B (PTP1B), a validated target for Type II diabetes, which indicates that these analogs are worth further structural modification. Therefore, in this paper, a series of phidianidine derivatives were designed and rapidly synthesized with a function-oriented synthesis (FOS) strategy. Their inhibitory effects on PTP1B and T-cell protein tyrosine phosphatase (TCPTP) were evaluated, and several compounds displayed significant inhibitory potency and specific selectivity over PTP1B. The structure–activity relationship (SAR) and molecular docking analyses are also described.
