By imitating the scaffold of lithocholic acid (LCA), a natural steroidal compound displaying Protein Tyrosine Phosphatase 1B (PTP1B) inhibitory activity, a series of stilbene derivatives containing phenyl-substituted isoxazoles were designed and synthesized. The structures of the title compounds were confirmed by 1H-NMR, 13C-NMR and HRMS. Activities of the title compounds were evaluated on PTP1B and
通过模仿石胆酸 (LCA) 的支架,这是一种显示蛋白质酪氨酸磷酸酶 1B (PTP1B) 抑制活性的天然甾体化合物,设计并合成了一系列含有苯基取代的异恶唑的芪衍生物。标题化合物的结构经1H-NMR、13C-NMR和HRMS证实。标题化合物的活性通过使用比色法在 PTP1B 和同源酶 TCPTP 上进行评估。大多数目标化合物对 PTP1B 具有良好的活性。其中,化合物 29 (IC50 = 0.91 ± 0.33 μM) 具有 5-(2,3-二氯苯基)异恶唑部分,其活性比先导化合物 LCA 高约 14 倍,选择性比 TCPTP 高 4.2 倍. 在酶动力学研究中,化合物 29 被鉴定为 PTP1B 的竞争性抑制剂,Ki 值为 0.78 μM。
