product (MNP) isolated from Aplidium meridianum. However, this compound has a moderate inhibitory activity toward GSK-3β (IC50 = 24.4 μM), moderate glucose uptake (38%), and especially, a low oral bioavailability (F = 11.4%). In the present study, applying the structure-based design strategy, a series of derivatives modified on the indole moiety were synthesized based on the lead compound I, followed
糖原合酶激酶 3β (GSK-3β) 已成为治疗糖尿病的有吸引力的靶点。化合物I是一种基于吲哚的 GSK-3β 抑制剂,由 Meridianin C 设计,Meridianin C 是一种从Aplidium meridianum中分离的海洋天然产物 (MNP) 。然而,该化合物对 GSK-3β 具有中等抑制活性(IC 50 = 24.4 μM),葡萄糖摄取中等(38%),尤其是口服生物利用度低(F = 11.4%)。在本研究中,应用基于结构的设计策略,在先导化合物I的基础上合成了一系列吲哚部分修饰的衍生物,随后评估了它们的细胞毒活性、抗高血糖活性和激酶抑制活性。在这个系列中,复合6x磺酰基在肌肉 L6 细胞中显示出最高的葡萄糖摄取 (83.5%),对 GSK-3β 显示出更高的抑制活性 (IC 50 = 5.25 μM)。分子对接表明,与化合物I (-6.950 kcal/mol)相比,化合物6x正确插入到
