aemanthamine (1m), revealed the most intriguing profile, both being acetylcholinesterase (hAChE) inhibitors on a micromolar scale, with GSK-3β inhibition properties, and predicted permeation through the BBB. In vitro data were further corroborated by detailed inspection of the compounds’ plausible binding modes in the active sites of hAChE and hBuChE, which led us to provide the structural determinants
开发了 12 种 1a-1m 的 β-crinane 型生物碱红花胺衍生物。研究了所有半合成衍生物对乙酰胆碱酯酶和丁酰胆碱酯酶的抑制潜力。此外,还评估了活性衍生物中糖原合酶激酶 3β (GSK-3β) 的抑制效力。为了揭示药物对 CNS 的可用性,我们阐明了所选衍生物穿透血脑屏障 (BBB) 的潜力。两种化合物,即 11-O-(2-甲基苯甲酰基)-haemanthamine (1j) 和 11-O-(4-nitrobenzoyl)-haemanthamine (1m),揭示了最有趣的特征,两者都是微摩尔浓度的乙酰胆碱酯酶 (hAChE) 抑制剂规模,具有 GSK-3β 抑制特性,并预测通过 BBB 的渗透。
