Structure−activity relationship studies were carried out by chemical modification of manzamine A (1), 8-hydroxymanzamine A (2), manzamine F (14), and ircinal isolated from the sponge Acanthostrongylophora. The derived analogues were evaluated for antimalarial, antimicrobial, and antineuroinflammatory activities. Several modified products exhibited potent and improved in vitro antineuroinflammatory, antimicrobial
构效关系研究是通过对曼扎明 A ( 1 )、8-羟基曼扎明A ( 2 )、曼扎明 F ( 14 ) 和从海绵棘圆线虫中分离的 ircinal 进行化学修饰来进行的。对衍生类似物的抗疟、抗微生物和抗神经炎症活性进行了评估。几种改良产品在体外表现出有效和改进的抗神经炎症、抗菌和抗疟活性。在多剂量和单剂量体内实验中,与氯喹相比,图1对疟疾的活性有所提高。小鼠疟疾的 100% 治愈率揭示了显着的抗疟潜力,一次给药 100 mg/kg 的1. Manzamines 的强效抗神经炎症活性将为预防和治疗脑部感染(例如,隐球菌和疟原虫)提供巨大的益处。此外,在使用 MDR-MDCK 单层的体外模型中,1显示可渗透穿过血脑屏障 (BBB)。对接研究支持2与糖原合成激酶-3β (GSK-3β) 的 ATP 非竞争性口袋结合,这是 manzamines 的推定目标。基于此处介绍的结果,将有可能围绕这种天然产物支
