and B are two recently isolated marine natural products with novel skeleton and exceptional biological profile. Interesting antiviral activity of nitrosporeusines and promising potential in curing various diseases, evident from positive data from various animal models, led us to investigate their anti-inflammatory potential. Accordingly, we planned and synthesized nitrosporeusines A and B in racemic as
亚硝基孢子碱A和B是最近分离的两种海洋天然产物,具有新颖的骨架和出色的生物学特性。从各种动物模型的积极数据中可以明显看出,亚硝基孢子碱有趣的抗病毒活性和治疗各种疾病的潜力,使我们研究了它们的抗炎潜力。因此,我们计划并合成了外消旋形式和对映体纯形式的亚硝基孢子碱A和B。在天然产物合成之后,制备了几种类似物,并评估了所有合成的化合物的体外和体内抗炎潜力。其中,化合物25、29和40显着降低了一氧化氮(NO),活性氧(ROS)和促炎细胞因子的水平。此外,这些化合物抑制了几种促炎性介质,包括诱导型一氧化氮合酶(iNOS),环氧合酶2(COX-2),核因子-κB(NF-κB),因此可以作为有效的消炎化合物出现。此外,在同一组测定中合成,表征和表征了铅化合物25的所有可能的异构体,发现其中一个对映异构体(-)-25a更好。
