further study the structure–activity relationship of gossypol, hemigossypol (1) and its derivatives (2–23) were successfully designed via structure simplification and chemically synthesized. The anti-tobacco mosaic virus (TMV), fungicidal, and insecticidal activities of them were tested systematically. Most of these derivatives exhibited excellent anti-TMV activity. Furthermore, these compounds also exhibited
为了进一步研究棉酚的结构-活性关系,hemigossypol(1)及其衍生物(2 - 23)被成功地通过结构的简化设计和化学合成。系统地测试了它们的抗烟草花叶病毒(TMV),杀真菌和杀虫活性。这些衍生物大多数表现出优异的抗TMV活性。此外,这些化合物还对14种植物致病真菌表现出广谱杀真菌活性。特别是,半胱氨酸酸内酯(7)在空气中稳定。就生物学活性而言,它不仅具有抗TMV活性(在500μg/ mL时对灭活,治疗和保护活性的抑制率分别为70.3、65.4和72.4%在体内)分别与宁南霉素相当,但与商品鱼藤酮相比,对蚊虫幼虫的杀虫活性更高(60%/ 0.25 mg / kg)。血吸虫酚和经测试的衍生物均未显示抗肿瘤活性。
