(Orchidaceae), exhibits anticancer activity. Surprisingly, this natural product has not been evaluated for any other biological activity so far. To discover other novel potential of Cephalandole A 2, an efficient and economic synthetic protocol for novel Cephalandole A analogues 21a-o has been developed, in only 3 steps from using indole, and applied for their biological activity. Biological testing showed
Cephalandole A 2是一种小吲哚生物碱,该生物碱是从台湾兰花小头草(Orphadaceae)分离而来的,具有抗癌活性。出人意料的是,至今尚未对该天然产物进行任何其他生物学活性的评估。为了发现头孢兰醇A 2的其他新颖潜力,从使用吲哚仅三步就开发了新颖且有效的头孢兰醇A类似物21a-o的合成方案,并对其生物活性进行了应用。生物学测试表明,头孢烯二酚A 2及其新型类似物21a-o在初步测定中显示出潜在的抗微生物和抗血小板活性。据我们所知,这是头孢菌素A 2及其新型合成类似物21a-o作为新型抗菌剂和抗血小板剂的首次报道。在这项研究中,2和其他类似物即 ,21b,21d,21i和21o显示出对植物病原性细菌和真菌的有希望的抗菌活性。头孢兰酯A 2、21c,21f和21i也显示出有效的抗血小板活性。
