Three new 10-membered macrolides (1-3) have been isolated from the entomopathogenic fungus Cordyceps militaris BCC 2816, together with six known compounds, cepharosporolides C (4), E (5), and F (6), 2-carboxymethyl-4-(3'-hydroxybutyl)furan (7), cordycepin (8), and pyridine-2,6-dicarboxylic acid. The structures were determined by analysis of NMR data, and an X-ray analysis was performed to confirm the structure of 1. The antimalarial activity of 1-4 and 8 against Plasmodium falciparum K1 was evaluated.
从昆虫病原真菌蛹虫草BCC 2816中分离出了三种新的十元大环内酯类化合物(1-3),以及六种已知化合物,即头孢菌素C(4)、E(5)和F(6)、2-羧甲基-4-(3'-羟基丁基)呋喃(7)、虫草素(8)和吡啶-2,6-二羧酸。通过核磁共振数据的分析确定了其结构,并进行了X射线分析以确认化合物1的结构。评估了化合物1-4和8对恶性疟原虫K1的抗疟活性。
