The first semisynthesis and biological profiling of the new abietane diterpenoid (+)-liquiditerpenoic acid A (abietopinoic acid) (7) along with several analogues are reported. The compounds were obtained from readily available methyl dehydroabietate (8), which was derived from (-)-abietic acid (1). Biological comparison was conducted according to the different functional groups, leading to some basic
报道了新的松果二萜二萜类(+)-液体亚甲烯酸A(花生四烯酸)(7)和几种类似物的首次半合成和生物学分析。所述化合物获自易得的脱氢松香酸甲酯(8),其衍生自(-)-松香酸(1)。根据不同的官能团进行了生物学比较,从而得出了一些基本的构效关系(SAR)。特别是,铁氧还蛋白和糖醇类似物7和10-16的特征是存在乙酰化的酚基部分,被氧化的C-7为羰基以及在C-18处具有不同的官能团(甲氧基羰基,羧酸和羟甲基)。针对一组六种代表性人类肿瘤固相细胞(A549,HBL-100,HeLa,SW1573,T-47D和WiDr),五种白血病细胞模型(NALM-06,KOPN-8,SUP-B15,UoCB1和BCR-ABL)和四种利什曼原虫种(婴儿乳杆菌,多诺尼乳杆菌,亚马逊乳杆菌,和古安湖(L. Guyanensis)。一项分子对接研究指出了这些利什曼原虫物种的一些目标。另外,还报道了化合物调节GABAA受体
