New iridoid glycoside derivatives from durantoside I, the latter from the dried flowers and leaves of Citharexylum spinosum, were synthesized by variously modifying a sugar moiety by silylation or acetylation and/or removal of cinnamate group at C-7 position and subsequent screening for comparative cytotoxicity against several cancer cell lines. Addition of alkylsilane to durantoside I and removal of cinnamate group were most effective in improving cytotoxicity.
从刺桐（Citharexylum spinosum）干燥的花和叶中提取的杜兰糖苷I合成了新的环烯醚萜苷衍生物，通过硅烷化或乙酰化对糖部分进行各种修饰和/或去除C-7位的肉桂酸酯基团，随后筛选其对几种癌细胞系的比较细胞毒性。向杜兰糖苷I中添加烷基硅烷和去除肉桂酸酯基团对提高细胞毒性最为有效。
