Six new oxygenated daphnane-type diterpenoids, trigoxyphins A-F (1-6), a phenanthrene-type diterpenoid, trigoxyphin G (7), and two known compounds were isolated from twigs of Trigonostemon xyphophylloides. Their structures were established using spectroscopic methods. Compounds 1 and 2 exhibited strong cytotoxic activity against HL60 (IC(50): 0.27 and 0.49 microM) and A549 (IC(50): 7.5 and 4.9 microM) tumor cell lines, respectively.
从细子龙(Trigonostemon xyphophylloides)的嫩枝中分离得到了 6 个新的含氧达玛烷型二萜类化合物,即 trigoxyphins A-F(1-6),一个菲型二萜类化合物 trigoxyphin G(7),以及 2 个已知化合物。通过光谱方法确定了它们的结构。化合物 1 和 2 对 HL60(IC(50):0.27 和 0.49 μM)和 A549(IC(50):7.5 和 4.9 μM)肿瘤细胞系表现出较强的细胞毒性。
