Nineteen new derivatives (2—20) of the naturally occurring compound, goniothalamin (1), were prepared by chemical modification and semi-synthetic methods. The antitumor activities of these derivatives and goniothalamin were evaluated in vitro against human tumor cell lines, and most of them showed an inhibitory effect against HL-60 cancer cells. The derivatives 10-nitro-goniothalamin (2) and 10-amino-goniothalamin (4) gave selective inhibition concentration (IC50) of 1.10 and 1.14 μg/ml, respectively, against human stomach cancer SGC-7901 cells, while that of etoposide (vp-16) as the positive control was 6.07 μg/ml. Finally, the partition coefficients, logP (π values), of these derivative molecules, were evaluated by calculating the additive approximate organic fragment logP value.
通过化学修饰和半合成的方法,制备了 19 种天然化合物 goniothalamin(1)的新衍生物(2-20)。在体外评估了这些衍生物和香豆素对人类肿瘤细胞系的抗肿瘤活性,其中大多数对 HL-60 癌细胞有抑制作用。衍生物 10-硝基-goniothalamin(2)和 10-氨基-goniothalamin(4)对人胃癌 SGC-7901 细胞的选择性抑制浓度(IC50)分别为 1.10 和 1.14 μg/ml,而作为阳性对照的依托泊苷(vp-16)的选择性抑制浓度为 6.07 μg/ml。最后,通过计算相加的近似有机片段 logP 值,评估了这些衍生物分子的分配系数 logP(π 值)。
