摘要： 以齐墩果酸、熊果酸和甘草次酸为原料,在碱性条件下,与二溴烷烃反应生成溴代烷烃酯;继而与对羟基苯甲腈发生亲核取代反应,共合成得到6个齐墩果酸/熊果酸/甘草次酸-对羟基苯甲腈缀合物,并采用MTT法测试其抗肿瘤活性。结果显示:[(4-氰基苯氧基)-正己基]-甘草次酸酯和[(4-氰基苯氧基)-正辛基]-甘草次酸酯对慢性髓系白血病细胞系K562有一定的抗增殖作用,其中[(4-氰基苯氧基)-正己基]-甘草次酸酯对人肝肿瘤细胞系Bel-7402也有中等抗增殖作用,其余化合物对所测细胞都没有抗增殖活性。[(4-氰基苯氧基)-正己基]-甘草次酸酯对测试细胞的抗增殖活性与阳性对照药5-FU相当,对正常肝细胞损伤较少,具有进一步研究的潜在价值。

Abstract: Oleanolic acid, ursolic acid and glycyrrhetinic acid were esterified with corresponding α,ω-dibromoalkane in the presence of potassium carbonate to prepare intermediates. Then, the intermediates were treated with p-hydroxybenzonitrile under potassium carbonate by means of a nucleophilic substitution reaction to generate six oleanolic acid/ursolic acid/glycyrrhetinic acid-p-hydroxybenzonitrile derivatives. Anti-tumor activity was tested by the MTT assay. The results showed that glycyrrhetinic acid-p-hydroxybenzonitrile conjugates [n-(4-cyanophenoxy)-hexyl]-3β-hydroxy-11-oxo-olean-12-en-29-oate and [n-(4-cyanophenoxy)-octyl]-3β-hydroxy-11-oxo-olean-12-en-29-oate had certain anti-proliferative effect on chronic myeloid leukemia cell line K562. Moreover, [n-(4-cyanophenoxy)-hexyl]-3β-hydroxy-11-oxo-olean-12-en-29-oate also had moderate anti-proliferative effect on human liver tumor cell line Bel-7402. Other compounds had no antiproliferative activity on the tested cell lines. [n-(4-Cyanophenoxy)-hexyl]-3β-hydroxy-11-oxo-olean-12-en-29-oate, which has less damage to normal liver cells, expressed almost the same level as the positive control drug 5-FU on the anti-proliferative activity of the tested cells. This indicated that [n-(4-cyanophenoxy)-hexyl]-3β-hydroxy-11-oxo-olean-12-en-29-oateand had the potential value for further research in anti-tumor field.

Key words: oleanolic acid, ursolic acid, glycyrrhetinic acid, p-hydroxybenzonitrile, antitumor activity
