Triamino-substituted 1, 3, 5-triazine and pyrimidine derivatives were synthesized and tested for antimtuor activities using some human cancer cell lines and murine leukemia cell lines. All the compounds having benzimidazolyl and morpholino groups as substituents on the 1, 3, 5-traizine ring showed antitumor activity. Pyrimidine derivatives having the same groups as substituents also showed antitumor activity. Among them, the compounds having 1-benzimidazolyl, morpholino and cis-2, 3-dimethylmorpholino groups as substituents on the 1, 3, 5-triazine ring or pyrimidine ring exhibited the most potent antitumor activity, and these compounds exhibited no or very weak aromatase inhibitory activity. In contrast, the compounds having imidazolyl group instead of benzimidazolyl group as a substituent on the 1, 3, 5-triazine ring showed a potent aromatase inhibitory activity.
研究人员合成了三氨基取代的 1, 3, 5-三嗪和嘧啶衍生物,并利用一些人类癌症细胞系和小鼠白血病细胞系对其抗肿瘤活性进行了测试。所有在 1,3,5-三嗪环上具有苯并咪唑基和吗啉基取代基的化合物都显示出抗肿瘤活性。具有相同取代基团的嘧啶衍生物也具有抗肿瘤活性。其中,以 1,3,5-三嗪环或嘧啶环上的 1-苯并咪唑基、吗啉基和顺式-2,3-二甲基吗啉基为取代基的化合物表现出最强的抗肿瘤活性,这些化合物不表现出或表现出很弱的芳香化酶抑制活性。与此相反,在 1,3,5-三嗪环上以咪唑基取代苯并咪唑基的化合物具有很强的芳香化酶抑制活性。
