4-disubstitutued coumarin derivatives have been synthesized by the reaction of ethyl coumarin-3-carboxylate with pyrazole-3,5-dione and condensation of ethyl 7-hydroxycoumarin-3-carboxylate with 4,6-dibromo-3-amino phenol. Acylation with acetic anhydride and condensation of coumarin derivatives with 2-hydroxybenzaldehyde yielded the corresponding acetyl derivatives and 4-substituted pyrazole derivatives
通过香豆素-3-羧酸乙酯与吡唑-3,5-二酮的反应以及7-羟基香豆素-3-羧酸乙酯与4,6-二溴- 3-氨基苯酚。用乙酸酐酰化和香豆素衍生物与 2-羟基苯甲醛缩合得到相应的乙酰基衍生物和 4-取代的吡唑衍生物。通过光谱方法和元素分析阐明了合成化合物的结构。评价所有制备的衍生物对人乳腺癌细胞系(MCF-7)的细胞毒性。与标准市售药物星形孢菌素相比,化合物VI在MTT比色测定中显示出最小的IC 50值。
