region of the olefinic double bond by introduction of the characteristic alkenyl side chain of ascofuranone (compounds 10a-f and 11a-f) markedly decreased the cytostatic activity as compared to geiparvarin itself, but this effect does not seem to be correlated to the presence of the furanone moiety linked to the alkenyl chain or to the ability to afford Michael type adducts. Replacement of the coumarin
继续研究负责细胞抑制活性的geiparvarin(1)的结构特征,一系列4,5-二氢-3(2H)-呋喃酮10a-f和3(2H)-呋喃酮11a-f以及设计并合成了2“,3”-二氢geiparvarin(14)。评估了它们对小鼠(L1210,FM3A)和人类(Raji,Molt / 4F和MT4)肿瘤细胞增殖的抑制作用。通过引入异黄酮的特征性烯基侧链(化合物10a-f和11a-f)在烯属双键区域进行的修饰与吉巴伐林本身相比明显降低了细胞抑制活性,但这种作用似乎与呋喃酮部分与烯基链连接或具有提供迈克尔型加合物的能力。用其他芳环取代香豆素部分并没有改变细胞抑制活性。2“,3”-二氢geiparvarin(14)的基本无活性表明3(2H)-呋喃酮环系统在细胞抑制活性中的重要性;因此,该部分可被视为抗肿瘤活性的决定性药效团,而侧链则起着相当的调节作用。
