components necessary for broad spectrum cytotoxicity. The acrylic acid derivates (Z)-2-(3,4-dichlorophenyl)-3-(4-nitrophenyl)acrylic acid (8) and (Z)-2-(3,4-dichlorophenyl)-3-(4-methoxyphenyl)acrylic acid (9) were inactive; confirming the importance of the cyanide moiety. The most potent 2-phenylacrylonitriles synthesized were (Z)-2-(3,4-dichlorophenyl)-3-(1H-indol-3-yl)acrylonitrile (3) and (Z)-2-(3
我们先前曾报道发现一种简单的共轭氰基药效基团,该药基团导致了作为雌激素选择性抑制剂的(Z)-2-(3,4-二氯苯基)-3-(4-硝基苯基)丙烯腈(1)的开发。受体阳性(ER + ve)人乳腺癌细胞系MCF-7。通过对丙烯腈和芳族取代基的修饰进行的进一步研究突出了广谱细胞毒性所必需的关键结构组分。丙烯酸衍生物(Z)-2-(3,4-二氯苯基)-3-(4-硝基苯基)丙烯酸(8)和(Z)-2-(3,4-二氯苯基)-3-(4-甲氧基苯基)丙烯酸(9)处于非活动状态;证实了氰化物部分的重要性。合成的最有效的2-苯基丙烯腈是(Z)-2-(3,4-二氯苯基)-3-(1 H-吲哚-3-基)丙烯腈(3)和(Z)-2-(3,4-二氯苯基)-3-(1 H-吲哚-5-基)丙烯腈(20)的平均GI 50值分别为1.4和0.53μM。另外五个(Z)-2-(3,4-二氯苯基)-3-(吲哚基)丙烯腈的平均GI 50值也≤8
