values against a panel of nine tumor cell lines, while not affecting nonmalignant fibroblasts. Indole 10 surpassed verubulin in seven tumor cell lines including colon, breast, ovarian, and germ cell cancer cell lines. In line with docking studies indicating that compound 10 may bind the colchicine binding site of tubulin more tightly (Ebind=−9.8 kcal mol−1) than verubulin (Ebind=−8.3 kcal mol−1), 10 suppressed
verubulin(Azixa®,MPC-6827,停产肿瘤血管破坏剂的两种类似物1),具有苯并-1,4-二恶烷-6-基(化合物5)和Ñ -methylindol -5-基(化合物10)制备了4-(甲基氨基)-2-甲基喹唑啉药效基团上的残基而不是对茴香基,发现其超过了前导化合物的抗肿瘤功效。它们具有抗增殖作用,对一组9种肿瘤细胞系具有个位数的纳摩尔IC 50值,而不会影响非恶性成纤维细胞。吲哚10在包括结肠癌,乳腺癌,卵巢癌和生殖细胞癌细胞系在内的七个肿瘤细胞系中,其蛋白的表达超过了Verubulin。与对接研究表明化合物线路10可以结合秋水仙碱更紧密地(微管蛋白结合的位点Ë绑定= -9.8千卡摩尔-1)比verubulin(Ë绑定= -8.3千卡摩尔-1),10抑制血管的形成纳摩尔浓度的受精卵的内皮细胞样管和破坏受精卵绒毛膜的血管。当应用于具有高度血管化的1411HP生殖细胞异种移植肿瘤的裸鼠时,化合物10
