efficient synthesis of 3,4-methylenedioxy-5,4'-dimethoxy-3'-amino-Z-stilbene (1c) and hydrochloride (1d) is reported. The nitrostilbene intermediate 6a was obtained via a Wittig reaction using phosphonium salt 4 and 3-nitro-4-methoxybenzaldehyde 5. A one-step reduction using zinc in acetic acid produced the synthetic objective amine 1c. The coupling of this amine with various Fmoc amino acids, followed
据报道有效合成了3,4-亚甲二氧基-5,4'-二甲氧基-3'-氨基-Z-sti(1c)和盐酸盐(1d)。通过使用t盐4和3-硝基-4-甲氧基苯甲醛5的Wittig反应获得亚硝基二苯乙烯中间体6a。使用锌在乙酸中的一步还原产生合成的目标胺1c。将该胺与各种Fmoc氨基酸偶联,然后裂解α-胺保护基,产生了一系列新的癌细胞生长抑制酰胺。胺1c,盐酸盐1d,甘氨酸酰胺3b和酪氨酸酰胺3f对一组六只人类和一只动物(P388)的活性最高(GI50 = 10(-2)-10(-3)micro g / mL) )癌细胞系。胺1c及其盐酸盐1d通过在秋水仙碱位点结合来有效抑制微管蛋白聚合,而酰胺对纯化的微管蛋白几乎没有活性。但是,大多数酰胺会导致处理过的细胞的有丝分裂指数显着增加,表明微管蛋白是其细胞内靶标。
