The nucleophilic addition reaction of N-tosyl-4-oxo-4, 5, 6, 7-tetrahydroindole (12) with the lithium salt of 1-methoxyindole (5), followed by dehydration with 2, 3-dichloro-5, 6-dicyano-1, 4-benzoquinone (DDQ) gave the derivative of 2, 4'-bi-1H-indole (9) which provides a new concise synthetic method of an indole pigment of the slime mould, arcyriacyanin A. The compound was first demonstrated here to have unique inhibitory activity to a panel of human cancer cell lines and to inhibit protein kinase C and protein tyrosine kinase.
N-托斯基基-4-氧-4, 5, 6, 7-四氢吲哚(12)与1-甲氧基吲哚(5)的锂盐发生亲核加成反应,随后与2, 3-二氯-5, 6-二氰基-1, 4-苯醌(DDQ)脱水反应,得到了2, 4'-双1H-吲哚(9)的衍生物,这提供了一种合成粘液霉吲哚色素阿尔基瑞安A的新型简洁方法。该化合物首次在这里被证明具有对一系列人类癌细胞系的独特抑制活性,并能够抑制蛋白激酶C和蛋白酪氨酸激酶。
