二氢吡喃吲哚结构以前被鉴定为有前途的支架,用于提高组蛋白脱乙酰酶抑制剂的抗癌活性。这项工作描述了相关呋喃吲哚的合成及其与辛二酰苯胺异羟肟酸 (SAHA) 协同对抗神经母细胞瘤和乳腺癌细胞的能力。羟基吲哚甲酯与α-卤代酮的亲核取代产生相应的芳醚酮,随后环化为三环和四环呋喃吲哚。呋喃吲哚显示出对乳腺癌细胞的有希望的个体细胞毒性效率,以及在特定情况下对癌细胞的良好 SAHA 增强。有趣的是,使用非环化中间体获得了最佳 IC 50值。

Pyrrolo[3,4-c]carbazoles bearing solubilising basic side chains at the 8-position retain potent Weel and Chk1 inhibitory properties in isolated enzyme assays, and evidence of G2/M checkpoint abrogation in several cellular assays. Co-crystal structure studies confirm that the primary binding to the Weel enzyme is as described previously, with the C-8 side chains residing in an area of bulk tolerance. (C) 2007 Elsevier Ltd.
