inhibitors. This work describes the synthesis of related furoindoles and their ability to synergize with suberoylanilide hydroxamic acid (SAHA) against neuroblastoma and breast cancer cells. The nucleophilic substitution of hydroxyindole methyl esters with α-haloketones yielded the corresponding arylether ketones, which were subsequently cyclized to tricyclic and tetracyclic furoindoles. The furoindoles showed
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。
