5-arylisatin derivatives were synthesized in 5-6 steps from readily available starting materials. Their structures were confirmed by 1H NMR and 13C NMR as well as LC/MS. The cytotoxicity of these novel isatins against human leukemia K562 cells were evaluated by MTT assay in vitro. SAR studies indicated that the N-substituted benzyl and C-5 substituted phenyl groups greatly enhance their cytotoxic activity
从易于获得的起始原料中,以5-6个步骤合成了许多5-arylisatin衍生物。它们的结构通过1 H NMR和13 C NMR以及LC / MS确认。在体外通过MTT分析评估了这些新颖的靛红对人白血病K562细胞的细胞毒性。SAR研究表明,N-取代的苄基和C-5取代的苯基基团大大增强了它们的细胞毒性活性,而保持在母体环上C-3上完整的羰基官能度是必需的。尤其是,N-(对甲氧基苄基)-5-(对甲氧基苯基)Isatin(化合物2m)对K562细胞系表现出最高的抗肿瘤活性(IC50 = 0.03μM)。此外,化合物2m的治疗可显着抑制肝癌HepG2细胞的增殖和迁移,这也可以减少人脐静脉内皮细胞(HUVEC)管的形成。总之,化合物2m在体外通过血管生成反应表现出非常良好的癌细胞增殖抑制作用,并且2m可能是有希望的用于癌症治疗的血管生成抑制剂。
