Synthesis and Antiproliferatory Activities Evaluation of Multi-Substituted Isatin Derivatives.


ABSTRACT: A series of multi-substituted isatin derivatives were synthesized using the powerful Sandmeyer reaction. The structures of these derivatives were confirmed by 1H-NMR, 13C-NMR, and HR-MS. Inhibition of proliferation activities of these derivatives against human leukemia cells (K562), human hepatocellular carcinoma cells (HepG2) and human colon carcinoma cells (HT-29) were evaluated in vitro using the MTT assay. Among the series, compound 4l exhibited strong antiproliferatory activities against K562, HepG2 and HT-29 cells with IC50 values of 1.75, 3.20, and 4.17 ?M, respectively. The morphological, growth inhibitory and apoptosic effects of compound 4l in K562 cells, wound healing effect in HepG2 cells, and tube formating effect in matrix gel of HUVEC cells were evaluated consequently. All results indicated that compound 4l could be used as a potential antitumor agent in further investigations.
