Synthesis and in vitro cytotoxicity evaluation of isatin-pyrrole derivatives against HepG2 cell line

Abstract

This paper reports the synthesis and in vitro cytotoxicity evaluation of isatin-pyrrole derivatives 5-8, obtained from the appropriate isatins with pyrrole, with good yields and purity. The product structures were confirmed through spectroscopy methods. Furthermore, the MTT assay on the human liver cancer HepG2 cell lines revealed moderate activity in all compounds, which was highest in sample 6 (IC50 0.47 μM). The anticancer activity was affiliated with the presence of a nitro group at C-5 and N-methyl of the isatin scaffold.
