SIERRA-RIVERA, Crystel A. et al. In vitro and in silico biological evaluation of phthalimide derivatives as antiproliferative agents. TIP [online]. 2021, vol.24, e314.  Epub Nov 15, 2021. ISSN 1405-888X.  https://doi.org/10.22201/fesz.23958723e.2021.314.

Phthalimide is considered a scaffold for the development of new anticancer agents. In this work, the antiproliferative activity of forty-three phthalimide derivatives was evaluated against cervical (HeLa), liver (HepG2), breast (4T1) cancer cell lines, and a normal cell line of murine fibroblasts (3T3). Finally, a molecular docking analysis of phthalimide derivatives on the active site of the enzymes DNA methyltransferase 1 (DNMT1) and vascular endothelial growth factor receptor 2 (VEGR2) as potential drug targets was performed. The compounds, C16, E11, and E16 showed the best antiproliferative activity against the cell lines HeLa and 4T1. Only, the compound H16 decreased 32% cell proliferation against HepG2 cell line. The compounds H5, H16, E2, E16, and C1 did not affect the proliferation of the 3T3 cell line. The molecular docking analysis showed that phthalimide derivatives have a greater affinity for DNMT1 than S-adenosyl-l-homocysteine, a potent DNMT1 inhibitor. However, molecular docking results do not correlate with their antiproliferative effects, suggesting another potential mechanism of action for the active compounds.

Keywords : antiproliferative; DNA methyltransferase 1; molecular docking; phthalimide.
