Design Synthesis and Preliminary Biological Evaluation of Benzylsulfone Coumarin Derivatives as Anti-Cancer Agents

摘要

In this work, a series of benzylsulfone coumarin derivatives – were synthesized and characterized. Kinase inhibitory activity assay indicated that most of the compounds showed considerable activity against PI3K. Anti-tumor activity studies of the active compounds were also carried out in vitro on the Hela, HepG2, H1299, HCT-116, and MCF-7 tumor cell lines by MTS assay. The structure–activity relationships (SARs) of these compounds were analyzed in detail. Compound exhibited the most potent activities against the mentioned cell lines with IC values ranging from 18.12 to 32.60 μM, followed by with IC values of 29.30–42.14 μM. Furthermore, and clearly retarded the migration of Hela cells in vitro. Next, an in silico molecular docking study was conducted to evaluate the binding models of and towards PI3Kα and PI3Kβ. Collectively, the above findings suggested that compounds and might be promising PI3K inhibitors deserving further investigation for cancer treatment.
