In Vitro Anticancer Evaluation of Some Synthesized 2H-Quinolinone and Halogenated 2H-Quinolinone Derivatives as Therapeutic Agents.

Abstract

Searching for new cytotoxic agents with apoptosis induction may represent a viable strategy for cancer treatment to overcome the increased resistance to available anticancer agents. The purpose of the current study was aimed at preparation and anticancer evaluation of two new series of 2H-quinolinone and halogenated 2H-quinolinone derivatives against two cancer cell lines. Two new series of 2H-quinolinone and halogenated 2H-quinolinone derivatives were prepared and screened for their cytotoxicity against breast MCF-7 and liver HepG-2 cancer cell lines as well as normal breast MCF-10a. The tested molecules revealed good cytotoxicity and selectivity toward cancer cell lines relative to normal cells. These compounds were analyzed by DNA flow cytometry on MCF-7 cells. They were found to cause G2/M phase arrest and induced apoptosis at the pre-G1 phase. In addition, increased caspase 3/7 activity and decreased osteopontin expression verified the apoptotic activity. The potent compounds discovered in this study can be a hit for the discovery of new cytotoxic agents and are worthy of further investigation.
