Design, Synthesis, Characterisation, and Evaluation of Substituted Quinolin-2-one Derivatives as Possible Anti-lung Cancer Agents.

Background: According to 2022, the estimated number of cancer cases in India was found to be 1,461,427. Lung cancers are the leading cause of death among Indian males. Research on cancer has been conducted to develop better treatments that are safe and effective and could be used to diagnose cancer at an early stage.

Identification of Linomide Derivatives as Potential Anticancer Therapeutics using Molecular Docking Studies.

12 analogs bearing a structural similarity to Linomide, a bonafide anticancer agent were synthesized wherein cyclization of substituted dianilides rendered 4-hydroxyquinolin-2(1H)-ones that were subjected to a Mannich reaction to yield 4-hydroxy-3-(substituted-1-ylmethyl) quinolin-2(1H)-one analogs. Characterization was performed using IR, H nuclear magnetic resonance and C NMR spectral analysis. Subsequently, anticancer studies revealed that Compound 4b showed maximum cytotoxicity with IC values of 1.
