Synthesis, DFT Studies, and Biological Applications of Some Novel Compounds Containing Lawsone by Using Halo-Reagents

A novel binary compounds as 3-(1,3-diphenyl-1H-pyrazol-4-yl)-2-phenyl-2H-benzo[f]indazole-4,9-dione (10) and fused 2-hydroxy-3-(4-hydroxy-7-methoxy-2-oxo-1,2-dihydroquinolin-3-yl)naphthalene-1,4-dione (7) naphtho[2,3-b]furan-3,4,9(2H)-trione (6) based on lawsone ‘that plays important precursor’ was synthesized by reaction with 1,3-diphenyl-1H-pyrazole-4-carbaldehyde halo-compounds, such 2-chloroacetyl chloride or 3-bromo-4-hydroxy-7-methoxyquinolin-2(1H)-one. Spectra elemental analysis of newly were investigated. The target molecules showed easy access to antioxidant (calorimetrical measurement) antitumor (Ehrlich ascites carcinoma [EAC] cells) activities. Geometrical isomers (enol, Keto conformers, syn, anti-conformers) achieved density functional theory (DFT) that conformed the spectral investigated compounds.Supplemental data for this article is available online at here.
