Synthesis and Spectral Characterization of Novel 2, 3-Disubstituted Quinazolin-4(3H) one Derivatives
New series of 2,3-disubstituted quinazolin-4(3H)one were synthesized via the reaction of the readily obtainable 2-thioxo-3-phenyl-quinazolin-4(3H)one 1 with ethyl chloroacetate followed by hydrazinolysis to afford the hydrazide 3 which allowed to react with different electrophilic reagents such as carbon disulphide, phenyl isothiocyanate, β-diketones, anhydrides, acrylonitrile, ethyl cinnamate,...
متن کاملSynthesis of Some New 2-substituted Quinazolin-4- One Derivatives and Their Biological Activties
A series of mannich bases (3a-3j) were synthesized by the reaction of 4-[2-methyl-4-oxo-4H-quinazolin-3-yl] benzoic acid (2) with formaldehyde and appropriate amines by conventional technique. The procedure afforded various quinazolinone derivatives with 75% yield. Structures were characterized by means of spectral data. All the synthesized compounds were subjected to biological evaluation for ...

Pathogenic infections and inflammation are very common ailments humans suffer. Upsurge of resistant pathogens has impeded the antimicrobial drug development process in recent years and the search of new antimicrobial agents is clearly evident from the literature. In line with these developments the synthesis of N-substituted aryl-2-({4-[(substituted aryl carbamoyl) methyl]-5-(pyridin-4-yl)-4H-1...
متن کاملSynthesis and Cytotoxic Evaluation of Novel 3-Substituted Derivatives of 2-Indolinone
The assessment of the degree or rate of cellular proliferation and cell viability is critical for the assessment of the effects of drugs on both normal and malignant cell populations. In the present study, a few novel 3-substituted derivatives of 2-indolinones were synthesized by condensation of substituted oxindole or isatin derivatives with appropriate aldehydes or primary aromatic amine...
