Synthesis and in vitro antimicrobial evaluation of pyrazolyl-quinazolin-4(3H)-ones.
A new series of 2-[2-(2,6-dichlorophenyl)amino]phenyl methyl -3-[(1-phenyl-5-substituted phenyl)-5-hydro-1H-pyrazol-3-yl-amino]-6,8-dibromoquinazolin-4(3H)-ones C1-13 have been synthesized by the reaction of 2-[2-(2,6-dichlorophenyl)amino]phenylmethyl-3-substituted phenyl chromene amido-6,8-dibromo-quinazolin-4(3H)-ones with phenylhydrazine in the presence of glacial acetic acid. The chalcones ...
متن کاملSynthesis and microbial studies of (4-oxo-thiazolidinyl) sulfonamides bearing quinazolin-4(3H)ones.
2-[(2,6-Dichlorophenyl)amino]phenylacetic acid (A) on reaction with thionyl chloride gave corresponding acid chloride (B). A series of (4-oxo-thiazolidinyl)sulfonamides of quinazolin-4(3H)ones (4a-l) were prepared from Schiff bases (3a-l) of 2-[2-(2,6-dichlorophenyl)amino]phenylmethyl-3-[(4-aminophenyl)sulfonamido-1-yl]quinazolin-4(3H)one (D) and substituted aromatic aldehyde. Newly synthesized...

متن کاملSynthesis, anti-microbial and molecular docking studies of quinazolin-4(3H)-one derivatives.
In this work, synthesis, antimicrobial activities and molecular docking studies of some new series of substituted quinazolinone 2a-h and 3a-d were described. Starting form 2-aminobenzamide derivatives 1, a new series of quinazolinone derivatives has been synthesized, in high yields, assisted by microwave and classical methods. Some of these substituted quinazolinones were tested for their antim...
