exhibited the antitubercularactivity with the MIC of 25 μg/mL and anti-HIV activity with the MIC of 35.4 μg/mL against HIV1 and HIV2 and offers potential lead for further optimization and development to new antitubercular and anti-HIV agents. The results from this study confirm that the synthesized and biologically evaluated quinazolines showed promising antimicrobial, antitubercular and anti-HIV activities

synthesized compounds were screened for their antitubercular, anti-HIV and antibacterial activity against different gram positive and gram negative strains by agar dilution method. Among the test compounds, 2-(3-(4-chlorophenyl)-4-oxo-3,4-dihydroquinazolin-2-yl)-2,3-dihydrophthalazine-1,4-dione (QCT7) shown most potent antibacterial activity against E. coli , and S. aureus with the MIC of 3 µg/mL. The compound

日期:——
A series of (2-alkylthiothiazolin-5-yl)methyl dodecanoates was synthesized from various alkyl N-allylcarbamodithioates and dilauroyl peroxide via a tandem radical hydrogen-abstraction–cyclization–substitution/combination reaction with a 5-exo-trig radical cyclization as a key step. The current route is the first, convenient, and efficient synthesis of (2-alkylthiothiazolin-5-yl)methanol derivatives.
