Synthesis, characterization and antiinflammatory-analgesic properties of 6-(alpha-amino-4-chlorobenzyl)thiazolo [3,2-b]-1,2,4-triazol-5-ols.
A series of 6-(alpha-amino-4-chlorobenzyl)-thiazolo[3,2-b]-1,2,4-triazol-5-ols (2a-j) were synthesized from 6-(4-chlorobenzylidene) thiazolo[3,2-b]-1,2,4-triazolo-5(6H)-one (2) by applying Michael addition reaction. All the compounds were characterized by their melting points, elementary analysis, IR and 1H-NMR spectra and screened for their anti-inflammatory and analgesic activities. Among the derivatives compound 2i bearing 4-(4-acetylphenyl)piperazine showed the highest and dose-dependent analgesic and anti-inflammatory activity without inducing any gastric lesion.
