title: Synthesis of some thiazolo[3,2-b]-1,2,4-triazole-5(6H)-ones and their novel Michael addition products with anti-inflammatory activities.
abstract: In this study, 21 new compounds having 2-methyl-6-benzylidenethiazolo[3,2-b]-1,2,4-triazol-5(6H)-one (2-4) and 2-methyl-6-(alpha-aminobenzyl)thiazolo[3,2-b]-1,2,4-triazole-5-ol (2a-4g) structures were synthesized. The structures of the compounds were proved by spectral and elemental analysis. All of the compounds synthesized were tested for their anti-inflammatory actively and ulcerogenic potential in mice at 10, 20 and 40 mg/kg dose levels. Compound 4b showed higher anti-inflammatory activity than the analogue derivatives and indometacin (CAS 53-86-1), used as a reference drug, at 10 mg/kg dose level. Generally, the compounds were found to be more reliable than indometacin since they did not cause any reaction in the stomach.
