But all of them have varying degrees of ulcerogenic properties. To overcome these limitations search is ongoing throughout the World to find new effective and safe anti-inflammatory agent. Therefore, of course, the synthesis of thiazolidines annelated with the pyridine cycle and the study of their anti-inflammatory properties is an interesting and relevant area. The objective of the present work was to synthesize a series of novel thiazolo[4,5-b]pyridine-2-ones by the structural modification of the (5,7-dimethyl-2-oxo-thiazolo[4,5-b]pyridine-3-yl)-acetic acid hydrazide for further pharmacological screening in vivo as anti-inflammatory activities. The objects of the study were thiazolo[4,5-b]pyridines, obtained by the structural modification of the (5,7-dimethyl-2-oxo-thiazolo[4,5-b]pyridine-3-yl)-acetic acid hydrazide. Anti-inflammatory activity was evaluated using carrageenan induced rat paw edema method in rats In vivo studies were carried out for anti-inflammatory activity employing the carrageenan-induced rat paw edema method. Anti-inflammatory activity was defined by measuring the paw edema volume 4 h after the carrageenan injection.The NSAID drug Ibuprofen in effective therapeutic doses were tested inparallel as an activity references. Inhibition of the inflammatory response was expressed as a percentage of the paw volume reduction. Studies of anti-inflammatory activity showed that the synthesized compounds had pronounced diuretic properties, and some of them according to activity indicators were approaching or exceeding comparative preparations. The results of the anti-inflammatory activity of the synthesized compounds derivatives (5,7-dimethyl-2-oxo-thiazolo[4,5-b]pyridine-3-yl)-acetic acid hydrazide show the potential for the search for anti-inflammatory agents among thiazolo[4,5-b]pyridine-2-ones.
