摘要:
                                Two series of isomeric thiazolo[3,2-b][1,2,4]triazole and thiazolo[2,3-c][1,2,4]triazole derivatives were prepared following multiple synthetic pathways.  The obtained compounds were submitted to preliminar pharmacological assays to evaluate their anti-inflammatory, analgesic and antipyretic activity.  Suggestions about structure-activity relationships between the two classes of isomers were delineated.  Moreover, some of the starting molecules, phenacylthio[1,2,4]triazoles were submitted to microbiological analysis to test their antibacterial and antimycotic activity.
