title: Synthesis and biological activity of acetamides, arylureas and 2-alkoxyphenyl-6-phenyl-1,3,4-oxa(thia)diazole-[3,2-a]-S- triazin-5,7-diones derived from 2-amino-5-alkoxyphenyl-1,3,4-oxa(thia)diazole.
abstract: The syntheses of some acetamides (II) and phenylureas (III) derived from 2-amino-5-alkoxyphenyl-1,3,4-oxa(thia)diazoles (I) and some 2-alkoxyphenyl-6-phenyl-1,3,4-oxa(thia)diazole-[3,2-a]-s- triazin-5,7-diones (IV) are described. Pharmacological tests showed antiinflammatory and analgesic activities of bicyclic derivatives. A probable influence of alkoxyphenyl substituents, present in three kinds of structures, was observed.
