Abstract The acid hydrazides (2) derived from ibuprofen and 4-methylthiophenyl acetic acids have been subjected to cyclization with carbon disulphide under basic conditions to yield 1,3,4-oxadiazol-2-thiones (3) which on aminomethylation with formaldehyde and secondary amines afforded a series of Mannich bases (4 and 5). Purity of the compounds has been confirmed by TLC. Structures of these compounds were established on the basis of elemental analyses and spectral studies. The newly synthesized compounds were evaluated for their anti-inflammatory, analgesic, ulcerogenic and antimicrobial activities. Copyright © 2010 Elsevier Masson SAS. All rights reserved.
