| [View PDF] | DOI: DOI not available | Abstract:Twelve phenylglyoxylic acid derivatives were synthesized, characterized and investigated for their antibacterial activity against nine Gram-positive and four Gram-negative bacterial isolates. Some of the synthesized compounds exhibited broad spectrum activity against the bacterial strains, with 2-[2-(acetylamino)phenyl]-N-(2-chlorophenyl)-2-oxoacetamide (9) being the most active, having MIC values of 7.8-1000 µg/ml and MBC of 31.3-2000 µg/ ml. Seven of the phenylglyoxylic acid derivatives were investigated for their anti-inflammatory activity (acute inflammation, pulmonary oedema and leucocyte counts) in mice. The reduction in oedema formation was between 22-67 % for all the synthesized compounds. The compounds showed significant anti-inflammatory activity with 2-[2-(acetylamino)phenyl]-N-(2,4-dichlorophenyl)-2-oxoacetamide (13) being the most active, while others appear variously dose-dependent. | Keywords: Phenylglyoxylic acid amides, Synthesis, Antibacterial activity, Anti-inflammatory activity. |
