Abstract:
In this work, a new series of 2-[4-(2-furoyl)-1-piperazinyl]-N-aryl/aralkyl acetamides has been synthesized
and evaluated for their antibacterial potential. The synthesis was initiated by the reaction of different aryl/aralkyl amines (1a-u) with 2-bromoacetylbromide (2) to obtain N-aryl/aralkyl-2-bromoacetamides (3a-u). Equimolar quantities of different N-aryl/aralkyl-2-bromoacetamides (3a-u) and 2-furoyl-1-piperazine (4) was allowed to react in acetonitrile and in the presence of K2CO3, to form 2-[4-(2-furoyl)-1-piperazinyl]-N- aryl/aralkyl acetamides (5a-u). The structural elucidation was done by EI-MS, IR and 1 H-NMR techniques of all the synthesized compounds. All of the synthesized molecules were active against various Gram positive and Gram negative bacterial strains. Among them 5o and 5c showed very excellent MIC values. The cytotoxicity of the molecules was also checked to find their utility as possible therapeutic agents, where 5c (0.51%) and 5g (1.32%) are found to be least toxic in the series.
