Benz-imidazole fused benzopyran derivatives were prepared by the reaction of 2-(1H-Benzo[d]Imidazol-2-yl)-1phenyl-1H-Benzo[f]chromeno-3-amine with different substituted benzaldehydes. The resulting derivatives were subjected to physical and chemical characterization. The anti-bacterial potency of the synthesized compounds was tested against a set of Gram positive and negative bacteria. The compound 9-(2-methoxyphenyl)-16-phenyl-16H-benzo[4,5]imidazo[1,2-c]benzo[5,6]chromeno[3,2-e]pyrimidine exhibited most potent activity. Detailed toxicological studies and molecular modelling would be beneficial in developing new drugs.
