Triheterocycles with coumarin, benzofuran and furan rings are claimed by Khan and co-staff. The synthesized compounds had been screened from two bacterial and two fungal species with the standard cup plate system. Introduction of monochloro and dichloro substituents within the benzofuran ring Increased the antimicrobial potency against Pseudomonas chinchori, A. fumigatus, and P. wortmanni. Amongst the noted compounds, 53a–e exhibited appreciable inhibition of the microbial progress of many of the species at 50 μg mL−1 concentration.
