The natural product, chrysin (5,7-dihydroxy flavone), obtained from Oroxylum indicum, exhibits numerous biological activities including anticancer, anti-inflammatory, and antiallergic activities. Three series of chrysin analogues were prepared, in which chrysin and heterocyclic moieties are separated by 3-carbon, 4-carbon, and 6-carbon spacers. All the derivatives were screened for antibacterial activity against a panel of susceptible and resistant Gram-positive and Gram-negative organisms. It was observed that most of the derivatives displayed significant activity as compared to their parent compound (chrysin).
