Abstract

The neutral mononuclear copper complexes with the quinolone antibacterial drug ciprofloxacin and bipyridine derivatives have been synthesized and characterized. Complexes were screened for their antibacterial activity against three Gram((-)) and two Gram((+)) bacteria, and study suggests inhibition of gyrase activity by metal complexes as the possible mechanism. The nucleolytic activity of adducts was carried out on double stranded pUC19 DNA using gel electrophoresis in the presence of radical scavenging agents that suggest hydrolytic cleavage mechanism for plasmid DNA.
