Antimicrobial activity of 8-hydroxyquinoline and transition metal complexes
Heterocyclic compounds like 8-hydroxyquinoline (8HQ) and derivatives have been found in natural products and therapeutics. Herein 8HQ and metal complexes of 8HQ-5-substituted (X) uracils, X = I, N02(1-6) were investigated for their antimicrobial potency. The complexes 1 -6 exhibited growth inhibitio...
