Solvent-Free Preparation and Antimicrobial Studies of Metal (Ii) Complexes Derived From Cloxacillin

Abstract

The authors use an environmental friendly, solvent-free method to prepare metal (II) complexes of cloxacillin and to determine the activity of the complexes. The complexes are more active against the bacteria isolates than the free cloxacillin. The spectral studies showed the cloxacillin (ligand) as monobasic bidentate material that form a complex with metal ion through the carbonyl of amide and carboxylate groups of carboxylic acid, microanalysis results prove that the ligand to metal ratio is 2:1. The researchers recommend the use of solvent-free drugs in the manufacture of metal (II) complexes of active pharmaceutical ingredients to avoid the excessive use of solvents that cause global problems.
