Pharmacological and spectral studies of synthetic biomimetic copper complexes derived from 3-hydroxyflavone derivatives as anti-inflammatory agents
Abstract Novel biomimetic ligands were synthesized by the condensation of 3-hydroxyflavone, 2-aminophenol(L1)/2-aminobenzoic acid (L2) and-aminothiazole (L3). Their Cu(II) complexes have also been synthesized and characterized on the basis of 1H...
