Structure and biological perspectives of Cu(II)–indomethacin complexes
摘要:
The copper(II) complexes with the non-steroidal anti-inflammatory drug indomethacin (Hindo) in the presence of the nitrogen-donor heterocyclic ligands 2,2'-bipyridine (bipy), 1,10-phenanthroline (phen) or 2,2'-bipyridylamine (bipyam) have been synthesized and characterized. The crystal structures of [Cu(indo)(2)(bipy)]center dot 1.5MeOH center dot 0.5H(2)O and [Cu(indo)(2)(Phen)] center dot 1.85MeOH center dot 0.15H(2)O have been determined by X-ray crystallography. All compounds have been tested for their antioxidant and free radical scavenging activity as well as for their in vitro inhibitory activity against soybean lipoxygenase showing significant activity with the previously reported complex [Cu-2(indo)(4)(H2O)(2)] being the most active. The complexes exhibit good binding affinity to human or bovine serum albumin protein with high binding constant values. UV study of the interaction of the complexes with calf-thymus (CT) DNA has shown that the complexes can bind to CT DNA with [Cu(indo)2(bipyam)] showing the highest binding constant to CT DNA (K-b = 1.56(+/- 0.19) x 10(6) M-1). The complexes can bind to CT DNA via intercalation as concluded by cyclic voltammetry, DNA viscosity measurements and competitive studies with ethidium bromide (EB) which revealed the ability of the complexes to displace the DNA-bound EB.

Veterinary anti-inflammatory Cu(II) complexes of indomethacin (1-(4-chlorobenzoyl)-5-methoxy-2-methyl-1H-indole-3-acetic acid = IndoH), of the general formula [Cu(2)(Indo)(4)L(2)] (L = N,N-dimethylformamide (DMF), N,N-dimethylacetamide (DMA), N-methylpyrrolidone (NMP), and water), were studied by zero-field and X-band EPR spectroscopies, electronic spectroscopy, magnetic measurements, and X-ray powder
