Synthesis and structure of the Salen-Mn compound / 中国康复理论与实践

ABSTRACT

@#ObjectiveTo synthesize metal complex that exhibits superoxide dismutase (SOD)-like activity and determine its structure.MethodsThis chemical compound was synthesized by means of reflux in laboratory.Its structure was examined by infrared spectra (IR),nuclear magnetic resonance hydrogen spectra(H-NMR) and mass spectra (MS).The activity of the SOD was determine by xanthine oxidase (XOD).ResultsThe IR indicted that this complex showed a typical absorption band of -OH,C=N and benzene. The H-NMR reveals the existence of metal ion manganese (Mn3+ ,paramagnetic). The molecular weight was 365, which was obtained by EI-MS analysis. And this complex showed SOD-like activity.ConclusionA metal complex with low molecular weight and SOD-like activity has been synthesized.
