Crystal Structure, Spectroscopic Characterization, DFT Calculations, and Antidiabetic Activity of Silver (I) Perchlorate Complex with Methyl 6-Quinolyl Ether

Abstract

The [Ag(C10H9NO)2]ClO4 complex was synthesized from the methyl 6-quinolyl ether (6-MQ) (C10H9NO) molecule, and this new structure was characterized by spectroscopic methods such as single-crystal X-ray diffraction, FT-IR, FT-Ra, 1H, and 13C NMR. In addition, these spectroscopic data were combined with DFT calculations. The X-ray diffraction analysis revealed that the Ag(I) complex crystallized in the monoclinic system with the P21/n. The asymmetric unit of the compound comprises one Ag(I) cation, two methoxyquinoline ligands with the same distance [2.134 & Aring;], and one ClO4- anion. Computational studies were performed by using the DFT approach on the present complex to get insight into the structural parameters, spectral characteristics, and electronic properties. The characterization results were found to be consistent with the proposed structure of the complex, and the DFT approach supported the experimental results. Also, the antidiabetic activity of the methyl 6-quinolyl ether silver perchlorate complex was investigated. It was determined that the complex had both alpha-amylase and alpha-glucosidase enzyme inhibition. Both enzyme inhibitory concentrations (IC50) of the complex with the standard drug acarbose were calculated. As a result, it was determined that this synthesized complex had antidiabetic properties.
