Diabetes mellitus (DM) causes an imbalance in the oxidative status of the human body. Three novel Dapagliflozin (Dapg) Zn (II), Cr (III) and Se (IV) complexes were prepared and characterized by elemental analysis, IR, electronic spectra, magnetic susceptibility, scanning electron microscopy (SEM) and X-ray diffraction. The molar conductance values confirmed the non-electrolytic nature of the Dapg complexes. According to spectral data, Dapg acts as a bidentate ligand. The thermal analyses of the complexes were studied using the DSC technique. The surface morphology and particle sizes of the Dapg complexes were investigated using SEM and XRD. XRD confirmed the crystalline structure for the complexity. This study investigated the effect of novel metal complexes of Dapg with the metals Zn (II), Cr (III) and Se (IV) on oxidative injury and tissue damage in the hepatic tissue of streptozotocin (STZ)-induced diabetic male rats. DM was experimentally induced in male rats. The diabetic rats received Dapg, Dapg/Zn, Dapg/Cr and Dapg/Se orally for 30 successive days. Male rats exposed to STZ showed multi-histopathological alterations in their hepatic tissue, including inflammatory and structural changes. STZ elevated oxidative stress markers in the hepatic tissue and lowered the antioxidant defense enzymes. Supplementation of Dapg with Zn, Cr or Se novel complexes significantly prevented hepatic injury and suppressed the generation of reactive oxygen species. The Dapg/Zn complex was highly effective against Bacillus subtilis and Streptococcus penumonia, while Dapg/Cr was highly effective against Escherichia coli and Pseudomonas aeruginosa, and Dapg/Se was highly effective against Staphylococcus aureas. In conclusion, Dapg novel metal complexes with Zn, Cr or Se protect against oxidative injury and the pathophysiological and bacterial complications of DM and hepatic tissue injury. The Dapg novel metal complexes improved hepatic functions, reduced blood glucose levels and enhanced the levels of antioxidant defense enzymes in diabetic male rats.
