| Popis: | The poor bioavailability and stability of curcumin limit its clinical application. A novel Zn(II)-curcumin complex was synthesized and its effects against cyclophosphamide (CP)-induced reproductive damage were compared with curcumin. Oral administration of Zn(II)-curcumin significantly prevented CP-induced elevation of malondialdehyde (MDA) level and reductions in superoxide dismutase (SOD) activity and glutathione (GSH) content in mouse testis. Zn(II)-curcumin significantly ameliorated CP-induced reductions in body and reproductive organs weights. Zn(II)-curcumin dose-dependently ameliorated CP-induced reproductive system impairments, by improving sperm parameters (sperm count, viability, motility) and reducing serum testosterone and histological alterations. Compared to curcumin at the same dose, Zn(II)-curcumin more effectively alleviated CP-induced reproductive injury, leading to a reduced severity of testicular pathologic changes, lower MDA level, elevated SOD activity and GSH content, and increased sperm parameters and serum testosterone. These results suggest Zn(II)-curcumin more effectively protects against CP-induced reproductive damage than curcumin alone due to a synergistic reduction in oxidative stress. |
