Potential Protective Effects of Ruta Chalepensis L. Extracts Against Gentamicin-Induced Nephrotoxicity via Reduction on Apoptotic, DNA Damage and Oxidative Stress Markers in Mice.

In this study, the protective effects of Ruta chalepensis L. extracts on the extent of tissue damage in gentamicin-induced nephrotoxicity have been investigated. Ruta chalepensis L. extracts were prepared by subcritical water and ultrasound-assisted organic solvent extraction methods. Protective activity of Ruta chalepensis L. extracts on Gentamicin-induced nephrotoxicity is investigated by apoptotic, DNA damage, oxidative stress markers and evaluating histopathological in kidney tissue of mice. Gentamicin significantly increased Caspase-3 and -8 activities, NO levels, serum creatinine and BUN, while 8-OHdG and MDA levels were significantly decreased with Ruta chalepensis L. extract treatment. In addition, Ruta chalepensis L. extracts treatment significantly increased CAT and SOD activities. Histopathological alterations in Gentamicin group were significantly diminished by application of Ruta chalepensis L. extracts. These results suggest that treatment with Ruta chalepensis L. extracts may ameliorate renal dysfunction and structural damage through the reduction of oxidative stress and apoptosis in the kidney.

Cytotoxic and apoptotic potential of some coumarin and 2-amino-3-carbonitrile selenophene derivatives in prostate cancer.

3-acetyl coumarin derivatives (1a-d) are formed as a result of condensation of salicylaldehyde derivatives and ethyl acetoacetate and were converted into coumarin-selenophene hybrid compounds (2a-d) in the basic medium by modified Gewald reaction in the presence of malononitrile and selenium. Products are characterized by nuclear magnetic resonance (NMR). The prepared compounds are screened for their anticancer activity against DU-145 cell line. In addition, selected target compounds are evaluated for apoptosis and oxidative stress on DU-145 (prostate carcinoma) cell lines.
