Effect of sweet grass extract against oxidative stress in rat liver and serum.

Ethanol metabolism is accompanied by generation of free radicals which can damage the cell components. However, sweet grass is a source of coumarin and its derivatives have emerged as a promising group of antioxidant compounds. The aim of this study has been to investigate the influence of sweet grass on oxidative stress formation in the liver and serum of rats intoxicated with ethanol.

Comparison of influence of carmustine and new proline analog of nitrosourea on antioxidant system in breast carcinoma cells (MCF-7).

The high toxicity and low selectivity of carmustine restrict its application in anticancer therapy. Therefore, proline analogs of nitrosourea have been synthesized to obtain compounds whose action on neoplastic cells is characterized by higher selectivity. The present studies have aimed at examining the influence of carmustine and a new proline analog of nitrosourea on the redox system of fibroblasts and breast cancer cells (MCF-7).

Proline analogue of nitrosourea as a new cytotoxic prodrug.

Carmustine is frequently used as anticancer drug. High toxicity and low selectivity reduces the application of this drug. Though, there is a necessity to find new compounds characterized by similar therapeutic effects but a higher selectivity and safety.
