ENZYMATYCZNE I CHEMICZNE MODYFIKACJE FOSFOLIPIDÓW

At the moment, phospholipids are among the most interesting molecules. The possibilities of chemical and enzymatic modifications, while maintaining their integrity and unique nature, also contribute to these compounds' great interest. This review paper concerns the preparation of new phospholipid conjugates containing fragments of biologically active compounds not found naturally in phospholipids, and phospholipids enriched with specific fatty acids with health- promoting properties (structured phospholipids). Chemical methods for the synthesis of phospholipids containing conjugated linolenic acid (CLA), dehydroepiandrosterone (DHEA) or selected non-steroidal anti-inflammatory drugs (NSAIDs) at the sn-1 and/or sn-2 position have been described. In addition, the evaluation of the antiproliferative activity of the obtained conjugates against selected cancer cell lines was also described. Enzymatic methods of modifying natural phospholipids leading to their enrichment with bioactive polyunsaturated fatty acids and conjugated acids have also been described.
