The review deals with the scientific activity of the Department of Biochemistry of Lipids of the Palladin Biochemistry Institute of the National Academy of Sciences of Ukraine. The estimation of the functional role of some major lipids and of the minor lipid components, namely, N-acylethanolamines (NAE), is the main problem of the scientific investigations of the Department. The role of some lipids in the pathogenesis of diseases accompanied by the oxidative stress was also studied. The Department was the first to find and identify NAE in neuroblastoma C1300 N18 cells. It was shown that NAE with long saturated acyl chains inhibited veratridine-activated fast sodium channels. NAE also activated uterine plasma membrane smooth muscle Ca2+, Mg(2+)-ATPase, and inhibited Fe(2+)-induced free radical oxidation in mitochondria. The results of these investigations served as a basis for development of pharmacological substances with membrane protective properties. It was shown that, at different diseases accompanied by the oxidative stress, a significant change in the lipid composition of cell membranes occurred. Sometimes these changes were adaptive in character, which favored the cell viability adaptation to pathological conditions. The new level of regulation of adaptive reactions can be accompanied by the development of additive injuries of cell viability, which may be caused by the altered level of biologically active cell lipid components. Based on the results of these investigations, the preparation intended for treatment of male infertility was developed. The pharmacological substances intended for treatment of morphine abuse and acute ischemia of myocardium were created.

Adenylate kinase is a small, usually monomeric, enzyme found in every living thing due to its crucial role in energetic metabolism. This paper outlines the most relevant data about adenylate kinases isoforms, and the connection between dysregulation or mutation of human adenylate kinase and medical conditions. The following datadases were consulted: National Centre for Biotechnology Information, Protein Data Bank, and Mouse Genomic Informatics. The SmartBLAST tool, EMBOSS Needle Program, and Clustal Omega Program were used to analyze the best protein match, and to perform pairwise sequence alignment and multiple sequence alignment. Human adenylate kinase genes are located on different chromosomes, six of them being on the chromosomes 1 and 9. The adenylate kinases' intracellular localization and organ distribution explain their dysregulation in many diseases. The cytosolic isoenzyme 1 and the mitochondrial isoenzyme 2 are the main adenylate kinases that are integrated in the vast network of inflammatory modulators. The cytosolic isoenzyme 5 is correlated with limbic encephalitis and Leu673Pro mutation of the isoenzyme 7 leads to primary male infertility due to impairment of the ciliary function. The impairment of the mitochondrial isoenzymes 2 and 4 is demonstrated in neuroblastoma or glioma. The adenylate kinases are disease modifier that can assess the risk of diseases where oxidative stress plays a crucial role in pathogenesis like metabolic syndrome or neurodegenerative diseases. Because adenylate kinases has ATP as substrate, they are integrated in the global network of energetic process of any organism therefore are valid target for new pharmaceutical compounds.
