Biochemistry Group is organized following pattern of a mixed research unit, its staff work in co-operation with Department of Medical Biochemistry of the University of Latvia and Genomics and Bioinformatics Team of Institute of Biology of the University of Latvia. Premises of the Group are outside main building of the Institute, the team is housed downtown in the building of the Faculty of Biology of the University of Latvia. Main branches of the research: mechanism of action of the drugs developed in LIOS, role of nitric oxide in mechanism of action of pharmacological remedies, DNA-drug interactions. In recent years scientific interest of the team is focused on search for remedies for treatment of diabetes mellitus and its complications. Substances with both DNA-protecting and antioxidant activities are sought. Exploration of the direct interaction of ftorafur with DNA and mechanism of interaction of antimutagenic 1,4-dihydropyridine with DNA are our recent achievements.
