Ommochromes – screening and antioxidant organelles of the compound eye of invertebrates perform the function of light filtration, light absorption and antioxidant protection. In the present work, it was found for the first time that ommochromes exhibit antiglycation activity in vitro. Ommochromes were obtained from the eyes of three different insect families: Strationyidae, Sphingidae, and Acrididae. It was shown that all the studied ommochromes inhibited the reaction of formation of fluorescent products of serum albumin modification in the presence of high fructose concentrations (fructosylation). Ommochromes from the eyes of the black soldier fly (Hermetia illucens) were the most effective inhibitors of the fructosylation process. Ommochromes oxidized with hydrogen peroxide did not exhibit an inhibitory effect on the glycation process. The results obtained are of interest both for understanding the biological role of ommochromes in invertebrates, in particular for elucidating their effect on the oxidative modification of proteins of retinular and pigment cells of ommatidium, and for creating pharmacological preparations based on them for the treatment and prevention of pathologies associated with the development of metabolic syndrome.

Key words: ommochromes, insects, glycation, fructosylation
