 Composite preparations based on heterocyclic amine-containing naphthoquinone derivatives and surfactant rhamnolipids were obtained. The intensity of the processes of lipid peroxidation (LPO), oxidative modification of proteins (OMB) and radical-absorbing activity against 1,1-diphenyl-2-picrylhydrazyl (DFPG) was studied. Compounds exhibiting high antioxidant activity against LPO and OMB processes were identified, namely: 2-[(6-(4-fluorophenyl-5-oxo-2,5-dihydro-1,2,4-triazin-3-yl) phenyl)amino]naphthalene-1,4-dione 1d and its composite preparation with rhamnolipid 1d + RL. It was found that all synthesized compounds show antioxidant activity in LPO processes.
