[Display omitted] •Complex in vitro biocompatibility study of C60-Hyp adduct was performed.•Computer simulation for C60-Hyp–water binary system was applied.•Sizes and ζ-potentials of C60-Hyp associates in aqueous solution were obtained. Amino acid adducts of light fullerenes have a potential of application in a variety of fields of biomedicine, that is reactive oxygen species scavenging activity, anticancer activity, viruses and bacteria inactivation etc. In this work, the water-soluble C60 fullerene derivative with l-hydroxyproline (C60(C5H9NO3)2, C60-Hyp) was studied. Extensive biomedical investigation of this compound, namely, antiradical activity in the reaction with stable diphenylpicrylhydrazyl radical, the binding to human serum albumin, photodynamic properties, cytotoxicity in glioblastoma A172 and lung carcinoma A549 cell lines, erythrocytes haemolysis, platelet aggregation, genotoxicity on human peripheral blood mononuclear cells was conducted. Moreover, the dynamic and structural characteristics of C60-Hyp–H2O binary system were obtained using molecular dynamic (MD) method, and size distribution along with ζ-potentials of C60-Hyp associates was measured.
