Biocompatibility and biological activity of C fullerene adduct with L-threonine (C(CHNO)).

The aim of this work is to synthesise and study the biocompatibility and biological activity of the C fullerene adduct with l-threonine (C-Thr). The obtained adduct was identified using a complex of physicochemical methods, namely, C NMR spectroscopy, IR spectroscopy, thermogravimetric analysis, electron spectroscopy, elemental analysis, and high-performance liquid chromatography. The study of biocompatibility and biological activity of the C-Thr adduct included the study of haemocompatibility (haemolysis, platelet aggregation, plasma coagulation haemostasis, binding to human serum albumin, esterase activity), antiradical activity, cytotoxicity, cell proliferation, and interaction with DNA (determination of the DNA binding constant and genotoxicity).
