FIELD: chemistry.SUBSTANCE: invention relates to a metal-salen complex derivative. The complex is represented as A-B-C, where A is the metal-salen complex, B is a bond zone, including at least one disulphide bond and C is a functional molecule, consisting of at least one of enzymes, antibodies, antigens, peptides, amino acids, oliginucleotides, proteins, nucleic acids and medication molecules. The bond zone (B) includes a molecule of a cross-linking agent to form a cross-linking between the said metal-salen complex (A) and the said functional molecule (C). The said metal-salen complex (A) and the said molecule of the cross-linking agent are bound together via at least one disulphide bond and the said molecule of the cross-linking agent and the said functional molecule (C) are bound together via at least one disulphide bond. The zone of the disulphide bond (B) results from the formation of a bond between a SH group, introduced as a substituent into the said metal-salen complex, and the SH group of the said functional molecule (C), or results from the formation of a bond between the SH group of the said metal-salen complex (A) or the said functional molecule (C) and the SH group of the cross-linking agent molecule. Also claimed is a method of obtaining the metal-salen complex derivative.EFFECT: invention makes it possible to obtain the derivative of a metal-salen complex, characterised by an excellent output and stability.3 cl, 2 exИзобретение относится к производному комплекса металл-сален.
