AFLATOXIN TEMPLATES, POLYMERS WITH MOLECULAR PRINTS AND METHODS FOR PRODUCTION AND USE THEREOF Russian patent published in 2019 - IPC C07D311/16 C08F222/10 C08F226/06 C08J9/26 B01J20/26 

FIELD: chemistry.

SUBSTANCE: invention relates to a template composition for sequestration of one or more aflatoxins containing: (a) aflatoxin template having formula (I), where R₁ is selected from H; R₂ is selected from halogen, CH₂C(O)OR' and CH(C(O)OR')₂; where R 'is selected from H and C_1-6 alkyl; and R₃ is selected from C_1-6 alkoxy or where R₁ together with R₂ form C_4-7 cycloalkyl ring; (b) monomers which are capable of chemically bonding to each other; (c) a support, where the monomers are methacrylic acid, 2-vinylpyridine, 2-hydroxyethyl methacrylate or any combination thereof. Invention also relates to an intermediate of a polymer with molecular prints comprising a complex of a cross-linked polymer and an aflatoxin template of formula (I), wherein the aflatoxin template is removable from the polymer to form a cavity, the size and/or shape of which enables aflatoxin to bind thereto.

EFFECT: technical result is obtaining a new composition based on an aflatoxin template of formula (I), which can be used in processing and production of dietary products, therapeutic agents, food and beverages, as well as for quality control and inspection purposes.
