Показано, что модифицированные молекулы BODIPY, а также производное дегидроэпиандростерона с диазириновой группой способны связываться в активном центре стероид-гидроксилаз человека с аффинностью, сравнимой с соответствующими величинами, рассчитанными для природных субстратов этих ферментов. При этом геометрия комплекса «фермент-лиганд» для модифицированного стероида в активном центре также соответствует геометрии комплексов CYP7 со своими природными лигандами, что указывает на возможность образования гидроксилированных продуктов реакции - меченых аналогов биометаболитов. Показано, что наличие одновременно диазириновой и 7-нитробензофуразановой групп значительно снижает сродство лиганда к активному центру CYP7A1 и, в особенности, CYP7B1. Идентифицированы аминокислотные остатки, расположенные вблизи фотоактивируемых групп и способные образовывать с ними ковалентные аддукты. Полученные результаты представляют интерес для объяснения механизма взаимодействия соединений, содержащих фотоактивируемые сшивающие группы с рекомбинантными ферментами CYP7 человека in vitro, а также для идентификации продуктов ковалентной модификации аминокислотных остатков белка, образующихся при фотоактивации исследованных молекул.</p></abstract><trans-abstract xml:lang="en"><p>In silico analysis of “protein-ligand” complexes of human CYP7 enzymes with modified borondipyrrome-tene (BODIPY) and steroids, containing photo-activated crosslinking groups, wasperformed in order to identify structural peculiarities of their interaction. It was found that BODIPY molecules and DHEA derivative with diazirine group are able to bind tightly with human steroid-hydroxylases. Binding affinity is comparable with corresponding values for essential ligands of the enzymes. Binding mode of the modified steroid corresponds to the binding mode of essential CYP7 ligands, so formation of hydroxylated products is possible. It was found that presence of both diazirine and NBD groups in a molecule significantly increases affinity of the compound in case of CYP7A1 and, especially, CYP7B1. Amino acid residues, located in a close proximity with photo-activated groups were detected, that can form covalent adducts with them. The obtained results can shed light on the mechanism of interaction of the compounds with recombinant human CYP7 enzymes in vitro. The results can also be used for the identification of modified amino acids of the proteins that are formed under photoactivation of the compounds in vitro.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>цитохром P450</kwd><kwd>CYP7A1</kwd><kwd>CYP7B1</kwd><kwd>диазирин</kwd><kwd>фотоаффинное мечение</kwd><kwd>BODIPY</kwd><kwd>докинг</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cytochrome P450</kwd><kwd>CYP7A1</kwd><kwd>CYP7B1</kwd><kwd>diazirine</kwd><kwd>photoaffinity labeling</kwd><kwd>BODIPY</kwd><kwd>docking</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке БРФФИ (проект № Х19РМ-062).</funding-statement><funding-statement xml:lang="en">This work was supported by BRFFR (project no.
