The metabolites were found to be camphecene glucuronide, camphecene sulfate and the corresponding iminoacid. A study of the dynamics of accumulation of camphecene and its metabolites in the liver, kidneys, lungs and brain of animals was performed. Maximum concentration of camphecene in blood and organs was reached after 1.5-2 h of its administration, and the maximal content of the agent in the organs investigated was observed in the kidneys. The content of the substance in the lungs was comparable to that in the liver. Also, camphecene was found in brain in high concentration, thus allowing assumption of its ability to penetrate the blood-brain barrier and to exert its antiviral properties in the organ. Camphecene glucuronide and iminoacid had concentration-time profiles similar to that of their precursor, their content being maximal in kidney and liver and 2-3 orders of magnitude higher than in lungs and brain. The content of camphecene sulfate was of similar level in all organs studied. The results obtained made it possible to develop recommendations for therapy with the use of camphecene.||URI:||https://cris.pasteurorg.ru/handle/123456789/31||ISSN:||0731-7085||DOI:||10.1016/j.jpba.2018.09.003|
