La molécula fue inicialmente usada para el tratamiento para el hipogonadismo, sin embargo, tiempo después su uso se expandió con el fin de obtener mayor masa muscular y un mejor rendimiento a nivel deportivo. Su metabolismo ha sido estudiado a través de diferentes modelos in vivo, con ratones y humanos e in vitro con fragmentos celulares del hígado, esto con el fin de establecer los metabolitos que indiquen su uso a corto y largo plazo que permitan su detección en las muestras de control al dopaje. Con este trabajo se busca estudiar el metabolismo de la metandienona a través de un modelo in vitro de biotransformación con el hongo Cunninghamella elegans, el cual ha sido utilizado con gran variedad de moléculas debido a que su sistema enzimático es similar al de los mamíferos. Con el desarrollo del modelo se proponen cuatro metabolitos monohidroxilados en las posiciones 6,7,14,15, esto se realizó a través de la técnica de cromatografía de gases acoplada a espectrometría de masas GC-MS/EI, se plantearon las posibles rutas de fragmentación y se compararon con los reportados para otros modelos de biotransformación.Methandienone is one of the most reported anabolics in the adverse analytical findings of doping control laboratories worldwide. The molecule was initially used for the treatment of hypogonadism, however, later its use expanded to obtain greater muscle mass and better performance at the sports level. Its metabolism has been studied through different in vivo models, with mice and humans and in vitro with liver cell fragments, this to establish the metabolites that indicate its use in the short and long term that allow its detection in the samples. doping control. This work seeks to study the metabolism of methandienone through an in vitro model of biotransformation with the fungus Cunninghamella elegans, which has been used with a great variety of molecules because its enzymatic system is like mammals. With the development of the model, four monohydroxylated metabolites were identified at positions 6,7,14,15, this was done through the gas chromatography technique coupled to mass spectrometry (GC-MS / EI), the possible routes of fragmentation and were compared with those reported for other biotransformation models.MaestríaMagíster en ToxicologíaComportamiento de variables toxicológicas y de salud relacionadas con el consumo de sustancias psicoactivas.77 páginasapplication/pdfspaUniversidad Nacional de ColombiaBogotá - Medicina - Maestría en ToxicologíaDepartamento de ToxicologíaFacultad de MedicinaBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá610 - Medicina y saludDoping en los DeportesDoping in SportsmetandienonaBiotransformaciónmetabolismoesteroides anabolizantesMetabolismMethandienoneCunninghamella elegansAnabolic steroidsBiotransformationEstudio del metabolismo de la metandienona a través de un modelo in vitro de incubación con el hongo Cunninghamella elegansMethandienone metabolism study through an in vitro incubation model with the fungus Cunninghamella elegansTrabajo de grado - Maestríainfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/acceptedVersionTexthttp://purl.org/redcol/resource_type/TM1.
