Resumen

Esta propuesta tiene por objeto el desarrollo de compositos a partir de cannabinoides (CBD) inmovilizados sobre carbones, como instrumento futuro para la sustitución de cultivos ilícitos y/o la apertura de nuevas líneas económicas en Colombia contribuyendo a modelos de paz. Para esto, se obtuvo carbón activo a partir de la pirolisis de semillas y se funcionalizó con grupos amina (CAN). Los materiales obtenidos se caracterizaron fisicoquímicamente. La carga de CBD se realizó sobre los carbones y se evaluó la liberación a condiciones fisiológicas simuladas, a pH 2.1 (gástrico) y pH 7.4 (intestinal). Los materiales desorbidos se pusieron en contacto con aflatoxinas durante 15 minutos a 37°C en medio intestinal para evaluar el efecto dual de los carbones. La molécula de CBD tuvo una mayor afinidad por los materiales CAN, lo cual se atribuye a interacciones π deslocalizados-catión. Las liberaciones de CBD fueron cercanas al 90% en el medio gástrico, y alcanzaron el 100% en intestino. La remoción de aflatoxinas (AFLAB1) con CAN fue del 100% a partir de concentraciones de 426 μg/L. Los carbones permitieron la liberación controlada de CBD y la remoción subsecuente de aflatoxinas convirtiéndose en alternativas de valor terapéutico, mientras contribuye a la sustitución de cultivos ilícitos.
