RESUMO

Marijuana (Cannabis sativa) is a widely used plant and its various applications have important benefits. The plant Cannabis sativa has been used by man for centuries for eating, medicinal practices and religious rituals. In human subjects, its effects include analgesia, alterations in perceptions, cognition, memory and psychomotor activity. The cannabinoid compounds have been used in the cancer chemotherapy and AIDS, but the use of marijuana is a problem due to its unwanted effects (the psychotropic activity presented by the cannabinoid compounds). Due to the great interest in the effects caused by the compounds extracted from the Cannabis, several studies have been carried out with the aim to better understand the relationship between the chemical structure and the biological activity of cannabinoid compounds, as well as their interaction with the cannabinoid receptors (CB1 and CB2). Both are seven-transmembrane (TM) receptors that belong to the rhodopsin-like family Class A of G protein coupled receptors (GPCRs). This work represents a study of molecular modeling of the CB1 receptor based upon the published bovine rhodopsin structure, once the most of the therapeutic effects of cannabinoids compounds have been shown to be mediated through the CB1 cannabinoid receptor. This work also provides an investigation of the CB1 receptor-ligand interaction and a study of the CB1 receptor activation. A docking study was also performed in order to understand the main interactions that occur between ∆9 -THC, the principal psychoactive molecule present in cannabis, and its receptor CB1.
