Marijuana (Cannabis sativa) has long been known to contain antibacterial cannabinoids, whose potential to address antibiotic resistance has not yet been investigated. All five major cannabinoids (cannabidiol (1b), cannabichromene (2), cannabigerol (3b), Delta(9)-tetrahydrocannabinol (4b), and cannabinol (5)) showed potent activity against a variety of methicillin-resistant Staphylococcus aureus (MRSA)strains Of Current clinical relevance. Activity was remarkably tolerant to the nature of the prenyl moiety, to its relative position compared to the n-pentyl moiety (abnormal cannabinoids), and to carboxylation of the resorcinyl moiety (pre-cannabinoids). Conversely, methylation and acetylation of the phenolic hydroxyls, esterification of the carboxylic group of pre-cannabinoids, and introduction of a second prenyl moiety were all detrimental for antibacterial activity. Taken together, these observations Suggest that the prenyl moiety of cannabinoids serves mainly as a modulator of lipid affinity for the olivetol core, a per se poorly active antibacterial pharmacophore, while their high potency definitely Suggests a specific, but yet elusive, mechanism of activity.

The present invention relates to novel cannabidiol quinone derivatives of formula (I) (I) wherein R is the carbon atom of a, linear or branched group, represented by: alkyl, aryl, alkenyl, alkynyl, acyl or alkoxycarbonyl groups; or wherein R is the nitrogen atom of a, linear or branched group represented by: alkylamine, arylamine, alkenylamineor alkynylamine groups. The invention also relates to the use of any of the compounds of formula (I)as medicamentsin therapy, particularly for treating diseasesand conditions responsive to PPARg modulationdue to their high PPARg agonistic effect lacking electrophilic (Nrf2 activation) and cytotoxic activities. This invention also provides pharmaceutical compositions comprising said compounds and method of treating diseases with said compounds.
