The present invention relates to novel cannabigerol quinone derivatives of formula (I) wherein R is the carbon atom of a linear or branched group, represented by: alkyl, aryl, alkenyl, alkynyl, acyl, or alcoxycarbonil groups; or wherein R is the nitrogen atom of a linear or branched group, represented by: alkylamino, arylamino, alkenylamino or alkynylamino groups; or, alternatively, R represents a bond between 2 molecules of formula (I) forming a dimer. The invention also relates to the use of any of the compounds of formula (I) as medicaments in therapy, particularly for treating PPARg-related diseases due 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.
