(3S,4S)-delta-6-tetrahydrocannabinol-7-oic acids and derivatives thereof, processors for their preparation and pharmaceutical compositions containing them

Abstract

The invention relates to novel compounds of formula (I) wherein R is a hydrogen atom or a C.sub.1 -C.sub.5 alkyl group and R.sup.2 is selected from the group consisting of: (a) a straight-chained or branched C.sub.5 -C.sub.12 alkyl radical; (b) a group --O--R.sup.4, wherein R.sup.4 is a straight-chained or branched C.sub.2 -C.sub.9 alkyl radical which may be substituted at the terminal carbon atom by a phenyl group; (c) a group --(CH.sub.2).sub.n --O--alkyl, wherein n is an integer of from 1 to 7 and the alkyl group contains from 1 to 5 carbon atoms, having the (3S,4S) configuration, essentially free of the (3R,4R) enantiomer. The invention also relates to process for the preparation of compounds of formula (I) as defined above. The invention further relates to pharmaceutical compositions which possess analgesic, anti-inflammatory, anti-emetic, anti-glaucoma, leukocytes antiadhesion or PAF activity, containing as active ingredient compounds of formula (I) as defined above.
