Biologically active cannabidiol analogs comprising a compound of the formula

##STR00001##

wherein one of R.sub.1 or R.sub.2 or both is/are the residue of a moiety formed by the reaction of an amino group of the amino acid ester of R.sub.1 or R.sub.2 or both with a dicarboxylic acid or a dicarboxylic acid derivative and the other R.sub.1 or R.sub.2 (in the case of the mono) is the residue of a dicarboxylic acid or dicarboxylic acid derivative or Hydrogen (H), (i.e. underivatized), and salts thereof. These CBD analogs are be useful in pain management in oncology and other clinical settings in which neuropathy is presented. Furthermore, these CBD-analogs are useful in blocking the addictive properties of opiates.

Provided herein are compounds of formula I, compositions comprising the compounds and method of treating various diseases with the compounds and compositions.

Provided herein are compounds of formula I, compositions comprising the compounds and method of treating various diseases with the compounds and compositions.

The present invention relates to novel anthelmintic compounds of formula (I) below: ##STR00001##
wherein Y and Z are independently a bicyclic carbocyclic or a bicyclic heterocyclic group, or one of Y or Z is a bicyclic carbocyclic or a bicyclic heterocyclic group and the other of Y or Z is alkyl, alkenyl, alkynyl, cycloalkyl, phenyl, heterocyclyl or heteroaryl, and variables X.sub.1, X.sub.2, X.sub.3, X.sub.4, X.sub.5, X.sub.6, X.sub.7 and X.sub.8 are as defined herein. The invention also provides for veterinary compositions comprising the anthelmintic compounds of the invention, and their uses for the treatment and prevention of parasitic infections in animals.
