Inhibitors of a critical brain enzyme, N-acetyltransferase (ANAT), and methods of discovering, making and using the same for the treatment of disease are disclosed.

Lysosomally accumulated substances that release a nitroxy group, or a short chain fatty acid or a product of anaerobic metabolism or a thiol or a sulfide often from an ester or similar labile linkage have anti-inflammatory, anti-cancer and anti-bacterial activity. They are useful in treating infectious, inflammatory and malignant disease and are immune stimulatory, promote zinc uptake, disable endosomal reactions and synergise anti-viral action of protease inhibitors. The compounds are useful for the treatment of bacterial, viral and mixed pneumonias.

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.
