Divalent salts of S-allylmercapto-N-acetylcysteine and related compositions are disclosed which can be administered in order to provide protection from the formation of aldehyde-protein adducts, protein carbonylation, protein aggregation, and the resulting neuroinflammation. Various neurodegenerative diseases which are suitable for treatment using these compositions include Alzheimer's disease, senile dementia, Parkinson's disease, multiple sclerosis, Lewy body disease, peripheral neuropathy, spinal cord injury, stroke and cerebral ischemia.

The present invention relates to a novel method for preparing bis(3-aminophenyl) disulphides of the general formula (I) and 3-aminothiols of the general formula (II), ##STR00001##
where X,Y have the meanings stated in the description,
which serve as intermediates for the preparation of phenyl sulphoxides having insecticidal, acaricidal and nematicidal activity.

A process includes forming a bio-derived crosslinking material from biorenewable aconitic acid. The process includes initiating a chemical reaction to form a bio-derived crosslinking material that includes multiple functional groups. The chemical reaction includes converting each carboxylic acid group of a biorenewable aconitic acid molecule to one of the multiple functional groups.
