Organosulfur compounds and compositions are disclosed which can be administered in order to provide protection from the formation of aldehyde-protein adducts, protein aggregates, 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, traumatic brain injury, stroke and cerebral ischemia.

The present invention provides a method of forming paracyclyophane containing disulfide functional group. The paracyclophane is prepared by adding 3,3-dithiodipropionic acid (DPDPA) and N-ethyl-N-(3-(dimethylamino)propyl)carbodiimide (EDC) into 4-aminomethyl [2,2] paracyclophane. The present invention further provides a chemical film and a method of forming the same. The chemical film contains poly-p-xylylene with disulfide functional group and is formed on a substrate by a chemical vapor deposition process.
