The present invention provides an amino acid composition, and a method for producing amino acids by means of energy irradiation, the method comprises contacting a nanostructure catalyst with at least one nitrogen-containing source, at least one hydrogen-containing source and at least one carbon-containing source, and irradiating the nanostructure catalyst, the nitrogen-containing source, the hydrogen-containing source and the carbon-containing source with energy, to produce the amino acids.

One aspect of the invention provides a composition of novel high penetration compositions (HPC) or a high penetration prodrug (HPP) for treatment of Parkinson's disease. The HPCs/HPPs are capable of being converted to parent active drugs or drug metabolites after crossing the biological barrier and thus can render treatments for the conditions that the parent drugs or metabolites can. Additionally, the HPPs are capable of reaching areas that parent drugs may not be able to access or to render a sufficient concentration at the target areas and therefore render novel treatments. The HPCs/HPPs can be administered to a subject through various administration routes, e.g., locally delivered to an action site of a condition with a high concentration or systematically administered to a biological subject and enter the general circulation with a faster rate.
