UWA-101 (also known as α-cyclopropyl-MDMA) is a phenethylamine derivative invented at the University of Western Australia and researched as a potential treatment for Parkinson's disease. Its chemical structure is very similar to that of the illegal drug MDMA, the only difference being the replacement of the α-methyl group with an α-cyclopropyl group. MDMA has been found in animal studies and reported in unauthorised human self-experiments to be effective in the short-term relief of Parkinson's disease symptoms, especially when used alongside conventional treatment with L-DOPA. However the illegal status of MDMA and concerns about its potential for recreational use, neurotoxicity and potentially dangerous side effects mean that it is unlikely to be investigated for medical use in this appli
