Curator's Comment: Description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/19332567

Preladenant (SCH-420814) is an adenosine A(2A) receptor antagonist with a high affinity and very high selectivity for adenosine A(2A) receptors, which is being developed by Merck & Co Inc (following its acquisition of Schering-Plough Corp) for the potential treatment of Parkinson's disease. Preladenant is a potent competitive antagonist of the human A2Areceptor (Ki = 1.1 nM) and has >1000-fold selectivity over all other adenosine receptors, making this compound the most selective A2A receptor antagonist reported to date. Preladenant was being researched as a potential treatment for Parkinson's disease. Positive results were reported in Phase II clinical trials in humans, but it did not prove itself to be more effective than a placebo during Phase III trials, and so was discontinued in May 2013.
