Preladenant (SCH 420814) was a drug that was developed by Schering-Plough which acted as a potent and selective antagonist at the adenosine A2A receptor. It was being researched as a potential treatment for Parkinson's disease.[1] Positive results were reported in Phase II clinical trials in humans,[2] but it did not prove itself to be more effective than a placebo during Phase III trials, and so was discontinued in May 2013.[3]

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
