List of phenyltropanes
Phenyltropanes are a family of chemical compounds originally derived from structural modification of cocaine. These compounds present many different avenues of research into therapeutic applications, particularly in addiction treatment. Uses vary depending on their construction and structure-activity relationship ranging from the treating of cocaine dependency to understanding the dopamine reward system in the human brain to treating Alzheimer's & Parkinson's diseases. (Since 2008 there have been continual additions to the list and enumerations of the plethora of types of chemicals that fall into the category of this substance profile.) Many of the compounds were first elucidated in published material by the Research Triangle Institute and are thus named with ""RTI"" serial-numbers. Similarly, a number of others are named for Sterling-Winthrop pharmaceuticals (""WIN"" serial-numbers) and Wake Forest University (""WF"" serial-numbers).
