Brasofensine (NS-2214, BMS-204756) is a phenyltropane that had been under development by Bristol-Myers Squibb for the treatment of Parkinson's and Alzheimer's diseases. In animal models of Parkinson's disease, brasofensine was effective in stimulating LMA and reversing akinesia. Phase II trials in humans were conducted in 1996 and brasofensine was shown to be both effective and well tolerated at a dose of 4 mg; however, development was stopped after in vivo cis-anti isomerization of the 2α-methyloxime group was reported.
