Abstract

The naturally occurring aporphine alkaloid nantenine, has been shown to antagonize behavioral and physiological effects of MDMA in mice. We have synthesized (+/-)-nantenine via an oxidative cyclization reaction with PIFA and evaluated its binding profile against a panel of CNS targets. To begin to understand the importance of the chiral center of nantenine with regards to its capacity to antagonize the effects of MDMA in vivo, (R)- and (S)-nantenine were prepared and evaluated in a food-reinforced operant task in rats. Pretreatment with either nantenine enantiomer (0.3mg/kg IP) completely blocked the behavioral suppression induced upon administration of 3.0mg/kg MDMA. (+/-)-Nantenine displayed high affinity and selectivity for the alpha(1A) Adrenergic Receptor among several Other receptors suggesting that this alpha(1) subtype may be significantly involved in the anti-MDMA effects of the enantiomers.
