J L Neumeyer et al.
Journal of medicinal chemistry, 26(4), 516-521 (1983-04-01)
The enantiomers [(S)-(+) and (R)-(-)] of N-n-propylnorapomorphine (NPA) were synthesized. (R)-NPA was obtained by the acid-catalyzed rearrangement of N-n-propylnormorphine. (R)-NPA also was converted to (RS)-N-n-propylnorapomorphine dimethyl ether by dehydrogenation of the 10,11-O,O'-dimethyl ether of (R)-NPA with 10% palladium on carbon
R F Cox et al.
The Journal of pharmacology and experimental therapeutics, 247(1), 355-362 (1988-10-01)
Prompted by conflicting reports of both agonist and antagonist properties of the S-(+)-enantiomer of the potent dopamine agonist R-(-)-N-n-propylnorapomorphine (NPA), we carried out extracellular, single unit recording studies to compare the effects of both enantiomers on substantia nigra and ventral
