  Synthesis and dopamine agonist and antagonist effects of (R)-(-)- and (S)-(+)-11-hydroxy-N-n-propylnoraporphine

  摘要：

  The R-(-) and S-(+) enantiomers of 11-hydroxy-N-n-propylnoraporphine, (R)-3 and (S)-3, were synthesized in six steps from 1-(3-methoxy-2-nitrobenzyl)isoquinoline. Neuropharmacological evaluation of the R and S isomers (by affinity to dopamine receptor sites in rat brain tissues, induction of stereotyped behavior, and interaction with motor arousal induced by (R)-apomorphine in the rat) indicated that, similar to the 10,11-dihydroxy congener 2, both enantiomers can bind to dopamine receptors but that only (R)-3 activates them, whereas (S)-3 shows activity as a dopaminergic antagonist.

  (R)- and (S)-enantiomers of 11-hydroxy- and 10,11-dihydroxy-N-allylnoraporphine: synthesis and affinity for dopamine receptors in rat brain tissue

  摘要：

  The R-(-)- and S-(+)-enantiomers of 11-hydroxy-N-allyl (4), and 10,11-dihydroxy-N-allyl (3) congeners of 11-hydroxy-N-n-propylnoraporphine (11-OH-NPa, 2) or N-n-propylnorapomorphine (NPA, 1) were synthesized. Binding affinity of these compounds at dopamine (DA) receptor sites was evaluated with a membrane preparation of corpus striatum from rat brain. The R/S enantiomeric receptor affinity ratio was enhanced by allylic substitution of 3 and 4 and their R isomers had high DA receptor affinity similar to that of the N-n-propyl congeners. These N-allylaporphines are proposed as useful precursors to the preparation of their tritiated N-n-propyl enantiomers.

  A series of C11-substituted (R)-aporphines and C11-oxygenated (R)-noraporphines has been synthesized and evaluated for central serotonergic and dopaminergic effects in vitro and in vivo. The various C11-substituents were introduced using efficient nickel- and palladium-catalyzed reactions of the corresponding triflate (R)-11-[[(trifluoromethyl)sulfonyl]oxy] aporphine (6), Several compounds display high affinity to serotonin 5-HT1A receptors in spite of major differences in steric bulk and electronic properties of the various C11-substituents. A change of the N-methyl group of the nonselective 3 to H [23, (R)-11-hydroxynoraporphine] or propyl [2, (R)-11-hydroxy-N-propylnoraporphine] increases the selectivity for 5-HT1A receptors (100-fold) and dopamine D-2A receptors (3-fold), respectively. Compounds 3 and 23 have similar affinities to 5-HT1A receptors, whereas the propyl substituent of 2 not only enhances the selectivity for D-2A receptors but also increases the D-2A affinity. Modeling of ligand-receptor binding site interactions yielded an interaction site model for the 5-HT1A receptor that describes a gradual change in binding mode for C11-hydroxy, -methoxy-, and -phenyl-substituted derivatives. Hydrogen bonding is hereby gradually replaced by van der Waals interactions involving a relatively large lipophilic pocket. The derived D-2A receptor model can accommodate both the N-propyl substituent of 2 and the C11-ethyl substituent of 11 [(R)-11-ethylaporphine].
