Synthesis and neuropharmacological evaluation of R(−)-N-alkyl-11-hydroxynoraporphines and their esters
摘要:
We synthesized several N-substituted-11-hydroxynoraporphines and their esters of varying chain length, evaluated their binding affinity at dopamine (DA) receptor sites in rat caudate-putamen membranes, and quantified their effects on motor activity in normal adult male rats. The 11-hydroxyaporphines showed similar neuropharmacological properties to the corresponding 10,11-catecholaporphines. At moderate doses, their esters proved to have more prolonged behavioral actions and superior oral bioavailability. (C) 2004 Elsevier Ltd. All rights reserved.

The N-demethylation of 3-deoxymorphine (1) was investigated using methyl chloroformate and hydrazine. 3-Deoxynormorphine (2) was obtained in 70% yield, and 3-deoxydihydronormorphine (3) was also obtained as a side product. The mu, delta, and kappa receptor binding affinity of a series of N-substituted 3-deoxynormorphines 6 and 7 and N-substituted 3-deoxydihydronormorphines 8-11 was also determined.
