The 5,6- (5a) and 6,7-dihydroxy-3,4-dihydrospiro[naphthalen-1 (2H)-3'-piperidine] (6a) and their N-isopropyl derivatives (5b and 6b), DDSNPs, were synthesized. These compounds can be viewed as the result of the combination of the structure of the 3-(3,4-dihydroxyphenyl)-piperidine 2a or 2b, with the structure of the corresponding 1-(aminomethyl)-5,6-dihydroxy-(3a or 3b) or 1-(aminomethyl)-6,7-dihydroxy-1,2,3,4-tetrahydronaphthalene (4a or 4b), 1-AMDTNs. The new compounds (5a, b and 6a, b) were assayed for their alpha and beta adrenergic properties by means of binding experiments and functional tests and the results were compared with those obtained for catecholamines 1a, b and the previously described 3-(3,4-dihydroxyphenyl)piperidine (3-DPP; 2) and 1-AMDTNs (3, 4). Comparison of the affinity and activity data of novel derivatives with those of reference compounds 2, 3 and 4 shows a general low ability of DDSNPs 5 and 6 to interact with both alpha and beta- adrenoceptors.

Adrenergic Receptors: Trafficking

Adrenergic receptor trafficking is an active physiological process where adrenergic receptors are relocated from one region of the cell to another or from one type of cell to another. Discover the latest research on adrenergic receptor trafficking here.
