  New Generation Dopaminergic Agents. 1. Discovery of a Novel Scaffold Which Embraces the D₂ Agonist Pharmacophore. Structure−Activity Relationships of a Series of 2-(Aminomethyl)chromans

  摘要：

  A series of 2-(aminomethyl)chromans (2-AMCs) was synthesized and evaluated for their affinity and selectivity for both the high-and low-affinity agonist states (D-2(High) and D-2(Low), respectively) of the dopamine (DA) D-2 receptor. The 7-hydroxy-2-(aminomethyl)chroman moiety was observed to be the primary D-2 agonist pharmacophore. The 2-methylchroman moiety was discovered to be an entirely novel scaffold which could be used to access the D-2 agonist pharmacophore. Attaching various simple alkyl and arylalkyl side chains to the 7-hydroxy 2-AMC nucleus had significant effects on selectivity for the D-2(High) receptor vs the 5HT(1A) and alpha(1) receptors. A novel DA partial agonist, (R)-(-)-2-(benzylamino)methyl)chroman-7-ol [R-(-)-35c], was identified as having the highest affinity and best selectivity for the D-2(High) receptor vs the alpha(1) and 5HT(1A) receptors. Several regions of the 2-AMC nucleus were modified and recognized as potential sites to modulate the level of intrinsic activity. The global minimum conformer of the 7-hydroxy-2-AMC moiety was identified as fulfilling the McDermed model D-2 agonist pharmacophoric criteria and was proposed as the D-2 receptor-bound conformation. Structure-activity relationships gained from these studies have aided in the synthesis of D-2 partial agonists of varying intrinsic activity levels. These agents should be of therapeutic value in treating disorders resulting from hypo-and hyperdopaminergic activity, without the side effects associated with complete D-2 agonism or antagonism.

  We designed, prepared and tested a set of structural analogs 1-4 as new hybrid compounds by incorporating, through a common alkyl chain of variable length, the pharmacophoric elements of N-n-allcyl nicotinium salts (non-alpha 7 nicotinic acetylcholine receptors antagonists) and of 7-hydroxy-2-(aminomethyl)chromanes (dopaminergic D-2 receptor agonists). The target compounds, which were assayed in binding experiments and electrophysiological, functional and Erk1/2 activation tests, essentially combined the pharmacological profiles of their individual receptor ligands. Among the studied derivatives, hybrid 2, one of the shortest homologs, in addition to the antagonist nicotinic profile similar to the other three congeners, behaved as a high affinity ligand at the investigated heteromeric nAChRs and as a low efficacy agonist at D(2)Rs. These bifunctional derivatives represent novel pharmacological tools in the study of nicotine addiction. (C) 2015 Elsevier Masson SAS. All rights reserved.
