Synthesis and structure activity relationship of tetrahydroisoquinoline- based potentiators of GluN2C and GluN2D containing N-Methyl-D-aspartate receptors

We describe here the synthesis and evaluation of a series of tetrahydroisoquinolines that show subunit-selective potentiation of NMDA receptors containing the GluN2C or GluN2D subunits. Bischler-Napieralski conditions were employed in the key step for the

Synthesis of a small library of phenylalkylamide derivatives as melatoninergic ligands for human mt1 and MT2 receptors

Focused small libraries of melatonin receptor ligands from arylalkylamine derivatives were synthesised by combinatorial chemistry using the mix and split method in the solid phase. A library of 108 compounds was then synthesised from 12 arylalkyl amines and nine carboxylic acids. The compound mixtures were evaluated on chicken brain melatonin and recombinant human mt1 and MT2 receptors. Deconvolution of the most potent mixture demonstrated the superiority of 3-methoxy and 2,5-dimethoxy substitution on the phenyl ring with isopropyl, propyl and ethyl amido chains. Several compounds with nanomolar affinity for human melatonin receptors were obtained. (C) 2000 Elsevier Science Ltd.

Substituted 1-(aminomethyl)-2-(arylacetyl)-1,2,3,4- tetrahydroisoquinolines: A novel class of very potent antinociceptive agents with varying degrees of selectivity for κ and μ opioid receptors

This study describes the synthesis of a series of novel substituted 1- (aminomethyl)-2-(arylacetyl)-1,2,3,4-tetrahydroisoquinolines, and discusses their structure-activity relationships (SARs) using binding affinity for opioid receptors and antinociceptive potency as the indices of biological activity. The introduction of a hydroxy substituent in position 5 of the isoquinoline nucleus generated a compound, 40, which is 2 times more potent than the previously disclosed unsubstituted analogue 39 in mouse models of antinociception. A QSAR analysis of the 5-substitution clearly demonstrates that antinociceptive activity is inversely associated with the lipophilicity of the substituents. The substituted compounds described herein are less selective for the κ opioid receptors than the unsubstituted isoquinoline 39. For example, the 5-hydroxy-substituted compound 59 shows high affinity for κ opioid receptors (K(i) κ = 0.09 nM) and a (K(i) μ/K(i) κ ratio of only 5. However, a multiple linear regression analysis demonstrates a lack of correlation between antinociceptive activity and affinity for the μ opioid receptor. On the other hand, the correlation between binding affinity to κ opioid receptor and antinociceptive activity was statistically significant.
