Inhibition of monoamine oxidase by isoquinoline derivatives. Qualitative and 3D-quantitative structure-activity relationships

A series of isoquinolines, N-methyl-1,2-dihydroisoquinolines, N-methyl-1,2,3,4-tetrahydroisoquinolines, 1,2,3,4-tetrahydroisoquinolines, and N-methylisoquinolinium ions were tested as inhibitors of monoamine oxidases A and B. All compounds were found to act as reversible and time-independent MAO inhibitors, often with a distinct selectivity towards MAO-A. As a class, the N-methylisoquinolinium ions were found to be the most active MAO-A inhibitors, with N-methyl-6-methoxyisoquinolinium ion emerging as a potent (IC50 = 0.81 muM) and competitive MAO-A inhibitor. Comparative molecular field analysis (CoMFA, a 3D-QSAR method) of MAO-A inhibition was performed using the data reported here and in the literature. Using the steric and lipophilic fields of the inhibitors, quantitative models with reasonable predictive power were obtained that point to the importance of steric, lipophilic, and polar interactions in modulating MAO-A inhibitory activity.

Inhibition of phenylethanolamine n-methyltransferase (PNMT) by aromatic hydroxy-substituted 1,2,3,4-tetrahydroisoquinolines: Further studies on the hydrophilic pocket of the aromatic ring binding region of the active site

In a continuation of studies directed toward characterizing the hydrophilic pocket within the aromatic ring binding region of the active site of phenylethanolamine N-methyltransferase (PNMT), 5-, 6-, 7-, and 8-hydroxy-1,2,3,4-tetrahydroisoquinoline were prepared and evaluated as substates and inhibitors of PNMT. In order to discern the necessity of an acidic hydrogen for interaction at this pocket the corresponding methyl ethers were also evaluated. The enhanced affinity of 7-hydroxy-1,2,3,4-tetrahydroisoquinoline (16) versus tetrahydroisoquinoline (13) itself indicates that a hydrophilic pocket exists off of carbon C7 in bound tetrahydroisoquinolines. The diminished affinity of the corresponding methyl ether is consistent with a requirement for the acidic hydrogen of 16 for interaction of the aromatic hydroxyl at site. From the relative activities of the other regioisomeric aromatic hydroxyl-substituted tetrahydroisoquinolines, their corresponding methyl ethers, and 6,7-dihydroxy-1,2,3,4-tetrahydroisoquinoline, it appears that the hydrophilic pocket is spatially compact with respect to bound tetrahydroisoquinolines and is surrounded by larger areas of lipophilic character. To allow a comparison of the results of this study with previous data on bound beta-phenylethylamines, the methyl ethers of 5-, 6-, 7-, and 8-hydroxy-exo-2-aminobenzonorbornene and of 5- and 6-hydroxy-anti-9-aminobenzonorbornene were also evaluated for their activity as substrates and inhibitors for PNMT. The results of this study are in agreement with previous findings for bound beta-phenylethylamines and support the conclusion that the natural substrate for PNMT, norepinephrine, has a different active site binding orientation than most known substrates and competitive inhibitors of the enzyme.
