Solvent Effects on Lower Excited States of N-Methyl-1,2,3,4-tetrahydroisoquinoline

The electronic spectra of the title compound, N-methyl-1,2,3,4-tetrahydroisoquinoline (NMTHIQ), i.e., a bichromophoric molecule with benzene and tertiary alkylamine groups, were observed in various media.Five or more absorption bands as well as two kinds of fluorescences were observed.These were assigned to transitions involving 1La and 1Lb states of the benzene (Ph) group, two kinds of Rydberg states of the amine (N) group, and a Ph* <- nN type charge-transfer (CT) state, consistent with observed solvent effects.Excitation-wavelength dependences of fluorescence quantum yields were also measured, indicating peculiar solvent effects on both radiative and radiationless transitions, especially on a fast internal conversion from the 1Lb state to the ground state, probably via the CT state.The protonation effect on the amine group is apparently inconsistent with an earlier idea that the amine group suffers hypsochromic effect when it is protonated.This result was explained by assuming a double-minimum potential well for the hydrogen-bond structures: < formular>; the latter conformation gives a novel protonation effect preserving the electron-donating nN orbital.

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.
