  3-Hydroxymethyl-7-(N-substituted aminosulfonyl)-1,2,3,4-tetrahydroisoquinoline Inhibitors of Phenylethanolamine N-Methyltransferase that Display Remarkable Potency and Selectivity

  摘要：

  Six 3-hydroxymethyl-7-(N-substituted aminosulfonyl)-1,2,3,4-tetrahydroisoquinolines (16-21) were synthesized and evaluated for their phenylethanolamine N-methyltransferase (PNMT) inhibitory potency and affinity for the alpha(2)-adrenoceptor. The addition of nonpolar substituents to the sulfonamide nitrogen of 9 (3-CH2OH-7-SO2NH2-THIQ) led to inhibitors (16-21) that have high PNMT inhibitory potency and high selectivity, and most of these (16-21) are predicted, on the basis of their calculated log P values, to be able to penetrate the blood-brain barrier. Compounds N-trifluoroethyl sulfonamide 20 (PNMT K-i = 23 nM) and N-trifluoropropyl sulfonamide 21 (PNMT Ki = 28 nM) are twice as potent at inhibiting PNMT compared to 9 and display excellent selectivity (alpha(2) K-i/PNMT K-i greater than or equal to 15 000).
