  Effects of a 3-Alkyl-, 4-Hydroxy- and/or 8-Aromatic-substituent on the Phenylethanolamine N-Methyltransferase Inhibitor Potency and α2-Adrenoceptor Affinity of 2,3,4,5-Tetrahydro-1H-2-benzazepines

  摘要：

  2,3,4,5-Tetrahydro-1H-2-benzazepine (THBA; 1) is nearly 100-fold more selective an inhibitor of phenylethanolamine N-methyltransferase (PNMT, EC 2.1.1.28) versus the alpha (2)-adrenoceptor than is 1,2,3,4-tetrahydroisoquinoline (THIQ; 2) (1: PNMT K-i = 3.3 muM, alpha (2)-adrenoceptor K-i = 11 muM, selectivity [alpha (2) K-i/PNMT K-i = 3.3; 2: PNMT K-i = 9.7 muM, alpha (2) K-i = 0.35 muM, selectivity 0.036;). Since the PNMT inhibitory activity and selectivity of THIQ were enhanced by the introduction of a hydrophilic electron-withdrawing 7-substituent and a 3-alkyl-substituent, a similar study was conducted on THBA. 8-Nitro-THBA (3) was found to be as potent an inhibitor of PNMT as its THIQ analogue (21) and to be more selective due to its reduced alpha (2)-adrenoceptor affinity (3: PNMT K-i = 0.39 muM, alpha (2) K-i = 66 muM, selectivity = 170; 21: PNMT K-i = 0.41 muM, (alpha (2) K-i = 4.3 muM, selectivity = 10). Introduction of a 3-alkyl substituent on the THBA nucleus decreased both the alpha (2)-adrenoceptor affinity and the PNMT inhibitory activity, suggesting an area of steric bulk intolerance at both sites. 4-Hydroxy-THBA (15), which can be considered a conformationally-restricted analogue of 3-hydroxymethyl-THIQ (30), exhibited poorer PNMT inhibitory activity and less selectivity than 30 (15: PNMT K-i = 58 muM, alpha (2) K-i = 100 muM, selectivity = 1.7; 30 PNMT K-i = 1.1 muM, alpha (2) K-i = 6.6 muM, selectivity = 6.0). While the addition of an 8-nitro group to 15 increased the selectivity of 16 as compared to its THIQ analogue (31), it was not as potent at PNMT nor as selective as 8-nitro-THBA (3) (16, PNMT K-i = 5.3 muM, alpha (2) K-i = 680 muM, selectivity = 130; 31: PNMT K-i = 0.29 muM, alpha (2) K-i = 19 muM, selectivity = 66). Compound 3 is the most selective (PNMT/alpha (2) and one of the more potent at PNMT compounds yet reported in the benzazepine series, and should have sufficient lipophilicity to penetrate the blood-brain barrier (CLogP = 1.8).

  This invention concerns a process for preparing 2- benzazepine compounds which inhibit the enzyme phenylethanolamine N-methyltransferase and show activity in reducing anxiety. The compounds produced have substituents in the 8- and/or 9-positions, and optionally substituents in the 1- and 2-positions. The compounds are prepared by debenzylating an appropriately substituted N-benzyl 2-benzazepine with optional acylation and reduction, or with optional ozidation and alkylation of the debenzylated product to introduce 2- and 1-position substituents, respectively. Acid addition salts of the compounds are also prepared.

  本发明涉及一种制备 2-苯并氮杂卓化合物的工艺，该化合物可抑制苯乙醇胺 N-甲基转移酶，并具有减轻焦虑的活性。所制备的化合物在 8 位和/或 9 位上有取代基，在 1 位和 2 位上也有取代基。这些化合物的制备方法是将适当取代的 N-苄基 2-苯并氮杂卓进行去苄基化，然后进行任选的酰化和还原，或对去苄基化产物进行任选的羰基化和烷基化，以分别引入 2 位和 1 位取代基。还可制备这些化合物的酸加成盐。
