4-Hydroxy-2-methyl-4-phenyl-1,2,3,4-tetrahydroisoquinoline (PI-OH) (1a) and its derivatives form a new class of compounds which possess norepinephrine (NE) potentiating activity. As a new series of compounds, 1-hydroxy-1-phenyl-2,3,4,5-tetrahydro-1H-3-benzazepines (2a—f) were synthesized by the intramolecular Barbier reaction of N-[2-(2-iodophenyl)ethyl]phenacylamines (6a—f) with n-BuLi as a key reaction step. The potentiating activities of the benzazepines 2a—f on the contraction of rat anococcygeus muscle induced by NE were tested. Among the compounds tested in this study, compound 2a showed moderate potentiating activity (the activity ratio was 7.3-fold at 3×10−5 M).
4-羟基-2-甲基-4-苯基-1,2,3,4-四氢异喹啉 (PI-OH) (1a) 及其衍生物形成一类具有去甲肾上腺素 (NE) 增强活性的新型化合物。作为一系列新化合物,通过N-[2-(2 -碘苯基)乙基]苯甲酰胺(6a-f),以正丁基锂为关键反应步骤。测试了苯并氮杂卓2a-f对NE诱导的大鼠尾尾肌收缩的增强活性。在本研究测试的化合物中,化合物2a表现出中等的增强活性(3×10−5 M时活性比为7.3倍)。
