4-tetrahydroisoquinoline-7-sulfonamide (21,SK&F 29661) were prepared and studied for their ability to inhibit phenylethanolamine N-methyltransferase (PNMT) in vitro. The choice of substituents on the 7-phenyl group of the sulfonanilides was based on the Topliss approach to structure-activity relationship studies. Information about the importance of an acidic hydrogen atom on the sulfonamide nitrogen atom was obtained
制备了与1,2,3,4-四氢异喹啉-7-磺酰胺(21,SK&F 29661)有关的1,2,3,4-四氢异喹啉-7-磺酰苯胺(1-14)并研究了它们抑制苯基乙醇胺N的能力。 -甲基转移酶(PNMT)在体外。磺酰苯胺的7-苯基上取代基的选择是基于Topliss方法进行的结构-活性关系研究。有关酸性氢原子对磺酰胺氮原子重要性的信息,可从叔N-甲基磺酰苯胺的制备和测试中获得(15)。制备并测试了其他7位含硫取代基的THIQ(1,2,3,4-四氢异喹啉),它们由SK&F 29661(16-18)的7-N-苄基和7-N-苯乙基衍生物以及7- (苯甲硫基)-和7-(苯乙磺酰基)-THIQ(19和20)。
