airways. From a systematic variation of the capsazepine structure, divided into four regions, SARs were established. This paper concerns the chlorination of the A-ring as well as the replacement of the catechol with bioisosteric groups. It is revealed that chlorination of the A-ring has a profound effect on activity. Moreover, di-chlorination of the 6,7-dihydroxy-1,2,3,4-tetrahydroisoquinoline structure
辣椒素及其衍生物和类似物是人类小气道收缩的一般抑制剂。从辣椒素结构的系统变化分为四个区域,建立了SAR。本文涉及A环的氯化以及生物等位基团取代邻苯二酚。揭示了A环的氯化对活性有深远的影响。此外,与卡塞平相比,对6,7-二羟基-1,2,3,4-四氢异喹啉结构进行二氯化处理会导致效力增加10倍。
