tether between the piperidyl moiety and the terminal aromatic ring is important for potent antihypertensive activity. Oral administration of 6-fluoro-1-isopropyl-2-[1-(2-phenylethyl)piperidin-4-yl]carbonyl}-1,2,3,4-tetrahydroisoquinoline (3b) to spontaneously hypertensive rats (SHR) elicited antihypertensive effects without inducing reflex tachycardia, which is often caused by traditional L-type Ca²⁺
合成了一系列1-异丙基-1,2,3,4-四氢异喹啉衍生物,并在离体豚鼠右心房评估了它们的心动过缓活性。结构-活性关系研究表明,引入合适的取代基及其在1,2,3,4-四氢异喹啉环上的位置对于有效的体外活性至关重要。此外,哌啶基部分和末端芳族环之间的系链对于有效的抗高血压活性很重要。对自发性高血压大鼠(SHR)口服6-氟-1-异丙基-2-[1-(2-(苯基苯基)哌啶-4-基]羰基} -1,2,3,4-四氢异喹啉(3b)在不引起反射性心动过速的情况下引起降压作用,这通常是由传统的L型Ca²L通道阻滞剂引起的。
