located on the 4-position of the piperidine ring. Analogues incorporating pyrrolidine in lieu of piperidine were also prepared. Electrical recordings using cloned receptors expressed in Xenopus oocytes show that high-potency antagonists at the NR1A/2B subtype are obtained employing N-(omega-phenylalkyl)-substituted 4-(4-hydroxyphenyl)piperidine, 4-(4-hydroxybenzyl)piperidine, and (+/-)-3-(4-hydroxyphenyl)pyrrolidine
NMDA受体(NR1A / 2B)的1A / 2B亚型的拮抗剂通常是小分子,由在杂环氮上带有ω-苯基烷基取代基的4-苄基或4-苯基哌啶组成。这些拮抗剂中有许多,例如艾芬地尔(ifenprodil)(1),在ω-苯基上带有4-羟基取代基。在该研究中,该4-羟基取代基的位置从ω-苯基转移至位于哌啶环的4-位上的苄基或苯基。还制备了掺入吡咯烷代替哌啶的类似物。使用在非洲爪蟾卵母细胞中表达的克隆受体的电记录显示,使用N-(ω-苯基烷基)-取代的4-(4-羟基苯基)哌啶,4-(4-羟基苄基)哌啶可获得NR1A / 2B亚型的高效拮抗剂,和(+/-)-3-(4-羟基苯基)吡咯烷,例如21(IC(50)= 0.022 microM),33(IC(50)= 0.059 microM)和40(IC(50)= 0.017 microM ), 分别。与NR1A / 2A或NR1A / 2C亚型相比,这些高效的拮抗剂在NR1A
