Starting from the methyl ester of β-(bromomethyl)-γ-phenylbutyric acid and its m-fluoro derivative, we have prepared 2-[4[3-(p-fluorobenzoyl)-1-propyl]piperazin-1-ylmethyl]tetraline (QF0105B) and the corresponding 7-fluoro derivative (QF0106B). The affinities of these compounds for D1 and D2 dopamine and 5-HT2A receptors was evaluated in vitro. The afinities of QF0105B and QF0106B for D2 receptors are less than that of haloperidol (pKi's for inhibition of [3H]spiperone binding : 7.72, 7.06 and 8.30, respectively) but all three compounds have similar affinities for 5-HT2A receptors (pKi'S for inhibition of [3H]ketanserine binding : 7.70, 7.36 and 7.70, respectively).
从 β-(溴甲基)-γ-苯基丁酸甲酯及其间氟衍生物开始,我们制备了 2-[4-[3-(对氟苯甲酰基)-1-丙基]哌嗪-1-基甲基]四氢萘 (QF0105B) 和相应的 7-氟衍生物 (QF0106B)。体外评估了这些化合物对 D1 和 D2 多巴胺受体以及 5-HT2A 受体的亲和力。QF0105B 和 QF0106B 对 D2 受体的亲和力低于氟哌啶醇(抑制 [3H]spiperone 结合的 pKi 值分别为 7.72、7.06 和 8.30),但这三种化合物对 5-HT2A 受体的亲和力相似(抑制 [3H]ketanserine 结合的 pKi 值分别为 7.70、7.36 和 7.70)。
