Abstract
本发明公开了式I所示的化合物或其药学上可接受的盐在制备治疗抑郁症的药物中的应用。具体涉及式I化合物对5-HT、NE及DA再摄取具有三重抑制作用,其抗抑郁作用比目前临床上使用的单一作用靶点的抗抑郁药(如氟西汀)及双重作用靶点的抗抑郁药(如度洛西汀)可能具有更广的适应症及较小的神经毒副作用。
Description
本发明涉及[(芳氧基)(杂芳基)]甲基哌啶衍生物在制备治疗抑郁症的药物中的应用。
本发明公开的通式化合物已在专利EP2390248中公开,用于治疗淀粉样蛋白。淀粉样蛋白是阿尔兹海默氏症发病机制的一种假说,淀粉样蛋白沉积可导致阿尔兹海默氏症的发病,降低淀粉样蛋白在大脑内的蓄积量可延缓或者减轻阿尔兹海默氏症的症状。而淀粉样蛋白与抑郁的发病机制以及治疗没有相关性。
抑郁症是当今危害人类身心健康最常见的精神疾病。目前全世界抑郁症患者已占世界人口的3‐5%。预计到2020年,抑郁症可能将成为仅次于心脏病的第2大疾病。
药物治疗是抑郁症治疗的主要手段。主要治疗药物包括:三环类抗抑郁药,如丙咪嗪等;单胺氧化酶抑制剂,如吗氯贝胺等;选择性5‐HT再摄取抑制剂,如氟西汀等;选择性NE再摄取抑制剂,如波瑞西汀等;5‐HT及NE双重再摄取抑制剂,如度洛西汀等。
尽管已有不少的抗抑郁药物用于临床,但因某些药物反应率低,起效时间长,并有潜在的副作用,仍有相当的病人经各种治疗无效,有的仍需求助于电惊厥治疗。因此,抗抑郁药的开发仍是新药研究的热点,许多制药业投入大量的资金用于开发更好的治疗药物。
已有多方研究[Carlier P R,et al,Bioorg.Med.Chem.Lett.,1998,8(5):487;Tamiz A P,et al,J.Med.Chem.,2000,43(6):1215;Skolnick P,et al,Eur.J.Pharmaco.,2003,461(2‐3):99]表示,在双重再摄取抑制剂中加入对多巴胺再摄取的作用后,对治疗抑郁症可取得起效快,副作用小,作用强的积极效果。
目前,在抗抑郁症新药研究方面,选择性三重再摄取抑制剂的研究越来越受到重视,有望解决现有抗抑郁药的效应滞后问题,及提高有效性,增加安全性等问题。选择性三重再摄取抑制剂,是指能够同时选择性抑制与抑郁症密切相关的三种单胺递质5‐HT,NE和DA的再摄取的化合物。
三重再摄取抗抑郁药目前还处于临床研究阶段。如DOV Pharmaceutical公司开发的DOV216303处于III期临床。葛兰素史克公司与NeuroSearch公司共同开发的NS‐2359目前处于二期临床。这些三重再摄取抑制剂具备效率高,起效快等优势,正成为抗抑郁领域关注的重点。

动物试验结果显示,本发明所涉及的若干化合物具有比阳性药度洛西汀更优的抗抑郁活性。
本发明的化合物可采用如下的方法进行合成。
合成路线一:
具体来说,本合成路线以4‐哌啶甲酸乙酯为起始原料,首先和苯甲酰氯在三乙胺存在下,冰浴反应5h,进行胺基保护得到中间体1‐苯甲酰基‐4‐哌啶甲酸乙酯(A)。
化合物(A)用氢氧化钠于乙醇中在室温下水解3h,得到中间体1‐苯甲酰基‐4‐哌啶甲酸(B)。
化合物(B)和过量氯化亚砜在室温下搅拌过夜制备哌啶甲酰氯(C)。
化合物(C)在无水三氯化铝存在下和噻吩(或呋喃)冰浴条件下发生傅克酰基化反应,得到羰基化物(D)。
化合物(D)用硼氢化钠在甲醇中还原得羟基化物(E)。
化合物(E)溶于DMSO,在碱(KOH或NaH)的作用下和卤代烃于90℃左右反应3‐12h,发生亲核取代,经柱层析纯化得到醚化产物(F)。
或者通过Mitsunobu反应,用化合物(E)在偶氮二甲酸二乙酯(DEAD)和三苯基膦的存在下与相应的取代酚冰浴下发生缩合,制备化合物(F)。
化合物(F)用NaOH的乙醇溶液回流处理12h脱除酰基保护,得目标物的游离碱(G)。
游离碱(G)用盐酸或草酸等有机或无机酸处理,得到盐(J)。
对于含有3‐哌啶环的化合物,则主要采用如下合成路线:
合成路线二
此合成路线以3‐哌啶甲酸乙酯为原料经胺基保护,氯代,傅克反应,羰基还原制备化合物(12),合成方法与路线一相似。
由于化合物(Q)羟基酸性较弱,难以在碱性条件下和卤代烃发生亲核反应,故本路线采用Mitsunobu反应,即化合物(Q)在偶氮二甲酸二乙酯(DEAD)和三苯基膦的存在下与取代酚冰浴下发生缩合,制备化合物(W)。后者通过脱保护,成盐等反应得到目标物(Z)。

实施例36 优选化合物动物体内抗抑郁活性研究
采用“获得性绝望实验”中的小鼠悬尾实验(tail suspetion test)和小鼠强迫游泳“不动”实验(forced swimming test)以度洛西汀作为阳性对照药,对优选化合物进行体内抗抑郁作用的初步研究。
36.1 小鼠悬尾实验(TST)
各待测化合物的药物剂量先设定为3mg/kg、10mg/kg及30mg/kg,上述药物剂量若产生明显的效果(减少小鼠的不动时间),则将剂量适量下调,若未产生效果(没有减少小鼠不动时间)则将剂量上调,或在以上3个剂量中根据受试剂量之间的比例插加受试药物剂量,根据具体情况定。盐酸度洛西汀和各待测化合物溶于50%的PEG400中,然后超声30min。
实验前1‐2天筛选出体重合格的小鼠并随机分组,每组10只,设立溶媒对照组和受试药各给药组。各给药组在实验前1h采用灌胃(ig)给药,实验时间是09:00‐1500,给药完毕后,将小鼠用胶布粘贴距尾尖1cm处,然后悬挂距实验台50cm处6min,摄像头录像后,人工分析并记录小鼠后4min内的不动时间。
实验数据用表示,采用EXCEL统计软件,先进行F‐test方差齐性检验,若方差齐(P>0.05)则进行T‐test等方差检验;若方差不齐(P<0.05),则进行T‐test异方差检验,以P<0.05为差异有显著性。
36.2 小鼠强迫游泳实验(FST)
各待测化合物的药物剂量先设定为10mg/kg及30mg/kg,上述药物剂量若产生明显的效果(减少小鼠的不动时间),则将剂量适量下调,若未产生效果(没有减少小鼠不动时间)则将剂量上调,或在以上2个剂量中根据受试剂量之间的比例插加受试药物剂量,根据具体情况定。盐酸度洛西汀和各待测化合物溶于50%的PEG400中,然后超声30min。
实验前几天筛选出体重合格的小鼠并随机分组,每组10只,设立溶媒对照组、阳性对照组和受试药各给药组。各给药组采用灌胃(ig)给药,每次实验前1h给药。给药完毕后,将小鼠放入透明的强迫游泳圆筒(高25cm,直径10cm)中6min,水深15cm,水温23~25℃。摄像头录像人工分析并记录小鼠后4min内的不动时间,视频分析者不知道动物的给药情况。
