Abstract
本文介绍(3R,S)-型或(3R)-型(I)化合物或其药物上可接受的盐的制备方法,或(I)如下:
这些化合物用于治疗与改变平滑肌运动型和/或紧张有关疾病。
Description
本发明涉及某些1,3-二取代哌啶衍生物。
更具体地讲,本发明涉及用作选择性毒蕈硷受体拮抗剂的1-芳基乙基-3-取代哌啶衍生物。
英国专利780,027号公开的一些化合物中,用作催化剂的3-(二苯甲氧基)-和3-(咕吨氧基)-N-芳烷基哌啶,其所用治疗剂量不起解痉作用。在该专利范围内没有合成或举例说明N-苯乙基取代的实例。
美国专利2,974,146号提供的N-芳烷基-3-哌啶基二苯甲基醚具有镇静活性,并延长巴比妥盐的安眠作用,指出只有相应的季铵盐具有胃肠解痉作用。虽然把N-苯乙基-3-哌啶基二苯甲基醚列为“由该发明提供的具体化合物”,但没有提供制备方法或药理数据,显然,该化合物实际上从没制得过。
现在,意想不到地发现由本发明提供的1-(苯乙基)和1-(2-杂芳基乙基)-3-取代哌啶衍生物是毒蕈碱受体拮抗剂,它选择性作用于贲门毒蕈碱位点之上的平滑肌毒蕈碱位点,并不具有任何明显的抗组胺活性。因此,这些化合物用于治疗与改变平滑肌的能动性和/或紧张程度有关的疾病,例如可在肠、气管和膀胱处出现平滑肌紧张。这类病包括肠过敏综合症,憩室病,尿失禁,食道紧缩症和慢性气管阻塞症。

可通过包括下述反应的多种途径制备式(Ⅰ)化合物:
路线A
这一路线说明如下:

该反应最好在回流温度下,于酸受体存在的适宜溶剂如乙腈中进行。所述酸受体如碳酸钠或碳酸钾,碳酸氢钠,三乙胺或吡啶。一般要求反应温度为60-120℃,在回流下最便于实施该反应。碘代通常是最适宜离去基团,但由于原料(Ⅲ)一般最容易得到氯化物或溴化物,因此常常用化合物(Ⅲ)的氯化物或溴化物,但是在碘化物(如碘化钠或碘化钾)存在下,最适于实施该反应。就最佳工艺而言,在碳酸钠和碘化钠存在下,于乙腈中将化合物(Ⅱ)和(Ⅲ)一起回流,其中化合物(Ⅲ)为溴化物或氯化物。产品(Ⅰ)可用常规方法分离和纯化。
根据所要求产品是3R,S-还是3R-型而决定应使用3R,S-或3R-型起始原料(Ⅱ)。
式(Ⅱ)原料可用常规方法得到,如制备方法1至7所介绍的。式(Ⅲ)原料是众所周知的化合物,可用常规技术制备。在下文制备部分介绍用于实施例的式Ⅲ新颖原料的制备。
路线B

R和R的定义同式(Ⅰ):按照需要再次使用3R,S-或3R-型化合物(Ⅳ)。
按常规,一般用无机还原剂例如氢化铝锂、氢化铝(由氢化铝锂和
浓硫酸直接制取AlH3)或乙硼烷,在适宜的有机溶剂如四氢呋喃、醚或二噁烷中进行该还原反应。该反应温度最好在0℃至室温。虽然一般不必加热,如有必要,可在反应混合物的回流温度下进行该反应。产品(Ⅰ)可按常规方法分离和纯化。
式(Ⅳ)原料(3R,S-或3R-)可用常规技术制备,其中包括下文制备部分介绍的那些方法(特别请参见制备8至10)。
路线C
这一路线说明如下:
R和R1的定义同式(Ⅰ),Q是离去基团(例如路线A所述)。在本路线中,Q最好是Cl或Br。其中式Ⅴ化合物颇具活性,进而在室温下完成该反应。必要时,该反应混合物可加热至160℃,以加速反应。尽管在某些情况下,如实施例8(B),个别有机溶剂的存在是没必要的,但该反应可以在适宜有机溶剂如二氯甲烷中进行。化合物(Ⅰ)按常规分离和纯化。
原料(Ⅴ)可是已知化合物,也可按常规方法制得。化合物(Ⅵ)可按常规方法制备,例如在制备15-16中介绍的技术。
根据所要求化合物(Ⅰ)是3R,S-还是3R-型而决定应使用3R,S-或3R型原料(Ⅵ)。
路线D
这一路线用于制备式中R是2或4-吡啶基或吡嗪基的化合物,如下所述:
R1和R5的定义同式(Ⅰ)。很清楚,乙烯基必须连接于吡啶环的2-或4-位。
该反应一般在适宜的有机溶剂如1-丁醇中,加热至160℃,最好是80-140℃下进行。使用碱性(最好是可溶于有机溶剂的强碱如N-苄基三甲基氢氧化铵〔商标“Triton B”〕)催化剂或酸性(最好是C1-4链烷酸)催化剂是有效的。最佳方法是在碱性催化剂如“Triton B”的存在下,于有机溶剂中回流该反应物。
路线E
式中R是5-氨基甲酰基-2-噻吩基的化合物也可按如下路线制备:
R1的定义同式(Ⅰ)
式(Ⅰ)中R是取代苯基的某些化合物可以转化为式(Ⅰ)的其它化合物,详述如下:
(a)苯基的-CO2(C1-4烷基)取代基可还原为-CH2OH,氢化铝锂是最适宜还原剂。该反应一般在0℃至室温下,于适宜的有机溶剂如醚中进行,一般使用其甲酯形式的原料最为方便。

(e)苯基的硝基取代基可按常规方法还原为氨基。最佳还原剂是氯化亚锡二水合物,该反应一般在有机溶剂如乙醇中回流进行。
(f)苯基的氨基取代基可以通过与C1-4链烷磺酰氯或C1-4链烷磺酰溴或C1-4链烷磺酸酐反应,转化为-NHSO2(C1-4烷基)。酸受体,如吡啶、三乙胺、碳酸氢钠或碳酸钠或碳酸钾的存在为最佳。尤其当使用磺酰氯时,在吡啶中进行该反应常常是最方便的,该吡啶起溶剂和酸受体作用。通常不必加热,一般在室温下,就能以令人满意的速度进行该反应。

(h)苯基的氨基取代基一般可在有机溶剂如二噁烷中,与硫酰胺回流反应,转化为氨磺酰。
(i)羟基取代基可先与强碱如氢化钠反应,再与C1-4烷基碘反应,转化为C1-4烷氧基。该反应最好在约室温下,于溶剂如二甲基甲酰胺中进行。
(j)式中n是0、1或2的-(CH2)nOH的羟基取代基通过与异氰酸
C1-4烷基酯反应,可转化为-(CH2)nOCONH(C1-4烷基)。该反应一般在约室温下,于溶剂如二氯甲烷中进行。
(k)苯基的羟甲基取代基通过先与亚硫酰氯反应,再与氨或适当的胺R8R9NH反应,可转化为式中R8和R9各自分别为H或C1-4烷基的-CH2NR8R9。与亚硫酰氯的反应一般在溶剂如二氯甲烷中加热进行,最好回流加热。与氨或胺的反应一般在溶剂如乙醇中,在约室温下进行。
(l)乙酰取代基可通过与甲基锂、甲基镁化溴、甲基镁化碘或甲基镁化氯反应,转化为-C(OH)(CH3)2。该反应一般在0℃至室温下,于溶剂如醚中进行。
(m)碘代取代基一般可在约室温下,通过在含碱〔例如碳酸钾〕和钯(Ⅱ)催化剂〔例如双(三苯膦)氯化钯(Ⅱ)〕的C1-4烷醇中与一氧化碳反应,转化为C1-4烷氧基羰基。
(n)苯基的氰基取代基一般可用H2/Pd/C溶于含少量浓盐酸的乙醇溶液,通过催化氢化作用,还原为氨甲基。
(o)式中n是0、1或2的-(CH2)nNH2取代基通过与异氰酸C1-4烷酯反应,转化为式-(CH2)nNHCONH(C1-4烷基)取代基。该反应一般在约室温下,于溶剂如二氯甲烷中进行。
(p)C1-4烷氧基取代基,最好是甲氧基可以在强碱如氢化钠存在下,通过与C1-4链烷硫醇反应,转化为羟基。一般在适宜溶剂如二甲基甲酰胺中回流反应物,进行该反应。丁烷硫醇为最佳硫醇。
可按如下所述测定用作毒蕈碱受体拮抗化合物的选择性。
处死雄豚鼠,取出回肠、气管、膀胱和右心房,并在保持1g拉力下悬挂于生理盐水溶液中,在32℃下充气95%O2和5%CO2。用等张(回肠)或等张转换器(膀胱和气管)记录回肠、膀胱和气管的挛缩。由等张记录挛缩得到右心房自然跳动的挛缩频率。
对每种兴奋剂剂量采用1-5分钟接触时间,直至获得最大应答值由
此确定对乙酰胆碱(回肠)或碳酰胆碱(气管、膀胱和右心房)的剂量应答曲线。排去器官浴的水,再灌满含最低剂量试验化合物的生理盐水溶液。使该试验化合物与组织平衡20分钟,重复兴奋剂剂量应答曲线,直至得到最大应答值。排去器官浴的水,再灌满含第二种浓度试验化合物的生理盐水溶液,并重复上述方法。一般对每种组织评价该试验化合物四种浓度。
测定使兴奋剂浓度加倍以产生最初应答的试验化合物浓度(pA值,Arunlakshana and Schild(1959),Brit.J.Pharmacol.,14,48-58)。采用上述分析技术测定毒蕈受体拮抗剂的组织选择性。
通过与心率的变化相比较,在麽醉狗体内测定对于兴奋剂诱发的支气管收缩,肠和膀胱的挛缩作用的对抗作用。用神志清醒的狗确定化合物对心率、瞳孔直径和肠运动性影响的口服活性。
给鼠静脉或腹膜内施药后,确定化合物对其他胆碱能位点的亲合作用。从而测定引起双倍瞳孔尺寸的剂量,以及抑制50%静脉氧化震颤素引起的多涎和震颤应答的剂量。
就施药于人而言,在治疗或预防与改变平滑肌能动性和/或紧张程度有关疾病中,该化合物口服剂量对一般成年患者(体重70kg)每天一般为3.5至350mg。所述疾病如肠过敏综合症,憩室疾病,尿失禁,食管紧缩和慢性阻塞气管病。因此,对典型的成年患者来说,每个片剂或胶囊一般含活性化合物1至250mg,置于适宜的药物可接受的赋形剂或载体内,以单次剂量或多次剂量形式,每天一次或多次给药。静脉注射的剂量范围按要求每单剂量为0.35至35mg。实际上,由医师确定最适合于每个患者的实际剂量,它随具体患者的年龄、体重和反应而改变。上述剂量用于一般病例,当然特殊病例应得较高或较低剂量,并且这也在本发明范围内。
对人类应用而言,式(Ⅰ)化合物可单独给药,但一般与药用载体
