Description

新的咪唑衍生物及其制备方法
本发明专利申请是申请日为1994年12月1日,申请号为94194450.6,名称为“新的咪唑衍生物及其制备方法”的发明专利申请的分案申请。
本发明涉及新的咪唑衍生物类治疗药,特别是抗胆碱能药类咪唑衍生物,尤其是毒蕈碱型乙酰胆碱受体的选择性拮抗剂,它们的制备方法,以及含有它们的药物组合物。
抗胆碱能药显示抗痉作用及抗分泌作用,用作肠道、膀胱等功能障碍的治疗药物。目前已知阿托品等生物碱、奥昔布宁和溴丙胺太林等氨基烷醇酯类,它们的季铵盐等是抗胆碱能药,而且它们是毒蕈碱型乙酰胆碱受体的阻滞剂。然而由于它们的拮抗作用器官选择性较差,会引起副作用,这成为它们的问题。因此,临床上要求开发具有高度选择性的抗胆碱能药。
虽然有报告说5-〔1-(咪唑)甲基〕-3,3-二取代-2(3H)-呋喃酮衍生物是毒蕈碱型乙酰胆碱受体的拮抗剂,它们带有咪唑基取代基(日本未审查专利公开号平4-103581),但这些化合物的结构不同于本发明的化合物,且它们也不具有足以令人满意的活性。
本发明提供的药物对于平滑肌的毒蕈碱型乙酰胆碱受体比对心脏毒蕈碱型乙酰胆碱受体具有更高的选择性和更强的拮抗活性。
为了上述目的,本发明者对咪唑衍生物作了精心研究。结果发现通式1表示的咪唑衍生物

〔其中R1是可带有取代基的苯基或噻吩基,R2为氰基、羧基、CONR7R8基团(其中R7和R8各独立地表示氢原子或低级烷基,或R7和R8可由亚烷基链(可含有杂原子)形成环)或COOR9基(其中R9是低级烷基),R3是氢原子或低级烷基,R4,R5及R6各独立地表示氢原子、可带有取代基的低级烷基,或者环烷基,或者在R5及R6位可与苯环形成一稠环,而m为1至6的整数〕,或通式2表示的咪唑衍生物

因此本发明的化合物可用于治疗消化道运动障碍如过敏性肠综合症、憩室病、功能性腹泻、食管弛缓不能及贲门痉挛,治疗胆道和尿道痉挛、尿失禁等,治疗慢性呼吸道阻塞性疾病等。

“低级烷基的取代基”一词系指卤素、低级烷氧基、羟基、苯基等。
“环烷基”一词系指含3至8个碳原子的脂环烃类,如环丙基和环己基。

1.对豚鼠回肠和心房的抗胆碱能作用
雄性Hartley豚鼠经打击头部并放血处死。
在32℃将回肠片(约3cm长)悬挂在含有以95%O2和5%CO2的混合物平衡的Tyrode氏溶液的器官浴槽中。
在张力为1g时等张地记录对累积加入浴液中的乙酰胆碱(ACh)的效应。在不加供试化合物,以及在加入ACh前5分钟浴中不同浓度的供试化合物存在时测定ACh的剂量一效应曲线。
根据Schild法(Arunlakshana,O.及Schild,H.O.(1959),Brit.J.Pharmacol.,14;48~58)测定供试化合物对毒蕈碱型受体的亲和力(pA2)。
在32℃于含以95%O2和5%CO2处理的Tyrode氏溶液的器官浴槽中在0.5g张力下悬挂离体心房。
在累积加入ACh的过程中得到剂量一效应曲线,然后在不同浓度的供试化合物存在下重复测定,平衡时间为10分钟。
如上所述,测定供试化合物的亲和性。结果列于表8。

本发明的化合物对豚鼠回肠的毒蕈碱受体具有高亲和性,而对心脏受体则亲和性要低得多。
特别是实施例8、11和14的化合物对回肠受体的亲和性与对心脏受体的亲和性相比要大10倍。
2.对膀胱节律性收缩的作用
在氟烷麻醉下将雄性Wistar大鼠固定于仰卧位,通过沿中线开口于下腹尖端的小切口将带气球尖端的导管插入膀胱,然后用荷包口缝术缝口。导管从缝合的腹部切口的上端引出,与压力换能器连接。
气球中灌以约0.1~0.3ml的水。在膀胱的节律性收缩稳定于膀胱内压阈值之后,于十二指肠内给予供试化合物。由膀胱收缩幅度的减小估计其抑制作用。本发明的化合物在剂量为0.03mg/kg或更大时能使膀胱的收缩幅度减小。
3.对氨基甲酰甲基胆碱诱导的腹泻的作用
