    摘要:
    已经合成了四个相关的含角稠合哌啶环的取代的喹喔啉二酮系列化合物,作为α-氨基-3-羟基-5-甲基-4-异恶唑丙酸(AMPA)受体拮抗剂,具有潜在的神经保护剂的作用,主要用于急性治疗。中风。测试了这些化合物对AMPA,红藻氨酸和对苯丙氨酸不敏感的甘氨酸受体位点的亲和力。在AMPA结合中,最有效的化合物是27a(PNQX,IC50 = 63 nM),亲和力可与文献标准1(NBQX,IC50 = 52 nM)相比。来自9-氮杂系列的其他6-硝基类似物对AMPA受体的亲和力相当,例如6-硝基-8-氮杂衍生物(如13a)(iPNQX,IC50 = 290 nM)。27a的受体结合图谱不同于1的受体图谱,因为27a在N-甲基-D-天冬氨酸(NMDA)受体的甘氨酸位点具有显着的亲和力,而1基本上是无活性的。相对于AMPA受体,三种化合物26c,26d和26e对海藻酸盐具有中等选择性。叠加本文和文献中报道

  • A method for treating tension-type headache
    申请人:HEADEXPLORER ApS
    公开号:EP1829539A2
    公开(公告)日:2007-09-05
    Tension-type headache is treated by interacting with neuronal transmission in relation to pain in connection with headache in a way which prevents or decreases sensitization of second order nociceptive neurons. In particular, treatment is performed by administration of an effective amount of a substance which prevents or decreases central sensitization. Important examples of such substances are substances which interact with glutamate neurotransmission, such as glutamate receptor antagonists, such as NMDA receptor antagonists, such as MK-801 or Amitriptylline or Imipramine or Desipramine or Mirtazaprine or Venlafaxine. Other examples are substances which interact with nitric oxide, such as nitric oxide synthase (NOS) inhibitors, such as L-NMMA or L-NAME or L-NIO or L-NNA. According to a broader aspect of the invention tension-type headache is treated by administration of substances which are effective in preventing or decreasing pain in connection with tension-type headache, such as the substances mentioned above. An additional aspect of the invention relates to treatment of tension-type headache by administration of substances which substantially inhibit the activity of nitric oxide synthase (NOS), such as NOS inhibitors, such as L-NMMA or L-NAME or L-NIO or L-NNA.
    治疗紧张型头痛的方法是,与头痛有关的疼痛神经元传递相互作用,防止或减少二阶痛觉神经元的敏化。具体来说,治疗方法是通过施用有效量的物质来防止或减少中枢敏化。这类物质的重要例子是与谷氨酸神经递质相互作用的物质,如谷氨酸受体拮抗剂,如NMDA受体拮抗剂,如MK-801或阿米替林或丙咪嗪或地西普胺或米氮平或文拉法辛。其他例子包括与一氧化氮相互作用的物质,如一氧化氮合酶(NOS)抑制剂,如L-NMMA或L-NAME或L-NIO或L-NNA。根据本发明更广泛的一个方面,治疗紧张型头痛的方法是施用能有效预防或减轻紧张型头痛相关疼痛的物质,如上述物质。本发明的另一个方面涉及通过施用实质上抑制一氧化氮合酶(NOS)活性的物质,如NOS抑制剂,如L-NMMA或L-NAME或L-NIO或L-NNA,来治疗紧张型头痛。
