    • The present invention provides a method for identifying a compound having muscarinic agonist activity that will lower intraocular pressure without causing miosis which comprises measuring the activity of the compound at the m.sub.3 and m.sub.5 muscarinic receptors and determining from the activity measurement a compound having at least twice the agonist activity at the m.sub.5 receptor as compared to the m.sub.3 receptor. Preferably, the method of measuring said muscarinic agonist activity comprises eliciting phosphoinositide hydrolysis in CHO-K1 cells stably expressing the m.sub.3 and m.sub.5 muscarinic receptor subtypes. The present invention also provides a method of lowering the intraocular pressure in a mammal which comprises administering to said mammal a compound that has been determined to have at least twice the agonist activity at the m.sub.5 receptor as compared to the m.sub.3 receptor.
    • 本发明提供了一种用于鉴定具有毒蕈碱激动剂活性的化合物的方法,其将降低眼内压而不引起瞳孔缩小,其包括测量化合物在m3和m5毒蕈碱受体的活性,并从活性测定确定具有至少两倍 与m3受体相比,m5受体的激动剂活性。 优选地,测量所述毒蕈碱激动剂活性的方法包括在稳定表达m3和m5毒蕈碱受体亚型的CHO-K1细胞中引发磷酸肌醇水解。 本发明还提供一种降低哺乳动物眼内压的方法,其包括向所述哺乳动物施用与m 3受体相比被确定具有m5受体的激动剂活性至少两倍的化合物。

    • The present invention provides a method of providing neuroprotection to a mammal comprising administering to said mammal suffering from or at risk of suffering a noxious action on its nerve cells an effective amount of a compound of formula I to inhibit or prevent nerve cell injury or death wherein the 2-imidazolin-2-ylamino group is in either the 5- or 6-position of the quinoxaline nucleus; x, y and z are in any of the remaining 5-, 6-, 7- or 8-positions and are selected from hydrogen, halogen, lower alkyl, lower alkoxy or trifluoromethyl; and R is an optional substituent in either the 2- or 3-position of the quinoxaline nucleus and may be hydrogen, lower alkyl or lower alkoxy, or pharmaceutically acceptable salts thereof and mixtures thereof. Such noxious action may result from ischemia, e.g. spinal ischemia.
    • 本发明提供了向哺乳动物提供神经保护作用的方法,包括对所述哺乳动物患有或有风险对其神经细胞发生有害作用的有效量的式I化合物以抑制或预防神经细胞损伤或死亡,其中 2-咪唑啉-2-基氨基在喹喔啉核的5-或6-位; x,y和z在剩余的5-,6-,7-或8-位中的任一个中,并且选自氢,卤素,低级烷基,低级烷氧基或三氟甲基; 并且R是喹喔啉核的2-或3-位任选的取代基,并且可以是氢,低级烷基或低级烷氧基,或其药学上可接受的盐及其混合物。 这种有害作用可能是由局部缺血引起的。 脊髓缺血。
