Disclosed is a method of measuring affinity of a test compound for a receptor protein. The method includes the steps of providing a receptor-ligand complex comprising a receptor and a quinoxaline derivative ligand bound thereto; then contacting the receptor-ligand complex with a test compound, thereby yielding a receptor-test compound complex and an amount of free quinoxaline derivative; and then measuring the amount of the free quinoxaline derivative generated as a result of the previous step. In this fashion, the affinity of the test compound for the receptor can be determined.
本发明公开了一种测量试验化合物与受体蛋白亲和力的方法。该方法包括以下步骤:提供一个包括受体和一个
喹喔啉衍
生物配体结合在一起的受体-
配体复合物;然后将受体-
配体复合物与试验化合物接触,从而产生受体-试验化合物复合物和一定量的游离
喹喔啉衍
生物;然后测量由于前一步骤而产生的游离
喹喔啉衍
生物的数量。通过这种方法,可以确定试验化合物与受体的亲和力。
