A method of detecting an activity of a COX-2 enzyme in a subject that includes obtaining a sample of the subject; detecting an amino acid eicosanoid metabolite in the sample, wherein the presence of the amino acid eicosanoid metabolite indicates the activity of the COX-2 enzyme of the subject. Preferably the amino acid eicosanoid metabolite is a PGH
2
-Gly or HETE-Gly metabolite. The metabolite may be detected based on metabolism of a COX-2-selective substrate. Preferably, the substrate is a lipoamino acid. More preferably, the lipoamino acid is selected from NAGly, N-arachidonyl-alanine, and &dgr;-arachidonyl aminobutuyic acid.
一种检测受试者体内 COX-2 酶活性的方法,包括获取受试者的样本;检测样本中的
氨基酸类二十碳烷代谢物,其中
氨基酸类二十碳烷代谢物的存在表明受试者体内 COX-2 酶的活性。
氨基酸类
二十烷代谢物最好是
PGH
2
-Gly 或 HETE-Gly 代谢物。代谢物可根据 COX-2 选择性底物的代谢情况进行检测。底物最好是脂
氨基酸。更优选的是,脂
氨基酸选自 NAGly、N-arachidonyl-alanine 和&dgr;-arachidonyl aminobutuyic acid。
