compound introduction
N-(p-Tosyl)-GPR-pNA acetate是靶向合成肽 Hirunorm IV 和 Hirunorm V 的显色底物，可用于检测两种肽的解离常数 (KI)。Hirunorm IV 和 Hirunorm V 是酰胺分解凝血酶活性的可逆抑制剂。通过改变显色底物 N-(p-Tosyl)-GPR-pNA acetate 固定浓度下的肽浓度，测定的解离常数分别为 0.134 nM (Hirunorm IV) 和 0.245 nM (Hirunorm V)。 N-(p-Tosyl)-GPR-pNA acetate is a chromogenic substrate targeting the synthetic peptides Hirunorm IV and Hirunorm V and can be used to detect the dissociation constants (KI) of both peptides . Hirunorm IV and Hirunorm V are reversible inhibitors of amidolytic thrombin activity. By varying the peptide concentration at a fixed concentration of the chromogenic substrate N-(p-Tosyl)-GPR-pNA acetate, the dissociation constants determined were 0.134 nM (Hirunorm IV) and 0.245 nM (Hirunorm V) .
