代谢
布吉替尼通过CYP2C8(72.4%)和CYP3A4(27.6%)在人类肝微粒体和肝细胞中代谢。生成的两个主要代谢物是N-去甲基形式和半胱氨酸结合形式。口服放射性标记的布吉替尼显示,未改变形式的系统性存在为91.5%,主要代谢物AP26123为3.5%。AP26123的AUC小于布吉替尼AUC的10%,并表现出3倍的抑制效果降低。
Brigatinib is metabolized by CYP2C8 (72.4%) and CYP3A4 (27.6%) in human liver microsomes and hepatocytes. The two major metabolites generated are the N-demethylated form and the cysteine conjugated form. Oral administration of radiolabelled brigatinib showed the systemic presence of 91.5% in the unchanged form and 3.5% of the primary metabolite AP26123. The AUC of AP26123 is less than 10% of the AUC of brigatinib and presented an inhibitory effect 3 fold lower.
