代谢
阿卡鲁替尼主要由CYP3A酶代谢。ACP-5862被确认为血浆中的主要活性代谢物,其几何平均暴露(AUC)大约是阿卡鲁替尼的2-3倍。在抑制BTK方面,ACP-5862的效力比阿卡鲁替尼低大约50%。
Acalabrutinib is mainly metabolized by CYP3A enzymes. ACP-5862 is identified to be the major active metabolite in plasma with a geometric mean exposure (AUC) that is about 2-3 times greater than the exposure of acalabrutinib. ACP-5862 is about 50% less potent than acalabrutinib in regards to the inhibition of BTK.
