Entecavir-d2 is intended for use as an internal standard for the quantification of entecavir by GC- or LC-MS. Entecavir is an antiviral nucleoside analog of 2'-deoxyguanosine and inhibitor of hepatitis B virus (HBV) reverse transcriptase (IC50 = 0.5 nM).1,2 It undergoes phosphorylation by cellular kinases to its active form, entecavir triphosphate.2,3 Entecavir reduces virion DNA in the culture supernatant of HepG2 2.2.15 cells infected with hepatitis B virus (HBV; EC50 = 3.75 nM).1 It reduces serum and hepatic levels of viral DNA in a duckling model of HBV infection when administered at a dose of 1 mg/kg.4 Formulations containing entecavir have been used in the treatment of chronic HBV infection.

计算结果:
工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
