Adefovir-d4 is intended for use as an internal standard for the quantification of adefovir by GC- or LC-MS. Adefovir is an active metabolite of the antiviral nucleoside analog adefovir dipivoxil .1 Adefovir is formed from adefovir dipivoxil by gastrointestinal carboxylesterase 2 (CES2).2 It inhibits cytopathogenicity induced by herpes simplex virus 1 (HSV-1) and HSV-2 (EC50 = 7 μg/ml for both in E6SM cells), HIV-1 and HIV-2 (EC50s = 1.8 and 2.5 μg/ml, respectively, in CEM cells), and varicella zoster virus (VZV; EC50 = 10 μg/ml in human embryonic lung fibroblasts).3 Adefovir (50 mg/kg, p.o.) reduces increases in lymph node viral DNA and serum IgG levels in a mouse model of AIDS induced by infection with the retroviral complex LP-BM5.4 It also inhibits tumor growth induced by Moloney sarcoma virus (MSV) infection in mice at the same dose.5
