Adefovir dipivoxil

Adefovir dipivoxil is an orally active adenosine analog and Adefovir prodrug. Adefovir dipivoxil inhibits DNA synthesis, activates the ATR signaling pathway, and disrupts the KCTD12-CDK1 interaction. Adefovir dipivoxil has antiviral activity against PRV, HBV, and orthopoxviruses. Adefovir dipivoxil has inhibitory effects on both lamivudine-resistant and wild-type strains. Adefovir dipivoxil has antitumor activity against lung and colon cancer^{[1][2][3][4][5][6][7][8][9][10][11]}. In Vitro:Adefovir dipivoxil (0.03-30 μM; 6 days) significantly inhibits the proliferation of H1975, A549 and PC9 cells, with more pronounced inhibition when co-treated with VE822^[1].
Adefovir dipivoxil (1 μM; 3 days) exhibits increased basolateral-to-apical transport and an elevated efflux ratio in Caco-2 cells treated with 1,25(OH)₂D₃^[2].
Adefovir dipivoxil (24 h) can effectively inhibit PRV proliferation in PK-15 cells, with an IC₅₀ of 92.39 nM^[4].
Adefovir dipivoxil (1-10 μM) sensitizes colon cancer cells (HCT116-CDK1 and HT29-CDK1 cells) to Vemurafenib (HY-12057) by disrupting KCTD12-CDK1 interaction^[5].
In Vivo:Adefovir dipivoxil (5 mg/kg; i.p.; once a day, 5 days) can potently protect mice against lethal PRV infection, as shown by reduced pathological lesions, lower viral particles in major organs, and increased survival rate^[4].
Adefovir dipivoxil (10-50 mg/kg; p.o.; every other day) inhibits the growth of colon cancer cell-derived tumor xenografts in BALB/c nude mice^[5].
Adefovir dipivoxil (100 mg/kg/day; p.o.; twice daily; 10 days) reduces viral load in the liver and serum in transgenic mice expressing hepatitis B virus (HBV)^[6].
Adefovir dipivoxil (250 mg prodrug per dog for suspension; p.o.; single dose) shows oral bioavailability of 35.0% (suspension) in beagle dogs^[7].
Adefovir dipivoxil (30 mg/kg; every other day; 21 days) causes a marked reduction of duck HBV (DHBV) DNA in serum in congenitally HBV-infected ducklings^[8].
