Overview

Adefovir Dipivoxil works by blocking reverse transcriptase, an enzyme that is crucial for the hepatitis B virus (HBV) to reproduce in the body. Target: NRTIs; HBV Adefovir Dipivoxil works by blocking reverse transcriptase, an enzyme that is crucial for the hepatitis B virus (HBV) to reproduce in the body. Adefovir Dipivoxil is used for treatment of hepatitis B and herpes simplex virus infection [1-3]. Adefovir Dipivoxil is approved for the treatment of chronic hepatitis B in adults with evidence of active viral replication and either evidence of persistent elevations in serum aminotransferases (primarily ALT) or histologically active disease. Adefovir Dipivoxil is a failed treatment for HIV[3, 4].
Catalyst employed in the Sharpless Asymmetric Dihyroxylation of (E,E)- or (E,Z)-1,3-dienoates.¹ Also used in the preparation of ?-hydroxy-γ-lactones from ?,γ-unsaturated esters.²

Product Introduction:

Adefovir dipivoxil, an adenosine analogue, is an oral proagent of the nucleoside reverse transcriptase inhibitor Adefovir. Adefovir dipivoxil inhibits both the wild type and HBV Lamivudine-resistant strains. Adefovir dipivoxil shows anti-orthopoxvirus activity.

Note

Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
