What is Adefovir?

Adefovir, with the CAS number 106941-25-7, is a potent antiviral medication classified as an acyclic phosphonate nucleotide analog of dAMP. It is commercially known by its trade names Preveon and Hepsera. This compound is primarily used for the treatment of chronic hepatitis B virus (HBV) infections.

Kémiai tulajdonságok

• Molekuláris képlet: C₈H₁₂N₅O₄P
• Molekulatömeg: 273.19 g/mol
• CAS-szám: 106941-25-7
• Szinonimák: GS-0393, GS-393, PMEA, 9-(2-phosphonylmethoxyethyl)adenine

A hatásmechanizmus

Adefovir works as a DNA polymerase inhibitor. It exerts its antiviral activity by:

1. Inhibiting reverse transcriptase – Blocks HIV-1 replication
2. Inhibiting polymerase activity – Prevents HBV DNA replication
3. Chain termination – Incorporates into viral DNA, causing premature termination

The compound is converted to its active diphosphate form inside cells, which then competitively inhibits viral DNA polymerase.
