maturation inhibitor
maturation inhibitor
An antiretroviral agent that inhibits viral replication by disrupting late Gag processing, which is required for the structural rearrangement of viral maturation, a key step in the maturation of viral particles into mature, infectious virions.Maturation inhibitors (e.g., PA-457) prevent virus maturation by interrupting the conversion of the capsid precursor (p25) to a mature capsid protein (p24), resulting in the formation of defective, noninfectious virus particles.
