Basic description
|
36 residue synthetic peptide that inhibits HIV-1 fusion with CD4 cells. N-terminal acetylated, C-terminal amide. Enfuvirtide is the first in this class to reach market approval. Fusion inhibitors block the last step in the three-step viral entry process consisting of attachment, co-receptor binding and fusion, thereby preventing viral capsid entry into the host cell. Enfuvirtide has a unique mechanism of action and viral target specificity, and in clinical trials has been shown to exhibit both efficacy and low toxicity. Enfuvirtide is a peptide mimetic of an essential region within viral envelope glycoprotein gp41 that functions by blocking gp41 structural rearrangements at a transitional pre-fusion conformation.
