CHEBI:608828 ·resolve ·ANTIVIRAL ·EXACT SEEDED

A synthetic 36-amino acid peptide consisting of N-acetyltyrosyl, threonyl, seryl, leucyl, isoleucyl, histidyl, seryl, leucyl, isoleucyl, α-glutamyl, α-glutamyl, seryl, glutaminyl, asparaginyl, glutaminyl, glutaminyl, α-glutamyl, lysyl, asparaginyl, α-glutamyl, α-glutamyl, α-glutamyl, leucyl, leucyl, α-glutamyl, leucyl, α-aspartyl, lysyl, tryptophyl, alanyl, seryl, leucyl, tryptophyl, asparaginyl, tryptophyl, and phenylalaninamide residues joined in sequence. An HIV fusion inhibitor, it was the first of a novel class of antiretroviral drugs used in combination therapy for the treatment of HIV-1 infection. It interferes with entry of HIV into cells by binding to the gp41 sub-unit of the viral envelope glycoprotein, so inhibiting fusion of viral and cellular membranes. — ChEBI

Mechanism summary

Mode of action: VIRAL_ENTRY_INHIBITION host shared target — Assigned from ChEBI role CHEBI:59886 (HIV fusion inhibitor). ChEBI asserts the role on the compound. The target it names is one the host has too, so the mechanism is true but is not evidence of selectivity — see mode_of_action_target_scope. Not a curator's mechanistic review.
