Description Enfuvirtide is an anti-HIV-1 fusion inhibitor peptide. Sequence: Ac-Tyr-Thr-Ser-Leu-Ile-His-Ser-Leu-Ile-Glu-Glu-Ser-Gln-Asn-Gln-Gln-Glu-Lys-Asn-Glu-Gln-Glu-Leu-Leu-Glu-Leu-Asp-Lys-Trp-Ala-Ser-Leu-Trp-Asn-Trp-Phe-NH2.

Target HIV fusion[1]
In Vitro A cell-cell fusion assay reveals that the effective concentration for achieving 50% inhibition (IC50) of Enfuvirtide is 23 ± 6 nM[2]. IFN-λs (1, 2, or 3) or the antiretrovirals (AZT, Efavirenz, Indinavir, and Enfuvirtide) significantly inhibita the expression of HIV p24 antigen and Gag gene in macrophages. IFN-λs (1, 2, or 3) also enhanced the anti-HIV (Bal) effect of AZT, Efavirenz, Indinavir, and Enfuvirtide[3].
In Vivo Enfuvirtide has a T1/2 of 3.8 h[2].

10 mM 0.0223 mL 0.1113 mL 0.2226 mL
Animal Admin For infection with the resistant HIV strains, 7-day-cultured macrophages (105 cells/well in 96-well plates) are incubated with or without IFN-λ1, λ2, or λ3 (100 ng/mL each) and/or anti-HIV drugs: Azidothymidine (AZT) 10 pM; Efavirenz 100 pM; Indinavir 10-3 pM, and Enfuvirtide 10 nM for 24 h. Cells are then infected with different strains of HIV (6 ng p24/well) for 2 h. After washed three times with plain DMEM, cells are cultured with fresh 10% DMEM containing IFN-λs and/or antiretroviral drugs. For HIV Bal infection, culture supernatant is harvested at day 8 post infection for RT and p24 assays. Infected and untreated cells served as controls. HIV Gag gene expression in infected cells is also examined at day 8 post infection. For anti-HIV drug-resistant virus (A012 G691-6 or TC49) infection, culture supernatant is harvested for HIV p24 protein by ELISA at days 3, 5, 7, and 10 postinfection. The cell cultures are replaced with the fresh media supplemented with IFN-λ1, λ2, or λ3 and/or the antiretrovirals every 2–3 days. The culture supernatant collected at day 10 postinfection is also subjected to RT assay[3].

 Antimicrobial peptides are produced by plants and most organisms throughout the animal kingdom including humans. Antimicrobial peptides protect against a broad range of infectious agents, as bacteria, fungi, and viruses. The amphibian skin is an especially rich source of antimicrobial peptides. See also the product families: Hepcidins LL-37 and Fragments Tuftsin and Analogs (subfamily).


Enfuvirtide is a synthetic peptide derived from a naturally occurring amino acid sequence in the HR2 domain of GP41. By simulating the activity of the HR2 domain and competitively binding the HR1 domain of GP41, it prevents the interaction between HR1 and HR2 and changes in gp41 configuration, thus preventing the fusion of virus and host cells. Similar to most peptide drugs, the likelihood of metabolic drug interactions with enfveitide is low.
