生物活性

Enfuvirtide (T20;DP178) is an anti-HIV-1 fusion inhibitor peptide.

IC50 & Target

HIV fusion[1]
体外研究
(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].

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].
