These peptides were synthesized with an Fmoc strategy using Rink Amide Resin. Their N- and C-termini were acetylated and amidated, respectively. All the peptides were purified by reverse phase high performance liquid chromatography to >95% homogeneity. The molecular weight of the peptides was confirmed by MALDI-TOF-MS (Autoflex III, Bruker Daltonics).

    • 4 at the final concentration of 2 mg/mL, followed by addition of 3 equiv TCEP and adjustment of the pH to 7.0. The reaction was monitored by HPLC. The cyclic peptides were then purified by reverse phase HPLC to >95% homogeneity. The molecular weight of the peptides was confirmed by MALDI-TOF-MS (Autoflex III, Bruker Daltonics).

For determining the inhibitory activity of the peptides on infection by a pseudovirus expressing the envelop protein gp160 of the HIV-1 R5 virus SF162, U87-CCR5 cells (1 × 104/well) were seeded in 96-well plates and grown overnight. A peptide at indicated concentration was incubated with pseudotyped particles For construction and expression of a pseudovirus expressing the envelop protein gp160 of the HIV-1 R5 virus SF162, (1 ng p24/well) for 30 min at 37 °C. Subsequently, the virus-compound mixture was transferred to the cells and incubated for an additional 48 h. Cells were washed with PBS and lysed with the lysing reagent included in the luciferase kit (Promega, Madison, WI). Aliquots of cell lysates were transferred to luminometer plates, followed by the addition of luciferase substrate. The luciferase activity was measured in a microplate luminometer (Genios Pro, Tecan).
