Fold change (FC) in the bevirimat EC50 compared to the wild-type EC50 of 34 nM against HIV-1 LAI. The statistical significance of the fold changes in the EC50s compared to the wild-type EC50 is expressed as P < 0.01 (**) and P < 0.05 (*). The results are the averages of at least three independent experiments.
ARV experienced (Exp.) or naïve.
Isolates designated in boldface had both genotypic and phenotypic PI resistance. Data are shown in Table 2.
The last 7 amino acids of the Gag-capsid protein sequences are shown.
The complete amino acid sequences of Gag-SP1 are shown (14 residues).
The letters in parentheses represent the wild-type sequence.
Del, deletion.
A complex S373P/T/Q/K amino acid mixture was found at that site.
A complex A374A/G/T/S amino acid mixture was found at that site.
—, same as wild type.
