a

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.

b

ARV experienced (Exp.) or naïve.

c

Isolates designated in boldface had both genotypic and phenotypic PI resistance. Data are shown in Table 2.

d

The last 7 amino acids of the Gag-capsid protein sequences are shown.

e

The complete amino acid sequences of Gag-SP1 are shown (14 residues).

f

The letters in parentheses represent the wild-type sequence.

g

Del, deletion.

h

A complex S373P/T/Q/K amino acid mixture was found at that site.

i

A complex A374A/G/T/S amino acid mixture was found at that site.

j

—, same as wild type.
