Table 1: Antiviral activities of M522 and M532 against drug-resistant, laboratory strains of HIV-1 in H9 cells. aAnti-HIV activity (IC50), 50% inhibitory concentration or concentration of each inhibitor required to inhibit viral replication by 50 % and calculated as (µM) ± SD. Results were obtained from three independent experiments performed in duplicate.
