- The concentration of compounds that inhibit HIV gene expression by 50% (IC50) and the concentration that decreases cellular toxicity to 50% (CC50) relative to DMSO-treated cells are listed. Compound toxicity was measured by either a cellular metabolism assay (XTT). trypan blue exclusion, fluorescence-activated cell sorting (FACS) or Guava ViaCount assay. For the CEM-GXR cells, the CC50 was based on the compound toxicity tn cells infected with a Clade B HIV-1 strain, while uninfected calls were used for the ViaCount assay.
