Hck-IN-1 (compound B9) shows weak activity against other Src-family members in vitro, with IC50 values >20 μM for c-Src, Lck and Lyn.
B9 (1 μM; 8 days) completely inhibits Nef-dependent SFK activation at a concentration of 1.0 μM.
Hck-IN-1 (0.1, 0.3, 1, 3 μM) also inhibits Nef-mediated enhancement of HIV-1 infectivity in a concentration-dependent manner in the reporter cell line, TZM-bl.
Hck-IN-1 inhibits the replication of all eleven HIV-1 Nef chimeras with IC50 values of ~ 300 nM in CEM-T4 cells, demonstrating that the compound is broadly active against HIV replication supported by a wide range of HIV-1 Nef proteins.
