| Bioactivity | L-689502 is a potent inhibitor of HIV-l protease with an IC50 of 1 nM. | 
| Target | IC50: 1 nM (HIV-l protease) | 
| Invitro | Both L694746 and L-689502 inhibit HIV-l ptotease activity in a concentration-dependent manner. Pepstatin is much less potent than either compound exhibiting an IC50 of 2 μM. L694746 is as potent as L-689502 in inhibiting the HIV-l protease despite being structurally different from L-689502[1]. |
