L-689502 is a potent inhibitor of HIV-l protease with an IC50 of 1 nM.

IC50 & Target

IC50: 1 nM (HIV-l protease)[1]

In Vitro

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].

Cell Assay

G689502 (3.3 pmoles in 1 mL of 100% DMSO) is added to cultures that have been growing for 48 hr. The final substrate and DMSO concentrations during the fermentation period are 65 pM and 2%, respectively. The fermentations containing L-689502 are carried out for an additional 72-96 hr prior to be harvested.The whole broth is sequenthdly extracted with methanol (0.5 vol) and acetone (0.5 vol). The supematant containing the derivatives of L-689502 is separated from the mycelia by filtration[1].
