Biological Activity

Description Pepstatin A (Pepstatin) is a potent aspartic protease inhibitor, and also inhibits HIV replication. Pepstatin A is also an inhibitor of cathepsins D and cathepsins E. Pepstatin A inhibits autophagy by suppressing lysosomal proteases.
Targets
aspartic protease [1] cathepsins D [2] cathepsins E [2]
In vitro

Pepstatin A shows effective inhibition on aspartic proteinases such as pepsin, cathepsins D and E. In HIV-infected H9 cells, pepstatin A inhibits part of the intracellular processing of the HIV gag protein with no apparent toxicity on HIV-infected cells. [1]

Pepstatin A laos suppresses the differentiation of osteoclasts by blocking ERK signaling and the inhibition of NFATc1 expression. [2]
