Description

Leupeptin is a broad-spectrum, membrane-permeable protease inhibitor. Leupeptin potently inhibits serine, cysteine and threonine proteases. Leupeptin inhibits Mpro (the main protease of SARS-CoV-2) and also has anti-inflammatory activity[1][2][3].

IC50 & Target

Cathepsin B, Cathepsin H, Cathepsin L, Ser/Thr Protease, Mpro[1][2][3].
In Vitro

Leupeptin (0.06-200 µM; 72 h) significantly decreases copy numbers of SARS-CoV-2 viral RNA (vRNA) in Vero cells[1]
Leupeptin inhibits RNA levels of SARS-CoV-2 in Vero cells, with an EC50 value of 42.34 µM[1].
Leupeptin has some inhibitory activity against Mpro, with an IC50 value of 127.2 µM[1].
Leupeptin againsts human coronavirus strain 229E with an IC50 value of 0.4 µg/mL (about 1 µM)[1].

In Vivo

Leupeptin (0, 9, 18, 36 mg/kg; i.p.; single) is well tolerated by the animals and produces a strong, dose-dependent increase in LC3b-II in both the total tissue extracts and the lysosome and autophagosome-enriched pellet fraction[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
