Leupeptin hemisulfate is a membrane-permeable thiol protease inhibitor that inhibits Cathepsin B, Cathepsin H and Cathepsin L, and also impairs amphisome-lysosome fusion[1]. Leupeptin hemisulfate also exhibits anti-inflammatory effect[2].

IC50 & Target
|
Cathepsin[1]

体内研究
(In Vivo)
|
Leupeptin (0-36 mg/kg; intraperitoneal injection; for 4 hours; C57BL/6NCrl male mice) 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]..
Animal Model:
|
C57BL/6NCrl male mice (6-8 weeks old, 20-25 g)[2]
|
Dosage:
|
0 mg/kg, 9 mg/kg, 18 mg/kg, 36 mg/kg
|
Administration:
|
Intraperitoneal injection; for 4 hours
|
Result:
|
Promoted the accumulation of LC3b-II in mouse liver.
