Leupeptin hemisulfate (Synonyms: 亮肽素)
Leupeptin hemisulfate 是一種可透過膜的巰基蛋白酶抑制劑，可抑制 Cathepsin B, Cathepsin H 和 Cathepsin L，并損害兩性溶酶體的融合。Leupeptin hemisulfate 也具有抗yan作用。
生物活性
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]
體內研究(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
| Animal Model: | C57BL/6NCrl male mice (6-8 weeks old, 20-25 g)[1] |
| 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. |
