Leupeptin hemisulfate (Standard)
Leupeptin hemisulfate (Standard) is the analytical standard of Leupeptin hemisulfate (HY-18234A). This product is intended for research and analytical applications. Leupeptin hemisulfate is a broad-spectrum protease inhibitor. Leupeptin hemisulfate inhibits serine, cysteine and threonine proteases, and regulates autophagy. Leupeptin hemisulfate reduces the expression levels of LC3B, iNOS, Cox-2, Beclin-1 and the level of endopeptidases; increases the levels of p62, Arg 1, Msr 1 and Mrc−1; and blocks the upregulation of p-PTEN, p-NF-κB, p-PI3K, p-Akt, p-p38 and ERK1/2. Leupeptin hemisulfate inhibits NO, ROS, proinflammatory cytokines, the IFN-γ/IL-10 ratio, phagolysosome fusion, mammalian lysosomal hydrolase activity and SARS-CoV-2 replication; and reverses impaired autophagic flux. Leupeptin hemisulfate is applicable to research related to chronic inflammatory diseases, edema, skin tumorigenesis, COVID-19 and respiratory infections.
