Chemical Structure
Leupeptin
- CAS No.: 55123-66-5
- Formula:C20H38N6O4
- Molecular Weight:426.55
IUPAC Name: (S)-2-acetamido-N-((S)-1-(((S)-5-guanidino-1-oxopentan-2-yl)amino)-4-methyl-1-oxopentan-2-yl)-4-methylpentanamide
InChIKey: GDBQQVLCIARPGH-ULQDDVLXSA-N
SMILES: O=C[C@@H](NC([C@@H](NC([C@@H](NC(C)=O)CC(C)C)=O)CC(C)C)=O)CCCNC(N)=N
Biological Activity: Leupeptin is a broad-spectrum protease inhibitor. By inhibiting the activation of the PTEN/PI3K/Akt/NF-κB/ERK1/2/p38 signaling pathway, Leupeptin significantly reduces LPS-induced NO and ROS production, mitochondrial membrane potential hyperpolarization, phagocytic activity, pro-inflammatory cytokine release, and M1 polarization in mouse peritoneal macrophages, and reverses autophagic flux impairment. It also decreases Concanavalin A (HY-P2149)-induced proliferation index of mouse splenic lymphocytes and the Th1/IL-10 and Th2/IL-10 cytokine ratios, thereby modulating innate and adaptive immune responses. Leupeptin inhibits blood coagulation and tumorigenesis in mouse skin. Leupeptin can be used in research on chronic inflammatory diseases and skin tumorigenesis[1][2][3][4].
