Chemical Structure
Leupeptin hydrochloride
- CAS No.: 39740-82-4
- Formula:C20H39ClN6O4
- Molecular Weight:463.01
InChIKey: OQQYPQNFLLAILR-FRKSIBALSA-N
SMILES: CC(C)C[C@H](NC(C)=O)C(N[C@@H](CC(C)C)C(N[C@H](C=O)CCCNC(N)=N)=O)=O.Cl
Biological Activity: Leupeptin hydrochloride is a broad-spectrum protease inhibitor. By inhibiting the activation of the PTEN/PI3K/Akt/NF-κB/ERK1/2/p38 signaling pathway, Leupeptin hydrochloride 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 hydrochloride inhibits blood coagulation and tumorigenesis in mouse skin. Leupeptin hydrochloride can be used in research on chronic inflammatory diseases and skin tumorigenesis[1][2][3].
