Leupeptin
Based on 68 publication(s) in Google Scholar
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.

In Vitro
Leupeptin (50-200 µM; 3.5 h) 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, with its mechanism associated with the inhibition of PTEN/PI3K/Akt/NF-κB/ERK1/2/p38 signaling pathway activation[1].
Leupeptin (50-200 µM; 48 h) reduces the Con-A (Concanavalin A) (HY-P2149)-induced proliferation index of mouse splenic lymphocytes and significantly decreases the Th1/IL-10 and Th2/IL-10 cytokine ratios, thereby modulating adaptive immune responses[1].

In Vivo
Leupeptin (40 mg/kg; i.p.; single dose; sacrificed 3 h post-injection) detects a 45% increase in macroautophagic flux in calorie-starved mouse liver and significant suppression of flux in refed mouse liver, with a 3-hour flux value of 53.94 ng/mg total protein in starved mice[3].
Leupeptin (40 mg/kg; i.p.; single dose; sacrificed 60 min or 180 min post-injection) detects a significant reduction in p62 flux (but not statistically significant reduction in LC3b-II flux) in beclin 1+/- mouse liver compared to wild-type littermates, with an 180-minute p62 flux value of 18 ng/mg total protein in heterozygous mice[3].

Result:Produced a dose-dependent increase in LC3b-II levels in mouse liver total extracts and lysosome-enriched (LE) fractions, with the 36 mg/kg dose inducing the strongest signal.
Led to time-dependent LC3b-II accumulation across multiple organs, with liver reaching 69.1 ng/mg total protein in LE fractions at 60 min, a flux of 42.1 ng/mg total protein, and spleen reaching 37.1 ng/mg total protein in LE fractions at 60 min, a flux of 11.0 ng/mg total protein.
Increased LC3a-II and p62 levels in liver LE fractions, but did not increase levels of GABARAP or GATE-16.
Induced a 6.88-fold increase in cross-sectional area of late autophagosome/lysosomal compartments in hepatocytes (from 0.36% to 2.50% of total cytoplasmic area; p = 0.013), with this increase correlating with LC3b-II levels in LE fractions (R2 = 0.7741).
Increased LC3b-II and LC3a-II content in dense, lysosome-enriched fractions of lung homogenates.
Stabilized LC3b-II and LC3a-II levels in liver LE fractions (but not cytosolic fractions) following cycloheximide-induced translational inhibition.
