porcine pancreatic elastase

Elastase from porcine pancreas is a serine protease derived from the porcine pancreas, consisting of 240 amino acid residues. It has the ability to hydrolyze proteins and peptides, can induce emphysema in hamsters, and is commonly used to establish animal models of chronic obstructive pulmonary disease (COPD).

FK706 is a slow-binding and competitive human neutrophil elastase inhibitor (IC50: 83 nM; Ki: 4.2 nM). FK706 also inhibits mouse neutrophil elastase and porcine pancreatic elastase (IC50s: 22 nM and 100 nM, respectively). FK706 has an anti-inflammatory ef

ZD-0892 is a selective and potent inhibitor of neutrophil elastase, targeting human neutrophil elastase and porcine pancreatic elastase with Kis of 6.7 nM and 200 nM, respectively.

Suc-AAP-Abu-pNA is a specific substrate for pancreatic elastase (Km = 100 μM; Kcat/Km = 35,300 s-1 M-1 for rat pancreatic elastase; Km = 30 μM; Kcat/Km = 351,000 s- 1 M-1 for porcine pancreatic elastase).

Eglin c (60-63) is a sequence of a peptide that has been studied for its inhibitory activity towards human leukocyte elastase, cathepsin G, porcine pancreatic elastase and alpha-chymotrypsin.

Tutuilamide A, a potent inhibitor of porcine pancreatic elastase (PPE) with an IC50 of 1.2 nM, also effectively inhibits human neutrophil elastase (HNE; IC50=0.73 nM) and kallikrein 7 (KLK7; IC50=5.0 nM) [1].

Lipid TG4C, an ionizable cationic glycerolipid (pKa = 6.71), has been utilized for creating lipid nanoparticles (LNPs) designed to deliver mRNA in vivo. In mice, these LNPs containing lipid TG4C and mRNA encoding human erythropoietin (EPO) result in increased serum EPO levels. Additionally, inhalation of LNPs with lipid TG4C carrying mRNA for human hepatocyte growth factor (HGF) decreases levels of Il-1β, Il-6, and Tnf-α in bronchoalveolar lavage fluid (BALF) in a mouse model of pulmonary emphysema induced by porcine pancreatic elastase.
