PR 39 (PORCINE) Chemical Properties,Usage,Production
Uses
PR-39, a natural proline- and arginine-rich antibacterial peptide, is a noncompetitive, reversible and allosteric proteasome inhibitor. PR-39 reversibly binds to the α7 subunit of the proteasome and blocks degradation of NF-κB inhibitor IκBα by the ubiquitin-proteasome pathway. PR-39 stimulates angiogenesis, inhibits inflammatory responses and significant reduces myocardial infarct size in mice[1][2].
Definition
ChEBI: PR-39 is a 39 amino acid porcine cathelicidin that is rich in proline and arginine residues. It plays a pivotal role in the innate immune defence of the pig against infections and exhibits antimicrobial and immunomodulatory activities. It has a role as an antibacterial agent, an apoptosis inhibitor, an anti-inflammatory agent, a mammalian metabolite, an antifungal agent and an immunomodulator.
in vivo
PR-39 (10 mg/kg, intravenously; 1 hour before Caerulein of 50μg/kg, ip) blocks IκBα degradation and NF-κB-dependent transcription in the mouse pancreas after induction of acute pancreatitis[2].
PR-39 (1 μg/kg/day; 7-day intraperitoneal infusion) demonstrates significantly small infarct in C57BL/6 mice[2].
