Treatment of oesophageal carcinoma

5 Pharmacology and Biochemistry

5.1 MeSH Pharmacological Classification

Protease Inhibitors

Compounds which inhibit or antagonize biosynthesis or actions of proteases (ENDOPEPTIDASES). (See all compounds classified as Protease Inhibitors.)

5.2 Mechanism of Action

Elafin is able to abrogate lipopolysaccharide-induced production of monocyte chemotactic protein 1 in monocytes by inhibiting AP-1 and NFkappaB activation. Due to its selective expression at mucosal surfaces as well as in alveolar macrophages, monocytes and neutrophils, the ability of Elafin to inhibit the lipopolysaccharide signaling pathway may be important in disease states such as cystic fibrosis, pneumonia, and acute respiratory distress syndrome. The inhibition of two key inflammatory pathways confirms the importance of Elafin as a mediator of the innate immune response.
