| Description: |
Gabexate Mesylate is a Factor X inhibitor.Gabexate mesylate is a non-antigenic synthetic inhibitor of trypsin-like serine proteinases that is therapeutically used in the treatment of pancreatitis and disseminated intravascular coagulation and as a regional anticoagulant for hemodialysis. Values of the inhibition constant (K(i)) for gabexate mesylate binding to human and bovine tryptase were 3.4 x 10(-9) M and 1.8 x 10(-7) M (at pH 7.4 and 37.0 degrees ), respectively. Gabexate mesylate inhibited the fibrinogenolytic activity of human tryptase. Gabexate Mesylate decreased the TNFalpha production of LPS-stimulated monocytes as shown by the inhibition of mRNA expression and increased the IL-10 production of LPS-stimulated monocytes. Gabexate Mesylate also suppressed the NFkappaB activity of LPS-stimulated monocytes. Inhibitory effect of Gabexate Mesylate on the TNFalpha production of activated human monocytes is mediated by the suppression of NFkappaB activation. Gabexate mesylate inhibits competitively constitutive and inducible NO synthase (cNOS and iNOS, respectively), with Kivalues of 1.0×10?4M and 5.0×10?3M, respectively, at pH 7.4 and 37.0°C. gabexate mesylate increases iNOS mRNA expression in rat C6 glioma cells, as induced byE. colilipopolysaccharide plus interferon-γ. Gabexate mesylate inhibits dose-dependently nitrite production (i.e. NO release) in rat C6 glioma cells, as induced byE. colilipopolysaccharide plus interferon-γ. |
