SB 220025 trihydrochloride may be used in p38-mediated cell signaling studies.

SB 220025 is a potent, specific inhibitor of human p38 MAP kinase (IC₅₀ = 60 nM).

SB 220025 is a potent, specific inhibitor of human p38 mitogen-activated protein (MAP) kinase, with an IC₅₀ value of 60 nM and 50- to 1000-fold selectivity. SB 220025 reduces inflammatory cytokine production and inhibits angiogenesis. SB 220025 reduced the lipopolysaccharide-induced production of TNF at an ED₅₀ value of 7.5 mg/kg. At 30 mg/kg, SB 220025 reduced the expression of TNF and inhibited angiogenesis by ~40%. In a further study, the effects of p38/CSBP MAP kinase inhibition in angiogenesis-dependent chronic inflammatory disease was tested in murine collagen-induced arthritis and SB 220025 was able to prevent the progression of established arthritis.
