InSolution SB 203580-Calbiochem

C₂₁H₁₆FN₃OS

377.43

A highly specific, cell-permeable inhibitor of p38 kinase (IC₅₀ = 34 nM in vitro, 600 nM in cells). Also known as reactivating kinase (RK) and CSBP (cytokine synthesis anti-inflammatory drug binding protein). Does not significantly inhibit JNK or p42 MAP kinase even at 100 µM. Inhibits IL-1 and TNF-α production from LPS-stimulated human monocytes and the human monocyte cell line THP-1 (IC₅₀ = 50-100 nM). SB 203580 has also been shown to be an effective inhibitor of inflammatory cytokine production in vivo in both mice and rats.

Cell permeable: yes
Target IC₅₀: 34 nM in vitro, 600 nM in cells against p38 MAPK; 50-100 nM Inhibiting IL-1 and TNF-α production from LPS-stimulated human monocytes and the human monocyte cell line THP-1; 0.2-1.0 µM inhibiting platelet aggregation by collagen
Product competes with ATP.
Reversible: yes

Toxicity: Irritant (B)

A 1 mg/ml solution of SB 203580 (Cat. No. 559389) in anhydrous DMSO.
