Scientific background

SB203580 is highly selective and cell permeable pyridinyl imidazole that inhibits the activity of MAP kinase homologs - p38 (stress-activated protein kinase II/HOG1) and p54 (stress-activated protein kinase I/c-Jun N-terminal kinase) with IC50 values of 50 and 500 nM for p38/SAPK2a and p38/SAPK2b respectively.1-6 SB203580 also inhibits the phosphorylation and activation of protein kinase B (PKB, also known as Akt) by inhibiting the PKB kinase, phosphoinositide-dependent protein kinase 1 (IC50 3-5 µM).7-9

Lead time: 1-2 Business Days

Need this compound in a format that drops straight into your assay? We can tailor formulation, chemistry, and documentation so your results stay consistent across runs and re-orders.

  • Format options: solid or pre-dissolved solution (choose solvent), target concentration, aliquots, light/moisture-protected packaging
  • Chemistry options: free base/acid vs salt forms, hydrate/solvate preference, stereoisomer control (single enantiomer or racemate), close analogs
  • Add-on labels & handles: D/¹³C/¹⁵N isotopes (LC-MS/internal standards), azide/alkyne or other functional handles for conjugation
  • QC & documentation: standard COA or enhanced analytical pack (HPLC/LC-MS/NMR), chiral purity, residual solvents, water content (KF), method-specific specs
  • Scale & continuity: mg to gram scale, bulk pricing, lot reservation, repeat-order continuity

To quote quickly, tell us: compound name + CAS/structure (SMILES or mol file), intended assay context, solvent preference, salt/stereochemistry requirements, purity/QC level, and the amount (mg–g).
