Description

SB203580 is a selective ATP-competitive p38 MAPK inhibitor with IC50s of 50 nM and 500 nM for SAPK2a/p38 and SAPK2b/p38β2, respectively. SB203580 inhibits LCK, GSK3β and PKBα with IC50s of 100-500-fold higher than that for SAPK2a/p38. SB203580 does not disrupt JNK activity and is an autophagy and mitophagy activator. SB203580 has been shown to enhance clonal growth of skin epithelial progenitor cells and to stimulate neural stem cell (NSC) proliferation. Additionally, SB203580 has also demonstrated significant inhibition of the proliferation of HNSCC cells both in vitro and in vivo.

Features
  • Enhances the growth of mouse embryonic stem (ES) cells (Qi et al.)
  • Promotes long-term maintenance of human naïve pluripotent stem cells (Gafni et al.)
  • Promotes proliferation of human endothelial progenitor cells (Seeger et al.)
  • Enhances differentiation of cardiomyocytes from human ES cells (Gaur et al., Graichen et al.)
