Descripción general

CHIR99021 is an aminopyrimidine derivative. CHIR99021 promotes self-renewal potential of embryonic stem cells (ESCs) of mice by inhibiting glycogen synthase kinase-3 (GSK-3) activity and potentiates the upregulation of β-catenin and c-Myc functions. CHIR99021 promotes self-renewal of ESCs by modulating transforming growth factor β (TGF-β), Notch and mitogen-activated protein kinases (MAPK) signaling pathways. CHIR99021 is an agonist of wingless/integrated (wnt) signalling, upregulates cyclinA expression and promotes cell proliferation in non-small-cell lung cancer (NSCLC) cell lines.


CHIR99021 has been used:
  • in cocktail with small molecules to convert human lung fibroblast cells into neurons
  • as a culture medium supplement in potassium supplemented simplex optimization medium (KSOM) for the culture of blastocysts
  • for chronic inhibition of GSK-3 to investigate its role in corticogenesis

Acciones bioquímicas o fisiológicas

CHIR99021 is a very potent inhibitor of Glycogen synthase kinase 3 (GSK3, IC50 values for GSK3α and GSK3β = 10 and 6.7 nM, respectively). There is no cross-reactivity against CDKs. CHIR99201 potentiates self-renewal of human and mouse embryonic stem cells, and enhances reprogramming of somatic cells into stem cells.

Naive Pluripotent Stem Cell Culture in an Inhibitor Based 2i/LIF Containing Serum-Free and Feeder-Free Stem Cell Media

Naive pluripotent stem cells are located within the epiblast of mature blastocysts. These primitive “ground-state” cells may be cultured in vitro using specialized media and small molecule inhibitors.
