Application

Kenpaullone has been used:
  • as a glycogen synthase kinase 3 (GSK3)/ cyclin-dependent kinase (CDK) inhibitor to study its effects on human neural progenitor cell lines
  • as an inhibitor of Krupple-like factor 4 (KLF4) in Gs-coupled designer GPCR (Gs DREADD= GsD) Agouti-related peptide (GsD-AgRP) mice
  • as a GSK3/CDK inhibitor to study its effects on the sea urchin embryo development

Biochem/physiol Actions

Kenpaullone is also an inhibitor of glycogen synthase kinase 3β (GSK3β). It also inhibits cyclin-dependent kinase 1 (CDK1/cyclin B), CDK2/cyclin A, CDK2/cyclin E, and CDK5/p25, majorly by competitive inhibition of adenosine triphosphate (ATP) binding.

Agouti-related peptide (AgRP) neurons of the hypothalamus play a key role in regulating food intake and body weight, by releasing three different orexigenic molecules: AgRP; GABA; and neuropeptide Y. AgRP neurons express various G protein-coupled receptors (GPCRs) with different coupling

Expanded autologous skin keratinocytes are currently used in cutaneous cell therapy, and embryonic-stem-cell-derived keratinocytes could become a complementary alternative. Regardless of keratinocyte provenance, for efficient therapy it is necessary to preserve immature keratinocyte precursors during cell expansion and graft processing.
