Application

Chelerythrine chloride has been used:
  • as a supplement in heat-inactivated late-embryo extract or late-embryo extract to inhibit protein kinase C (PKC) activity
  • for in vitro Xenopus experiments
  • as a PKC inhibitor in HL-1 cells, to block the PKC pathway to study its effects on doxazosin-induced galectin-3 and collagen expression

Biochem/physiol Actions

Chelerythrine chloride (CHE) is capable of preventing the growth and apoptosis in human gastric cancer BGC-823 cells. It possesses several biological effects and also can induce the phosphorylation of a ~20 kDa protein present in the mitochondrial fraction of the rat retina.

PKMζ is an autonomously active, atypical protein kinase C (aPKC) isoform that is both necessary and sufficient for maintaining long-term potentiation (LTP) and long-term memory. The myristoylated ζ-pseudosubstrate peptide, ZIP, potently inhibits PKMζ biochemically in vitro, within cultured cells, and
