Anwendung

Imidazolo-oxindole PKR inhibitor C16 has been used:
  • to rescue fear memory deficits and restore long-term potentiation (LTP) impairment in mice
  • to inhibit the strong induction of interferon stimulated genes (ISGs) after plasmid transfection in HeLa-S3 cells
  • to augment eukaryotic translation initiation factor 2 (eIF2) activity

Biochem./physiol. Wirkung

C16 exhibits a neuroprotective role in adult brain injuries.
Imidazolo-oxindole PKR inhibitor C16 is a selective inhibitor of RNA-dependent protein kinases (PKR, Eif2ak2). C16 is a first reported, potent and selective PKR inhibitor. Its inhibition effect on PKR is ATP-binding site directed. C16 specifically inhibits the apoptotic PKR/eIF2a signaling pathway without stimulating the proliferative mTOR/p70S6K signaling mechanism.

Leader (L) proteins encoded by cardioviruses are multifunctional proteins that contribute to innate immunity evasion. L proteins of Theiler's murine encephalomyelitis virus (TMEV), Saffold virus (SAFV), and encephalomyocarditis virus (EMCV) were reported to inhibit stress granule assembly in infected cells.
