(Arg)9 (Nona-L-arginine) is a cell-penetrating peptide (CPP) made up of 9 arginine residues, which is an inhibitor of serine endoprotease Furin. (Arg)9 has neuroprotective property, exhibits neuroprotective activity with an IC50 of 0.78 μM in the glutamic acid model[1][2]. | [Biological Activity]
(Arg)9 (Nona-L-arginine; Peptide R9) is a cell-permeable polypeptide with IC50 value of 0.78 μM for neuroprotection in a glutamate model experimental model. | [in vitro]
Poly-arginine (eg (Arg)9) and arginine-rich peptides (eg TAT, penetratin), which belong to a class of peptides with cell-penetrating properties are neuroprotective. It provides significant neuroprotection in a dose–response manner following glutamic acid exposure (IC 50 =0.78 μM). Following kainic acid exposure, (Arg)9 is neuroprotective, but less effective than in the glutamic acid model (IC 50 =0.81 μM). (Arg)9 also shows neuroprotection following in vitro ischemia (IC 50 =6 μM). | [in vivo]
(Arg)9) (D-isoform) is neuroprotective in rat stroke models. (Arg)9) is highly neuroprotective, with efficacy increasing with increasing arginine content, has the capacity to reduce glutamic acid-induced neuronal calcium influx and requires heparan sulfate preotoglycan-mediated endocytosis to induce a neuroprotective effect. (Arg)9) (D-isoform) administered intravenously at a dose of 1000 nmol/kg 30 min after reduces permanent middle cerebral artery occlusion (MCAO) infarct volume . | [target]
