(Arg)9 TFA

CAS No. 2283335-13-5

(Arg)9 TFA ( Nona-L-arginine (TFA),Peptide R9 (TFA) )

Catalog No. M22290 CAS No. 2283335-13-5

(Arg)9 TFA (Nona-L-arginine TFA), a cell-penetrating peptide, exhibits neuroprotective activity with an IC50 of 0.78 μM in the glutamic acid model.Poly-arginine (e.g. (Arg)9) and arginine-rich peptides (e.g. TAT, penetratin), which belong to a class of peptides with cell-penetrating properties are neuroprotective.

  • Description
    (Arg)9 TFA (Nona-L-arginine TFA), a cell-penetrating peptide, exhibits neuroprotective activity with an IC50 of 0.78 μM in the glutamic acid model.Poly-arginine (e.g. (Arg)9) and arginine-rich peptides (e.g. TAT, penetratin), which belong to a class of peptides with cell-penetrating properties are neuroprotective. (Arg)9 provides significant neuroprotection in a dose–response manner following glutamic acid exposure (IC50=0.78 μM). Following kainic acid exposure, (Arg)9 is neuroprotective, but less effective than in the glutamic acid model (IC50=0.81 μM). (Arg)9 also shows neuroprotection following in vitro ischemia (IC50=6 μM).(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 permanent middle cerebral artery occlusion (MCAO) reduces infarct volume.
