Fmoc-Ala-Glu-Asn-Lys-NH2 is a peptide inhibitor that selectively targets asparagine endopeptidase (AEP) and inhibits the cleavage of amyloid precursor protein (APP). AEP, a pH-controlled cysteine proteinase, plays a crucial role in the proteolytic processing of APP, and its activity is enhanced during the aging process [1].
JHU-58 is a novel dipeptide MrgC agonist. JHU-58 inhibited both mechanical and heat hypersensitivity in rats after an L5 spinal nerve ligation (SNL). JHU58 attenuated the evoked excitatory postsynaptic currents in substantia gelatinosa (SG) neurons in wild-type mice, but not in Mrg knockout mice, after peripheral nerve injury.
