Phe-Met-Arg-Phe Like Peptide, Snail Helix aspersa is a FMRF-like peptide from visceral and somatic muscles of the snail Helix aspersa. FMRF (Phe-Met-Arg-Phe) is a neuropeptide peptide consisting of 4 amino acid residues.

At equivalent molar concentrations, both the salt and free forms of a compound exhibit comparable biological activity. Nevertheless, the salt form (Fosfructose trisodium) usually boasts enhanced water solubility and stability.

EH-201 is a low MW inducer of erythropoietin. EH-201 induces expression of erythropoietin PPAR-γ coactivator 1α (PGC-1α) and haemoglobin in astrocytes and PC12 neuronal-like cells. In vivo EH-201 treatment restores memory impairment as assessed by the passive avoidance test in SD Aβ and KA mouse models.
