Biphalin is a dimeric enkephalin endogenous peptide (Tyr-D-Ala-Gly-Phe-NH)2 composed of two tetrapeptides derived from enkephalins connected ‘tail-to-tail’ by a hydrazide bridge. The presence of two distinct pharmacophore confers of Biphalin highly affinity for both μ and δ opioid receptors (with a with an EC50 of about 1-5 nM for both μ and δ receptors) therefore it has analgesic activity.Biphalin presents a considerable antinociceptive profile.
