Analgesia with minimal tolerance and dependence by a mu opioid receptor agonist that also binds filamin A

摘要

A composition and method are disclosed that utilize an isolated polypeptide or analog thereof to inhibit the interaction of a mu-opioid receptor with filamin A. A contemplated polypeptide has an amino acid residue sequence illustrated by the formula: W-[X1X2X3- . . . X43X44X45]nValAlaX48GlyLeu[X51X52X53 . . . X94X95X96]m-Y, wherein the various elements are defined elsewhere. A contemplated method can be used to select a VAKGL-binding compound.
