Recent data support the evidence that some molecules can activate ORs though they lack of the protonated amine, generally regarded to as the fundamental pharmacophore. Among such unusual ligands, we discovered the agonist c[YpwFG], having a good MOR affinity (Ki 34nM), that is an effective and potent analgesic for visceral pain when administered peripherally (i.p ED50 1,25mg/kg; s.c. ED50 2,7mg/kg), and retains moderate central analgesic effects (tail-flick, 20mg/kg).

Abstract
Recent data support the evidence that some molecules can activate ORs though they lack of the protonated amine, generally regarded to as the fundamental pharmacophore. Among such unusual ligands, we discovered the agonist c[YpwFG], having a good MOR affinity (Ki 34nM), that is an effective and potent analgesic for visceral pain when administered peripherally (i.p ED50 1,25mg/kg; s.c. ED50 2,7mg/kg), and retains moderate central analgesic effects (tail-flick, 20mg/kg).File in questo prodotto:
