Neuronorm is a Potent and Water Soluble Neurokinin A Receptor Antagonist

We report here the synthesis and preliminary pharmacological characterization of a novel water soluble Neurokinin A receptor antagonist named Neuronorm. The synthesis was achieved in high yield by a combination of classical peptide synthesis methodologies, in both solution and solid phase. The pharmacological properties as neurokinin A receptor antagonist were assessed in in vitro experiments on rat vas deferens and guinea pig trachea, and were compared to those of MEN10627.
