ChemInform Abstract
The conformationally restrained Trp-Phe mimetic (X) is constructed which is designed to mimic the size and direction of the dipole moment as well as the orientation of the two central amino acid side chains in a β-turn. The tachykinin receptor affinities of (X) are evaluated and compared to those of the NK-2 antagonist MEN 10627.
