Potent NK1 Receptor Antagonists: Synthesis and Antagonistic Activity of Various Heterocycles with an N-(3,5-Bis(trifluoromethyl)benzyl)-N-methylcarbamoyl Substituent.
as an anchor by fixing the pendant phenyl group in a desirable orientation for receptor binding, and (iii) since compounds with aromatic rings (2) and those with aliphatic rings (3) as ring B both show good potency, this ring does not seem to be essential for receptor recognition. Among the compounds synthesized, the tetrahydropyridine derivatives 3a, 3b and 3f exhibited excellent inhibitory effects
