摘要

The design and synthesis of potent and selective neurokinin NK-2 receptor agonists 12 (GR64349) and 31 are described, together with structureactivity relationships for related analogues. Compound 12 (E&= 3.7 nM at NK-2 receptors in the rat colon; selectivity> low- and> 300-fold with respect to NK-1 and NK-3 receptors, respectively) was derived by incorporation of a Gly-Leu y-lactam conformational constraint into the C-terminal region of ...
