Abstract:
:Ureas derived from two substituted 3-aminopyrrolidine subunits were prepared as constrained analogs of a linear lead compound and tested as antagonists of the MCH(1) receptor. The series was optimized for substitution and stereochemistry to generate a functional antagonist with a K(i) of 3.3 nM and IC(50) of 12 nM (GTPgammaS).
