Parallel solution- and solid-Phase synthesis of spirohydantoin derivatives as neurokinin-1 receptor ligands

Abstract

The combination of the 3,5-bis(trifluoromethyl)phenyl group with a spirohydantoin motive as a central scaffold was the basis for the design of a combinatorial library targeted towards the neurokinin-1 receptor. A solution- and solid-phase procedure is described and binding affinities of representative compounds presented.
