Discovery of orally bioavailable NK1 receptor antagonists
摘要:
Benzyloxyphenethylpiperazines are a new class of high affinity NK1 receptor antagonists. Oral bioavailability and selectivity can be fine tuned by the nature of the substituents on the basic nitrogen atom. Addition of substituents with a carboxylic acid group led to very selective and orally active NK1 antagonists free of interaction with L-type calcium channels. (C) 2003 Elsevier Science Ltd.

piperazine derivatives combining NK(1) antagonism and serotoninreuptakeinhibition is described. Compound 7u was shown to be active in animal models of 5-HT reuptakeinhibition and central NK(1) receptor blockade, and was demonstrated to be orally active in an integrated model sensitive to both mechanisms. This class of compounds potentially represents a new generation of antidepressants.
