Identification of novel and orally active spiroindoline NPY Y5 receptor antagonists
摘要:
A series of spiroindoline-3,40-piperidine derivatives were synthesized and evaluated for their binding affinities and antagonistic activities at Y5 receptors. Potent Y5 antagonists were tested for their oral bioavailabilities and brain penetration in rats. Some of the antagonists showed good oral bioavailability and/ or good brain penetration. In particular, compound 6e was orally bioavailable and brain penetrant, and oral administration of 6e inhibited bPP-induced food intake in rats with a minimum effective dose of 10 mg/ kg.

Compounds of the general formula (I):
1
wherein Ar
1
represents optionally substituted aryl or heteroaryl;
n represents 0 or 1;
T, U, V, and W each independently represent nitrogen atom or optionally substituted methine group, where at least two of them represent the said methine group;
X represents methine or hydroxy substituted methine;
Y represents an optionally substituted imino or oxygen atom are described and claimed. These novel spiro compounds are useful as neuropeptide Y receptor antagonists and as agents for the treatment of various kinds of cardiovascular disorders, central nervous system disorders, metabolic diseases and the like.
The present invention relates to compounds of Formula (I)
or a pharmaceutically acceptable salt thereof; processes for the preparation of the compounds; intermediates used in the preparation of the compounds; compositions containing the compounds; and uses of the compounds in treating diseases or conditions associated with fatty acid amide hydrolase (FAAH) activity.
