Piperidyl amides as novel, potent and orally active mGlu5 receptor antagonists with anxiolytic-like activity
摘要:
High throughput screening led to the identification of nicotinamide derivative 2 as a structurally novel mGluR5 antagonist. Optimization of the modular scaffold led to the discovery of 16m, a compound with high affinity for mGluR5 and excellent selectivity over other glutamate receptors. Compound 16m exhibits a favorable PK profile in rats, robust anxiolytic-like effects in three different animal models of fear and anxiety, as well as a good PK/PD correlation. (C) 2009 Elsevier Ltd.

A class of substituted amino pyridine derivatives are of value in the treatment of diabetes. Some of the compounds also possess hypolipidaemic activity.
The compounds are represented by the formula (I):
wherein R3 is hydrogen, alkyl or an acidic function;
R2 is hydrogen or alkyl;
R4 and R' are hydrogen, alkyl or halogen;
Z is hydrogen, phenyl, alkyl or aralkyl;
Alk is alkylene and x is 0 or 1;
R1 is optionally substituted phenyl or naphthyl.
Most of the compounds of formula (I) are novel.
