- Synthesis of the phenylpyridal scaffold as a helical peptide mimetic
-
Phenylpyridal- and phenyldipyridal-based scaffolds have been designed and synthesized as novel helical peptide mimetics. The synthesis required optimisation and selective alkylation in producing 2,6-functionalized 3-hydroxypyridine derivatives for a convergent scheme. The pyridine analogues were coupled by a series of Suzuki/Stille types cross-coupling reactions. A series of biaryl and ter-aryl substituted heterocycles were produced. The synthetic approach was concise and high yielding allowing large variability at the wanted sidechain attachment points. A number of compounds were synthesised to show the versatility of the strategy.

- BIPYRIDYL AMINES AND ETHERS AS MODULATORS OF METABOTROPIC GLUTAMATE RECEPTOR-5
-
The present invention is directed to novel bipyridyl amine and ether compounds such as those of Formula (I): (I) (where R?1#191, R?2#191, R?3#191, X and Y are as defined herein) which are mGluR5 modulators useful in the treatment or prevention of diseases and conditions in which mGluR5 is involved, including but not limited to psychiatric and mood disorders such as schizophrenia, anxiety, depression, bipolar disorders, and panic, as well as in the treatment of pain, Parkinson’s disease, cognitive dysfunction, epilepsy, circadian rhythm and sleep disorders, such as shift-work induced sleep disorder and jet-lag, drug addiction, drug abuse, drug withdrawal, obesity and other diseases. The invention is also directed to pharmaceutical compositions comprising these compounds. This invention further provides a method of treatment of these disorders and conditions by the administration of an effective amount of these novel bipyridyl amine and/or ether compounds and/or compositions containing these compounds.
