Election Impact Mass Spectra of para-Substituted N-Heteroaryl Benzylamines
摘要:
The 70 eV electron impact mass spectra of some para-substituted N-heteroaryl benzylamines, synthesized through the corresponding Schiff bases, are reported. Typical fragmentation patterns are discussed with the aid of mass analyzed ion kinetic energy spectra and exact mass measurements. The compounds are relatively stable under electron impact, the molecular ion being the base peak or the second most intense ion in the spectra. The dominating breakdown process is the benzylic cleavage, that gives rise to the base peak in some of the investigated compounds and to the second intense peak in others.
This invention relates to an anti-dementia agent which uses a BEC 1 potassium channel inhibitor as the active ingredient.
It was proved that the BEC 1 potassium channel inhibitor has an action to improve learning disorder and is useful as a preventive or therapeutic agent for diseases, preferably dementia, in which the BEC 1 potassium channel is considered to be concerned.
Illustratively, it was confirmed by an in vivo test that the BEC 1 potassium channel inhibitor has an action to improve learning disorder.
Also, it was found that a compound having 2,4,6-triamino-1,3,5-triazine has a BEC 1 potassium channel inhibitory action.

The present invention relates to novel compounds, in particular novel pyridinone derivatives according to Formula (I)
wherein all radicals are defined in the application and claims. The compounds according to the invention are positive allosteric modulators of metabotropic receptors - subtype 2 ("mGluR2") which are useful for the treatment or prevention of neurological and psychiatric disorders associated with glutamate dysfunction and diseases in which the mGluR2 subtype of metabotropic receptors is involved. In particular, such diseases are central nervous system disorders selected from the group of anxiety, schizophrenia, migraine, depression, and epilepsy. The invention is also directed to pharmaceutical compositions and processes to prepare such compounds and compositions, as well as to the use of such compounds for the prevention and treatment of such diseases in which mGluR2 is involved.
