Pyrazine analogues are active components of wolf urine that induce avoidance and fear-related behaviors in deer

Frontiers in Behavioral Neuroscience, 2014
Our previous studies indicated that a cocktail of pyrazine analogues, identified in wolf urine, induced avoidance and fear behaviors in mice. The effects of the pyrazine cocktail on Hokkaido deer (Cervus nippon yesoensis) were investigated in field ...

Reactions and Syntheses of Pyrazines

YAKUGAKU ZASSHI, 1997
This review deals with syntheses and reactions of pyrazines, especially, of 2,5-disubstituted pyrazines. The description was made in due to order of 1) synthesis and properties of 2,5-disubstituted pyrazines, 2) synthesis of 2,5-disubstituted pyrazine N-oxides, 3) synthesis of pyrazinols, 4) synthesis and utilization of pyrazinethiols; preparation of ...
