Application
2-Isobutyl-3-methoxypyrazine has been employed as a model odorant molecule during an electrochemical assay for the detection of odorant molecules based on a rat odorant-binding protein (rOBP3).
General description
2-Isobutyl-3-methoxypyrazine, a potent bell-pepper odourant, has been found to bind to cow olfactory mucosa homogenate.

2-Isobutyl-3-methoxypyrazine, a potent bell-pepper odorant, binds to cow olfactory mucosa homogenate. The receptor is saturable in the micromolar range and is competitively inhibited by other bell-pepper odourants, but not by other pyrazines of different odours. Other tissues do not bind

We developed an electrochemical assay for the detection of odorant molecules based on a rat odorant-binding protein (rOBP3). We demonstrated that rOBP3 cavity binds 2-methyl-1,4-naphtoquinone (MNQ), an electrochemical probe, as depicted from the decrease of its electrochemical signal, and deduced
