General description

2-Isobutyl-3-methoxypyrazine, a potent bell-pepper odourant, has been found to bind to cow olfactory mucosa homogenate.

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).

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

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

In the present study we examine the enthalpy of binding of 2-methoxy-3-isobutylpyrazine (IBMP) to the mouse major urinary protein (MUP), using a combination of isothermal titration calorimetry (ITC), NMR, X-ray crystallography, all-atom molecular dynamics simulations, and site-directed mutagenesis.
