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

The effects of hydrostatic pressure on the structure and stability of porcine odorant-binding protein (pOBP) in the presence and absence of the odorant molecule 2-isobutyl-3-methoxypyrazine (IBMP) were studied by steady-state and time-resolved fluorescence spectroscopy as well as by molecular dynamics

The effects of light exposure on 3-isobutyl-2-methoxypyrazine (IBMP) accumulation and degradation in Vitis vinifera L. cv. Cabernet Franc berries were assessed by comparison of shaded and exposed clusters within the same vine throughout a growing season. Twenty-seven vines were shoot-thinned

This report has investigated the seasonal temperatures influences (winter and summer) of five vineyards at different altitudes on the concentrations of 2-methoxy-3-isobutylpyrazine (MIBP), alpha- and beta-ionone, and beta-damascenone in 2004 or 2005 vintages of Cabernet Sauvignon wines from Santa Catarina
