摘要：The methyl eugenol receptor of the male oriental fruit fly (Dacus dorsalis) has been further characterized by evaluating the role of the linear free energy parameters [prod] and {sigma} in the depolarization of the receptor by 37 substituted 3,4-dimethoxybenzenes. There was a strong positive correlation between the hydrophobic character of the primary substituent and intense odor and a positive correlation between the electron donating property of the primary substituent and intense odor. Maximum odor intensity was also associated with substituents of 3 atomic diameters and was improved by a center of unsaturation. Preference tests suggest that this simple and versatile odor receptor can serve as a model for investigation of molecular interactions between receptors and odorant molecules.
