Abstract
The methyl eugenol receptor of the male oriental fruit fly (D. dorsalis) was further characterized by evaluating the role of the linear free energy parameters II 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 central unsaturation. Preference tests suggest that this simple and versatle odor receptor can serve as a model for investigation of molecular interactions between receptors and odorant molecules.This publication has 5 references indexed in Scilit:
