ABSTRACT

A linear regression between odour detection thresholds and three basic physical properties (vapour pressure, water solubility and octanol/water partition coefficient) has been derived. The principles underlying this model are the transport process of the odorants from air to the olfactory neurons in the nasal epithelium. The regression was applied to odour detection thresholds measured from different authors separately, showing similar parameters. A general linear regression was obtained for odour detection threshold data from several authors and 121 chemicals. This regression allows a preliminary estimation of odour detection thresholds from literature data with fair accuracy. The coefficient of determination obtained, r^2^ = 0.769, indicates that these physical properties account for 77% of the odour threshold variance. Copyright © 2011 John Wiley & Sons, Ltd.

Tissue:plasma (P(t:p)) partition coefficients (PCs) are important parameters describing tissue distribution of drugs. The ultimate goal in early drug discovery is to develop and validate in silico methods for predicting a priori the P(t:p) for each new drug candidate. In this context, tissue composi

The octanol-water partition coefficients (Log P) of tripeptide diastereoisomers have been calculated by our recently developed method for predicting Log P from the results of AM1 semiempirical calculations. This method can distinguish different diastereoisomers. The differences arise from variations
