Identifiers and physicochemical properties of the selected compounds.

<p>Full names, their abbreviations as used in the text and CAS registry numbers (CAS RN) are given as compound identifiers. Molecular weight (MW) and log<i>D</i> at pH 7.4 were predicted or calculated using Marvins' Calculater Plugins and Instant JChem 6.1.3 was used for structure database management (ChemAxon Kft.
