Traditional lipophilicity parameters (log P and log D) are well-known physico-chemical descriptors largely used in QSAR studies. Besides their numerical value, log P data contain a variety of information about inter- and intramolecular forces affecting partitioning and its related biological phenomena. The deconvolution of information from log P can be accessed only by adequate interpretative tools, such as new lipophilic-combined descriptors, of which features and some applications are presented in this review.
