These QSPR (quantitative structure-property relationship) plots display the usual approximately linear relationships similar to those of the alkyl and chlorinated aromatic hydrocarbons. 

The structure of a chemical is responsible for the presence and magnitude of its properties. The properties can be energy levels and their derivatives, as well as physicochemical, or biological, properties. To avoid discrimination between the different properties (which are the subject of detailed consideration in Chapters 3, 4, and 6) in the context of quantitative relationships between structural descriptors (i.e., topological indices [TIs]) and various properties, we will use the broader abbreviation QSPR (Quantitative Structure-Property Relationship). 

QSAR Quantitative structure-activity relationships (term used for ordinary molecules). QSPR Quantitative structure-property relationships (term used for polymers). 

So, although prodrugs can sometimes help, it makes more sense to develop soluble candidates in the first place than to count on some sort of deus ex machina to come to the rescue late in the project. Using solubility data, even if only kinetic, in prioritizing compounds and designing analogs, thus investigating QSPR quantitative structure-property relationships) in parallel with QSAR is the best way to do that (Box 8.4). 

QSPR Quantitative structure-property relationship. A quantitative relationship between a specified property and the structure of a compound. Very similar to QSAR but more relevant in coordination chemistry where properties rather than activities are usually referred to.
