WebThe molecular lipophilicity potential (MLP) offers a three-dimensional representation of lipophilicity, a molecular property encoding intermolecular recognition forces and intramolecular interactions. Methods. The interest and applications of the MLP in molecular modeling are varied, as ilustrated here. Results. WebThe pK a, solubility, and lipophilicity are among the most fundamental physicochemical properties of a drug candidate, and their measurements are essential for both in silico and in vitro evaluation of drug-like properties. In this chapter, the authors present some widely used methods for measuring these three parameters .
