In the past 15 years, it has become clear that physicochemical properties of drug candidates, such as lipophilicity and molecular mass, have an important influence on the likelihood of compound-related attrition during development. By analysing the properties of compounds described in patents from leading pharmaceutical companies between 2000 and 2010, this article indicates that a substantial part of the industry has not modified its drug design practices accordingly and is still producing compounds with suboptimal physicochemical profiles.
