Lipophilicity has a dominant effect on many parameters that determine unbound drug exposure as well as drug potency. Despite this, analysis of a large body of drug data indicates lipophilicity has no consistent directional impact on dose. This can be rationalized based on the interplay of the effects of lipophilicity on individual parameter values in pharmacokinetic equations. We believe this undermines the effectiveness of strategies that target specific ranges for drug parameters for which lipophilicity plays such a dominant role. As a result, our research organization no longer leverages the common approach of screening for low intrinsic clearance to target high unbound exposure . Instead, we advocate for approaches less biased to lipophilicity through optimization of key parameter ratios controlling dose. We believe this improves efficiency in drug discovery by enabling exploration of broad physicochemical space.
