Lipophilicity modulations by fluorination correlate with membrane partitioning
Lipophilicity modulations by fluorination correlate with membrane partitioning
Bioactive compounds generally need to cross membranes to arrive at their site of action. The octanol-water partition coefficient (lipophilicity, logP
OW) has proven to be an excellent proxy for membrane permeability. In modern drug discovery, logP
OW and bioactivity are optimized simultaneously, for which fluorination is one of the relevant strategies. The question arises as to which extent the often subtle logP modifications resulting from different aliphatic fluorine-motif introductions also lead to concomitant membrane permeability changes, given the difference in molecular environment between octanol and (anisotropic) membranes. It was found that for a given compound class, there is excellent correlation between logP
OW values with the corresponding membrane molar partitioning coefficients (logK
p); a study enabled by novel solid-state
19F NMR MAS methodology using lipid vesicles. Our results show that the factors that cause modulation of octanol-water partition coefficients similarly affect membrane permeability.

Abstract
Bioactive compounds generally need to cross membranes to arrive at their site of action. The octanol-water partition coefficient (lipophilicity, logP
OW) has proven to be an excellent proxy for membrane permeability. In modern drug discovery, logP
OW and bioactivity are optimized simultaneously, for which fluorination is one of the relevant strategies. The question arises as to which extent the often subtle logP modifications resulting from different aliphatic fluorine-motif introductions also lead to concomitant membrane permeability changes, given the difference in molecular environment between octanol and (anisotropic) membranes. It was found that for a given compound class, there is excellent correlation between logP
OW values with the corresponding membrane molar partitioning coefficients (logK
p); a study enabled by novel solid-state
19F NMR MAS methodology using lipid vesicles. Our results show that the factors that cause modulation of octanol-water partition coefficients similarly affect membrane permeability.
