Development of a simple proton nuclear magnetic resonance-based procedure to estimate the approximate distribution coefficient at physiological pH (logD7.4): Evaluation and comparison to existing practices
Research output: Contribution to journal › Journal article › Research › peer-review
In drug discovery, lipophilicity is a key parameter for drug optimization. Lipophilicity determinations can be both work and time consuming, especially for non-UV active compounds. Herein, an improved and simple 1H NMR-based method is described to estimate the lipophilicity at physiological pH (logD7.4) in 1-octanol and D2O buffer. The method can be applied to both UV and non-UV active compounds. In addition, neither calibration curves nor internal/external standards are needed. We have demonstrated that logD7.4 can be accurately measured using 1H NMR for compounds within the logD7.4 interval between 0.7 and 3.3. The method was also compared to a previously described HPLC method.
