A systematic study of trends in the lipophilicity of prominent representatives of the opioid family, including natural, semisynthetic, synthetic, and endogenous neuropeptide opioids, is described. This was enabled by a straightforward 1H NMR-based logP/D determination method developed for compounds holding at least one aromatic hydrogen atom. Moreover, the new method enables a direct simultaneous logD determination of opioid mixtures, overcoming the high sensitivity of this family to the measurement conditions, which is critical when a determination of the exact ΔlogD values of matched pairs is required. Interpretation of the experimental ΔlogD7.4 values of selected matched pairs, focusing inter alia on the 3-OMe and 14-OMe motifs in morphinan opioids, is suggested with the aid of DFT calculations and may be useful for the discovery of new opioid therapeutics.

通过直接、同时基于 1H NMR 的 logP/D 测定(单独测定和混合测定)解决阿片类药物亲脂性挑战



描述了对阿片类药物家族(包括天然、半合成、合成和内源性神经肽阿片类药物)著名代表的亲脂性趋势的系统研究。这是通过一种简单的基于1 H NMR 的 log P / D测定方法实现的,该方法是为含有至少一个芳香族氢原子的化合物而开发的。此外,新方法能够直接同时测定阿片类药物混合物的 log D ,克服了该系列对测量条件的高敏感性,这在需要确定匹配对的精确 Δlog D值时至关重要。借助 DFT 计算建议对所选匹配对的实验 Δlog D 7.4值进行解释,尤其关注吗啡喃阿片类药物中的 3-OMe 和 14-OMe 基序,并且可能有助于发现新的阿片类药物疗法。
