Design, synthesis, and evaluation of an improved enantioselective naproxen selector
摘要:
The design, synthesis, and evaluation of an improved selector for the enantiomers of the nonsteroidal anti-inflammatory drug, naproxen, are described. So as to utilize the principle of reciprocity, two chiral stationary phases (CSPs) derived from (S)-naproxen were produced and HPLC techniques were used to screen candidate naproxen selectors. By determining how the structural features of the candidates influence enantioselective recognition by naproxen, a hypothetical chiral recognition mechanism for enantioselective recognition of naproxen was developed and used to design a selector which was incorporated into a new CSP. This comparatively simple CSP shows significant improvement in the separation of underivatized naproxen enantiomers relative to previous methods. Related compounds such as ibuprofen, ketoprofen, cicloprofen, fenoprofen, etc. are also resolved into their component enantiomers by this CSP.

(EN) The invention relates to a chiral selector useful in separating underivatized enantiomers of non-steroidal anti-inflammatory agents, particularly naproxen and other arylacetic acid compounds, and relates to a process for achieving such separation utilizing the chiral selector, which is also useful in achieving the enantiomeric separation of amines, alcohol derivatives, epoxides and sulfoxides. The invention is also directed to an apparatus which comprises the chiral selectors.(FR) Sélecteur chiral utile dans la séparation d'énantiomères non dérivés d'agents anti-inflammatoires non stéroidiens, notamment du naproxène et d'autres composés de l'acide arylacétique. L'invention décrit aussi un procédé permettant d'effectuer cette séparation en utilisant le sélecteur chiral, ce procédé étant également utile dans la séparation énantiomère d'amines, de dérivés d'alcool, d'époxydes et de sulfoxydes. L'invention se rapporte également à un appareil comprenant les sélecteurs chiraux.
