本文描述了非甾体抗炎药氟芬那酸(FFA)前所未有的多态性。通过聚合物诱导异核(PIHn)和低温固-固相变获得了9个多晶态。六种这些形式的结构说明,除了两种以前已知的形式,使FFA无可争议的八构象。尽管至少一种其他形式的FFA的结构仍然难以捉摸,但通过PIHn在一种结晶条件下发生的大多数这些多晶态表明,在这种NSAID中,导致相选择的动力学因素之间存在良好的相互作用。
The unprecedented polymorphism of the non-steroidal anti-inflammatory drug (NSAID) flufenamic acid (FFA) is described here. Nine polymorphs were accessed through the use of polymer-induced heteronucleation (PIHn) and solid-solid transformation at low temperature. Structural elucidation of six of these forms, in addition to the two previously known forms, makes FFA indisputably octamorphic. Although the structure of at least one other form of FFA remains elusive, the occurrence of most of these polymorphs under one crystallization condition through PIHn illustrates that a fine interplay exists among the kinetic factors that lead to phase selection in this NSAID.
