Author is Bredikhin, Alexander A.; Zakharychev, Dmitry V.; Gubaidullin, Aidar T.; Bredikhina, Zemfira A..
In addition to the previously known A-rac and B-rac polymorphs of the chiral drug metaxalone 1, an enantiopure A-(S)-form was obtained and studied. According to x-ray anal., the crystalline organization of this form is close to the A-rac-1 polymorph. Crystallization of metaxalone melts is accompanied by the formation of a previously unknown metastable C-phase, which in the case of both racemic and enantiomeric samples are transformed into A-rac-1 or A-(S)-1. Anal. of the PXRD and IR spectra of crystalline samples revealed a similarity of the internal structure for the A-(S)-1, A-rac-1, C-(S)-1, and C-rac-1 crystalline forms and the essential difference of all of these phases from the B-rac-1 phase. According to the thermochem. data, the dependences of the change in the Gibbs free energy for all the phases studied are plotted in the interval from the m.p. to 20°. Under standard conditions, the crystalline modifications of metaxalone, relative to ΔG0, form such a series: B-rac-1 < A-(S)-1 ≈ A-rac-1 < C-rac-1 < C-(S)-1. A model that describes all the exptl. revealed features of metaxalone crystallization is proposed.
