Source of material
11-(4-(dimethylamino)phenyl)-17-hydroxy-13-methyl-17-(prop-1-yn-1-yl)-1,2,6,7,8,11,12,13,14,15,16,17-dodecahydro-3H-cyclopenta[a]phenanthren-3-one was purchased. A small amount of this compound (200 mg) was dissolved in dioxane (0.5 mL). 4 mL acetonitrile were added to the solution dropwise slowly, stirred and filtered to get the title compound.
Experimental details
Hydrogen atoms were placed in calculated positions and were included in the refinement using the riding model approximation, with Uiso(H) set to 1.2Ueq(C) and Uiso(H) = 1.5Ueq (CH3, O).
Discussion
Mifepristone (11′-[p-(Dimethylamino)phenyl]-17′-hydroxy-17-(1-propynyl)estra-4,9-dien-3-one, also known as RU-486 and under the systematic IUPAC name 11-(4-(dimethylamino)phenyl)-17-hydroxy-13-methyl-17-(prop-1-yn-1-yl)-1,2,6,7,8,11,12,13,14,15,16,17-dodecahydro-3H-cyclopenta[a]phenanthren-3-one) has a high affinity for the progesterone receptor [3]. So it can be used as a potent oral antiprogestogen [4]. Mifepristone is also effective in the second trimester of pregnancy [5]. Mifepristone was classified as a low solubility/low permeability drug (Biopharmaceutical classification system, BCS class IV) [6]. For BCS class IV drugs, super saturable API (Active pharmaceutical ingredient) solid forms such as salts, solvates, cocrystals and anhydrates would be effective to increase the bioavailability of the drug [7, 8] .
Some crystal structure of mifepristone polymorphs are reported [9, 10] . The asymmetric unit cell comprises one Mifepristone and two acetonitrile molecules (cf. the figure). Geometric parameters are all in the expected ranges. The intermolecular hydrogen bonds and van der Waals forces in the title crystal structure change its properties to some extent. Compared to pure Mifepristone, the acetonitrile solvate had a good stability (40 °C/75% RH for one month) and showed an improved dissolution profile (in both 0.2% sodium dodecyl sulfate (SDS) solution and 0.5% SDS solution).
