Source of materials
A mixture of berberine chloride (370 mg, 1 mmol), NaOH (40 mg, 1 mmol) and daidzein (254 mg, 1 mmol) with 0.1 mL methanol added, was ground with a LAB WIZZ 320 ball mill in a 25 mL steel vessel for 15 min with a 15 mm steel ball at 30 Hz. The resulting powder was washed with water to remove the by-product NaCl and then re-crystallized in MeOH to give rise to yellow needle crystals.
Experimental details
The structure was solved by direct methods and refined on F2 by full-matrix least-squares methods using SHELXL [2]. H atoms on C atoms were located geometrically with Uiso(H) = 1.2 Ueq(C) or 1.5 Ueq(C). H atoms bonded to O were located by difference Fourier maps and the displacement factors were refined freely. Difference Fourier maps indicate disorder for one of the two methoxy groups, which could not be modelled satisfactorily against the available room-temperature data.
Comment
Flavonoids are a class of natural products with various pharmacological activities such as antioxidant and antitumor properties [4]. Multi-component crystals of flavonoids have been exploited recently [5]. Flavonoids have been also explored as cocrystal formers with other drug molecules [6].
Daidzein, 7-hydroxy-3-(4-hydroxyphenyl)-4H-1-benzo-pyran-4-one, is an isoflavone compound exhibiting a range of medicinal properties [7]. With two hydroxyl groups at opposite ends of the molecular structure it is a weak acid [8] capable of forming molecular salts and extended hydrogen-bonded structures. In this paper, we choose a basic natural product, berberine, as drug model. Daidzein crystallized in methanol with berberine to give rise to a 1:1:1 molecular salt hydrate, [C20H18NO4]+[C15H9O4]−⋅H2O⋅CH4O.
Difference Fourier maps show deprotonation of the 7-substituted hydroxyl group in the daidzein molecule. Hydrogen-bonded interactions between the resulting anion and 4′-substituted hydroxyl group [O4⋯O3], give rise to a 1D hydrogen-bonded chain along the [2 0 1] direction. The dihedral angle between the phenyl ring (C10—C15) and pyran ring (O1/C1—C2—C3/C8—C9) of daidzein is 41.14(7)°. The water molecule is hydrogen bonded to methanol and to O3 and O4 of the daidzein anion, thereby connecting the 1D chain into a 2D hydrogen-bonded layer. Berberine cations are located in between the 2D layers to give the host-guest arrays .
