Abstract

In the salt (5α,6α)-6-[(2,5,8,11,14,17,20-hepta-oxadocosan-22-yl)-oxy]-3,14-dihy-droxy-17-(prop-2-en-1-yl)-4,5-ep-oxy-morphinan-17-ium hydrogen oxalate, C34H54NO11C2HO4- the polyether unit of the naloxegol cation adopts the shape of a squashed open letter 'O'. In the crystal, the hydrogen oxalate anions are linked into a chain by O-H⋯O hydrogen bonds. Each naloxegol unit is hydrogen bonded to three hydrogen oxalate ions via two O-H⋯O and one N-H⋯O inter-actions. The resulting hydrogen-bonded two-dimensional layer structure is 3,5-connected and has the 3,5 L50 topology.

Chemical context

Naloxegol {(5α,6α)-17-allyl-6-[(20-hy­droxy-3,6,9,12,15,18-hexa­oxaicos-1-yl)­oxy]-4,5-ep­oxy­morphinan-3,14-diol} is a pegylated derivative of naloxone which serves as a peripherally acting m-opioid receptor antagonist. This compound was developed for the oral treatment of opioid-induced constipation in adults with chronic non-cancer pain, and is currently marketed under the trade name Movantik by AstraZeneca. Åslund et al. (2012 ▸) have described two forms, denoted as A and B, of naloxegol oxalate. Form B was reported as showing ‘a sharp endothermic peak at 92.5° C’ (365.5 K) in the DSC thermogram with a heat of fusion of Δfus H = 96.1 J g−1 (71.29 kJ mol−1). Herein we report the crystal structure of naloxegol hydrogen oxalate (I) (C34H54NO11 + C2HO4 −), which is identical with form B described by Åslund et al. (2012 ▸). The unequivocal identity with form B is evidenced by the match of the X-ray powder diffraction data and the good agreement of the melting data [T fus(onset) = 363.9 ± 0.3 K, T fus(peak) = 366.7 ± 0.3 K, Δfus H = 70.4 ± 0.6 kJ mol−1] with those reported by Åslund et al. (2012 ▸).

Structural commentary

The geometry of the morphine scaffold in the title structure (I) is very similar to that of the parent mol­ecule in the naloxone hydro­chloride dihydrate structure (Klein et al., 1987 ▸), except for the conformation of the cyclo­hexyl ring (C2–C6/C11) (Figs. 1 ▸ and 2 ▸). In (I), the puckering parameters for this ring of q = 85.3 (2)° and θ = 76.6 (3)° indicate a conformation between boat and twist boat (Cremer & Pople, 1975 ▸; Boeyens, 1978 ▸). The conformation of the 2-propenyl group at N8 is characterised by the torsion angle N8—C43—C44—C45 of 133.6 (4)°, which differs substanti­ally from the corresponding value, −96.2°, in the naloxone hydro­chloride dihydrate. The polyether unit adopts the shape of a squashed open letter O. Using the nomenclature for torsion angles recommended by Markley et al. (1998 ▸), the conformation of the fragment (C3, O19–C41) can be described by the sequence tg + t tg −[[t]] ttg − g − g − g + g + g − t tg − t tg − t. All O—C—C—O angles are gauche except for O25—C26—C27—O28. Six consecutive gauche-type torsion angles are associated with a 180° turn within the chain section (C26–O34) (Fig. 1 ▸, Table 1 ▸). The hydrogen oxalate anion displays a twisted conformation with a torsion angle O1O—C2O—C4O—O5O of −143.3 (3)°.

Supra­molecular features

The naloxegol cation contains one NH group and two OH groups, which can serve as hydrogen-bond donor groups, and the hydrogen oxalate contains another OH group. Neighbouring hydrogen oxalate ions are hydrogen bonded (Table 2 ▸) to one another (O6O—H6O⋯O1O iii), so that a chain structure parallel to the b axis is formed. Each naloxegol unit serves as a bridge between two such hydrogen oxalate chains in that it provides two bonds, O42—H42⋯O3O ii and N8—H8⋯O1O i, to two different anions belonging to one hydrogen-bonded hydrogen oxalate chain, The third bond, O46—H46⋯O5O, connects to a second anion chain (Fig. 3 ▸). Altogether, each naloxegol cation forms three hydrogen bonds to three hydrogen oxalate ions, and each anion is engaged in five one-point hydrogen-bonding inter­actions with two hydrogen oxalate and three naloxegol units. The 3,5-connected layer structure (Fig. 4 ▸) resulting from these inter­actions lies in the ab plane. It possesses the 3,5L50 topology and has the point symbol (3.52)(32.53.64.7), wherein the naloxegol and hydrogen oxalate nodes are represented by the string (3.52) and (32.53.64.7), respectively.

The net is viewed along the c axis. Note that the naloxegol nodes are placed at the centroid of the mol­ecule rather than the center of its morphine scaffold.

Database survey

Crystal structures of a hydro­chloride dihydrate (Karle, 1974 ▸; Sime et al., 1975 ▸; Klein et al., 1987 ▸; see Fig. 2 ▸) and a hydro­chloride anhydrate (Sugimoto et al., 2007 ▸) of the parent mol­ecule naloxone are known. Heptaglyme (heptaethyleneglycol dimethyl ether) has been used as a multidentate ligand in Ba (FIXKAY; Wei et al., 1987 ▸), Ca (RUFWUK; Arunasalam et al., 1997 ▸) and Gd (YOMBUX; Baxter et al., 1995 ▸) complexes. The hepta­glyme conformations in these crystals differ substanti­ally from the chain geometry found in (I). For example, the hepta­glyme complex with barium thio­cyanate displays a regular sequence tg − t tg + t tg − t tg + t tg − tg + t with sign alternation (Wei et al., 1987 ▸).

Synthesis and crystallization

Naloxegol was obtained as a viscous transparent yellow oil (purity 95.05%). Approximately 4000 mg (6.14 mmol) of the free base were dissolved in 30 ml of ethyl­acetate and 774 mg (1 meq) of oxalic acid dihydrate (Merck) suspended in 20 ml of ethyl­acetate. The free-base solution was added dropwise to the suspended counter-ion. Stirring at room temperature for 15 minutes transformed the gel-like material into a suspension. The oxalate salt formation was complete after continued stirring for 12 h at ambient temperature. The slurry was then separated from the mother liquor by centrifuge and then dried in vacuo at ambient temperature (yield 3700 mg = 4.99 mmol = 81% of theory). The PXRD pattern of the dried product was found to match that of form B reported in Åslund et al. (2012 ▸). A sample of form B (50 mg) was dissolved in 0.3 ml of 2-propanol under slight heating. Filtration through a syringe filter (pore size 0.44 microns) yielded a clear solution. The solution was allowed to cool to room temperature. Crystallization in a closed vial yielded single crystals suitable for a crystal structure determination. Typical crystal morphologies of (I) obtained by evaporation from different organic solvents are shown in Fig. S1 of the Supporting information.

Refinement

Crystal data, data collection and structure refinement details are summarized in Table 3 ▸. All H atoms were identified in difference maps. Methyl H atoms were idealized and included as rigid groups allowed to rotate but not tip and refined with U iso set to 1.5U eq(C) of the parent carbon atom. All other H atoms bound to carbon atoms were positioned geometrically and refined with U iso set to 1.2U eq(C) of the parent carbon atom. Hydrogen atoms in OH and NH groups were refined with restrained distances [O—H = 0.84 (1) Å; N—H = 0.88 (1) Å] and their U iso parameters were refined freely. The absolute structure was established by anomalous-dispersion effects.

The largest residual peak of 0.73 e Å−3 is located 1.00 Å from C30. An alternative refinement of a disorder model with a split C30 position was attempted, but resulted in a few unreasonably short intra­molecular H⋯H distances for the minor disorder fragment. This feature could not be eliminated even with the aplication of a suitable anti-bumping restraint. The topology of the hydrogen-bonded structures was determined and classified with the programs ADS and IsoTest of the TOPOS package (Blatov, 2006 ▸) in the manner described by Baburin & Blatov (2007 ▸).

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
