Crystal structure of 7-phenyl-7-(2,4,5-tri­methyl-3,6-dioxo­cyclo­hexa-1,4-dien-1-yl)hepta­noate 1,3-dihy­dr­oxy-2-(hy­dr­oxy­meth­yl)propan-2-aminium monohydrate: a new solid form of seratrodast

In the title hydrated salt, C4H12NO3+·C22H25O4·H2O, seratrodast [systematic name: 7-phenyl-7-(2,4,5-trimethyl-3,6-dioxo­cyclo­hexa-1,4-dien-1-yl)hepta­noic acid] crystallized with trometamol [systematic name: 2-amino-2-(hydroxyméth­yl)propane-1,3-diol] to form a monohydrated salt form of seratrodast. The carb­oxy­lic acid group of seratrodast has transferred its proton to the amino N atom of trometamol. In the crystal, the trometamol cations are linked to the water mol­ecules and to each other by N—H⋯O and O—H⋯O hydrogen bonds forming sheets parallel to (100). The seratrodast anions are linked to both sides of these sheets by O—H⋯O and C—H⋯O hydrogen bonds, forming a three-layer two-dimensional structure. After forming the title salt, the solubility of seratrodast was found to be greatly improved.

1. Chemical context

Seratrodast is the first thromboxane A2 receptor antagonist to have been developed as an anti-asthmatic drug (Samara, 1996[Samara, E. E. (1996). Cardiovasc. Drug. Rev. 14, 272-285.]). This drug mol­ecule with a carb­oxy­lic group is practically insoluble in water. Its new solid forms have been scarcely exploited and only a polymorphic transition was ever investigated (Urakami & Beezer, 2003[Urakami, K. & Beezer, A. E. (2003). Int. J. Pharm. 257, 265-271.]). Tris(hy­droxy­meth­yl)amino methane, commonly called trometamol, is often used as a buffer in biochemical studies. It has been successfully exploited for improving properties of APIs such as ketoprofen (Zippel & Wagenitz, 2006[Zippel, H. & Wagenitz, A. (2006). Clin. Drug Investig. 26, 517-528.]). In this study, trometamol was employed to co-crystallize with seratrodast to give rise to a hydrated salt. To the best of our knowledge, the title salt is the first multi-component crystalline form of seratrodast to be reported.

2. Structural commentary

The mol­ecular structure of the title salt is illustrated in Fig. 1[link]. It was clear from a difference Fourier map that the carb­oxy­lic group of seratrodast had transferred its proton to the amino N atom of trometamol. The bond distances C1—O1 and C1—O2 of the carboxyl­ate group of the seratrodast anion are 1.258 (4) and 1.232 (4) Å, respectively. The phenyl ring is normal to the dioxo­cyclo­hexa­diene ring, with a dihedral angle of 89.95 (19)°, and the alkyl chain has an extended conformation.

3. Supra­molecular features

In the crystal, the trometamol cations are linked to the water mol­ecules and to each other by N—H⋯O and O—H⋯O hydrogen bonds, forming sheets parallel to (100); see Table 1[link] and Fig. 2[link]. The seratrodast anions are linked to both sides of these sheets by O—H⋯O and C—H⋯O hydrogen bonds, forming a three-layer two-dimensional structure (Fig. 3[link] and Table 1[link]). Further details of the hydrogen bonding are given below and in Table 1[link]. The carboxyl­ate anion inter­acts with one hydroxyl group of trometamol through strong hydrogen bonding [O6⋯O1 = 2.662 (3) Å]. There also exist hydrogen-bonding inter­actions between carboxyl­ate anion and water mol­ecule [O8⋯O2 = 2.617 (3) Å, O8⋯O1i = 2.667 (3) Å]. The protonated trometamol cation inter­acts with each other through three kinds of hydrogen-bonding inter­actions. An R22(11) heterosynthon is formed through hydrogen-bonding inter­actions between the hydroxyl groups [O5⋯O7iii = 2.714 (3) Å] and between the hydroxyl group and the amino group [N1⋯O6iii = 2.779 (3) Å]. Along the c axis, the R22(11) heterosynthon gives rise to a hydrogen-bonded chain of trometamol cations, which is further linked into a two-dimensional structure by hydrogen-bonding inter­actions between the amino and the hydroxyl groups [N1⋯O5ii = 2.935 (3) Å]. There also exist hydrogen-bonding inter­actions between water and trometamol [N1⋯O8i = 2.800 (4) Å; O7⋯O8iii = 2.686 (3) Å]. The various hydrogen-bonding inter­actions result in a two-dimensional layer structure in which the seratrodast anions are spread around two sides of the layer in an orderly manner (Table 1[link] and Fig. 3[link]).

4. Database survey

To the best of our knowledge, the title salt is the first multi-component crystalline form of seratrodast to be reported.

5. Synthesis and crystallization

Seratrodast (354 mg, 1 mmol) and trometamol (121 mg, 1 mmol) were dissolved in methanol (15 ml). The resulting solution was kept in air and after several days yellow block-like crystals of the title salt were obtained.

6. Solubility Studies

Excess amounts of seratrodast and the title salt were suspended in 10 ml of water in screw-capped glass vials, respectively. These vials were kept at 310 K and were stirred at 100 r.p.m. using a magnetic stirrer. After 72 h, the suspensions were filtered through a 0.2 µm syringe filter. The filtered aliquots were sufficiently diluted, and the absorbances were measured at 268 nm in triplicate. Finally, the concentration of seratrodast after 72 h in each sample was determined from the previously made standard graph. A standard graph was made by measuring the absorbance of varied concentrations of seratrodast (2–16 mg/L) in water/methanol (9:1) solution using a UV-2500 spectrophotometer at 268 nm. The calibrated plot showed a good correlation coefficient (y = 0.04997x + 0.00459, R2 = 0.9991). After forming the title salt, the solubility of seratrodast was found to be greatly improved.

7. Refinement

Crystal data, data collection and structure refinement details are summarized in Table 2[link]. The C-bound H atoms were positioned geometrically and refined as riding atoms: C—H = 0.95–1.00 Å with Uiso(H) = 1.2Ueq(C). The OH and NH3+ H atoms were located in difference Fourier maps and refined as riding atoms with Uiso(H) = 1.2Ueq(O,N).

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

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
