When acyclovir, denoted ACV, was converted into tricyclic acyclovir, TACV {3-[(2-hydroxyethoxy)methyl]-6-methyl-3H-imidazolo[1,2-a]purin-9(5H)-one}, it was expected to be inactive since the NH2 group at C2 of ACV was blocked by the closure of the third ring (Boryski et al., 1988). However, TACV exhibits a marked antiherpetic activity, with potent and selective activity against herpes simplex virus types 1 and 2, varicella-zoster virus and cytomegalovirus, and at the same time lower cytotoxicity (Boryski et al., 1991; Balzarini et al., 2002). The structure of TACV has been reported previously in a study aimed at improved understanding of the nature of the solvation and the relationships between the structure and thermodynamic parameters (Suwińska et al., 2001). Our interest was piqued by the observation that the structure contained an infinite zigzag chain of strong O···O contacts with an average O···O distance of 2.72 Å, passing through the (H2O)8 water clusters identified in the previous report. This chain is analogous to the one-dimensional zigzag water chain (average O···O = 2.78 Å) reported and studied (Cheruzel et al., 2003) as a potential model for biologically relevant proton wires. The zigzag structure is the second probable proton-wire structure proposed by Nagle & Morowitz (1978).
The previous structural parameters and structure-factor data for SX1107 were obtained from the IUCr electronic archives (Suwińska et al., 2001). The previously reported synthesis was described by Boryski et al. (1988) and Golankiewicz et al. (1991), with recrystallization from aqueous solution to produce colourless crystals of TACV.2H2O.
Crystal data, data collection and structure refinement details are summarized in Table 1. The CIF for the previous refinement contains two complete TACV molecules and four water molecules in the asymmetric unit. Molecule B has atoms O16B and C17B as the major component and atoms O16C and C17C as the minor component of a 75:25 disorder model. The published structure includes the minor component H atoms only on C17B and C17C. Minor-component H atoms on C15B and C18B were not included and the corresponding major-component H atoms were assigned full occupancy factors. Full-matrix least-squares refinement was initiated from the previous model non-H positions.
The disorder model was extended to include alternate positions for C18B/C and all the minor- and major-component disordered H atoms. Atomic displacement parameters were constrained to be equivalent between components B and C using EADP instructions [Please express in non-software specific terms]. Bond distances for the side chains were held similar in all three components using SADI instructions [Please express in non-software specific terms]. The positions of all the H atoms, including the disordered H atoms, were located from electron-density difference Fourier maps. The water atoms H1WB/C on O1W and the disordered hydroxy atoms H19B/C were modelled as simple statistical disorders. The positions of all the water H atoms were allowed to refine, with bond distances held similar using SADI instructions [Please express in non-software specific terms]. The positions of the hydroxy H atoms were modelled as a freely rotating group (H19A) or as riding atoms (H19B/C), with constraints of a tetrahedral bond angle and O—H = 0.82 Å. Methyl and methylene H atoms were refined as riding atoms in idealized tetrahedral positions, with C—H = 0.96 and 0.97 Å, respectively; methyl groups were allowed to rotate freely. The remaining H atoms were allowed to ride in idealized trigonal geometry, with C—H = 0.93 Å or N—H = 0.86 Å. Non-H atoms were assumed to vibrate anisotropically and H-atom isotropic displacement parameters were constrained to be a multiple of the equivalent displacement parameter of the atom they are bonded to (1.5Ueq for methyl and O-bound H atoms, and 1.2Ueq for other H atoms). The occupancy of the disorder in the side chain of molecule B refined to 0.746 (2):0.262.
TACV crystallizes as the water disolvate, (I), with Z' = 2. The independent units of the structure are shown in Fig. 1. The original report of the TACV structure included two disordered regions. Firstly, one H atom of one water molecule in an (H2O)8 cluster, located near an inversion centre, is statistically disordered, and secondly the ether O atom in concert with the adjacent methylene C atom of molecule B occupies two positions in a 0.75:0.25 ratio.
The molecular geometry of TACV, including the conformations of the side chains and the planarity of the delocalized fused-ring system, was discussed and compared with the molecular geometry of ACV; there were no surprising features. Hydrogen bonding, linking eight water molecules into the cluster noted above and linking the TACV molecules into infinite ABAB-type chains via N3A—H3A···N12B [2.803 (2) Å] and N3B—H3B···O11A [2.749 (2) Å] hydrogen bonds with a water-mediated link supporting the BA portions [O2W—H2WA···N12A = 2.793 (3) Å and O2W—H2WB···N7B = 2.983 (2) Å], was also described. Not noted was the near coplanarity of the crystallographically independent A and B ring systems as connected by this R33(11) motif (Etter et al., 1990). The r.m.s. deviations of the fitted atoms for the 12-atom planes are 0.021 and 0.007 Å for ring systems A and B, respectively, and only 0.058 Å for the fit to the combined 24 atoms (positions as in the CIF file). The interplanar angle between the A and B ring systems is 4.43 (7)°. The chains (pseudo ribbons) form face-to-face stacks in the ab direction (Fig. 2), with contacts ranging from 3.183 (3) Å [to upper limit of?] between inversion-related C9/C10═O11/N12 edge contacts for B. Numerous other contacts in the range 3.2–3.4 Å to the tops and bottoms of both rings are in the expected range for aromatic ring contacts, as discussed previously (Haller et al., 1979). The stacked aromatic ribbon layers (the region from about 0.2 to 0.8 along c) alternate with layers containing the TACV side chains and the water molecules (Fig. 2).
When analysing the O···O interactions in the previous report we discovered a one-dimensional chain involving alternating water–water and hydroxy–hydroxy O atoms. A difficulty was that there were no hydroxy H atoms connecting atom O19B to the water molecules, and only half an H atom from O1W connecting to the hydroxy O atom. Furthermore, the distance between inversion-related atoms H19B was 1.55 Å, too short to be real (Steiner, 2002). The solution was simple: a difference Fourier map revealed the alternate H-atom position between atoms O19B and O1W, thus defining a one-dimensional chain propagating parallel to a through y = 1/2, z = 0, displaying an unusual disorder of an elaborate concerted unit containing pair-wise alternating TACV molecules and water molecules across the inversion centres. The concerted placement of H atoms for one of the half-occupied chains is illustrated in Fig. 3(a). The inversion centres between O1W—O1W [symmetry code?] and O19B—O19B [symmetry code?] generate the second half-occupied one-dimensional chain, as illustrated in Fig. 3(b). The two chains have coincident O atoms and differ only in the concerted placement of the H atoms, which are bound to the right of the O atoms in Fig. 3(a) and to the left of the O atoms in Fig. 3(b). Similar disordered one-dimensional water chains stabilized by imidazole channels have been suggested for models of biologically relevant proton wires (Pomès & Roux, 2002; Cheruzel et al., 2003), in which protons may hop along a single-file chain of water molecules in a de Grotthuss relay mechanism (de Grotthuss, 1806; Cukierman, 2006).
The water molecules form an (H2O)8 cluster, located on an inversion centre at (1/2, 1/2, 0), consisting of a six-molecule hydrogen-bonded chain (horizontal in Fig. 4) with two additional water molecules hydrogen-bonded to the second and fifth molecules. The chain orients more or less parallel to c and each end of the chain acts as an acceptor for a hydrogen bond from molecule A [O19A—H19A···O3W = 2.740 (3) Å] and as a donor to molecule B [O3W—H3WB···O11B = 2.824 (3) Å]. Perpendicular to the chain, atom O2W donates to molecules A [O2W—H2WA···N12A = 2.793 (3) Å] and B [O2W—H2WB···N7B = 2.983 (2) Å]. Thus, both crystallographically independent TACV molecules participate via strong O—H···O water–water and water–drug interactions, and via O—H···N water–drug interactions, in a two-dimensional sheet structure for which the H-atom disorder is irrelevant. The one-dimensional concerted disorder water chain intersects the cluster plane at an angle, as illustrated in Fig. 4, creating the extensively hydrogen-bonded three-dimensional supramolecular network.

Experimental. The data set was obtained from the IUCr electronic archives (Reference: SX1107). The data as obtained contained only independent reflections so no value for Rint is given. The data yield near the limiting 2θ value of 30.0° in the original report was near 10%. Reducing the limiting 2θ value to 28.3° did not significantly change any refined parameter, but did greatly improve the analysis of variance. The data yield near the limit 2θ = 28.3° is 24%. The data/variable ratio is 16.4 and the observed data/variable ratio is 9.4 for 2θmax = 28.3°. |
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. |
