4-{5-[(2-Bromobenzyl)sulfanyl]-1H-tetrazol-1-yl}benzoic acid

Abstract top

In the title compound, C15H11BrN4O2S, the tetrazole ring makes dihedral angles of 45.97 (10) and 75.41 (1)°, respectively, with the benzoyl and bromobenzene rings while the dihedral angle between the benzene rings is 73.77 (1)°. In the crystal, molecules are linked through O-H... N and C-H... O hydrogen bonds, giving infinite chains in both the [110] and [1-10] directions. These chains are further connected by C-Br...[pi] and C-O...[pi] interactions and also by [pi]-[pi] stacking between tetrazole rings [centroid-centroid distance = 3.312 (1) Å], generating a three-dimensional network.

Comment top

The title acid is a screening molecule available in the ZINC database (Irwin et al., 2012) among the 'drugs-now' subset. This molecule has been identified as a PPAR gamma ligand candidate in a virtual screening study. The Peroxisome Proliferator-Activated Receptor, isoform gamma, is a transcription factor that regulates the expression of genes involved in glucose and lipid metabolism (Nolte et al., 1998). Our group recently described the crystal structure of a similar compound, evaluated as a PPARgligand in a competition assay (Mafud et al., 2013). Since tetrazoles are already known to have glucose lowering effects in vivo (Kees et al., 1989), in this virtual screening we chose some different representative molecules to evaluate the affinities and the extent of receptor activation. Here, we report the crystal structure of the title compound.

The dihedral angles between the tetrazole and the benzoyl and the bromo benzene rings are 45.97 (10)° and 75.41 (1)° respectively, while between the two benzene rings is 73.77 (1)°. The crystal packing is established through interactions of three types (Table 1):

The first one are intermolecular hydrogen bonds: O2—H1···N4(ii) and C9—H9···O1(i), with symmetry codes: (i)1+ x, -1 + y, z and (ii) -1+x, 1+y, z

The second one are C–X···π interactions: C1—O1 ··· Cg1(iii), 3.619 (2) Å and C11—Br1 ··· Cg2(iv), 3.581 (2) Å, where Cg1 and Cg2 are the centroids of the {N1, N2, N3, N4, C8} and {C10, C11, C12, C13, C14, C15} rings, respectively, with symmetry codes: (iii) x, 1 + y, z; (iv) 1/2 - x,-1/2 + y,1/2 - z.

And the last type is π-π stacking between centrosymmetric tetrazole neighbour rings (centroid-centroid distance=3.312 (1) Å )

Experimental top

A colourless single-crystal of the title compound was selected from the sample as supplied (Pharmeks Ltd.) without recrystallization.

Refinement top

The hydroxyl H atom was located in a difference Fourier map and refined with Uiso(H) = 1.5Ueq(O). The C-bound H atoms were included in calculated positions and treated as riding atoms: C—H = 0.93 and 0.97 Å, for CH and CH2 respectively, with Uiso(H) = 1.2Ueq(C).

Special details top

Experimental. Absorption correction: interpolation using Int.Tab. Vol. C (1992) p. 523,Tab. 6.3.3.3 for values of muR in the range 0-2.5, and Int.Tab. Vol.II (1959) p.302; Table 5.3.6 B for muR in the range 2.6-10.0. The interpolation procedure of (Dwiggins, 1975) is used with some modification

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.
