In the title compound, C₂₅H₂₅NO₅S, which exhibits metabolism-regulating activity, the 1,4-dihydropyridine ring adopts a flattened boat conformation while the cyclohexenone ring is in an envelope conformation. Molecules in the crystal are assembled into C(6) chains along the a-axis direction via N—H⋯O hydrogen bonds. The thienyl fragment is disordered over two sets of sites in a 0.7220 (19):0.2780 (19) ratio.

Keywords: crystal structure; 1,4-dihydropyridine; metabolic activity; disorder.

1. Chemical context

Up to now, the 2-methyl-5-oxo-1,4,5,6,7,8-hexahydroquinoline-3-carboxylic esters in the class of condensed 1,4-dihydropyridine (DHP) derivatives have been relatively poorly studied. Monocyclic DHPs are very commonly known as cardiovascular regulating and hypotensive compounds (Swarnalatha et al., 2011 ). The title compound is an original substance with a specific ligand effect on the metabolism-regulating free fatty acid receptor 3 (FFAR3 or GPR41). At the same time, it does not act on other metabolite-sensing receptors such as FFAR2 (GPR43) or the hydroxycarboxylic receptor 2 (HCA2) having similar pharmacological effects.

2. Structural commentary

Fig. 1 shows the molecular structure of the title compound. A two-component disorder is found for the thienyl fragment, which assumes two orientations differing by a 180° rotation around the C7—C16 bond. The major component has a refined occupancy of 0.7220 (19) and is that shown in Fig. 1. The 1,4-dihydropyridine ring adopts a flattened boat conformation while the cyclohexenone ring is in an envelope conformation. Atoms C7 and N1 deviate by 0.298 (3) and 0.135 (3) Å, respectively, in the same direction from the mean C6/C8/C9/C10 plane. The fused cyclohexene ring has an envelope conformation, with atom C13 out of the C8/C9/C12/C14/C15 plane by 0.628 (3) Å. The thienyl ring is almost perpendicular to the C6/C8/C9/C10 plane, subtending a dihedral angle of 82.50 (8)°.

3. Supramolecular features

In the crystal, intermolecular N—H⋯O hydrogen bonds (Table 1) assemble the molecules into chains along the a-axis direction (Fig. 2). The hydrogen-bonding pattern in the structure can be described by a C(6) graph-set motif. If one denotes the thienyl fragment as the `head' of the molecule and an ethoxy group as the `tail', then the crystal structure can be described as consisting of head-to-head and tail-to-tail molecular assemblies, or layers, parallel to the ac plane and stabilized by van der Waals interactions (Fig. 2).

4. Database survey

A search of the Cambridge Structural Database (CSD Version 5.39, last update February 2018; Groom et al., 2016 ) for the 2-methyl-5-oxo-1,4,5,6,7,8-hexahydroquinoline-3-carboxylic acid fragment gave nine hits: BEZWEK (Kidwai et al., 2012 ), FERHEQ (Carroll et al., 2004 ), HALLUE (Huang et al., 2016 ), JOXTOF (Rose & Dräger, 1992 ), LAVWIP (Yu et al., 2005 ), RAQROT (Meng et al., 2017 ), SUYWIT (Natarajan et al., 2010 ), VUZRIS (Yang et al., 2010 ) and YIYDUH (Gein et al., 2014 ). Unlike the title compound, which has a thienyl group at position 4 of the 1,4-dihydropyridine ring, the most closely related structures found in the CSD have phenyl derivatives exclusively at this position. In all of the selected structures, the 1,4-dihydropyridine ring also assumes a boat conformation of different depths. Deviations from the mean plane of the four basal atoms range from 0.067 (3) to 0.168 (2) Å for the N atom and 0.177 (4) to 0.399 (2) Å for C atoms. The dihedral angles between the planar substituents on the 1,4-dihydropyridine ring and its mean plane are close to 90°. The only exception is LAVWIP with an angle of 83.62 (8)°. Seven of the nine listed crystal structures analogous to the title compound have intermolecular N—H⋯O-type hydrogen-bonding motifs.

5. Metabolic activity

The title compound possesses considerable and specific activity as a ligand of FFAR3. At 50 µM concentration, the compound inhibits forskolin-stimulated level of cAMP by 60% in recombinant cells expressing FFAR3. The compound through FFAR3 inhibits the cAMP-dependent pathway by inhibiting adenylate cyclase activity and decreasing the production of cAMP, which results in decreased activity of cAMP-dependent protein kinase. The activation of FFAR3 could be involved in the production of leptin by adipose tissue, regulation of intestinal immunity and secretion of the PYY peptide and GLP-1 hormone by enteroendocrine cells (Ichimura et al., 2014 ).

6. Synthesis and crystallization

4-(Thien-2-yl)-2-methyl-5-oxo-1,4,5,6,7,8-hexahydroquinoline-3-carboxylic acid ethoxycarbonylphenylmethylester 1 was synthesized according to the scheme in Fig. 3 as follows. A solution of 1.12 g (10 mmol) of thiophene-2-carbaldehyde 3, 2.64 g (10 mmol) of 3-oxobutyric acid 4 and 2.3 g (30 mmol) of ammonium acetate in 15 mL of ethanol was stirred at room temperature. After 10 min, 1.12 g (10 mmol) of cyclohexane-1,3-dione 2 and 10 drops of acetic acid were added. The reaction mixture was stirred overnight and the resulting precipitate was filtered off and washed with 50% ethanol. After crystallization from ethanol, 2.5 g (55.4%) of compound 1 was obtained. m.p. 494–496 K. ¹H NMR (400 MHz, CDCl₃) δ, ppm: 1.13 (3H, t, J = 7.0 Hz, CH₃), 1.88–2.00 (2H, m, CH₂), 2.24–2.36 (2H, m, CH₂), 2.37 (3H, s, CH₃), 2.38–2.48 (2H, m, CH₂), 3.95–4.23 (2H, m, CH₂), 5.47 (1H, s, CH), 5.88 (1H, s, CH), 6.39 (1H, s, NH), 6.86 (1H, dd, J = 5.1, 3.5 Hz, H^Th), 6.96 (1H, dt, J = 3.6, 1.0 Hz, H^Th), 7.04 (1H, dd, J = 5.1, 1.3 Hz, H^Th), 7.30–7.35 (3H, m, 3 H^Ar), 7.36–7.42 (2H, m, 2 H^Ar). LC–MS (ESI), m/z: 450 ([M − H]⁻, 100%). Analysis calculated for C₂₅H₂₅NO₅S: C, 66.50; H, 5.58; N, 3.10. Found C, 66.23; H, 5.70; N, 3.00.

7. Refinement

Crystal data, data collection and structure refinement details are summarized in Table 2. All hydrogen atoms bonded to carbon atoms were placed in calculated positions and included as riding contributions in the final stages of refinement [Csp³—H = 0.95–1.00 Å with U_iso(H) = 1.2U_eq(C) for methine and methylene groups, and U_iso(H) = 1.5U_eq(C) for methyl groups]. The hydrogen atom bonded to the nitrogen atom was identified as the strongest peak in the electron-density difference map and was refined isotropically. There is a two-component disorder in the thienyl group with the ring assuming two positions with opposite orientations. The two orientations were refined as rigid groups using an accurate determination of the geometry of the thienyl group taken from CSD structure UWIYUW (Anil et al., 2016 ) as the model. Refinement of the group occupation factor (the second free variable in the FVAR instruction of SHELXL) gave the value of 0.7220 (19).

Special details top

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.
