The title compound, C₅₆H₈₃N₉O₉S·3CH₃OH, is a methanol trisolvate of the cyclolinopeptide cyclo(Met¹—Leu²—Ile³—Pro⁴—Pro⁵—Phe⁶—Phe⁷—Val⁸—Ile⁹) (henceforth referred to as CLP-B), which was isolated from flaxseed oil. All the amino acid residues are in an L-configuration based on the CORN rule. The cyclic nonapeptide exhibits eight trans peptide bonds and one cis peptide bond observed between the two proline residues. The conformation is stabilized by an α-turn and two consecutive β-turns each containing a N—H⋯O hydrogen bond between the carbonyl group O atom of the first residue and the amide group H atom of the fourth (α-turn) or the third residue (β-turns), repectively. In the crystal, the components of the structure are linked by N—H⋯O and O—H⋯O hydrogen bonds into chains parallel to the a axis.

Comment top

Flaxseed (bionamial name: Linum usitatassimum) contains mostly triglyceride oil (omega-3 fatty acids, and alpha-linolenic acid etc.), to lesser amounts lignans and very small amounts of hydrophobic cyclolinopeptides. These cyclo octa-and nonapeptides have attracted significant interest because of their various biological activities, most importantly because of their immuno-suppressive activity (Wieczorek et al., 1991), their cytoprotective ability, their inhibitory activity toward calcium-dependent activation of T-lymphocyte cell division (Gaymes et al., 1997), and their biomolecular interaction with human albumin (Rempel et al., 2010). The structures of nine different cyclolinopeptides (CLP-A to CLP-I) have been elucidated by two-dimensional FT-NMR spectroscopy (Matsumoto et al., 2002; Morita et al., 1999; Matsumoto et al., 2001). Structure determinations of CLP-A with different co-crystallized solvent molecules have been established by single-crystal X-ray diffraction (Di Blasio et al., 1987, 1989; Matsumoto et al., 2002; Quail et al. 2009). Recently, the crystal structure of the previously unknown CLP-K has been reported (Jadhav et al., 2011). The crystal structure of cyclo(Met¹—Leu²—Ile³—Pro⁴—Pro⁵—Phe⁶—Phe⁷—Val⁸—Ile⁹), CLP-B, was determined as part of our ongoing research on the biological activity of flaxseeds from different locations and strains.

All the amino acid residues in CLP-B are in the L configuration based on CORN rule. The L configuration of the amino acid residues in the CLP-B was determined previously using derivative chemistry (Morita et al., 1999). Applying the Cahn-Ingold-Prelog priority rules (Cahn et al., 1966), the configuration at the chiral α-C atom of each amino acid residue is S. The standard uncertainty u = 0.07 at the Flack parameter x = 0.09 implies an enantiopure-sufficient inversion-distinguishing power and together with |x| < 2u one can conclude that the absolute structure is correct (Flack & Bernardinelli, 2000). The cyclolinopeptide exhibits eight trans peptide bonds with values for ω ranging from 162.8 (2) to 177.1 (2)° (see Table 2) and one cis peptide bond observed between the two proline residues (ω = -9.8 (3)°) (see Table 2). The conformation of the cylic peptide is stabilized by an α-turn and two consecutive β-turns each containing a hydrogen bond between the carbonyl oxygen of the first residue and the amide hydrogen of the fourth (α-turn) or the third residue (β-turn), repectively. The 5→1 NH···O=C contact bond (α-turn) involves the amide group of Phe⁷ and carbonyl group of Ile³ with the two cis bonded proline residues Pro⁴ and Pro⁵ being part of this α-turn. The α-turn in CLP-B is identical to the one found in CLP-K (Jadhav et al., 2011). In contrast, only one β-turn was located in the crystal structure of CLP-K, which involved the amide group of Ile³ and carbonyl group of Ile⁹ (Jadhav et al., 2011). The first β-turn, a 4→1 NH···O=C contact bond, is formed between the amide group of Leu² and the carbonyl group of Val⁸. The second β-turn is observed between the amide group of Met¹ and the carbonyl group of Phe⁷. The presence of these turns leads to a very twisted conformation of CLP-B with an almost V-shaped part at Pro⁵ as depicted in Fig. 2. The side chains of Met¹, Leu², Ile³, Phe⁶, Phe⁷, Val⁸, Ile⁹ all adopt the gauche(+) conformation based on their χ₁ torsion angles (see Table 2).

The analysis of the conformation of CLP-B in the polar solvent d₆-DMSO using NMR spectroscopy showed the presence of a γ-turn, 3→1 NH···O═C contact bond, involving the amide group of Val⁸ and carbonyl group of Phe⁶ (Matsumoto et al., 2002). In contrast, this γ-turn is not observed in the solid state structure of CLP-B. In fact, the nitrogen atom of the amide group in Val⁸ and the oxygen atom of carbonyl group in Phe⁶ are separated by 3.670 (3) Å, which exceeds by far the N···O contact distance of 3.07 Å based on the sum of the van der Waals radii for nitrogen and oxygen. The value for the 3→1 NH···O=C contact bond was calculated to be 1.95 Å based on distance geometry (DG) calculations in combination with NMR data (Matsumoto et al., 2002). However, in the crystal structure of CLP-B this distance is 3.06 (3) Å, which is too long for a NH···O═C contact bond.

The CLP-B molecules are linked via intermolcular NH···O═C contact bonds. In addition, the CLP-B units are connected via one methanol solvent molecule through hydrogen bonds involving a) one carbonyl group of one peptide and the hydrogen atom of the hydroxy group of a methanol molecule and, b) the oxygen atom of the hydroxy group of the same methanol molecule and the hydrogen atoms of the two amide groups of a symmetry related CLP-B molecule (see Table 1). These hydrogen bond interconnections are responsible for the formation of infinite one-dimensional chains parallel to the a axis. The remaining two methanol solvent molecules form only one hydrogen bond with either a carbonyl group or an amide group of a symmetry related ClP-B molecule.

Experimental top

Crystals of CLP-B were obtained via slow cooling of a saturated solution of CLP-B in methanol. A clear solution of CLP-B (5 mg) in (100 µL) was obtained upon sonicating and heating the CLP-B/methanol solvent mixture to 323K. The solution was allowed to reach room temperature. Single small cube-like crystals of CLP-B, suitable for X-ray diffraction, were obtained within two hours.

Special details top

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.
