Abstract

A peptide biphenyl hybrid compound {systematic name: dimethyl 2,2′-[((2S,2′S)-2,2′-{[(2S,2′S)-1,1′-([1,1′-biphen­yl]-2,2′-dicarbon­yl)bis­(pyrrolidine-1,2-diyl-2-carbon­yl)]bis­(aza­nedi­yl)}bis­(3-phenyl­propano­yl))bis­(aza­nedi­yl)](2S,2′S)-dipropionate hemihydrate}, C₅₀H₅₆N₆O₁₀·0.5H₂O, was prepared by coupling of [1,1′-biphen­yl]-2,2′-dicarbonyl dichloride, tri­ethyl­amine and the tripeptide Pro–Phe–Ala in CH₂Cl₂ at 273 K under an N₂ atmosphere. In the crystal, the asymmetric unit contains the peptide biphenyl hybrid accompanied by one-half of a water mol­ecule. A C atom of one of the proline rings is disordered between two positions in a 0.746 (11):0.254 (11) ratio. An important structural aspect of peptide compounds is their capacity to self-associate mediated by inter­molecular and intra­molecular hydrogen bonding. This characteristic can be useful in understanding the inter­actions between peptides and biomacromolecular targets, as well as to explain peptide properties.

Chemical context  

Peptides are combined linear chains of amino acids and are essential for all biological processes. Consequently, they are of great interest in the biomedical field, and research into the use of peptides and modified peptides as therapeutics is increasing rapidly. At present there are over 100 approved peptide-based therapeutics on the market, with the majority being smaller than 20 amino acids (Bruno et al., 2013 ▸ ). However, these peptides have some drawbacks: their poor absorption after oral ingestion, low diffusion in tissue organs, and low metabolic stability towards protease enzymes as well as undesired side-effects of flexible peptides due to inter­action with several receptors.

To overcome these disadvantages, researchers are aiming at the development of new treatment methods based on peptides and proteins, by introducing both structural and functional specific modifications and maintaining the features responsible for biological activity. The synthesis, structure, and properties of peptide–biphenyl hybrids I and II (Fig. 1 ▸), which are derivatives of 1,1-biphenyl with amino acids or peptide chains at the positions C2 and C2′ (Mann et al., 2002 ▸; Montero, Mann et al., 2004 ▸) have been studied intensively to overcome the disadvantages mentioned above.

Structure of peptide-biphenyl hybrids I and II.

The combination of biphenyl and peptide fragments provides compounds with structural (Mann et al., 2002 ▸) and biological properties of significant inter­est, as illustrated by the glycopeptide anti­biotic vancomycin, the proteasome inhibitor TMC-95A (Kaiser et al., 2004 ▸) and the peptide anti­biotic WS- 43708A (Rajamoorthi & Williams, 1987 ▸), aryl­omycins (Schimana et al., 2002 ▸) and biphenomycins (Ezaki et al., 1985 ▸). The inhibition of calpain I by biphenyl derivatives and peptide–biphenyl hybrids was reported by Montero, Albericio et al. (2004 ▸).

Biphenyl is a typical drug-like scaffold, which is present in 2.1% of reference drug mol­ecules (Bemis et al., 1996 ▸). Based on the important role of the biphenyl unit and peptides in biological activity, we report here the synthesis and crystallographic study of a peptide–2,2′-biphenyl hybrid with the tripeptide Pro–Phe–Ala (Fig. 2 ▸).

Structural commentary  

The title compound crystallizes in space group P2₁2₁2₁ with one mol­ecule of dimethyl 2,2′-[((2S,2′S)-2,2′-{[(2S,2′S)-1,1′-([1,1′-biphen­yl]-2,2′-dicarbon­yl)bis­(pyrrolidine-1,2-diyl-2-carbon­yl)]bis­(aza­nedi­yl)}bis­(3-phenyl­propano­yl))bis­(aza­ne­di­­yl)](2S,2′S)-dipropionate) and one-half of a water mol­ecule in the asymmetric unit (Fig. 2 ▸). One of the proline rings is disordered over two conformations and atom C17 was refined using a split model with occupancies of 0.746 (11) and 0.254 (11). An intra­molecular hydrogen bond is formed between the NH and CO groups of the two tripeptides with a distance of 2.04 Å (N5—H5⋯O5=C19, see Table 1 ▸, Fig. 2 ▸), which is slightly shorter than previously reported (Ranganathan et al., 1997 ▸). The C20–C25 and C26–C31 benzene rings are roughly perpendicular to each other, with a dihedral angle between them of 84.4 (4)°. An inter­esting feature is the non-coplanarity between each phenyl ring and the C=O function of the attached peptide bond. The C26—C31—C32=O6, C26—C31—C32—N4 and C25—C20—C19=O5, C25—C20—C19—N3 torsion angles are 59.8 (4)°, −123.0 (3)° and −85.9 (4)°, −96.8 (4)°, respectively. The torsion angles ω, Φ and Ψ along the two tripeptide backbones are given in Table 2 ▸. The torsion angles φ and ψ of amino acids Phe2, Pro4, Phe5 and Ala6 (as defined in Table 2 ▸) correspond with the α region in a Ramachandran plot, while for amino acids Pro1 and Ala3 the β region is observed.

Supra­molecular features  

The crystal packing is dominated by hydrogen bonding (Table 1 ▸). The water mol­ecule stabilizes the packing by bridging atoms O10 and O7 (hydrogen bonds O11—H11B⋯O10, O11—H11A⋯O7) and makes an additional hydrogen bond C29—H29⋯O11 with a neighbouring mol­ecule. The mol­ecules are further linked via a hydrogen bond between the NH and CO groups of peptide bonds (N2—H2⋯O3=C5), resulting in chains running in the a-axis direction (Fig. 3 ▸). In addition, five C–H⋯O=C inter­actions with H⋯O distances ranging from 2.41 to 2.67 Å are observed.

Database survey  

A search in the Cambridge Structural Database (CSD, Version 5.40, 2019.2; Groom et al., 2016 ▸) for a peptide–biphenyl hybrid with three amino acids gave no hits. We found nine structures of peptide–biphenyl hybrids containing one and two amino acids. In three of them a di­sulfide bridge is present. Three structures contain only one amino acid (MULLOU, Mann et al., 2002 ▸; WAFRUR and WAFSAY, Herradón et al., 2004 ▸) and two structures contain two amino acids (MULLUA, Mann et al., 2002 ▸; WAFSEC, Herradón et al., 2004 ▸). For the structures of MULLUA and WAFSEC, the torsion angles ϕ and ψ are located in different regions of the Ramachandran plot compared to the title structure.

Synthesis and crystallization  

To a round-bottom flask was added amine HN–proline–phenyl­alanine–alanine–COOMe (1 eq.), Et₃N (2 eq.) and anhydrous CH₂Cl₂ (50mL). To this solution was added a solution of (1,1′-biphen­yl)-2,2′-dicarbonyl dichloride in CH₂Cl₂ at 273 K under an N₂ atmosphere. After completion of the reaction, the mixture was washed with 1N HCl solution, water and a solution of brine, respectively. The organic phase was dried over Na₂SO₄, filtered and evaporated under reduced pressure. The crude product was then purified by flash chromatography (AcOEt/hexane 3:2) to give a yellow solid (63% yield). The compound was recrystallized by slow evaporation in methanol to give crystals suitable for X-ray diffraction.

Crystal data, data collection and structure refinement details are summarized in Table 3 ▸. All H atoms were positioned geometrically and treated as riding on their parent atoms with N—H = 0.88 Å and U _iso(H) = 1.2U _eq (N), C_aromatic—H = 0.95 Å and U _iso(H) = 1.2U _eq(C), C_{proline, methylen}—H = 0.99 Å and U _iso(H) = 1.2 U _eq(C), C_meth­yl—H = 0.98 Å and U _iso(H) = 1.5 U _eq(C), O_water—H = 0.87 Å and U _iso(H) = 1.52U _eq(O). A rotating group model (AFIX 137) was applied to the methyl groups at C1, C4, C48, C50. The solvent water mol­ecule is disordered and was refined with a site occupation factor fixed to 0.5. The ring of one of the proline residues shows two conformations with refined occupancy factors for atom C17 converging to 0.746 (11) and 0.254 (11).

Special details

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.
