4,4'-Unsymmetrically substituted 3,3'-biphenyl alpha helical proteomimetics as potential coactivator binding inhibitors.

ABSTRACT: A series of unsymmetrically substituted biphenyl compounds was designed as alpha helical proteomimetics with the aim of inhibiting the binding of coactivator proteins to the nuclear hormone receptor coactivator binding domain. These compounds were synthesized in good overall yields in seven steps starting from 2-bromoanisole. The final products were evaluated using cotransfection reporter gene assays and mammalian two-hybrid competitive inhibition assays to demonstrate their effectiveness as competitive binding inhibitors. The results from this study indicate that these proteomimetics possess the ability to inhibit coactivator-receptor interactions, but via a mixed mode of inhibition.

Synthesis of biphenyl proteomimetics as estrogen receptor-alpha coactivator binding inhibitors.

Project description:A novel series of biphenyl proteomimetic compounds were designed as estrogen receptor-alpha (ER(alpha)) coactivator binding inhibitors. Synthesis was accomplished through a convergent approach, employing Suzuki coupling chemistry to ligate the individual modular units. Initial biological results support the ability of these compounds to compete for the ER(alpha) coactivator binding groove.

Biphenyl-3,3',4,4'-tetra-amine.

Project description:The title compound, C(12)H(14)N(4), has a crystallographically imposed centre of symmetry. Inter-molecular N-H?N hydrogen bonds between amino groups link adjacent mol-ecules into a three-dimensional network where ten-membered hydrogen-bonded rings are observed.

Biphenyl-3,3',4,4'-tetra-carboxylic acid dihydrate.

Project description:The asymmetric unit of the title compound, C(16)H(10)O(8)·2H(2)O, contains one-half of the centrosymmetric organic mol-ecule and one water mol-ecule. The dihedral angles between the carboxyl-ate groups and the adjacent phenyl ring are 71.31?(3) and 16.67?(3)°, while the carboxyl-ate groups are oriented at a dihedral angle of 72.01?(3)°. In the crystal structure, inter-molecular O-H?O and bifurcated O-H?(O,O) hydrogen bonds link the mol-ecules to form a three-dimensional supra-molecular network.

3,3'-[Biphenyl-4,4'-diylbis(-oxy)]diphthalic acid.

Project description:In the title mol-ecule, C(28)H(18)O(10), the two central benzene rings form a dihedral angle of 31.0?(1)°. In the phthalic acid fragments, the carb-oxy groups in the meta positions are approximately coplanar with the attached benzene rings, being inclined to their planes at 2.7?(1) and 10.3?(1)°, while the carb-oxy groups in the ortho positions are twisted from the benzene ring planes by 83.5?(1) and 75.4?(1)°. In the crystal, O-H?O hydrogen bonds link the mol-ecules into layers parallel to the bc plane. Weak C-H?O hydrogen bonds and ?-? inter-actions between the aromatic rings [centroid-centroid distance = 3.7674?(3)?Å] further consolidate the crystal packing.

3,3'-Dichloro-biphenyl-4,4'-diaminium sulfate.

Project description:In the title compound, C(12)H(12)Cl(2)N(2) (2+)·SO(4) (2-), the two rings are not coplanar [dihedral angle = 48.7?(2)°]. In the crystal, multiple N-H?O hydrogen-bond inter-actions are found between the ammonium and sulfate groups.

Hexaaqua-cobalt(II) 3,3'-dicarb-oxy-biphenyl-4,4'-dicarboxyl-ate.

Project description:In the crystal structure of the title compound, [Co(H(2)O)(6)](C(16)H(8)O(8)), both the cation and anion are centrosymmetric. The Co cation displays a CoO(6) octa-hedral geometry formed by six water mol-ecules. In the anion, the two carboxyl groups are oriented at dihedral angles of 4.8?(5) and 10.4?(7)° with respect to the benzene ring. Very strong O-H?O hydrogen bonds between the protonated and deprotonated carboxylate groups occur. Neighbouring cations and anions are connected through O-H?O hydrogen bonds into a three-dimensional supra-molecular structure.

Dimethyl 3,3'-di-meth-oxy-biphenyl-4,4'-di-carboxyl-ate.

Project description:In the title compound, C18H18O6, the biphenyl moiety is twisted with a dihedral angle of 29.11 (10)°. The carbometh-oxy groups form C-C-C-O torsion angles of -18.3 (3) and -27.7 (3)° with the attached rings, as a result of steric hindrances from the nearby meth-oxy groups. In the absence of stacking inter-actions and with no H⋯O contacts shorter than 2.7 Å, the packing is dominated by weaker van der Waals inter-actions.

N,N'-Bis(4-chloro-benzyl-idene)-3,3'-dimeth-oxy-biphenyl-4,4'-diamine.

Project description:The title compound, C(28)H(22)Cl(2)N(2)O(2), crystallized with two independent mol-ecules (A and B) in the asymmetric unit. The two mol-ecules differ essentially in the orientation of the outer aromatic rings. These dihedral angles are 56.07?(13) and 27.62?(15)?Å for mol-ecules A and B, respectively. In the crystal, A mol-ecules are related as centrosymmetric pairs through a weak ?-? inter-action [centroid-centroid distance = 3.6959?(15)?Å]. There are also a number of inter-molecular C-H?O, C-H?N and C-H?? inter-actions present.

Diaqua-bis(2,2'-biimidazole)cobalt(II) 4,4'-dicarboxy-biphenyl-3,3'-di-car-boxylate.

Project description:In the title compound, [Co(C(6)H(6)N(4))(2)(H(2)O)(2)](C(16)H(8)O(8)), the Co(II) cation and the organic anion occupy different crystallographic inversion centres and, as a consequence, the asymmetric unit comprises two half-mol-ecules. The benzene groups are coplanar. The four coordinating N atoms of the two bidentate biimidazole ligands define the equatorial plane of a slightly distorted octa-hedral CoO(2)N(4) geometry, and the water O atoms lie in the axial coordination sites. Translational (a,) and inversion-related symmetry operations link the Co complex mol-ecules and the negatively charged carboxyl-ate anions via inter-molecular N-H?O and O-H?O hydrogen bonds into sheets parallel to (01). The coordinated water mol-ecules connect the sheets through O-H?O hydrogen bonds, forming a three-dimensional framework. In addition, two intra-molecular O-H?O hydrogen bonds are observed between the carboxyl and carboxyl-ate groups.

Crystal structure of dimethyl 4,4'-di-meth-oxy-biphenyl-3,3'-di-carboxyl-ate.

Project description:In the title compound, C18H18O6, the benzene rings are coplanar due to the centrosymmetric nature of the mol-ecule, with an inversion centre located at the midpoint of the C-C bond between the two rings. Consequently, the methyl carboxyl-ate substituents are oriented in a trans fashion with regards to the bond between the benzene rings. The methyl carboxyl-ate and meth-oxy substituents are rotated slightly out of plane relative to their parent benzene rings, with dihedral and torsion angles of 18.52 (8) and -5.22 (15)°, respectively. The shortest O⋯H contact between neighbouring mol-ecules is about 2.5 Å. Although some structure-directing contributions from C-H⋯O hydrogen-bonding inter-actions are possible, the crystal packing seems primarily directed by weak van der Waals forces.
