Dimethyl biphenyl-4,4′-dicarboxylate
The asymmetric unit of the title compound, C(16)H(14)O(4), consists of one half-mol-ecule of an essentially planar biphenyl-dicarboxylic acid ester, with the complete molecule generated by an inversion centre. The maximum deviation from a least-squares plane through all non-H atoms occurs for the peripheric methyl groups and amounts to 0.124 (2) Å. The solid represents a typical mol-ecular crys...
متن کاملDimethyl 2,6,8-trimethyl-1,2-dihydroquinoline-2,4-dicarboxylate
The title compound, C(16)H(19)NO(4), the hydrogenated ring adopts a twisted conformation. In the crystal, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric R(2) (2)(10) dimers. These dimers are further connected via inter-molecular N-H⋯O hydrogen bonds, forming infinite double chains along [001].
متن کاملDesign and Hepatoprotective Evaluation of Biphenyl Dimethyl Dicarboxylate (DDB) and Silymarin Solid Dispersion and Self-Micro Emulsifying Drug Delivery Systems
Biphenyl Dimethyl Dicarboxylate (DDB) and Silymarin are widely used drugs for the treatment of hepatitis C virus, have poor bioavailability due to their low aqueous solubility that limits their dissolution rates. To overcome these limitations solid dispersions (SDs) and self-microemulsifing drug delivery systems (SMEDDS) were prepared in an attempt to improve their release profile. SDs were pre...

In the title compound, C(22)H(16)O(4), the 7-phenyl ring is inclined at dihedral angles of 36.73 (9) and 69.37 (9)° with respect to the biphenyl benzene rings. The two benzene rings of the biphenyl unit form a dihedral angle of 55.99 (8)°. There are no significant hydrogen bonds observed in the crystal of this compound.
متن کامل1-(2-Bromophenyl)ethane-1,2-diyl 1,1′-biphenyl-2,2′-dicarboxylate
In the title compound, C(22)H(15)BrO(4), the bromo-benzene ring is inclined at dihedral angles of 23.87 (11) and 52.37 (11)° with respect to the planes of the two benzene rings. The two benzene rings of the biphenyl unit form a dihedral angle of 49.08 (11)°. In the crystal, mol-ecules are linked into [100] chains by C-H⋯O hydrogen bonds.
