3,7-Dichloro-quinoline-8-carboxylic acid.

ABSTRACT: THE TITLE COMPOUND (TRADE NAME: quinclorac), C(10)H(5)Cl(2)NO(2), was crystallized from a dimethyl sulfoxide solution. Quinclorac mol-ecules are packed mainly via ?-? stacking inter-actions between neighbouring heterocycles (interplanar distance: 3.31?Å) and via O-H?N hydrogen bonding.

Ethyl 3,7-dichloro-quinoline-8-carboxyl-ate.

Project description:The title compound, C(12)H(9)Cl(2)NO(2), was prepared by the esterification of 3,7-dichloro-quinoline-8-carboxylic acid with triethyl phosphite. The crystal structure is stabilized by aromatic ?-? stacking between the benzene and the pyridine rings of neighbouring mol-ecules [centroid-centroid distances = 3.716?(2) and 3.642?(2)?Å]. In addition, weak inter-molecular C-H?N hydrogen bonds are present in the structure.

Diaqua-bis(3,7-dichloro-quinoline-8-carboxyl-ato)zinc(II) monohydrate.

Project description:In the title compound, [Zn(C(10)H(4)Cl(2)NO(2))(2)(H(2)O)(2)]·H(2)O, the Zn atom has a distorted square-pyramidal geometry comprising two O atoms and one N atom from two distinct 3,7-dichloro-quinoline-8-carboxyl-ate ligands, and two water mol-ecules. The free water mol-ecules are involved in inter-molecular O-H?O hydrogen bonding with the coordinated water mol-ecules and carboxyl-ate O atoms, to give a one-dimensional helical chain along the [100] direction.

catena-Poly[cobalt(II)-bis-(?-3,7-dichloro-quinoline-8-carboxyl-ato-?N,O:O')].

Project description:In the crystal structure of the title compound, [Co(C(10)H(4)Cl(2)NO(2))(2)](n), the Co(II) cation lies on a twofold rotation axis. Each cation is N,O-chelated by the carboxyl-ate anions of two 3,7-dichloro-quinoline-8-carboxyl-ate ligands. The second carboxyl-ate O atom of each ligand coordinates to the Co(II) cation of an adjacent mol-ecule, linking the cations into a linear chain. Strong inter-chain ?-? stacking inter-actions are observed in the crystal structure (perpendicular distance 3.42?Å, centroid-to-centroid distance 3.874?Å).

2-Chloro-quinoline-3-carboxylic acid.

Project description:The crystal structure of the title compound, C(10)H(6)ClNO(2), can be described by two types of crossed layers which are parallel to (110) and (10). The crystal packing is stabilized by inter-molecular C-H?O and O-H?N hydrogen bonds, resulting in the formation of a two-dimensional network and reinforcing the cohesion of the structure.

2,4-Dichloro-quinoline.

Project description:The asymmetric unit of the title compound, C(9)H(5)Cl(2)N, consists of two crystallographically independent mol-ecules. In both mol-ecules the quinoline ring system is essentially planar [maximum deviations from the best plane of 0.0232?(13) 0.0089?(15)?Å]. The angle between these planes is 22.40?(3)°. Conformers A and B are arranged face-to-face along the c axis, forming alternating pairs in the order AABB. The inter-planar distances AA, AB and BB are 3.3166?(11), 3.2771?(11) and 3.3935?(11)?Å, respectively. The crystal packing is stabilized by weak C-H?Cl and C-H?N inter-actions.

4,7-Dichloro-quinoline.

Project description:The two mol-ecules in the asymmetric unit of the title compound, C(9)H(5)Cl(2)N, are both essentially planar (r.m.s. deviations for all non-H atoms = 0.014 and 0.026?Å). There are no close C-H?Cl contacts.

(Benzoato-?O,O')(quinoline-2-carboxyl-ato-?N,O)(quinoline-2-carboxylic acid-?N,O)manganese(II).

Project description:The crystal structure of the title compound, [Mn(C(7)H(5)O(2))(C(10)H(6)NO(2))(C(10)H(7)NO(2))], contains manganese(II) ions six-coordinated in a distorted octa-hedral environment. The equatorial plane is occupied by four O atoms, two from the carboxyl-ate group of the benzoate ion, the other two from carboxyl-ate/carboxyl groups of the quinaldate/quinaldic acid mol-ecules. The axial positions are occupied by the N atoms of the quinoline ring systems. The metal ion lies on a twofold rotation axis that bisects the benzoate ligand; the quinaldate and quinaldic acid ligands are therefore equivalent by symmetry, and the carboxylate/carboxyl groups are disordered. The complexes are joined together by hydrogen bonds between the carboxyl-ate/carboxyl groups of adjacent quinaldate/quinaldic acid mol-ecules, forming zigzag chains that run along the c axis.

(Benzoato-?O,O')(quinoline-2-carboxyl-ato-?N,O)(quinoline-2-carboxylic acid-?N,O)copper(II).

Project description:The crystal structure of the title compound, [Cu(C(10)H(6)NO(2))(C(7)H(5)O(2))(C(10)H(7)NO(2))], contains copper(II) ions five-coordinated in a distorted trigonal-bipyramidal environment. The equatorial plane is occupied by three O atoms, one from the carboxyl-ate group of the benzoate ion considered as occupying a single coordination site, the other two from two carboxyl-ate groups of the quinaldic acid and quinaldate ligands. The axial positions are occupied by the N atoms of the quinoline ring system. The metal ion lies on a twofold axis that bisects the benzoate ion. The quinaldate and quinaldic acid ligands are equivalent by symmetry, and the carboxyl-ate/carboxyl groups are disordered. The disordered H atom is shared between the carboxyl-ate groups of adjacent quinaldic acid mol-ecules. Such hydrogen bonds delineate zigzag chains that run along the c axis. The structure is very similar to that of the Mn(II) analog.

Design, Synthesis and Antibacterial Evaluation of Some New 2-Phenyl-quinoline-4-carboxylic Acid Derivatives.

Project description:A series of new 2-phenyl-quinoline-4-carboxylic acid derivatives was synthesized starting from aniline, 2-nitrobenzaldehyde, pyruvic acid followed by Doebner reaction, amidation, reduction, acylation and amination. All of the newly-synthesized compounds were characterized by ¹H-NMR, (13)C-NMR and HRMS. The antibacterial activities of these compounds against Gram-negative (Escherichia coli, Pseudomonas aeruginosa) and Gram-positive bacteria (Staphylococcus aureus, Bacillus subtilis), as well as one strain of methicillin-resistant Staphylococcus aureus (MRSA) bacteria were evaluated by the agar diffusion method (zone of inhibition) and a broth dilution method (minimum inhibitory concentration (MIC)), and their structure-activity relationships were obtained and discussed. The results revealed that some compounds displayed good antibacterial activity against Staphylococcus aureus, and Compounds 5a₄ and 5a₇ showed the best inhibition with an MIC value of 64 μg/mL against Staphylococcus aureus and with an MIC value of 128 μg/mL against Escherichia coli, respectively. The results of the MTT assay illustrated the low cytotoxicity of Compound 5a4.
