In the title compound, C(23)H(15)Cl(2)NS, the quinoline system is almost planar [r.m.s. deviation = 0.013 (2) Å]. The phenyl group is disordered over two positions with site occupancies of 0.55 and 0.45, and is oriented in a nearly perpendicular configuration to the quinoline ring [the dihedral angles between the quinoline ring and the major and minor disordered components of the phenyl ring ar...

In the title compound, C(25)H(21)F(2)N(3)O(5), the pyrimidine and difluoro-benz-yloxy rings are twisted away from the central quinoline ring system, making dihedral angles of 54.6 (1) and 74.1 (1)°, respectively. A weak C-H⋯O inter-action links symmetry-related mol-ecules, forming a pseudo-dimer. π-π inter-actions between the quinoline rings of symmetry-related mol-ecules [centroid-centroid dis...

In the title Schiff base compound, C(20)H(18)N(4)O(4), the conformation along the bond sequence linking the benzene and quinoline rings is trans-(+)gauche-trans-trans-(+)gauche-trans-trans. The dihedral angle between the aromatic ring systems is 80.3 (6)°. In the crystal, a pair of inter-molecular N-H⋯N hydrogen bonds link the mol-ecules into centrosymmetric R(2) (2)(20) dimers, which are aggre...

The dinuclear title compound, [Pb(2)(C(10)H(6)NO(2))(2)(CH(3)COO)(2)(CH(3)OH)(2)], lies across an inversion center. The methanol-coordinated Pb(II) atom is chelated by the acetate anion as well as by the quinoline-2-carboxyl-ate anion. One O atom of the quinoline-2-carboxyl-ate anion bridges two symmetry-related Pb(II) atoms, forming the dinuclear compound. Aside from the six atoms connected to...

Ten 2-substituted quinoline alkaloids isolated from a plant used for treatment of New World cutaneous leishmaniasis have antileishmanial in vitro activities against the extracellular forms of Leishmania spp. BALB/c mice infected with Leishmania amazonensis PH8 or H-142 or Leishmania venezuelensis were treated 1 day after the parasitic infection with a quinoline alkaloid (100 mg/kg of body weigh...

The title compound, [Sr(C(10)H(6)NO(2))(2)(H(2)O)(2)](n), contains an eight-coordinate Sr(II) ion displaying a distorted square-anti-prismatic geometry, two quinoline-3-carboxyl-ate ligands and two terminal water mol-ecules. The Sr(II) atom is surrounded by six carboxyl-ate O atoms from four separate quinoline-3-carboxyl-ate ligands and two O atoms from two coordinated water mol-ecules. The bri...

correlations between carcinogenicity and several molecular orbital characteristics were found. All correlations between molecular orbital properties and carcinogenicity were modified by one or more of the following structural factors: (a) the absence of a 4-nitro group, (b) the absence of a 1-oxide group, or (c) the presence of bulky substituents in position 2 or 3 of the quinoline ring. Any of...

The asymmetric unit of the title structure, C(28)H(19)NO·0.5C(3)H(6)O, comprises one 2-(anthracen-9-yl)-10-meth-oxy-benzo[h]-quinoline mol-ecule and an acteone mol-ecule with an occupany of 0.5. The solvent mol-ecule is disordered around a centre of symmetry. Its occupancy was determined from NMR data and kept fixed during the refinement. The two conjugated ring systems of the mol-ecule are alm...
