ABSTRACT. Quorum sensing (QS), used by many pathogenic bacteria to express virulence factors, is seen as a new and effective strategy combat resistant bacteria. In this study, theoretical investigations were made on the structural data of molecules support inhibition effects 2-amino 4-chloro benzoic acid 4-amino 2-chloro molecules. Theoretical calculations performed using density functional the...

In the title compound, the dihedral angles between the 2-amino-5-chloro-pyridyl rings and the pyridine ring are 56.26 (6)° and 78.83 (5)°; the angle between the 2-amino-5-chloro-pyridyl rings is 72.42 (5)°. The solvent water mol-ecules are linked to the organic compound by N-H⋯O, O-H⋯O, N-H⋯N and O-H⋯N hydrogen bonds. π⋯π Stacking inter-actions are also observed between the 2-amino-5-chloro-pyr...

Water-soluble gold(I) complexes [1-mesityl-3-(3-sodiumsulfonatopropyl)imidazol-2-ylidene] gold(I) Chloro (3) and [1,3-bis(2,6-diisopropyl-4-sodiumsulfonatophenyl)imidazol-2-ylidene] gold(I) Chloro (4) were prepared, in high yield, by carbene transmetallation from the appropriate NHC silver complex with chloro tetrahydrothiophene gold ([AuCl(tht)]). The antimicrobial properties of both gold(I) c...

In the title compound, C(17)H(15)ClO(2)S, the O atom and the 4-chloro-phenyl group of the 4-chloro-phenyl-sulfinyl substituent are located on opposite sides of the plane through the benzofuran fragment; the 4-chloro-phenyl ring is approximately perpendicular to this plane [dihedral angle = 87.12 (3)°]. In the crystal structure, mol-ecules are linked through a weak inter-molecular C-H⋯O hydrogen...

In the title hydroxamic acid derivate, C(21)H(14)N(2)O(5)Cl(2), the nitro-substituted benzene ring forms dihedral angles of 66.0 (2) and 59.6 (2)°, with the p-chloro and o-chloro-substituted benzene rings, respectively. The dihedral angle between the two chloro-substituted benzene rings is 64.2 (2) Å. In the crystal, weak C-H⋯O hydrogen bonds link the mol-ecules along [010]. The crystal studied...

The title compound, C(19)H(13)ClO(3)S, was prepared by the oxidation of 3-(4-chloro-phenyl-sulfan-yl)-2-methyl-naphtho[1,2-b]furan with 3-chloro-peroxy-benzoic acid. The 4-chloro-phenyl ring makes a dihedral angle of 68.59 (5)° with the plane of the naphthofuran fragment. The crystal structure is stabilized by π-π inter-actions between the benzene rings of neighbouring mol-ecules [centroid-cent...

The title compound, C(6)H(14)N(2) (2+)·2C(7)H(4)ClO(2) (-), contains trimeric units linked by N-H⋯O hydrogen bonds. The carboxyl-ate groups of the 2-chloro-benzoate anions form dihedral angles of 66.1 (1) and 76.1 (1)° with the respective chloro-benzene rings to which they are bound. The hydrogen-bonded trimers are arranged in layers in the (200) planes and the chloro-benzoate anions form edge-...

Reactions of 2-chloro-4-fluoropyridine (8), 2-chloro-4-nitropyridine (9), and their corresponding N-oxides 7 and 3 with the n-heptanolate anion were investigated in three solvents. The desired 2-chloro-4-heptyloxypyridine-N-oxide (4a) was obtained most efficiently from 3 in DMSO. A reaction of 4a with AcSNa followed by deacetylation with MeONa gave the sodium salt of 4-heptyloxy-1-hydroxypyridi...

The asymmetric unit of the title compound, C(21)H(18)ClN(3)O, contains two crystallographically independent mol-ecules which differ slightly in the orientations of chloro-benz-yloxy units. In one of the mol-ecules, the phenyl and chloro-phenyl rings are oriented at dihedral angles of 38.09 (6) and 42.15 (6)°, respectively, with respect to the benzotriazole ring [43.23 (6) and 29.80 (6)° in the ...

The amide group in the structure of the title compound (N35DCP2CBA), C(13)H(8)Cl(3)NO, is trans-planar, similar to that observed in N-(3-chloro-phen-yl)benzamide, N-(3,5-dichloro-phen-yl)benzamide, 2-chloro-N-phenyl-benzamide and other benzanilides. The C=O bond in N35DCP2CBA is anti to the ortho-chloro substituent in the benzoyl ring. The amide group makes dihedral angles of 63.1 (12) and 31.1...
