The present studies were designed to synthesize the three disulfide derivatives bearing S-S bond formation, their characterization and explore antibacterial activity using in silico analysis. They synthesized by condensation reaction of 2-(2-(2-aminophenyl) disulfanyl) benzeneamine with 3-bromo-2-hydroxy-5-nitrobenzaldehyde; 5-bromo-2-hydroxybenzaldehyde 3, 5-dichloro-2-hydroxy-benzaldehyde, re...
The reaction of 3,3-dichloro-2,2,4,4-tetramethylcyclobutanethione (1) with diazo compounds yielded spirocyclic 2,5-dihydro-1,3,4-thiadiazoles 3, which decomposed at ca. 45°C to give the corresponding thiocarbonyl ylide of type 4. In the absence of trapping agents, these thiocarbonyl ylides underwent a 1,3-dipolar electrocyclization to yield spirocyclic thiiranes 5. On the other hand, the thioca...
In the mol-ecule of the title compound, C(22)H(18)Cl(2)N(2)O, the planar benzimidazole ring system is oriented with respect to the phenyl and dichloro-benzene rings at dihedral angles of 12.73 (3) and 36.57 (4)°, respectively. The dihedral angle between the dichloro-benzene and phenyl rings is 29.95 (6)°. There are C-H⋯π contacts between the benzimidazole and dichloro-benzene rings, between the...
The asymmetric unit of the title compound, C(17)H(11)Cl(3)N(2)O(2), contains two independent mol-ecules; the pyrazole rings are oriented with respect to the chloro-phenyl and dichloro-phenyl rings at dihedral angles of 43.00 (3) and 65.06 (4)°, respectively, in one mol-ecule, and 51.17 (3) and 69.99 (3)°, respectively, in the other. Pairs of inter-molecular O-H⋯O hydrogen bonds link the mol-ecu...
In the title compound, C(19)H(18)Cl(4)N(2)O(2), a potential tetra-dentate Schiff base ligand, the dihedral angle between the two benzene rings is 48.01 (10)°. The configuration about the two C=N bonds is E and two intra-molecular O-H⋯N hydrogen bonds make S(6) ring motifs. In the crystal, mol-ecules are linked along the b axis via inter-molecular C-H⋯Cl inter-actions. The crystal structure is f...
Opioid receptors are synthesized in dorsal root ganglia and transported into peripheral terminals of primary afferent neurons. Activation of such receptors results in antinociceptive effects that are most prominent in inflammation. In addition, opioid receptors located on sympathetic postganglionic neuron terminals may be involved in these effects. This study investigates the peripheral analges...
In the title chalcone derivative, C(15)H(9)Cl(3)O, the dihedral angle between the 2-chloro-phenyl and 2,4-dichloro-phenyl rings is 41.79 (14)°. Weak C-H⋯O and C-H⋯Cl intra-molecular inter-actions involving the enone unit generate S(5) ring motifs. In the crystal structure, the mol-ecules are arranged in a head-to-tail manner along the a axis. These chains are stacked along the b axis.
The synthetic procedures to obtain indole derivatives with different acidic functions at position 2 of the indole are reported. The synthesised and tested derivatives comprise 5-tetrazolyl, 1,3,4-oxadiazol-5-yl-2-one, and indole-2-carboxylic acid amides with 5-aminotetrazole, methanesulphonamide and trifluoromethanesulphonamide moieties. The binding affinity was evaluated using [3H]MDL 105,519 ...
