1,2,3-Trifluoro-benzene.

ABSTRACT: In the title compound, C(6)H(3)F(3), weak electrostatic and dispersive forces between C(?+)-F(?-) and H(?+)-C(?-) groups are at the borderline of the hydrogen-bond phenomenon and are poorly directional and further deformed in the presence of ?-? stacking inter-actions. The mol-ecule lies on a twofold rotation axis. In the crystal structure, one-dimensional tapes are formed via two anti-dromic C-H?F hydrogen bonds. These tapes are, in turn, connected into corrugated two-dimensional sheets by bifurcated C-H?F hydrogen bonds. Packing in the third dimension is furnished by ?-? stacking inter-actions with a centroid-centroid distance of 3.6362?(14)?Å.

In the title compound, C(6)H(3)F(3), weak electrostatic and dispersive forces between C(δ+)-F(δ-) and H(δ+)-C(δ-) groups are at the borderline of the hydrogen-bond phenomenon and are poorly directional and further deformed in the presence of π-π stacking inter-actions. The mol-ecule lies on a twofold rotation axis. In the crystal structure, one-dimensional tapes are formed via two anti-dromic C-H⋯F hydrogen bonds. These tapes are, in turn, connected into corrugated two-dimensional sheets by bifu ...[more]

Multi-Armed 1,2,3-Selenadiazole and 1,2,3-Thiadiazole Benzene Derivatives as Novel Glyoxalase-I Inhibitors.

Project description:Glyoxalase-I (Glo-I) enzyme was established to be a valid target for anticancer drug design. It performs the essential detoxification step of harmful byproducts, especially methylglyoxal. A robust computer-aided drug design approach was used to design and validate a series of compounds with selenium or sulfur based heterorings. A series of in-house multi-armed 1,2,3-selenadiazole and 1,2,3-thiadiazole benzene derivatives were tested for their Glo-I inhibitory activity. Results showed that these compounds bind Glo-I active sites competitively with strong potential to inhibit this enzyme with IC50 values in micro-molar concentration. Docking poses revealed that these compounds interact with the zinc atom at the bottom of the active site, which plays an essential role in its viability.

Project description:In the title compound, C(14)H(10)F(3)NO(2), the two benzene rings are oriented at a dihedral angle of 31.94 (14)°. An intra-molecular O-H⋯N hydrogen bond helps to stabilize the mol-ecular structure. In the crystal, inter-molecular O-H⋯O hydrogen bonding links the mol-ecules, forming chains running along the crystallographic a axis. The F atoms of the trifluoro-methyl group are disordered over two positions with refined site occupancies of 0.488 (5) and 0.512 (5).

4-[5-(Furan-2-yl)-3-trifluoro-methyl-1H-pyrazol-1-yl]benzene-sulfonamide.

Project description:In the title compound, C(14)H(10)F(3)N(3)O(3)S, there are significant twists in the mol-ecule, as seen in the values of the dihedral angles between the pyrazole ring and each of the furan [31.1?(2)°] and benzene rings [55.58?(10)°]. The amino N atom occupies a position almost normal to the benzene ring [N-S-C(ar)-C(ar) (ar = aromatic) torsion angle = 83.70?(19)°]. One amino H atom forms a hydrogen bond to the tricoordinate pyrazole N atom and the other inter-acts with a sulfonamide O atom, forming a supra-molecular chain along [010]. The chains are consolidated into a supra-molecular layers via C-H?O inter-actions involving the second sulfonamide O atom; layers stack along [10-1]. The furan ring was found to be disordered over two diagonally opposite orientations of equal occupancy.
