In the title compound, C(11)H(9)FN(2)O(3), the benzene ring is almost coplanar with the heterocyclic ring, making a dihedral angle of 14.0 (1)°. The plane of the carboxyl group is rotated by 14.7 (3)° with respect to the 1,2,4-oxadiazole ring plane. The aliphatic chain exhibits a standard zigzag arrangement. Two inter-molecular O-H⋯O hydrogen bonds between the carboxyl groups related by an inve...

Molecules of the title compound, C(9)H(8)N(2)O(2), are linked into complex sheets by a combination of N-H...O, C-H...N and C-H...O hydrogen bonds.

Herein we report the synthesis and evaluation of a series of new pramipexole derivatives as highly potent and selective agonists of the dopamine-3 (D3 ) receptor. A number of these new compounds bind to the D3 receptor with sub-nanomolar affinity and show excellent selectivity (>10,000) for the D3 receptor over the D1 and D2 receptors. For example, compound 23 (N-(cis-3-(2-(((S)-2-amino-4,5,6,7...

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 ...

IN THE TITLE SYDNONE COMPOUND [SYSTEMATIC NAME: 3-(2,3-dimethyl-5-oxo-1-phenyl-2,5-dihydro-1H-pyrazol-4-yl)-1,2,3-oxadiazol-3-ium-5-olate], C(13)H(12)N(4)O(3), the oxadiazole and pyrazole rings are essentially planar [maximum deviations = 0.006 (1) and 0.019 (1) Å, respectively] and are inclined at inter-planar angles of 37.84 (4) and 46.60 (4)°, respectively, with respect to the benzene ring. ...

The title compound, C(15)H(16)N(6)O(2)S, exists in a trans configuration with respect to the acyclic N=C bond. The 1,2,3-oxadiazol-3-ium ring makes dihedral angles of 10.59 (8) and 73.94 (8)°, respectively, with the 1,2,4-triazole and benzene rings. The mol-ecular structure is stabilized by an intra-molecular C-H⋯S hydrogen bond, which generates an S(6) ring motif. In the crystal, mol-ecules ar...

New pyrazoline derivatives were synthesized and evaluated for their cytotoxic effects on AsPC-1 human pancreatic adenocarcinoma, U87 and U251 human glioblastoma cell lines. 1-[((5-(4-Methylphenyl)-1,3,4-oxadiazol-2-yl)thio)acetyl]-3-(2-thienyl)-5-(4-chlorophenyl)-2-pyrazoline (11) was found to be the most effective anticancer agent against AsPC-1 and U251 cell lines, with IC50 values of 16.8 µM...

Background: New amino derivatives of NBD type are high interest due to their strong fluorescence, while compounds containing a disulphide moiety in nano-chemistry easiness attaching noble nanoparticles. Therefore, this work new fluorescent derivative and cystamine was obtained. Methods: The reaction between NBD-chloride occurs straightforwardly, the isolated compound characterized by IR, UV-Vis...
