2,3-Dimethyl-6-nitro-2H-indazole.

ABSTRACT: In the mol-ecule of the title compound, C(9)H(9)N(3)O(2), the indazole ring system is almost planar [maximum deviation = 0.019?(3)?Å for the C atom bearing the nitro group]. In the crystal structure, inter-molecular C-H?O inter-actions link the mol-ecules into centrosymmetric dimers, forming R(2) (2)(18) ring motifs. Aromatic ?-? contacts between indazole rings [centroid-centroid distances = 3.632?(1) and 3.705?(1)?Å] may further stabilize the structure.

In the mol-ecule of the title compound, C(9)H(9)N(3)O(2), the indazole ring system is almost planar [maximum deviation = 0.019 (3) Å for the C atom bearing the nitro group]. In the crystal structure, inter-molecular C-H⋯O inter-actions link the mol-ecules into centrosymmetric dimers, forming R(2) (2)(18) ring motifs. Aromatic π-π contacts between indazole rings [centroid-centroid distances = 3.632 (1) and 3.705 (1) Å] may further stabilize the structure. ...[more]

2-Allyl-7-nitro-2H-indazole.

Project description:The asymmetric unit of the title compound, C10H9N3O2, contains two independent mol-ecules linked by a C-H?N hydrogen bond. Each mol-ecule has a similar conformation, being built up from fused five- and six-membered rings, each linked to an ally and nitro group, respectively. The indazole ring system makes dihedral angles of 2.7?(2) and 2.2?(2)°, respectively, with the plane through the nitro group. The allyl group is nearly perpendicular to the indazole system, as indicated by the N-N-C-C torsion angles of -75.3?(2) and -82.2?(2)°, this being the most important difference between the conformations of the two mol-ecules. In the crystal, mol-ecules are linked by C-H?O and ?-? [inter-centroid distance = 3.6225?(8)?Å] inter-actions to form a three-dimensional network.

Project description:In the title compound, C(8)H(7)N(3)O(2), the mol-ecular skeleton is almost planar with a maximum deviation of 0.0484?(9)?Å for the methyl C atom. In the crystal, weak inter-molecular C-H?N and C-H?O hydrogen bonds help to establish the packing.

2,3-Dimethyl-6-nitro-quinoxaline.

Project description:The asymmetric unit of the title quinoxaline compound, C(10)H(9)N(3)O(2), contains two crystallographically independent mol-ecules (A and B). The quinoxaline ring systems are essentially planar, with maximum deviations of 0.006 (1) and 0.017 (1) Å, respectively, for mol-ecules A and B. In mol-ecule A, the dihedral angle formed between the quinoxaline ring system and nitro group is 10.94 (3)° [6.31 (13)° for mol-ecule B]. In the crystal, mol-ecules are linked into chains propagating along [001]: one forms zigzag chains linked by C-H⋯O hydrogen bonds, whilst the other forms ladder-like chains by way of C-H⋯N and C-H⋯O hydrogen bonds. The packing is further consolidated by weak π-π inter-actions [range of centroid-centroid distances = 3.5895 (7)-3.6324 (7) Å].

3,4-Dimethyl-pyrano[2,3-c]pyrazol-6(2H)-one.

Project description:The asymmetric unit of the title compound, C(8)H(8)N(2)O(2), comprises two independent mol-ecules in both of which, all non-H atoms lie in a common plane (r.m.s. deviation = 0.014 and 0.017?Å). In the crystal, N-H?O hydrogen bonds connect the mol-ecules into zigzag chains running along [10-1]. Weak C-H?O inter-actions connect the chains into an infinite network.

Synthesis and Cytotoxic Activity of Combretastatin A-4 and 2,3-Diphenyl-2H-indazole Hybrids.

Project description:Cancer is the second leading cause of death, after cardiovascular diseases. Different strategies have been developed to treat cancer; however, chemotherapy with cytotoxic agents is still the most widely used treatment approach. Nevertheless, drug resistance to available chemotherapeutic agents is still a serious problem, and the development of new active compounds remains a constant need. Taking advantage of the molecular hybridization approach, in the present work we designed, synthesized, and tested the cytotoxic activity of two hybrid compounds and seven derivatives based on the structure of combretastatin A-4 and 2,3-diphenyl-2H-indazole. Practical modifications of reported synthetic protocols for 2-pheny-2H-indazole and 2,3-dipheny-2H-indazole derivatives under microwave irradiation were implemented. The cytotoxicity assays showed that our designed hybrid compounds possess strong activity, especially compound 5, which resulted even better than the reference drug cisplatin against HeLa and SK-LU-1 cells (IC50 of 0.16 and 6.63 µM, respectively), and it had similar potency to the reference drug imatinib against K562 cells. Additionally, in silico and in vitro studies strongly suggest tubulin as the molecular target for hybrid compound 5.

The dihedral angle between the nitro group and its parent benzene ring is 9.22?(16)°.

2-(2,3-Dimethyl-phen-yl)-1H-isoindole-1,3(2H)-dione.

Project description:In the title compound, C(16)H(13)NO(2), the 2,3-dimethyl-phenyl group and the 1H-isoindole-1,3(2H)-dione group are essentially planar, with r.m.s. deviations of 0.006 and 0.013 Å, respectively, and are oriented at an angle of 78.19 (3)° with respect to each other. In the crystal, weak C-H⋯O inter-actions link the mol-ecules, forming a zigzag chain parallel to the b axis. Futhermore, C-H⋯π inter-actions are present between the C-H group of isoindole and the 2,3-dimethyl-phenyl benzene ring. The H atoms of the ortho-methyl group are statistically disordered over two positions. Such disorder might be related to the antagonism between intra-molecular steric repulsions and inter-molecular C-H⋯O inter-actions.
