1,3-Dimethyl-5-methyl-sulfonyl-1H-pyrazolo-[4,3-e][1,2,4]triazine.

ABSTRACT: In the title compound, C(7)H(9)N(5)O(2)S, the pyrazolo-[4,3-e][1,2,4]triazine fused-ring system is essentially planar [maximum deviation = 0.0420?(3)?Å]. In the crystal, mol-ecules related by twofold axes are linked into a mol-ecular net via inter-molecular C-H?O and C-H?N hydrogen bonds. ?-? inter-actions are observed between the triazine and pyrazole rings of mol-ecules related by the the twofold axis and inversion symmetry with centroid-centroid distances of 3.778?(3) and 3.416?(3)?Å, respectively.

In the title compound, C(7)H(9)N(5)O(2)S, the pyrazolo-[4,3-e][1,2,4]triazine fused-ring system is essentially planar [maximum deviation = 0.0420 (3) Å]. In the crystal, mol-ecules related by twofold axes are linked into a mol-ecular net via inter-molecular C-H⋯O and C-H⋯N hydrogen bonds. π-π inter-actions are observed between the triazine and pyrazole rings of mol-ecules related by the the twofold axis and inversion symmetry with centroid-centroid distances of 3.778 (3) and 3.416 (3) Å, respect ...[more]

Synthesis, Structural Characterization, and Biological Activity of New Pyrazolo[4,3-e][1,2,4]triazine Acyclonucleosides.

Project description:A series of new pyrazolo[4,3-e][1,2,4]triazine acyclonucleosides 2-5 and 8 were prepared and evaluated for their anticancer activity against human cancer cell lines (MCF-7, K-562) and CDK2/E, as well as Abl protein kinases inhibitors. Lipophilicity of the compounds was determined using C-18 and immobilized artificial membrane (IAM) chromatography. In order to confirm the molecular structures and synthesis pathway of new acyclonucleosides, X-ray analysis was performed for model compound 3. Theoretical calculations at the DFT/B3LYP/6-311++G(d,p) level were used for the characterization of electronic structures of 1-8. The potential antiviral activity of acyclonucleosides 2-8 was tested in silico using molecular docking method.

1,3-Diphenyl-8-trifluoro-methyl-1H-pyrazolo-[3,4-b]quinoline.

Project description:The 1H-pyrazolo-[3,4-b]quinoline (PQ) core of the title mol-ecule, C(23)H(14)F(3)N(3), is aromatic and essentially planar (r.m.s. deviation = 0.015 Å) and the two phenyl substituents at positions 1 and 3 are twisted relative to this fragment by 29.74 (7) and 25.63 (7)°, respectively. In the crystal, mol-ecules are arranged along the b axis into stacks via π-π inter-actions, with an inter-planar distance of the PQ core of 3.489 (4) Å.

1H-Pyrazolo[4,3-g]benzothia-zol-7-amine.

Project description:The mol-ecule of the title compound, C(8)H(6)N(4)S, is almost planar [maximum deviation from the mean plane = 0.020 (1) Å for the S atom]. In the crystal, a supra-molecular three-dimensional arrangement arises from N-H⋯N hydrogen bonds and weak aromatic stacking interactions along the a axis [centroid-centroid separation = 3.582 (2) Å].

Tris(3-amino-5,6-dimethyl-1,2,4-triazine-κN)silver(I) trifluromethane-sulfonate-3-amino-5,6-dimethyl-1,2,4-triazine (1/1).

Project description:The asymmetric unit of the title compound, [Ag(C(5)H(8)N(4))(3)](CF(3)O(3)S)·C(5)H(8)N(4), contains two cations, two anions and two uncoordinated 3-amino-5,6-dimethyl-1,2,4-triazine (admt) ligands. It was prepared from the reaction of silver trifluoro-methane-sulfonate and admt in a 2:3 molar ratio. Both silver(I) ions are bonded to three admt mol-ecules via their 2-position triazine N atoms in almost regular trigonal-planar geometries. Three intra-molecular N-H⋯N hydrogen bonds between adjacent admt mol-ecules in each cation help to maintain their overall near planarities (r.m.s. deviations for the 28 non-H atoms = 0.139 and 0.153 Å). In the crystal, numerous N-H⋯N, N-H⋯O, C-H⋯O, C-H⋯N and C-H⋯F hydrogen-bonding interactions link the components into a three-dimensional network.

Preparation of Novel Pyrazolo[4,3-<i>e</i>]tetrazolo[1,5-<i>b</i>][1,2,4]triazine Sulfonamides and Their Experimental and Computational Biological Studies.

Project description:Pyrazolo[4,3-e]tetrazolo[1,5-b][1,2,4]triazine sulfonamides constitute a novel class of heterocyclic compounds with broad biological activity, including anticancer properties. Investigated in this study, MM-compounds (MM134, MM136, MM137, and MM139) exhibited cytotoxic and proapoptotic activity against cancer cell lines (BxPC-3, PC-3, and HCT-116) in nanomolar concentrations without causing cytotoxicity in normal cells (L929 and WI38). In silico predictions indicate that tested compounds exhibit favorable pharmacokinetic profiles and may exert anticancer activity through the inhibition of BTK kinase, the AKT-mTOR pathway and PD1-PD-L1 interaction. Our findings point out that these sulfonamide derivatives may constitute a source of new anticancer drugs after optimization.

Ethyl 2-(3,4-dimethyl-5,5-dioxo-1H,4H-benzo[e]pyrazolo-[4,3-c][1,2]thia-zin-1-yl)acetate.

Project description:In the title mol-ecule, C(15)H(17)N(3)O(4)S, the heterocyclic thia-zine ring adopts a twist-boat conformation, which differs from that in related compounds, with adjacent S and C atoms displaced by 0.981?(4) and 0.413?(5)?Å, respectively, on the same side of the mean plane formed by the remaining ring atoms. The mean plane of the benzene ring makes a dihedral angle of 23.43?(14)° with the mean plane of the pyrazole ring. In the crystal, mol-ecules are connected by weak C-H?O hydrogen bonds to form a three-dimensional network. The H atoms of the methyl group attached to the pyrazole ring were refined over six sites with equal occupancies.

6-[(Dimethyl-amino)methyl-ene-amino]-1,3-dimethyl-pyrimidine-2,4(1H,3H)-dione dihydrate.

Project description:Uracil, the pyrimidine nucleobase, which combined with adenine forms one of the major motifs present in the biopolymer RNA, is also involved in the self-assembly of RNA. In the title compound, C(9)H(14)N(4)O(2)·2H(2)O, the asymmetric unit contains one dimethyl-amino-uracil group and two water mol-ecules. The plane of the N=C-NMe(2) side chain is inclined at 27.6?(5)° to the plane of the uracil ring. Both water mol-ecules form O-H?O hydrogen bonds with the carbonyl O atoms of the uracil group. Additional water-water hydrogen-bond inter-actions are also observed in the crystal structure. The O-H?O hydrogen bonds lead to the formation of a two-dimensional hydrogen-bonded network cage consisting of two dimethyl-amino-uracil groups and six water mol-ecules.

Project description:In the cation of the title compound, C10H13N2O(+)·I(-), all non-H atoms, with the exception of the O atom, are essentially coplanar, with a maximum deviation of 0.04?(1)?Å. In the crystal, the cations and anions are arranged in layers parallel to (100). The cations are connected to the anions via an O-H?I hydrogen bond and there are significant ?-? stacking inter-actions between cation layers, with centroid-centroid distances in the range 3.606?(5)-3.630?(5)?Å. A weak intra-molecular C-H?O hydrogen bond is also observed. The crystal studied was an inversion twin with refined components of 0.52?(5) and 0.48?(5).
