In the title compound, C(11)H(12)ClN(5)O, the triazolone and pyrimidine rings are almost coplanar [dihedral angle = 2.98 (14)°]. The total puckering amplitude Q(T) of the seven-membered lactam ring is 0.706 (3) Å.

In the title compound, C(10)H(6)ClF(3)N(4)O(3), the dihedral angle between the benzene ring and the triazolone ring is 59.9 (1)°, while the nitro substituent subtends an angle of 39.5 (1)° to the benzene ring plane. In the crystal, pairs of mol-ecules form inversion dimers via C-H⋯O hydrogen bonds.

In the crystal structure of the title compound, C(10)H(7)ClF(3)N(3)O, pairs of mol-ecules are connected into dimers via pairs of C-H⋯O hydrogen bonds. The dihedral angle between the benzene ring and attached triazolone ring is 53.2 (1)°.

The inhibitory action of some herbicides on photosynthetic electron flow at photosystem II in isolated chloroplasts was investigated. Emphasis in the study is on compounds, whose chemical structure seemed to be in disaccordance with the basic structural element, proposed to be required for a photosystem II inhibitor. The effective inhibition of photosynthetic oxygen evolution by N-alkylated ure...

a series of 3-alkoxy-4-(4-(hexyloxy/heptyloxy) phenyl)-4h-1,2,4-triazole was synthesized. the anticonvulsant effect and neurotoxicity of the compounds were calculated with maximal electroshock (mes) test and rotarod tests with intraperitoneally injected mice. among the synthesized compounds, compound 3-heptyloxy-4-(4-(hexyloxy) phenyl)-4h-1,2,4-triazole (5f) was the most active one and also had...

Sterol 14α-demethylases from Cytochrome P450 family (CYP51s) are essential enzymes in sterol biosynthesis and well-known as the target of antifungal drugs. The 3D structure of CYP51A from Penicillium italicum (PiCYP51A) was constructed through homology modeling based on the crystal structure of human CYP51A (PDB: 3LD6). Molecular dynamics (MD) simulation was operated to relax the initial model ...

The present study aims to develop new energetic composites containing nanostructured nitrocellulose (NNC) or nitrated cellulose (NC), hydrazinium nitro triazolone (HNTO), and MgAl-CuO nanothermite. prepared formulations (NC/HNTO/MgAl-CuO NNC/HNTO/MgAl-CuO) were analyzed using various analytical techniques, such as Fourier-transform infrared (FTIR), scanning electron microscopy (SEM), thermograv...
