Regioselective 1,3-Dipolar Cycloaddition of Nitriles with Nitrile Imines Generated from Tetrazoles

A synthesis of 3,5-disubstituted-1,2,4-triazoles from nitriles and 5-aryltetrazoles is reported. When 5-aryltetrazoles are triflylated in the presence of nitriles, the resulting 5-aryl-2-triflyltetrazoles thermally generate N-triflyl-nitrile imines through a sequence of ring-chain tautomerization and denitrogenation. The N-triflyl-nitrile imines immediately undergo 1,3dipolar cycloaddition with nitriles in a regioselective manner, forming the corresponding 1,2,4-triazoles.

A family of 2p-3d complexes based on 4,5-dimethyltriazole nitronyl nitroxide radical: synthesis, structure, and magnetic properties

Three 2p-3d complexes were successfully synthesized by using 4,5-dimethyltriazole nitronyl nitroxide radical. All of the complexes with the same formula of [M(hfac)(2)(4,5-di-Me-3-NIT-trz)(2)] [M = Co(II) 1, Ni(II) 2, Cu(II) 3; 4,5-di-Me-3-NIT-trz = 2-[3-(4,5-dimethyl-T2,4-triazolyel-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide; hfac = hexafluomacetylacetone] are characterized by X-ray analysis, and their magnetic properties were studied in detail. The metal ions in 1-3 are all in distorted octahedral configuration with four oxygen atoms from two bidentate hfac ligands, and two triazole N atoms from two different 4,5-di-Me-3-NIT-trz ligands. The magnetic behaviors for 1-3 indicate that the metal ions and the radicals are antiferromagnetically coupled (J(Co-rad) = -7.11 cm(-1), for 1; J(Ni-rad) = -1.63 cm(-1), for 2; J(Cu-rad) = -8.71 cm(-1), for 3). In addition, ferromagnetic coupling exists between the uncoordinated NO radicals in complex 1, while the magnetic reactions J(rad-rad) are antiferromagnetic in complexes 2-3.

Flame-retardant, phosphorous-based polyurethane triazoles via solvent-free and catalyst-free azide-alkyne cycloaddition and their cure kinetics

A novel class of phosphorous-containing polyurethane triazoles (PUTs) with self-extinguishing property is reported. Initially, a set of new urethane diazide monomers were synthesized by reacting diisocyanates (DI) (isophorone (IPDI), hexamethylene (HDI), and toluene (TDI)) with 2-azidoethanol and characterized by FTIR, H-1 NMR, C-13 NMR, and ESI-MS analysis. Later, the corresponding PUTs were synthesized via azide-alkyne cycloaddition of urethane diazides with triprop-2-ynyl phosphate under solvent-free and catalyst-free conditions at 80 degrees C via thermal polymerization. Cure kinetic study of the thermally induced polymerization of PUTs was performed to correlate with isocyanate functionality. The activation energies (Ea) of the PUTs derived from nonisothermal multiheating rate DSC tests were fitted to Borchardt-Daniels model. The Ea’s were found to be proportional to heating rates for all PUTs and confirmed optimum percentage conversion at lower heating rates. The experimental findings were found to corroborate well with Borchardt-Daniels model. The PUTs were characterized by FTIR, TGA, DSC, MCC, LOI, lab-scale flame tests, and EDX analysis. All PUTs were self-extinguishable, but TD-PUT with aromatic functionality (TDI-based) demonstrated superior extinguishing performance with lowest total heat release (6.11 kJ/g), peak heat release rate (42.04 W/g), heat release capacity (85.59 J/g K), and 31% LOI comparatively. Lab-scale flame tests on PUTs confirmed their self-extinguishing property with little or no smoke evolution. Such PUT resins can be blended with conventional polyurethane coatings for fire-retardant applications.

Ecological consequences of space rocket accidents in Kazakhstan between 1999 and 2018

In this paper, we briefly described the ecological consequences of six space rocket accidents launched from the Baikonur Cosmodrome between 1999 and 2018 and focused on an assessment of efficiency of soil remediation following the accidental crash of launch vehicle Proton-M on July 2, 2013, which resulted in the severest environmental impact in the modern Russian space industry. On the day after the accident, the content of carcinogenic unsymmetrical dimethylhydrazine and nitrosodimethylamine, as well as nitrate in soils of the crash site exceeded their maximal permissible concentrations by 8900, 6100 and 85 times, respectively. Mitigation measures included soil detoxication by a solution of 10% H2O2 and 1% iron complexonate, soil excavation and ploughing. Two years later (in April 2015), both unsymmetrical dimethylhydrazine and nitrosodimethylamine concentrations were below 0.05 mg/kg and nitrate concentration did not exceed 3.9 g/kg. As compared to background sites, soils of the crash site had significantly (P-value<0.05) lower values of pH and the content of total organic carbon, basicity from soda and carbonates and higher total nitrogen and soluble salt contents. Soil microbial communities were the most vulnerable component of the disturbed arid ecosystems, as their suppressed condition was indicated by a low biochemical oxygen demand and a very low cellulase activity.

Synthesis, Characterization and In Vitro Evaluation of Novel 5-Ene-thiazolo[3,2-b][1,2,4]triazole-6(5H)-ones as Possible Anticancer Agents

The present paper is devoted to the search for drug-like molecules with anticancer properties using the thiazolo[3,2-b][1,2,4]triazole-6-one scaffold. A series of 24 novel thiazolo-[3,2-b][1,2,4]triazole-6-ones with 5-aryl(heteryl)idene- and 5-aminomethylidene-moieties has been synthesized employing three-component and three-stage synthetic protocols. A mixture of Z/E-isomers was obtained in solution for the synthesized 5-aminomethylidene-thiazolo[3,2-b]-[1,2,4]triazole-6-ones. The compounds have been studied for their antitumor activity in the NCI 60 lines screen. Some compounds present excellent anticancer properties at 10 mu M. Derivatives 2h and 2i were the most active against cancer cell lines without causing toxicity to normal somatic (HEK293) cells. A preliminary SAR study had been performed for the synthesized compounds.

Copper(II) and Zinc(II) Complexes with the Clinically Used Fluconazole: Comparison of Antifungal Activity and Therapeutic Potential

Copper(II) and zinc(II) complexes with clinically used antifungal drug fluconazole (fcz), {[CuCl2(fcz)(2)](.)5H(2)O}(n), 1, and {[ZnCl2(fcz)(2)]Greek ano teleia2C(2)H(5)OH}(n), 2, were prepared and characterized by spectroscopic and crystallographic methods. The polymeric structure of the complexes comprises four fluconazole molecules monodentately coordinated via the triazole nitrogen and two chlorido ligands. With respect to fluconazole, complex 2 showed significantly higher antifungal activity against Candida krusei and Candida parapsilosis. All tested compounds reduced the total amount of ergosterol at subinhibitory concentrations, indicating that the mode of activity of fluconazole was retained within the complexes, which was corroborated via molecular docking with cytochrome P450 sterol 14 alpha-demethylase (CYP51) as a target. Electrostatic, steric and internal energy interactions between the complexes and enzyme showed that 2 has higher binding potency to this target. Both complexes showed strong inhibition of C. albicans filamentation and biofilm formation at subinhibitory concentrations, with 2 being able to reduce the adherence of C. albicans to A549 cells in vitro. Complex 2 was able to reduce pyocyanin production in Pseudomonas aeruginosa between 10% and 25% and to inhibit its biofilm formation by 20% in comparison to the untreated control. These results suggest that complex 2 may be further examined in the mixed Candida-P. aeruginosa infections.
