Synthesis and biological evaluation of heterocyclic 1,2,4-triazole scaffolds as promising pharmacological agents

Background Triazole is an important heterocyclic moiety that occupies a unique position in heterocyclic chemistry, due to its large number of biological activities. It exists in two isomeric forms i.e. 1,2,4-triazole and 1,2,3-triazole and is used as core molecule for the design and synthesis of many medicinal compounds. 1,2,4-Triazole possess broad spectrum of therapeutically interesting drug candidates such as analgesic, antiseptic, antimicrobial, antioxidant, anti-urease, anti-inflammatory, diuretics, anticancer, anticonvulsant, antidiabetic and antimigraine agents. Methods The structures of all synthesized compounds were characterized by physicochemical properties and spectral means (IR and NMR). The synthesized compounds were evaluated for their in vitro antimicrobial activity against Gram-positive (B. subtilis), Gram-negative (P. aeruginosa and E. coli) bacterial and fungal (C. albicans and A. niger) strains by tube dilution method using ciprofloxacin, amoxicillin and fluconazole as standards. In-vitro antioxidant and anti-urease screening was done by DPPH assay and indophenol method, respectively. The in-vitro anticancer evaluation was carried out against MCF-7 and HCT116 cancer cell lines using 5-FU as standards. Results, discussion and conclusion The biological screening results reveal that the compounds T-5 (MICBS, EC = 24.7 mu M, MICPA, (CA) = 12.3 mu M) and T-17 (MICAN = 27.1 mu M) exhibited potent antimicrobial activity as comparable to standards ciprofloxacin, amoxicillin (MICCipro = 18.1 mu M, MICAmo = 17.1 mu M) and fluconazole (MICFlu = 20.4 mu M), respectively. The antioxidant evaluation showed that compounds T-2 (IC50 = 34.83 mu g/ml) and T-3 (IC50 = 34.38 mu g/ml) showed significant antioxidant activity and comparable to ascorbic acid (IC50 = 35.44 mu g/ml). Compounds T-3 (IC50 = 54.01 mu g/ml) was the most potent urease inhibitor amongst the synthesized compounds and compared to standard thiourea (IC50 = 54.25 mu g/ml). The most potent anticancer activity was shown by compounds T-2 (IC50 = 3.84 mu M) and T-7 (IC50 = 3.25 mu M) against HCT116 cell lines as compared to standard 5-FU (IC50 = 25.36 mu M).

Pesticides and their degradates in groundwater reflect past use and current management strategies, Long Island, New York, USA

Long Island, New York, has a mix of urban/suburban to agricultural/horticultural land use and nearly 3 million residents that rely on a sole-source aquifer for drinking water. The analysis of shallow groundwater (<40 m below land surface) collected from 54 monitoring wells across Long Island detected 53 pesticides or pesticide degradates. Maximum concentrations for individual pesticides or pesticide degradates ranged from 3 to 368,000 ng/L. The highest concentrations andmost frequent pesticide detections occurred in samples collected from the pesticide management (PM) network, set in an agricultural/horticultural area in eastern Long Island with coordinated pesticide management by state and local agencies. The other two networks (Suffolk and Nassau/Queens) were set in suburban and urban areas, respectively, and had less frequent detections and lower pesticide concentrations than the PMnetwork. Pesticide detections and concentration patterns (herbicide, insecticide, or fungicide) differed among the three networks revealing broad differences in land use. The predominance of fungicides metalaxyl, 1H-1,2,4-triazole (propiconazole/myclobutanil degradate), and 4-hydroxychlorothalonil (HCTL, chlorothalonil degradate) in samples from the PM network reflects their intensive use in agricultural settings. Total fungicide concentrations in the PM network ranged from <10 to >300,000 ng/L. Thewidespread detection of imidacloprid and triazine herbicides, simazine and atrazine, reveal a mixture of current and past use pesticides across the Long Island region. Low concentrations (<200 ng/L) of the triazines in the Suffolk and Nassau/Queens networks may reflect a change in land use and application. Acetanilide herbicides and aldicarb have been discontinued for 20 and 40 years, respectively, yet the concentrations of their degradates were among the highest observed in this study. Acetanilide (total concentrations up to 10,000 ng/L) and aldicarb degradates (up to 270 ng/L) are present in the PM network at much lower concentrations than previous Long Island studies and reflect changes in agricultural practices and pesticide management.

Corrosion Inhibition Effect of Ethyl 1-(4-chlorophenyl)-5-methyl-1H-1,2,3-triazole-4-carboxylate on Aluminium Alloy in Hydrochloric Acid

The inhibition efficiency of Ethyl 1-(4-chlorophenyl)-5-methyl-1H-1,2,3-triazole-4-carboxylate (ETC) on AA6061 Aluminium (Al) alloy in 0.1M HCl solution was tested through weight loss, potentiodynamic polarisation and electrochemical impedance spectroscopy methods. The experimental results show that the inhibition efficiency of ETC increased with an increase in inhibitors concentration and temperature. Potentiodynamic polarisation indicated that the inhibitor is mixed type. From Langmuir isotherm, it was hypothesized the adsorption of inhibitors on AA6061 alloy surface might occur by physical and chemical interaction; however, the activation energy raised suggests a chemisorption process for the interaction of the inhibitor on AA6061 alloy surface. Scanning electron microscopy was used to characterise the surface morphology of the alloy in presence and in the absence of the inhibitor.

One-pot two-step synthesis of fused thiazinofuranone linked geminal bis 1,2,3-triazole hybrids and their in vitro cytotoxic screening

In this study, a series of novel geminal bis 1,2,3-triazoles linked to 2H-furo[2,3-d][1,3]thiazine-2,4,5(1H,6H)-trione (3a-3m) were prepared in one pot starting from 1,3-thiazine-2,6-dione (1) to 6,6-diazido-2H-furo[2,3-d][1,3]thiazine-2,4,5(1H,6H)-trione (2) followed by Cu(I)-catalyzed azide-alkyne cycloaddition. The synthesized compounds were further explored for in vitro cytotoxic activity against PC3, A549, MCF-7, and HeLa cell lines and results revealed that the five compounds 3c, 3d, 3g, 3l, and 3m have displayed comparable in vitro cytotoxic activity with the standard drug Etoposide.

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.

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.

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.
