Theoretical study of chloride complexes with hybrid macrocycles

Anions show relevant roles in biological routes. The supramolecular chemistry investigates the chemical bonding between two or more molecules and/or ions. Herein, the nature of the bond between chloride anions and macrocycle receptors elaborated from (i) pyridines, (ii) pyrroles, (iii) borazines, (iv) triazines, and (v) 1,2,3-triazole rings are studied. The energy decomposition analysis (EDA) shows that the receptors that predominantly establish non-covalent interactions with the Cl- anions proportionate a preferable bond than the macrocycles that mostly form a covalent interaction with the Cl- anions. The substitution of pyridine by borazine rings in the macrocycles or the protonation of the receptors increases the interaction with the Cl- anions since there is an increase in the number of -BH or -NH groups available to establish hydrogen bonds with the Cl- anions. In addition, the pyridine -> borazine substitution decreases the number of repulsive interactions. The substitution of pyrrole by 1,2,3-triazole rings does not relevantly favor the interaction with the Cl- anions. The substitution of pyridine by the triazine rings or the addition of electron-withdrawing groups (-OH, -F and -NO2) in the receptor structures increases the acidity of the cavity of the macrocycles and, therefore, favors the interaction with the Cl- anions. The addition of electron-donating groups (-NH2) to the receptor structure promotes the opposite effect. Accordingly, the present investigation brings relevant information for the design of new hybrid macrocycles with the potential for anionic recognition.

Convergent synthesis of carbonic anhydrase inhibiting bi-heterocyclic benzamides: Structure-activity relationship and mechanistic explorations through enzyme inhibition, kinetics, and computational studies

By using a convergent methodology, a novel series of N-arylated 4-yl-benzamides containing a bi-heterocyclic thiazole-triazole core was synthesized, and the structures of these hybrid molecules, 9a-k, were corroborated through spectral analyses. The in vitro studies of these multifunctional molecules demonstrated their potent carbonic anhydrase inhibition relative to the standard used. The kinetics mechanism was exposed by Lineweaver-Burk plots, which revealed that 9j inhibited carbonic anhydrase non-competitively by forming an enzyme-inhibitor complex. The inhibition constants K-i calculated from Dixon plots for this compound was 1.2 mu M. The computational study was also persuasive with the experimental results, and these molecules disclosed good results of all scoring functions and interactions, which suggested a good binding to carbonic anhydrase. So, it was predicted from the inferred results that these molecules might be considered as promising medicinal scaffolds for various diseases related to the uncontrolled production of this enzyme.

Intracellular Mutual Promotion of Redox Homeostasis Regulation and Iron Metabolism Disruption for Enduring Chemodynamic Therapy

Intracellular redox homeostasis and the iron metabolism system in tumor cells are closely associated with the limited efficacy of chemodynamic therapy (CDT). Despite extensive attempts, maintaining high levels of intracellular catalysts (free iron) and reactants (H2O2) while decreasing the content of reactive oxygen species (ROS) scavengers (especially glutathione (GSH)) for enduring CDT still remains great challenges. Herein, S-S bond-rich dendritic mesoporous organic silica nanoparticles (DMON) are utilized as GSH-depleting agents. After co-loading Fe-0 and a catalase inhibitor (3-amino-1,2,4-triazole (AT)), a novel biodegradable nanocarrier is constructed as DMON@Fe-0/AT. In the mildly acidic tumor microenvironment, on-demand ferrous ions and AT are intelligently released. AT suppresses the activity of catalase for H2O2 hoarding, and the exposed DMON weakens ROS scavenging systems by persistently depleting intracellular GSH. The highly efficient center dot OH production by DMON@Fe-0/AT can effectively attack mitochondria and downregulate the expression of ferroportin 1, which can disrupt the cellular iron metabolism system, leading to the desired retention of iron in the cytoplasm. More importantly, DMON@Fe-0/AT exhibits a much more efficient CDT killing effect on 4T1 tumor cells than plain Fe-0 nanoparticles, benefiting from their synergistic redox regulation and iron metabolism disruption. Overall, the as-prepared intelligent, degradable DMON@Fe-0/AT provides an innovative strategy for enduring CDT.

Immobilized galactose oxidase in alginate gel (GO-Bead): a versatile and efficient biocatalyst for the regioselective synthesis of 1,4-disubstitued-1,2,3-triazoles: click reaction

Galactose oxidase (E.C. 1.1.3.9) is an extracellular oxidoreductase enzyme containing Cu(I) which is produced by some fungi like Fusarium species. The enzyme catalyzes the selective oxidation of primary alcohols like galactose. In this study, a heterogeneous enzymatic system for click reaction was prepared. The most important advantage of the heterogeneous catalyst is the ease of separation and their possible reusability. Therefore, galactose oxidase was immobilized by entrapment; for this purpose, alginate polysaccharide beads with different diameters were synthesized and galactose oxidase was immobilized into them to obtain galactose oxidase-bead (GO-Bead). Next, the catalytic activity of galactose oxidase-beads was examined in the one-pot synthesis of 1,4-disubstituted 1,2,3-triazoles via click reaction comprising diversely benzyl halides, sodium azide and different alkynes in aqueous medium which need Cu(I) for their performance. The catalyst was conventionally recovered and effectively reused in several runs with no appreciable decrease in its catalytic activity.

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.

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.

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).

Separation of chalcopyrite from galena with 3-amyl-4-amino-1, 2, 4-triazole-5-thione collector: Flotation behavior and mechanism

3-Amyl-4-amino-1,2,4-triazole-5-thione (AATT) reacted with Cu2+ or Pb2+ ions in aqueous solutions to form CuAATT and Pb(AATT)(2) complexes and their solubility product constants were measured as 10(-16.17) and 10(-20.60), respectively. In the moderately-alkaline media, both chalcopyrite and galena chemisorbed AATT on to their surfaces, and the adsorption amount of AATT on chalcopyrite was bigger than that on galena, which rendered a stronger hydrophobization toward chalcopyrite. While under the high-alkaline pulp, AATT only chemisorbed on chalcopyrite, not on galena. The micro-flotation findings indicated that AATT was a favorable collector for flotation enrichment of chalcopyrite and galena at pH <11.0, and realized an efficient flotation separation of chalcopyrite from galena under pH>11.5. The CuAATTcomplex was more insoluble than Pb(AATT)2, which implied a stronger affinity of AATT toward chalcopyrite than galena and returned their selective flotation separation at the high-alkaline condition.
