Abstract
The first examples of [2]catenanes capable of selective anion transport across a lipid bilayer are reported. The neutral halogen bonding (XB) [2]catenanes were prepared via a chloride template-directed strategy in an unprecedented demonstration of using XB⋅⋅⋅anion interactions to direct catenane assembly from all-neutral components. Anion binding experiments in aqueous-organic solvent media revealed strong halide over oxoanion selectivity, and a marked enhancement in the chloride and bromide affinities of the catenanes relative to their constituent macrocycles. The catenanes additionally displayed an anti-Hofmeister binding preference for bromide over the larger iodide anion, illustrating the efficacy of employing sigma-hole interactions in conjunction with the mechanical bond effect to tune receptor selectivity. Transmembrane anion transport studies conducted in POPC LUVs revealed that the catenanes were more effective anion transporters than the constituent macrocycles, with high chloride over hydroxide selectivity, which is critical to potential therapeutic applications of anionophores. Remarkably these outperform existing acyclic halogen bonding anionophores with regards to this selectivity. Record chloride over nitrate anion transport selectivity was also observed. This represents a rare example of the direct translation of intrinsic anion binding affinities to anion transport behaviour, and demonstrates the key role of the catenane mechanical bond effect for enhanced anion transport selectivity.

Abstract
The first examples of halogen bonding (XB) heteroditopic homo[2]catenanes were prepared by discrete Na+ template-directed assembly of oligo(ethylene glycol) units derived from XB donor-containing macrocycles and acyclic bis-azide precursors, followed by a CuI -mediated azide-alkyne cycloaddition macrocyclisation reaction. Extensive 1 H NMR spectroscopic studies show the [2]catenane hosts exhibit positive cooperative ion-pair recognition behaviour, wherein XB-mediated halide recognition is enhanced by alkali metal cation pre-complexation. Notably, subtle changes in the catenanes' oligo(ethylene glycol) chain length dramatically alters their ion-binding affinity, stoichiometry, complexation mode, and conformational dynamics. Solution-phase and single-crystal X-ray diffraction studies provide evidence for competing host-separated and direct-contact ion-pair binding modes. We further demonstrate the [2]catenanes are capable of extracting solid alkali-metal halide salts into organic media.

Abstract
A chemical sensor that can induce near-infrared red-shifted response represents a promising strategy for the design and development of anion probes. In this work, novel CH-controlled colorimetric probe 3 based on anthracene carboximide was developed for near-infrared detection of cyanide. Probe 3 consisted of CHCN binding site to anthracene carboximide fluorophore, and showed a significant visual change from yellow-green (535 nm) to deep violet (825 nm) with a larger redshift (≈ 290 nm) and fluorescence quenching at 480 nm and 520 nm upon interacting with cyanide. Job curves determined 1:1 binding stoichiometry of probe 3 with cyanide. Additonally, probe 3 detected cyanide ion conveniently in aqueous solution and could be reused after trifluoroacetic acid treatment. Colorimetric test paper was used to detect cyanide in aqueous solutions. The C-H deprotonation sensing mechanism was confirmed by 1H NMR titration. The near-infrared detection of cyanide by CH-controlled probes was founded for the first time.

Abstract
H-bond donor catalysts able to modulate the reactivity of ionic substrates for asymmetric reactions have gained great attention in the past years, leading to the development of cooperative multidentate H-bonding supramolecular structures. However, there is still a lack of understanding of the forces driving the ion recognition and catalytic performance of these systems. Herein, insight into the cooperativity nature, anion binding strength, and folding mechanism of a model chiral triazole catalyst is presented. Our combined experimental and computational study revealed that multi-interaction catalysts exhibiting weak binding energies (≈3-4 kcal mol-1 ) can effectively recognize ionic substrates and induce chirality, while strong dependencies on the temperature and solvent were quantified. These results are key for the future design of catalysts with optimal anion binding strength and catalytic activity in target reactions.

[PMID: 30360747 DOI: 10.2174/1573406414666181024111522] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2018] [Revised: 07/23/2018] [Accepted: 10/10/2018] [Indexed: 11/22/2022]
Abstract
BACKGROUND The trypanosomatids, such as the protozoan Leishmania spp., have a demand by ergosterol, which is not present in the membrane from mammal cells. The suppression of the synthesis of ergosterol would be a new target of compounds with leishmanicidal activity, and bistriazole has shown trypanocidal activity by this mechanism. The incidence of fungal infections has increased at an alarming rate over the last decades. This is related both to the growing population of immune-compromised individuals and to the emergence of strains that are resistant to available antifungals. Therefore, there is a challenge for the search of potential new antifungal agents. OBJECTIVE The study aimed to synthesize 1,4-disubstituted-1,2,3-bistriazoles by optimized copper( I)-catalyzed alkyne-azide cycloaddition (CuAAC) and evaluate their antifungal and antitrypanosomastid activities. METHOD The synthesis of symmetrical bistriazoles with diazides as spacers was planned to be performed following the CuAAC reaction strategy. For evaluation of best conditions for the synthesis of symmetrical bistriazoles hex-1-yne 2 was chosen as leading compound, and a variety of catalysts were employed, choosing (3:1) alkyne:diazide stoichiometric relationship employing CuSO4.5H2O as the best condition. For the preparation of diversity in the synthesis of symmetrical bistriazoles, a 1,3-diazide-propan-2-ol 1a and 1,3-diazidepropane 1b were reacted with seven different alkynes, furnishing eleven symmetrical bistriazoles 9-13a,b and 14a. All compounds were essayed to cultures of promastigotes of L. amazonensis (1 x 106 cells mL-1) in the range of 0.10 - 40.00 µg mL-1 and incubated at 25ºC. After 72 h of incubation, the surviving parasites were counted. For antifungal assay, the minimum inhibitory concentrations (MIC) for yeasts and filamentous fungi were determined. Each compound was tested in 10 serial final concentrations (64 to 0.125 µg mL-1). RESULTS Eleven 1,4-disubstituted-1,2,3-bistriazoles were synthesized and their structures were confirmed by IR, 1H and 13C-NMR and Mass spectral analysis. The antifungal and antitrypanosomastid activities were evaluated. The best result to antifungal activity was reached by bistriazole 11a that showed the same MIC of fluconazole (32 µg mL-1) against Candida krusei ATCC 6258, an emerging and potentially multidrug-resistant fungal pathogen. Due to their intrinsically biological activity versatility, five derivatives compounds showed leishmanicidal inhibitory activity between 15.0 and 20.0% at concentrations of 20 and 40.0 µg mL-1. Among these compounds the derivative 13a showed best IC50 value of 63.34 µg mL-1 (182.86 µM). CONCLUSION The preliminary and promising results suggest that bistriazole derivatives, especially compound 13a, could represent an innovative scaffold for further studies and development of new antifungal and anti-parasitic drug candidates.

Abstract
Dibenzo[24]crown-8 (DB24C8) forms rotaxanes with a linear molecule having a dialkylammonium group and a triazole group as well as with the acetylation product of a cationic axle molecule. The former cationic rotaxane is stabilized by multiple intermolecular hydrogen bonds between the NH2+ and oxyethylene groups. The neutral rotaxane contains the macrocycle in the vicinity of the terminal aryl group. The co-conformation of both the cationic and neutral rotaxanes can be fixed by coordination of the triazole group of the axle molecule to PtCl2 (dmso)2 . A 1 H NMR spectroscopic study on the thermodynamics of the Pt coordination revealed a larger association constant for the rotaxanes than for the corresponding axle molecules and a larger value for the neutral rotaxane than for the cationic rotaxane.

Abstract
The Cu(I)-catalyzed azide-alkyne cycloaddition reaction, also known as click chemistry, has become a useful tool for the facile formation of 1,2,3-triazoles. Specifically, the utility of this reaction has been demonstrated by the synthesis of structurally diverse bi- and bis-1,2,3-triazoles. The present review focuses on the synthesis of such bi- and bistriazoles and the importance of using copper-promoted click chemistry (CuAAC) for such transformations. In addition, the application of bitriazoles and the related CuAAAC reaction in different fields, including medicinal chemistry, coordination chemistry, biochemistry, and supramolecular chemistry, have been highlighted.

Abstract
A new rotaxane containing the 3-amido-phenyl-triazolium group incorporated into the interlocked structure's axle component has been prepared by a chloride anion templated clipping strategy. Proton NMR titration experiments reveal that the interlocked host displays a high degree of halide anion recognition in competitive 1 : 1 CDCl3-CD3OD solvent mixture. Chloride and bromide anions are bound strongly and selectively, with negligible complexation of the larger, more basic oxoanions, acetate and dihydrogen phosphate being observed. Density functional theory calculations on the related axle motifs 3-amido-phenyl-triazolium, pyridinium bis-triazole and pyridinium bis-amide were performed, and indicate that the new rotaxane axle motif displays much weaker oxoanion binding than the pyridinium based systems.

Abstract
Since the start of this millennium, remarkable progress in the binding and sensing of anions has been taking place, driven in part by discoveries in the use of hydrogen bonding, as well as the previously under-exploited anion-π interactions and halogen bonding. However, anion supramolecular chemistry has developed substantially beyond anion recognition, and now encompasses a diverse range of disciplines. Dramatic advance has been made in the anion-templated synthesis of macrocycles and interlocked molecular architectures, while the study of transmembrane anion transporters has flourished from almost nothing into a rapidly maturing field of research. The supramolecular chemistry of anions has also found real practical use in a variety of applications such as catalysis, ion extraction, and the use of anions as stimuli for responsive chemical systems.
