Design, synthesis, anticancer and antioxidant activities of amide linked 1,4-disubstituted 1,2,3-triazoles

To explore anticancer and antioxidant agents with improved potency, we synthesized a series of amide linked 1,4-disubstituted 1,2,3-triazoles through click chemistry approach. The structure of synthesized triazoles were characterized by- FTIR, H-1 NMR, C-13 NMR spectroscopy and HRMS. All the synthesized compounds were screened for their anticancer activity against four different cell lines- PC3 (prostate cancer), A549 (lung cancer), MIAPACA (liver cancer), Fr2 (Breast epithelial), reflecting compounds 7e and 7f to possess good activity. The antioxidant activity was evaluated by using stable free radical 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay and compound 7d showed promising activity having IC50 value 1.61 mu g/ml. Molecular docking studies of compounds 7e and 7f was carried out in active site of human epidermal growth factor receptor 2 revealed high binding affinities and within toxicity limits. The experimental results were in good agreement with docking studies. In-silico ADME studies of synthesized compounds also have good dispositional profile and are patient compliant, may be potential future candidates for anticancer treatment. (C) 2020 Elsevier B.V.

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.

Fluorinated Triazole Foldamers: Folded or Extended Conformational Preferences

Fluorinated peptidomimetic foldamers are still in their infancy. We report here the easy access to fluorinated triazolamers based on 2-amino-3,3,3-trifluoropropyl-1,4-triazolyl acetic acid (CF3-1,4-Tz) and on aminomethyl-1,4-triazolyl-difluoroacetic acid (1,4-Tz-CF2). Both CF3-1,4-Tz and 1,4-Tz-CF2 amino acids were efficiently prepared by copper(I)-catalyzed Huisgen 1,3-dipolar cycloaddition. Their conformational preferences were studied by 2D NMR analyses and molecular dynamic simulations. Foldamers based on CF3-1,4-Tz amino acids are capable of adopting short multi-stranded beta-sheet-like structures that are maintained by electrostatic interactions between the triazole proton and N2 atom of neighboring subunits. On the contrary, foldamers based on 1,4-Tz-CF2 units adopt elongated beta-strand-like structures, stabilized by electrostatic interaction between fluorine atoms and their neighboring protons.

The Three-Component Synthesis of 4-Sulfonyl-1,2,3-triazoles via a Sequential Aerobic Copper-Catalyzed Sulfonylation and Dimroth Cyclization

4-Sulfonyl-1,2,3-triazole scaffolds possess promising bioactivities and applications as anion binders. However, these structures remain relatively unexplored and efficient synthetic procedures for their synthesis remain desirable. A practical room-temperature, aerobic copper-catalyzed three-component reaction of aromatic ketones, sodium sulfinates, and azides is reported. This procedure allows for facile access to 4-sulfonyl-1,5-disubstituted-1,2,3-triazoles in yields ranging from 34 to 89%. The reaction proceeds via a sequential aerobic copper(II)chloride-catalyzed oxidative sulfonylation and the Dimroth azide-enolate cycloaddition.

Thioether-terminated triazole-bridged covalent organic framework for dual-sensitive drug delivery application

A novel thioether-terminated triazole bridge-containing covalent organic framework (TCOF) was constructed via a simple click chemistry between alkyne and azide monomers for dual-sensitive [pH and glutathione (GSH)] anticancer drug delivery systems. The synthesized TCOFs were crystalline in nature with a pore size of approximately 10-30 nm, as confirmed by powder X-ray diffraction spectroscopy and Brunauer-Emmett-Teller technique. Owing to the flexible nature of the synthesized COF, polyethylene glycol (PEG) modification was easily performed to yield a stable TCOF (TCOF-PEG) colloidal solution. Doxorubicin (DOX)-loaded TCOF-PEG (TCOF-DOX-PEG) exhibited sensitivity to lysosomal pH 5 and GSH environments. DOX release was four times higher under GSH environment (relative to pH 7.4) and three times higher under pH 5 condition because of the dynamic nature of triazole. In contrast, DOX-loaded COF without the triazole ring (I-COF) did not show any significant drug release in pH 7.4 and acidic pH; however, drug release was observed in GSH environment. MTT drug internalization data demonstrated sustained release of DOX from TCOF-DOX-PEGs. Finally, we demonstrated the utility of TCOF-PEG as an in vitro drug delivery system in HeLa cells. TCOF-DOX-PEG exhibited time-dependent release of DOX followed by internalization. Thus, the novel TCOF system reported here opens a new window in COF research for sensitive drug carrier systems.

Waste-minimized synthesis of C2 functionalized quinolines exploiting iron-catalysed C-H activation

Herein we present an efficient and regioselective iron-catalyzed methodology for the external oxidant-free functionalization of quinoline-N-oxides. The protocol, based on the use of inexpensive and easily accessible FeSO4, showed broad applicability to a wide range of substrates. An additional green feature of this synthetic methodology is H2O being the only by-product. Experimental and computational investigations provide support to a mechanism based on a facile C-H activation event. The green efficiency of the process has also been carefully assessed using: (i) metrics related to the synthetic process (AE, Yield, 1/SF, MRP and RME); (ii) safety/hazard metrics (SHZI and SHI); and (iii) metrics related to the metal used as the catalyst (Abundance, OEL and ADP). In addition to the many advantages of this protocol related to the green iron catalyst used and the safety/hazard features of the process, an E-factor value of ca. 0.92 (84 to >99% reduction compared to known protocols) evidently confirms the sustainable efficiency of the procedure presented. Practical utility has also been demonstrated by performing the reaction efficiently on a multi-gram scale.

XPS analysis confirms the presence of Cu as Cu1+ and Cu2+ by the effect of the linker in IL@CuFe(2)O(4)LTyr-TiO2/TiTCIL. It provides an eco-friendly procedure with several advantages such as operational simplicity, water as the solvent, short reaction time, easy workup and excellent yields in the synthesis of 1,4-disubstituted-1,2,3-triazoles via Click reaction. The catalyst showed recyclability up to seven runs in Click reaction and the recycled catalyst was also characterized by HR-TEM, FEG-SEM and XPS. In Click reaction, one single crystal of 1-benzyl-4-phenyl-1H-1,2,3-triazole was grown. Its energetic features, non-covalent interactions, molecular electrostatic potential surfaces, and packing arrangement were calculated by using the B3LYP-D3/def2-TZVP level of theory and the Bader’s quantum theory of Atoms in molecules (QTAIM). Moreover, IL@CuFe(2)O(4)LTyr-TiO2/TiTCIL also displayed good photocatalytic activity in the degradation of methylene blue dye in visible light. (c) 2020 Elsevier B.V. All rights reserved.
