The impact of fungal allergic sensitization on asthma

Purpose of review Fungal sensitization may contribute to the development of asthma as well as asthma severity. The purpose of this review is to summarize existing knowledge about the pathophysiology, diagnosis, and management of fungal sensitization in asthma and highlight unmet needs and target areas for future investigation. Recent findings Fungal sensitization may occur by a normal or aberrant immune response. Allergic sensitization to fungi is mediated by the adaptive immune response driven by T(H)2 cells and the innate immune response driven by the innate lymphoid cells group 2. Diagnosis of fungal sensitization can be made by either skin prick testing or measurement of fungal-specific serum IgE. Fungal sensitization in asthma has been associated with worse disease severity, including reduced lung function, increased risk of hospitalizations, and life-threatening asthma. A spectrum of disease related to fungal sensitization has been described in asthma including allergic bronchopulmonary mycosis and severe asthma with fungal sensitization (SAFS). The role of antifungals and targeted biologic therapy in asthma with fungal sensitization need further investigation. There is increasing awareness of the contribution of fungal sensitization to asthma severity. However, there are no therapies with proven efficacy. Randomized clinical trials are needed to further investigate the role of biologics.

Facile synthesis, antimicrobial evaluation and molecular docking studies of pyrazole-imidazole-triazole hybrids

A series of eighteen pyrazole-imidazole-triazole hybrid (2-(4-((2-(substituted-1H-pyrazol-1-yl)-4-phenyl1H-imidazol-1-yl)methyl)-1H-1,2,3-triazol-1-yl)-N-(substituted)phenylacetami- de) (6a-6r) are synthesized through click reaction between in situ generated 2-azido-N-substituted acetamide and N-propargylated pyrazole-imidazole derivatives which in turn has been obtained regioselectively from 1(1-H-imidazol-2-yl)-1H-pyrazole and propargyl bromide. The structure of synthesized compounds (6a-6r) was confirmed by various spectroscopic studies (1D and 2D NMR, FT-IR, HRMS) and evaluated for antimicrobial activity. The compound 6m demonstrated excellent potency for A. niger (MIC value 0.0064 mu mol/mL); even better than that of the reference drug Fluconazole (MIC value 0.0112 mu mol/mL). Further, the binding conformation of most active compounds was ascertained by molecular docking studies. (C) 2020 Elsevier B.V. All rights reserved.

Novel Sigma 1 Receptor Antagonists as Potential Therapeutics for Pain Management

The sigma 1 receptor (S1R) is a molecular chaperone protein located in the endoplasmic reticulum and plasma membranes and has been shown to play important roles in various pathological disorders including pain and, as recently discovered, COVID-19. Employing structure- and QSAR-based drug design strategies, we rationally designed, synthesized, and biologically evaluated a series of novel triazole-based SIR antagonists. Compound 10 exhibited potent binding affinity for S1R, high selectivity over S2R and 87 other human targets, acceptable in vitro metabolic stability, slow clearance in liver microsomes, and excellent blood-brain barrier permeability in rats. Further in vivo studies in rats showed that 10 exhibited negligible acute toxicity in the rotarod test and statistically significant analgesic effects in the formalin test for acute inflammatory pain and paclitaxel-induced neuropathic pain models during cancer chemotherapy. These encouraging results promote further development of our triazole-based S1R antagonists as novel treatments for pain of different etiologies.

Identification of 1,2,3-triazole-phthalimide derivatives as potential drugs against COVID-19: a virtual screening, docking and molecular dynamic study

In this work we aimed to perform an in silico predictive screening, docking and molecular dynamic study to identify 1,2,3-triazole-phthalimide derivatives as drug candidates against SARS-CoV-2. The in silico prediction of pharmacokinetic and toxicological properties of hundred one 1,2,3-triazole-phtalimide derivatives, obtained from SciFinderVR library, were investigated. Compounds that did not show good gastrointestinal absorption, violated the Lipinski’s rules, proved to be positive for the AMES test, and showed to be hepatotoxic or immunotoxic in our ADMET analysis, were filtered out of our study. The hit compounds were further subjected to molecular docking on SARS-CoV-2 target proteins. The ADMET analysis revealed that 43 derivatives violated the Lipinski’s rules and 51 other compounds showed to be positive for the toxicity test. Seven 1,2,3-triazole-phthalimide derivatives (A7, A8, B05, E35, E38, E39, and E40) were selected for molecular docking and MFCC-ab initio analysis. The results of molecular docking pointed the derivative E40 as a promising compound interacting with multiple target proteins of SARS-CoV-2. The complex E40-Mpro was found to have minimum binding energy of similar to 10.26 kcal/mol and a general energy balance, calculated by the quantum mechanical analysis, of similar to 8.63 eV. MD simulation and MMGBSA calculations confirmed that the derivatives E38 and E40 have high binding energies of similar to 63.47 +/- 3 and similar to 63.31 +/- 7 kcal/mol against SARS-CoV-2 main protease. In addition, the derivative E40 exhibited excellent interaction values and inhibitory potential against SARCov-2 main protease and viral nucleocapsid proteins, suggesting this derivative as a potent antiviral for the treatment and/or prophylaxis of COVID-19.

Synthesis, structures and magnetic properties of copper(II) complexes with 1,2,3-triazole derivate as ligand: a single-crystal-to-single-crystal transformation from mononuclear to polymeric complex of copper(II)

A new mononuclear complex Cu(tdp)Br-2 center dot MeCN (1, tdp = 2,2 ‘-(1H-1,2,3-triazole-1,4-diyl)dipyridine) has been synthesized, which can transform to a 1D coordination polymer [Cu(tdp)Br-2](n) (2) under ambient conditions through an irreversible single-crystal-to-single-crystal transformation process. The loss of lattice MeCN molecules in 1 was accompanied by the generation of new covalent bonds and an increase in dimensionality from 0 to 1D, leading to a change in magnetic exchange couplings between the adjacent Cu(II) ions. Magnetic susceptibility measurements indicate that 1 exhibits ferromagnetic interactions between the adjacent Cu(II) centers, while the intrachain magnetic interactions between Cu(II) ions are antiferromagnetic within 2.

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.

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.

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.
