Theoretical insights into the synthesis reaction mechanism of 1,2,3-triazole based on sakai reaction

Sakai reaction is an important method to synthetize 1,2,3-triazole by the addition of alpha, alpha-dichlorotosylhydrazones and amines. However, the difficulty of introducing the 1,2,3-triazole ring is often affected by the type of amine reagent. More calculation results and detailed mechanisms are used to screen which amine is more suitable for the Sakai reaction. In this study, the DFT calculations were carried out to study the reaction mechanism of Sakai reaction. Depending on the type of amines, two different paths for Sakai reaction were revealed by our calculations. For the triazolamine, an H atom must transfer from the amines to the diazine synchronously when the new C-N bond is formed. The transformation from trans- to cis- is necessary for the intermediate vinyldiazine. For aniline, the amine molecule can combine with trans-vinyldiazine directly without an H transfer due to the formation of a structure that is similar to NH4+ ion. (C) 2020 Elsevier Ltd.

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.
