Abstract
AIMS AGEs augment inflammatory responses by activating inflammatory cascade in monocytes, and hence lead to vascular dysfunction. The current study aims to study a plausible role and mechanism of a new library of indole-tethered 1,2,3-triazoles 2-13 in AGEs-induced inflammation. MATERIAL AND METHODS Initially, the analogs 2-13 were synthesized by cycloaddition reaction between prop-2-yn-1-yl-2-(1H-indol-3-yl) acetate (1) and azidoacetophenone (1a). In vitro glycation, and metabolic assays were employed to investigate antiglycation and cytotoxicity activities of new indole-triazoles. DCFH-DA, immunostaining, Western blotting, and ELISA techniques were used to study the reactive oxygen species (ROS), and pro-inflammatory mediators levels. KEY FINDINGS Among all the synthesized indole-triazoles, compounds 1-3, and 9-13, and their precursor molecule 1 were found to be active against AGEs production in in vitro glucose- and methylglyoxal (MGO)-BSA models. Compounds 1-2, and 11-13 were also found to be nontoxic against HEPG2, and THP-1 cells. Our results show that pretreatment of THP-1 monocytes with selected lead compounds 1-2, and 11-13, particularly compounds 12, and 13, reduced glucose- and MGO-derived AGEs-mediated ROS production (P < 0.001), as compared to standards, PDTC, rutin, and quercetin. They also significantly (P < 0.001) suppressed NF-ĸB translocation in THP-1 monocytes. Moreover, compounds 12, and 13 attenuated the AGEs-induced COX-2 protein levels (P < 0.001), and PGE2 production (P < 0.001) in THP-1 monocytes. SIGNIFICANCE Our data revealed that the indole-triazoles 12, and 13 can significantly attenuate the AGEs-induced proinflammatory COX-2 levels, and associated PGE2 production by suppressing AGE-ROS-NF-Kβ nexus in THP-1 monocytes. These compounds can thus serve as leads for further evaluation as treatment to delay early onset of diabetic complications.

Synthesis, Molecular Docking and In Vivo Biological Evaluation of Iminostilbene Linked 1,2,3-Triazole Pharmacophores as Promising AntiAnxiety and Anti-Inflammatory Agents. Med Chem 2021; 18:260-272. [PMID: 34102985 DOI: 10.2174/1573406417666210608141746] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2020] [Revised: 01/15/2021] [Accepted: 01/21/2021] [Indexed: 11/22/2022]
Abstract
BACKGROUND Iminostilbene and 1,2,3-triazole ring containing compounds are considered as beneficial substrates in drug design. OBJECTIVES This study was aimed at the synthesis of novel series of iminostilbene linked 1,2,3- triazole pharmacophores (7c-n) by Cu(I) catalyzed 1,3 dipolar cycloaddition reaction between 5- (Prop-2-yn-1-yl)-5H-dibenzo[b,f]azepine (7b) and various substituted azidobenzene derivatives (3cn). METHODS The chemical structures of compounds were confirmed by 1 H NMR, 13C NMR, LC-MS and molecular docking studies were carried out through HEX docking software. RESULTS The in vivo anti anxiety capacity of the compounds was evaluated by using "elevated plus maze" (EPM), anxiety model. The results exhibited that compounds (7d, 7e, 7j and 7k) have a higher anti anxiety effect close to diazepam. The anti-inflammatory activities of the synthesized compounds were evaluated by "Carrageenan-induced rat paw edema" model, compounds (7b, 7c, 7d, 7f, and 7j) demonstrated statistically significant inflammatory activity. Molecular docking analysis revealed that compounds (7d, 7e and 7j) bound to GABA(A) proteins show more efficiency when compared to the other analogues in the series. CONCLUSION These results suggest that compounds (7b, 7c, 7d, 7e, 7f, and 7j) can be considered as novel candidates for anti-anxiety and anti-inflammatory agents. Moreover, docking method was used to elucidate anti-anxiety effect of compounds. This study furnished insight into the molecular interactions of synthesized compounds with their physiological targets, and the potential to develop bioactive heterocyclic compounds.

Abstract
The review lays emphasis on the significance of 1,2,3-triazoles synthesized via CuAAC reaction having potential to act as anti-microbial, anti-cancer, anti-viral, anti-inflammatory, anti-tuberculosis, anti-diabetic, and anti-Alzheimer drugs. The importance of click chemistry is due to its 'quicker' methodology that has the capability to create complex and efficient drugs with high yield and purity from simple and cheap starting materials. The activity of different triazolyl compounds was compiled considering MIC, IC50, and EC50 values against different species of microbes. In addition to this, the anti-oxidant property of triazolyl compounds have also been reviewed and discussed.

Abstract
In the present study, a series of new carbazole linked 1H-1,2,3-triazoles (2-27) were synthesized via click reaction of N-propargyl-9H-carbazole (1) and azides of appropriate acetophenones and heterocycles. Synthesized carbazole triazoles including 7, 9, 10, 19, 20, and 23-26 (IC50=0.8±0.01-100.8±3.6μM), exhibited several folds more potent α-glucosidase inhibitory in vitro activity as compared to standard drug, acarbose. Compounds 2-5, 7-13, and 17-27 did not show any cytotoxicity against 3T3 cell lines, except triazoles 6, and 14-16. Among the series, carbazole triazoles 23 (IC50=1.0±0.057μM) and 25 (IC50=0.8±0.01μM) were found to be most active, and could serve as an attractive building block in the search of new non-sugar derivatives as anti-diabetic agents.
