Among the nitrogen-containing heterocyclic compounds, triazoles emerge with superior pharmacological applications. Structurally, there are two types of five-membered triazoles: 1,2,3-triazole and 1,2,4-triazole. Due to the structural characteristics, both 1,2,3- and 1,2,4-triazoles are able to accommodate a broad range of substituents electrophiles and nucleophiles around the core structures and pave the way for the construction of diverse novel bioactive molecules. Both the triazoles and their derivatives have significant biological properties including antimicrobial, antiviral, antitubercular, anticancer, anticonvulsant, analgesic, antioxidant, anti-inflammatory, and antidepressant activities. These are also important in organocatalysis, agrochemicals, and materials science. Thus, they have a broad range of therapeutic applications with ever-widening future scope across scientific disciplines.

Triazole is an important heterocyclic moiety that occupies a unique position in heterocyclic chemistry, due to its large number of biological activities. It exists in two isomeric forms i. The structures of all synthesized compounds were characterized by physicochemical properties and spectral means IR and NMR. The synthesized compounds were evaluated for their in vitro antimicrobial activity against Gram-positive B. In-vitro antioxidant and anti- urease screening was done by DPPH assay and indophenol method, respectively. Triazole is an N-bridged aromatic heterocyclic compound that received a considerable attention in recent years due to their biological activities [ 1 ]. Triazole exists in two isomeric forms such as 1,2,4-triazole and 1,2,3-triazole [ 4 ]. The SAR studies of triazole derivative reveals that substitution on positions 3, 4 and 5 of triazole ring can be varied but the greatest changed in physicochemical properties and biological profile is exerted by the groups attached to the nitrogen atom at the 4th position [ 3 ].

Amidines as nitrogen source Amidine was widely used as an organic catalyst and ligand for the formation of nitrogen—carbon bonds due to the reactivity of nucleophilic nitrogen atoms.

Triazole

Triazole, comprising three nitrogen atoms and two carbon atoms, is divided into two isomers 1,2,3-triazole and 1,2,4-triazole. Compounds containing a triazole are one of the significant heterocycles that exhibit broad biological activities, such as antimicrobial, analgesic, anti-inflammatory, anticonvulsant, antineoplastic, antimalarial, antiviral, antiproliferative, and anticancer activities. A great quantity of drugs with a triazole structure has been developed and proved, for example, ketoconazole and fluconazole. Given the importance of the triazole scaffold, its synthesis has attracted much attention. This review summarizes the synthetic methods of triazole compounds from various nitrogen sources in the past 20 years.

In , Yu et al. Explanation of pictograms. Another molecular amidine 4 undertook the second attack of 3 with an intramolecular nucleophilic cyclization and followed oxidation to generate the final 1,3,5-triazine compounds. Structures of isomeric triazoles. CuAAC is well known for its inexpensive catalytic systems and generates highly regioselective products Rostovtsev et al. These inherent properties of triazole compounds have established them as key chromophores with immense medicinal value and attract scientists of all disciplines, including chemical, agricultural, supramolecular, pharmaceutical, polymer, and materials sciences Chang et al. The use of ILs as nontoxic benign solvents can improve the reaction rate and regioselectivity of the cycloaddition reaction Javaherian et al.

Triazoles are a family of five-membered rings that contain three nitrogen atoms and two double bonds. Catalysts 8, Physicochemical characterization of synthesized derivatives T 1 — T

Among the nitrogen-containing heterocyclic compounds, triazoles emerge with superior pharmacological applications.

RSC Adv. Imidates as nitrogen source Imidates are helpful precursors of triazoles, which have been extensive wielded in this field. S2CID All authors approved the submitted version and revised version. In the 1,2,3-triazoles , the three nitrogen atoms are adjacent; in the 1,2,4-triazoles , an interstitial carbon separates out one nitrogen atom. This past February, researchers reported that it may limit the effects of COVID by attacking a specific enzyme in the virus. Rationally, A category of anti urease or urease inhibitory drugs was developed for curing the urease caused disease by inhibiting urease enzymes. The relative percent of DPPH scavenging activity was calculated according to the following equation:. Netherlands: Springer. The synthesis method of 1,2,4-triazole mainly uses amidine, amide, amidine hydrazone, aryl diazonium salt, and hydrazone as nitrogen sources.
