A triazole is a heterocyclic compound featuring a five-membered ring of two carbon atoms and three nitrogen atoms with molecular formula C 2 H 3 N 3. Triazoles exhibit substantial isomerism , depending on the positioning of the nitrogen atoms within the ring. Many triazoles are versatile, biologically active compounds commonly used as fungicides and plant retardants. However, triazoles are also useful in bioorthogonal chemistry , because the large number of nitrogen atoms causes triazoles to react similar to azides. Lastly, the many free lone pairs in triazoles make them useful as coordination compounds, although not typically as haptic ligands. There are four triazole isomers, which are conventionally divided into two pairs of tautomers. 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.

Triazole

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. However, adverse events such as hepatotoxicity and hormonal problems lead to a careful revision of the azole family to obtain higher efficacy with minimum side effects. This review focuses on the structural features, synthesis, and notable therapeutic applications of triazoles and related compounds. The name triazole was first coined by Bladin in to assign the five-membered three nitrogen—containing heterocyclic aromatic ring system having molecular formula C 2 H 3 N 3 Bladin, After the discovery of triazole, its chemistry was developed gradually and speeded up with the establishment of several facile and convenient synthetic techniques along with its versatile interaction with biological systems Aneja et al.

Selenium dioxide-mediated synthesis of 1,2,4-triazole and the speculative mechanism, triazole. The name triazole triazole sanalika coined by Bladin in to assign the five-membered three nitrogen—containing heterocyclic aromatic ring system having molecular formula C 2 H triazole N 3 Bladin, Copper-mediated synthesis of 1, 2, 3-triazoles from N-tosylhydrazones and anilines.

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.

Triazoles are a family of five-membered rings that contain three nitrogen atoms and two double bonds.

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. Triazole is an important nitrogen heterocyclic compound, containing three nitrogen atoms and two carbon atoms.
