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.

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 ].

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.

Treatment with triazoles, a class of antifungal medicine, has greatly improved survival, but resistant infections are increasingly reported worldwide. Of particular concern are resistant infections that appear to be related to environmental use of triazole fungicides in agriculture rather than to previous patient use of antifungal medicine. Use of triazole fungicides in the environment increased more than fourfold from to in the United States, amplifying concerns about resistant A. CDC has developed a plan to address the growing threat of triazole-resistant A. This plan includes efforts to address knowledge gaps in areas such as the occurrence of resistant cases and community practice, engaging with stakeholder partners, and sharing information about the threat and ways that stakeholders can help prevent further resistance.

Tetrahedron 60 19 , — Advances in synthetic approach to and antifungal activity of triazoles. All of the triazoles are planar and aromatic. Lebeau, A. Nagarajan, R. Trimethylsilyl azide as nitrogen source As an important nitride, trimethylsilyl azide is often used to synthesize various nitrogen-containing compounds. The advantages were that the substituents on amide hydrazone and anhydride had good tolerance during optimized conditions, and the HClO 4 -SiO 2 catalyst could be recycled continuously for at least three times Scheme 15A. Numerous medicines containing triazole moiety available in market Fig. This article was submitted to Medicinal and Pharmaceutical Chemistry, a section of the journal Frontiers in Chemistry. In addition, 5-mercapto-1,2,4-triazoles 46a-c can be used as a scaffold for the preparation of S -substituted triazoles with antiproliferative activities in colorectal cancer Mioc et al. Systemic: griseofulvin. The percentage inhibition of urease enzyme was calculated by using following formula:. Reinvestigation of the synthesis and evaluation of [N-methylC]vorozole, a radiotracer targeting cytochrome P aromatase. Table 6 Anticancer screening results of the synthesized compounds T 1 — T

Open access peer-reviewed chapter. Among nitrogen-containing heterocyclic compounds, 1,2,3-triazoles are privileged structure motif and received a great deal of attention in academics and industry.

Tetrahedron 74 , — The main sources of palmitic acid are palm oil, olive oil, meats, cheese, cocoa butter, breast milk and dairy products [ 18 ]. The adaptability of various aryl-substituted azides and cinnamic acid substrates was investigated, and it was found that various functional groups including halogen, nitro group, and cyanide group could be applied under the reaction conditions Scheme 8A. As an instance, a group of researchers discovered that icotinib-1,2,3-triazole derivatives 58 Supplementary Figure S7 exhibited remarkable inhibitory activity against indoleamine 2,3-dioxygenase 1 IDO1 with very low IC 50 values 0. In , Yu et al. Goss PE. Many triazoles have antifungal effects: the triazole antifungal drugs include fluconazole , isavuconazole , itraconazole , voriconazole , pramiconazole , ravuconazole , and posaconazole and triazole plant-protection fungicides include epoxiconazole , triadimenol [ de ] , myclobutanil , propiconazole , prothioconazole , metconazole , cyproconazole , tebuconazole , flusilazole and paclobutrazol. The substitution of of p -aldehyde and o -hydroxy group on the aromatic ring may enhance the anticancer activity against HCT cells Fig. A Synthesis of 1,5-disubstituted-1,2,3-triazoles. CAS Reg. The scavenging effect increased with the increasing concentrations of sample compounds. The complexation of copper intermediate with phenyl phenylethynyl -selane and -azide, which underwent oxidative cyclization, turned into products under air atmosphere to finish the reaction.
