Identification of 8-Azaguanine Biosynthesis–Related Genes Provides Insight Into the Enzymatic and Non-enzymatic Biosynthetic Pathway for 1,2,3-Triazole

open access: yesFrontiers in Bioengineering and Biotechnology, 2020
8-Azaguanine (1) is a special 1,2,3-triazole containing natural product that possesses potent antibacterial and antitumor activities. In the present study, the entire 8-azaguanine biosynthetic gene cluster was located from Streptomyces CGMCC4.1633 ...

Biochemical and in silico inhibition of bovine and human carbonic anhydrase-II by 1H-1,2,3-triazole analogs

open access: yesFrontiers in Chemistry, 2022
A series of 1H-1,2,3-triazole analogs (7a–7d and 9a–9s) were synthesized via “click” chemistry and evaluated for in vitro carbonic anhydrase-II (bovine and human) inhibitory activity. The synthesis of intermediates, 7a and 7c, was achieved by using (S)-(-

1,2,3-Triazoles

open access: yes, 2008
Rapid progress in the synthetic application of benzotriazole derivatives in the last 20 years has resulted in over 1000 scientific papers on the subject. This fact is reflected in Section 5.01.7, which involves almost a half of the volume of this chapter. The section is arranged according to hybridization of the C-α atom and atomic numbers of the atoms

Fullerenyl-1,2,3-Triazoles: Synthesis and Cytotoxic Activity

open access: yesThe 25th International Electronic Conference on Synthetic Organic Chemistry, 2021
Through the reaction of fullerenylazide with terminal acetylenes, previously undescribed 1-butyl-2-triazolylfullerenes, in which the heterocyclic fragment was directly attached to the fullerene backbone, were synthesized for the first time. Water-soluble complexes of the synthesized adducts of fullerene with polyvinylpyrrolidone showed a high cytotoxic

Radiosynthesis of 5-[18F]Fluoro-1,2,3-triazoles through Aqueous Iodine–[18F]Fluorine Exchange Reaction

open access: yesMolecules, 2021
In this report, a simple and efficient process to achieve fluorine-18-labeled 1,2,3-triazole is reported. The heteroaromatic radiofluorination was successfully achieved through an iodine–fluorine-18 exchange in an aqueous medium requiring only trace ...

Syntheses and Applications of 1,2,3-Triazole-Fused Pyrazines and Pyridazines

open access: yesMolecules, 2022
Pyrazines and pyridazines fused to 1,2,3-triazoles comprise a set of heterocycles obtained through a variety of synthetic routes. Two typical modes of constructing these heterocyclic ring systems are cyclizing a heterocyclic diamine with a nitrite or reacting hydrazine hydrate with dicarbonyl 1,2,3-triazoles.

Design, Synthesis and Anticancer Screening of Novel Benzothiazole-Piperazine-1,2,3-Triazole Hybrids

open access: yesMolecules, 2018
A library of novel regioselective 1,4-di and 1,4,5-trisubstituted-1,2,3-triazole based benzothiazole-piperazine conjugates were designed and synthesized using the click synthesis approach in the presence and absence of the Cu(I) catalyst. Some of these 1,
