For finding novel bioactive compounds with significant antifungal activities, 17 novel benzoxazole derivativescontaining a 1,2,3‐triazole moiety were synthesized by the copper(II) acetylacetonate‐catalyzed cyclization reaction between 2‐aminophenol derivatives and 1H‐1,2,3‐triazole‐4‐carbaldehyde derivatives (4a), which were prepared through three steps using aromatic amine as the starting material

be inherently unstable due to Dimrothrearrangements. This study examined parameters governing the ring-degenerate rearrangement reactions of 1-substituted-4-imino-1,2,3-triazoles, expanding on trends first observed by L'abbé et al. The efficiency of condensation between 4-formyltriazole and amine reactants as well as the propensity of imine products towards rearrangement was each strongly influenced

chemical scaffolds as anthelmintic agents; a series of 1,2,3-triazole–tetrazole conjugates were synthesized. The synthesis of 1,2,3-triazole based tetrazole derivatives has carried out via [2+3]-cycloaddition reaction of triazolyl nitriles with sodium azide. The present design and synthetic strategy offers excellent yields of the products in the presence of [DBU][OAc] under ultrasonic irradiations. The synthesized

The purpose of this study was to prepare various 4-substituted N-phenyl-1,2,3-triazole derivatives using click chemistry. The derivatives were screened in vitro for antimicrobial activity against Mycobacterium tuberculosis strain H37Rv (ATCC 27294) using the Alamar Blue susceptibility test. The activity was expressed as the minimum inhibitory concentration (MIC) in mu g/mL (mu M). Derivatives of isoniazid (INH), (E)-N'-[(1-aryl)-1H-1,2,3-triazole-4-yl)methylene] isonicotinoyl hydrazides, exhibited significant activity with MIC values ranging from 2.5 to 0.62 mu g/mL. In addition, they displayed low cytotoxicity against liver cells (hepatoma HepG2) and kidney cells (BGM), thereby providing a high therapeutic index. The results demonstrated the potential and importance of developing new INH derivatives to treat mycobacterial infections.
