Synthesis of 5-substituted 3-mercapto-1,2,4-triazoles via Suzuki–Miyaura reaction
摘要:
3-Bromo- and 3-iodo-N,S-dibenzyl-5-mercapto-1,2,4-triazoles were prepared and demonstrated as versatile building blocks for Suzuki-Miyaura cross-coupling with aryl, heteroaryl, and vinyl boronic acid derivatives. Deprotection of the resulting coupling products provided 5-substituted-3-mercapto-1,2,4-triazoles in good overall yields. This represents a novel and convenient approach for the introduction of a 3-mercapto-1,2,4-triazole substructure into target compounds. (c) 2013 Elsevier Ltd. All rights reserved.
In this study, we introduced 1, 2, 4-triazole groups into panaxadiol (PD) to obtain 18 panaxadiol triazolederivatives. Five cancer cells and one normal cell were evaluated for cytotoxicity by MTT assay. The results showed that most of the derivatives could inhibit cancer cell proliferation, and the anti-proliferative activity of compound A1 was the most significant. For HepG-2 cells, the IC50 value

Thiatetraazaindenone derivatives were synthesized by reaction of 3-substituted 1,2,4-triazole-5-thiols with N-substituted N-chloromethyl carbamoyl chlorides. A series of thiatriazafluorenone derivatives were also prepared by reaction of benzimidazole derivatives with the same substrate. Some of the new compounds show fungicidal, herbicidal, and insecticidal activity.

SecA, a key component of the bacterial Sec‐dependent secretion pathway, is an attractive target for the development of new antimicrobial agents. Through a combination of virtual screening and experimental exploration of the surrounding chemical space, we identified a hit bistriazole SecAinhibitor, SCA‐21, and studied a series of analogues by systematic dissections of the core scaffold.
