Facile synthesis of 6-aryl-3-pyridyl-1,2,4-triazines as a key step toward highly fluorescent 5-substituted bipyridines and their Zn(II) and Ru(II) complexes
摘要:
A wide series Of Substituted bipyridines were obtained through the synthesis of 1,2,4-triazines and their aza Diels-Alder reactions. The reported method facilitates the synthesis of functionally diverse bipyridines that provides fine-tuning of photophysical properties of new ligands and their Zn(II) and Ru(II) complexes. Some of substituted bipyridines exhibit 'off-on' fluorescence response toward Zn 2 cations. (C) 2008 Elsevier Ltd. All rights reserved.

-imidazole-5-carboxylic acid derivatives that presented excellent in vitro xanthineoxidase inhibitory potency. As a continuation study, a series of 1-hydroxy-2-phenyl-1H-imidazole derivatives containing a pyridine moiety (4a-g and 5a-g) at the 4-position was designed and synthesized. Evaluation of in vitro xanthineoxidase inhibition demonstrated that the 4a-g series was more potent than the 5a-g
