N-Fused heterocycles have attracted much interest since they are widely present in naturally occurring alkaloids and synthetic compounds with a broad spectrum of biological activities.
Natural products that target RNA include the macrolides(e.g.,erythromycin,clarythromycin,and azithromycin)and the aminoglycosides(e.g.,tobramycin and gentamicin).
汞是造成环境污染的主要重金属离子之一,在浓度很低时对生物体就表现出极强的生理毒性。且汞易经生物富集作用最终转移到人类体内,且无法通过自身代谢作用排出体外,严重危害人类的身体健康。因此,对生物体和环境中汞的分析检测一直是人们非常关注的问题,建立快速、高效的汞离子检测方法在生命科学、医学、环境保护等领域中具有重大意义。
