在吲哚环的N原子上具有甲基,乙基或对羧基苄基的三种七甲叉吲哚花青的合成基础上,通过丁胺,牛磺酸或苄胺与吲哚花青反应用氮取代氯来设计和合成了九种新型氨基衍生物。 。所得产物通过SiO 2柱色谱法纯化,并通过ESI-MS和1进行确认。1 H NMR。与母体相比,氨基衍生物表现出蓝移,较大的斯托克斯位移和较强的荧光强度,这主要与氨基衍生物中氨基取代基的供电子能力有关。氨基取代基的更强的供电子能力使最大吸收波长显示出更大的蓝移。
of organic synthesis technology and the development of fluorescent probe, more and more fluorescent probes with excellent performance and versatility are required, so as to better realize their application value. High sensitivity, high selectivity, targetable and fast response NIRfluorescenceprobes are still needed for hydrogen sulfide precise detection. In this study, phenol containing 2, 4-dinitro

A NIR fluorescent probe tracing norepinephrine exocytosis and depression occurrence at the cellular level revealed that norepinephrine exocytosis rather than the inherent intracellular concentration was related with depression.
