substitution on certain chosen ring systems, and (d) combinations of the aforementioned variants. Preliminary biologicalactivity screening indicated that N-(dialkylaminoethyl)imides of the 3,6-dinitro- and 3,6-diamino-1,8-naphthalic acid system possessed prominent antileukemia and antimelanoma activity in both in vitro and in vivo experimental tumor systems.

higher emission in polar than in apolar environments. Excited-state dynamics studies, TD-DFT calculations, X-ray and NMR support the existence of a folded conformation for the 2-(dimethylamino)ethyl chain upon the imide ring in apolar solvents, where the dimethylamino group would quench the fluorescence by a PET effect, while in polar solvents the chain has an extended conformation, where the PET is

dual-color visualization of cellapoptosis. NA-S was designed to be polarity sensitive, bearing alkalescence group, and with DNA affinity. In living cells, NA-S targeted the lysosomes to give blue fluorescence, which translocated into the nucleus during cellapoptosis to give green emission. Thereby, the cellapoptosis could be visualized with NA-S in dual-emissive manner. With the unique probe, the cell
细胞凋亡的可视化是一项关键任务,在生物学、病理学和生物医学的基础研究中起着核心作用。双发射荧光探针是研究细胞凋亡的理想分子工具,但很少报道。在此,利用溶酶体和细胞核之间的极性差异,开发了一种易位型荧光探针 (NA-S) 用于细胞凋亡的双色可视化。NA-S 被设计为极性敏感,带有碱性基团,并具有 DNA 亲和力。在活细胞中,NA-S 靶向溶酶体产生蓝色荧光,蓝色荧光在细胞凋亡过程中转位到细胞核中,发出绿色发射。因此,细胞凋亡可以用 NA-S 以双发射方式可视化。使用独特的探针,已成功观察到氧化应激、紫外线照射、鱼藤酮、秋水仙碱和紫杉醇诱导的细胞凋亡。
A ratiometric fluorescent probe for in vivo tracking of alkaline phosphatase level variation resulting from drug-induced organ damage
The ratiometric fluorescent probe discussed herein can detect ALP levels in clinical serum samples, and spatially map endogenous ALP level variations, which occur as a result of drug induced organ damage.
