rhodamine, tetramethylrhodamine, BODIPY, dansyl, and nitrobenzoxadiazole (NBD)). On the isolated guinea pig ileum and in a Ca(2+) assay on U373MG human glioblastoma cells the highest H(1) antagonistic activities were found in 5- and 6-carboxyfluorescein labeled compounds with hexa- and octamethylene spacers and in an analogous NBD-aminohexanoyl derivative (pA(2) or pK(B) values in the range: 8.3-9.0; compared

The conjugate of the fluorescent dye 4,4,-difluoro-1,3,5,7-tetramethyl-4-bora-3a,4a-diaza-s-indasten-8-propionic acid (BODIPY) with N2,N4,N6-trimethylmelamine was obtained. This compound was shown to generate covalent crosslinks between DNA strands in vitro in the presence of formaldehyde.
荧光染料 4,4,-difluoro-1,3,5,7-tetramethyl-4-bora-3a,4a-diaza-s-indasten-8-propionic acid (BODIPY) 与 N2,N4,N6 的共轭物得到-三甲基三聚氰胺。在存在甲醛的情况下,该化合物显示出在体外 DNA 链之间产生共价交联。

the 18F‐labeled BODIPY‐FL fluorophore has emerged as an important platform, but little is known about alternative 18F‐labeling strategies or labeling on red‐shifted fluorophores. In this study we explore acid‐catalyzed 18F/19F exchange on a range of commercially available N‐hydroxysuccinimidyl ester and maleimide BODIPY fluorophores. We show this method to be a simple and efficient 18F‐labeling strategy
含氟荧光染料是正电子发射断层扫描成像化合物的重要验证剂,因为它们可以通过荧光成像在细胞中轻松验证。特别是18 F 标记的 BODIPY-FL 荧光团已成为一个重要的平台,但对替代18 F 标记策略或红移荧光团的标记知之甚少。在这项研究中,我们探索了一系列市售N-羟基琥珀酰亚胺酯和马来酰亚胺 BODIPY 荧光团的酸催化18 F/ 19 F 交换。我们证明这种方法是一种简单有效的18多种荧光化合物的 F 标记策略,包括 BODIPY 修饰的 PARP-1 抑制剂和胺和硫醇反应性 BODIPY 荧光团。

Cannabinoid receptor type 2 (CB2R) agonists have therapeutic potential for the treatment of (neuro)inflammatory diseases. Fluorescentprobes enable the detection of CB2R in relevant cell types and serve as a chemical tool in cellular target engagement studies. Here, we report the structure-based design and synthesis of a new CB2R selective fluorescentprobe. Based on the cryo-EM structure of LEI-102
