Cell-Permeable Iminocoumarine-Based Fluorescent Dyes for Mitochondria
摘要:
A class of small molecule fluorophores, 2-iminocoumarin-3-carboxamide derivatives, has been developed by a rapid microwave-assisted process. These fluorescent probes are cell membrane permeable with low cytotoxicity and able to selectively stain organelles in living cells.

recyclable heterogeneous ionicliquid catalyst was synthesized. Catalytic activity of the CaO@SiO 2 @AIL hybrid nanoparticles was investigated for synthesis of the pharmaceutically valuable 2-imino-2 H- chromene and dihydropyrano[ c ]chromenederivatives. A wide range of amines and aromatic aldehydes containing either electron-withdrawing or electron-donating substituent were examined using optimized conditions
anthocyanins. A number of compounds with the chromene moiety are known as potential inhibitors of notum pectinacetylesterase, hMAO, aldose reductase, dihydrofolate reductase, TNFa, and acetylcholinesterase. Functionalized 2-iminochromenes have been a subject of increasing interest. A number of these compounds are used as protein tyrosine kinase (PTK) inhibitors, as well as anti-Alzheimer, antimicrobial, anticancer

thiocyanate to provide pyrane 17, thiazine 18, and thiourea 20 derivatives, respectively. Cinnamoyl isothiocyanate was reacted with compound 11 to produce non‐isolable thiourea derivative 21. The newly synthesized compounds have been characterized by infrared (IR), proton nuclear magnetic resonance (1HNMR), and carbon nuclear magnetic resonance (13CNMR) spectral data. The compounds were then evaluated
的杂环化ñ苄基氰乙酰胺1到一个新的系列杂环已经研制成功。因此,1与不同极化π系统的反应分别得到吡咯烷4,吡啶酮6,吡啶8和二氮杂萘10衍生物。N-苄基氰乙酰胺与水杨醛发生缩合反应生成吡喃衍生物11。精制11个精制的吡喃吡喃的13。化合物11与苯甲醛,二硫化碳(环化剂)和硫氰酸铵反应生成吡喃17,噻嗪18和硫脲20衍生物。肉桂酰基异硫氰酸酯与化合物11反应生成不可分离的硫脲衍生物21。新合成的化合物已通过红外(IR),质子核磁共振(1 H NMR)和碳核磁共振(13 C NMR)光谱数据进行了表征。然后评估化合物的抗菌和抗癌活性。
