Fluorescent Recognition of Functional Secondary Amines in the Fluorous Phase

Jiang, Le,Tian, Jun,Zhao, Feng,Yu, Shanshan,Shi, Dan,Wang, Xinjing,Yu, Xiaoqi,Pu, Lin

, p. 2533 - 2538 (2019)

In a fluorous solvent (perfluorohexane, FC-72), a perfluoroalkyl-substituted 2-hydroxy-1-naphthaldehyde (1) was found to show greatly enhanced fluorescence when treated with certain functional secondary amines but little fluorescence response was observed with unfunctional amines as well as functional primary and tertiary amines. The study of the reaction of 1 with 2-methylamino ethanol (8) reveals a facile cyclocondensation of the aldehyde group of 1 with this 1,2-amino alcohol to form a 5-membered ring oxazolidine product which turns on the fluorescence. The reaction of 1 with the amino alcohol was found to be more favorable in the fluorous solvent than in a common organic solvent. The use of the fluorous phase-based fluorescence measurement in this work provides a potentially more sensitive as well as selective method in amine sensing.

Fluorous-Phase-Based Chiral Assay with Circular Dichroism Spectroscopy

Xiao, Meng,Yu, Shanshan,Chen, Liming,Huang, Zeng,Wen, Kaili,Xu, Yimang,Zhao, Feng,Yu, Xiaoqi,Pu, Lin

, p. 1413 - 1417 (2017)

A highly fluorinated molecular probe made of a salicylaldehyde derivative is designed and synthesized for the detection of chiral amines in the fluorous phase. When treated with various chiral amines in a fluorous solvent (perfluorohexyl ethanol), this probe shows intense CD signals at wavelengths greater than 400 nm, which has been used to determine the enantiomeric composition of chiral amines, amino alcohols, and amino acids. This is the first example of CD recognition of chiral compounds that is conducted in the fluorous phase. The approach could greatly reduce the undesired interference in the direct assay of asymmetric reactions and catalytic processes.

Modular Synthesis of Di- A nd Trisubstituted Imidazoles from Ketones and Aldehydes: A Route to Kinase Inhibitors

De Toledo, Ian,Grigolo, Thiago A.,Bennett, James M.,Elkins, Jonathan M.,Pilli, Ronaldo A.

supporting information, p. 14187 - 14201 (2019/10/16)

A one-pot and modular approach to the synthesis of 2,4(5)-disubstituted imidazoles was developed based on ketone oxidation, employing catalytic HBr and DMSO, followed by imidazole condensation with aldehydes. This methodology afforded twenty-nine disubstituted NH-imidazoles (23%-85% yield). A three-step synthesis of 20 kinase inhibitors was achieved by employing this oxidation-condensation protocol, followed by bromination and Suzuki coupling in the imidazole ring to yield trisubstituted NH-imidazoles (23%-69%, three steps). This approach was also employed in the synthesis of known inhibitor GSK3037619A.

Artificial photosynthesis of methanol from carbon dioxide and water via a Nile red-embedded TiO2 photocathode

Jia, Yongjian,Xu, Yanjie,Nie, Rong,Chen, Fengjuan,Zhu, Zhenping,Wang, Jianguo,Jing, Huanwang

supporting information, p. 5495 - 5501 (2017/03/22)

The conversion of carbon dioxide into useful chemicals is a prospective strategy for alleviating the greenhouse effect and the depletion of energy. Herein, we report an artificial photosynthetic system composed of a photoanode and a photocathode comprised of NRx@TiO2 functionalized with Nile red via covalent linkage or Pd/NRx@TiO2 with additional palladium nanoparticles. The new Nile red derivatives and organic-inorganic composite electrodes were steadily prepared and well characterized using NMR, HRMS, UV-vis, FTIR, TEM, XPS, XRD and SEM. Methanol and oxygen were the products that could be detected in the liquid and gas phase. The main active species in this artificial photosynthesis system were proven using EPR spectroscopy to be hydroxy radicals releasing O2 gas via H2O2. Moreover, the carbon source of methanol was validated using a 13CO2 labeling experiment; 18O2 was determined to come from H2O using GC-MS. The optimal photoelectrocatalytic CO2 reduction was carried out using Pd/NR2@TiO2 as the working electrode yielding methanol at a rate of 106 μM h?1 cm?2 with high light quantum efficiency (Φcell = 0.95).

Design and synthesis of 2-phenylnaphthalenoids and 2-phenylbenzofuranoids as DNA topoisomerase inhibitors and antitumor agents

Hao, Huilin,Chen, Wang,Zhu, Jing,Lu, Chunhua,Shen, Yuemao

, p. 277 - 287 (2015/09/01)

Abstract Eight 2-phenylnaphthalenoids (2PNs) (3a-h) and twenty four 2-phenylbenzofuranoids (2PBFs) (4a - 4j, 5a-5j, 6a, 6f-6h) were successfully designed, synthesized and their antiproliferative and in vitro DNA topoisomerase inhibitory activities were evaluated. Nine compounds (four 2PNs and five 2PBFs) showed either TopoI or TopoIIα inhibitory activities. Six compounds (four 2PNs and two 2PBFs) exhibited potent cytotoxicity with IC50 values for 72 h exposure ranging from 0.3 to above 20 μM against MDA-MB-231, MDA-MB-435, HepG2 and PC3 cell lines. The two 2PBFs displayed comparable and even better antiproliferative as well as TopoIIα inhibitory activities than 2PNs. Interestingly, the active 2PBFs displayed different mechanisms of TopoIIα inhibition from that of 2PNs, suggesting that the chromophore scaffold replacement may result in a change of the binding site of inhibitors to TopoIIα. Furthermore, the mechanisms of antiproliferation on MDA-MB-231 cells indicate that compounds 5a and 5f are promising for further development of anticancer agents. The results of this study reveal that the evolutionary strategy of medicinal chemistry through scaffold hopping is a promising strategy for structure optimization of TopoIIα inhibitors.
