, p. 7289 - 7291 (2014)
4-(2,2,2-Trifluoroethoxy)nitrobenzene was used as raw material to create a reaction for 1 h at 70°C by using ethanol and palladium carbon as solvent and catalyst, respectively, to obtain the desired product 4-(2,2,2-trifluoroethoxy)aniline with 97% yield and 99.9% purity. NMR, IR, MS, GC and other analysis and detection methods were used to conduct qualitative and quantitative analyses of the desired product. This paper discussed the process conditions of hydrogenation and reduction reaction and mainly investigated the impact of dosage and recycling of catalyst.

We report a 19F MRI probe for the specific detection and imaging of -OCl. Our designed probe, having p-aminophenyl alkyl scaffold, reacted expeditiously with -OCl to produce a trifluoroethanol. Concomitant with the reaction, the 19F chemical shift changed by 2.6 ppm, allowing the visualization of -OCldependent probe-to-product conversion using 19F MRI.

Small molecule mitochondrial uncouplers have recently garnered great interest for their potential in treating nonalcoholic steatohepatitis (NASH). In this study, we report the structure-activity relationship profiling of a 6-amino[1,2,5]oxadiazolo[3,4-b]pyrazin-5-ol core, which utilizes the hydroxy moiety as the proton transporter across the mitochondrial inner membrane. We demonstrate that a wide array of substituents is tolerated with this novel scaffold that increased cellular metabolic rates in vitro using changes in oxygen consumption rate as a readout. In particular, compound SHS4121705 (12i) displayed an EC50 of 4.3 μM in L6 myoblast cells and excellent oral bioavailability and liver exposure in mice. In the STAM mouse model of NASH, administration of 12i at 25 mg kg-1 day-1 lowered liver triglyceride levels and improved liver markers such as alanine aminotransferase, NAFLD activity score, and fibrosis. Importantly, no changes in body temperature or food intake were observed. As potential treatment of NASH, mitochondrial uncouplers show promise for future development.
Properties of liquid crystals and Cu2+ recognition based on Schiff bases

, p. 11 - 19 (2016/02/19)
Two series of new Schiff base compounds were synthesized. For Schiff base compounds with a pyridine nitrogen atom in 4-position (7a-e), their supramolecular hydrogen bonding complexes show good liquid crystal properties. However, no liquid crystal property is observed for 8a-e. Results of theoretical calculations demonstrate that it is the intermolecular hydrogen bond of Schiff base compounds (8a-e) that prevents the formation of supramolecular hydrogen bonding. The Schiff base compounds, with terminal alkoxy chains, can recognize Cu2+ selectively with a color change. Nevertheless, others cannot recognize Cu2+.
Fuorinated hydrogen bonding liquid crystals based on Schiff base
Liu, Zhilian,Zhang, Jian,Li, Tengfei,Yu, Zhenning,Zhang, Shuxiang
, p. 36 - 39 (2013/05/08)
Two new Schiff base compounds, tailed by the fluoroalkoxy, were synthesized in a three-step process. Those supramolecular structures constructed by hydrogen bonding show good liquid crystal properties with higher clear points and wider mesomorphic phase ranges than other analogs containing a terminal alkoxy chain. Investigation of the optical textures by polarizing microscopy reveals that terminal fiuorinated substituents convert the nematic phase of supramolecular hydrogen-bonding complexes with terminal alkoxy chains into the smectic A phase of those with terminal fluoroalkoxy chains.
