characteristics. This covalent functionalization sequence is extended towards a second noncovalent attachment of tailor‐made nonionic amphiphilic molecules to the pristine coated core–shell nanoparticles via solvophobic (i.e. either hydrophobic, lipophobic, or fluorophobic) interactions. Thereby, orthogonal tuning of the surface energies of nanoparticles vianoncovalentinteractions is accomplished. As
我们描述了一种通用的湿化学逐壳涂覆工艺,该工艺产生胶体二氧化钛(TiO 2)和氧化铁(Fe 3 O 4具有动态和可逆可调表面能的纳米粒子。通过使用长链烷基,三乙基乙二醇和全氟烷基膦酸可实现强大的共价表面官能化,从而产生具有疏水,亲水或超疏水/亲氟表面特性的高度稳定的核壳纳米粒子。该共价功能化序列扩展为通过非亲溶剂性(即疏水性,疏脂性或疏氟性)相互作用将定制的非离子两亲分子第二次非共价连接至原始包覆的核壳纳米粒子。由此,完成了通过非共价相互作用对纳米粒子的表面能进行正交调节。因此,
Synthesis and biological evaluation of<i>N</i>-acylated tyramine sulfamates containing C-F bonds as steroid sulfatase inhibitors
Steroidsulfatase (STS) is responsible for the hydrolysis of biologically inactive sulfated steroids into their active un-sulfated forms and promote the growth of various hormone-dependent cancers (e.g., breast cancer). Therefore, the STS enzyme is a promising therapeutic target for the treatment of steroid-sensitive cancers. Herein, we report the synthesis and biological evaluation of sulfamate analogs

2-diamidocyclohexane core and two perfluorinated ponytails, whose lengths vary from three to ten carbon atoms (CF3 to CF10). Investigation of the xerogels aims to provide in-depth information on the chain length effect. LMWGs with a higher degree of fluorination (CF7 to CF10) form superhydrophobic xerogel coatings with very low surface energies. Scanning electron microscopy images of the coatings show that the aggregates

A method of obtaining an enantioenriched organic compound comprising the steps of: 1) generating from a starting racemic, non-enantiopure or achiral compound a first mixture comprising at least one fluorous-tagged compound and at least one other non-fluorous tagged compound, at least one of these two compounds being enantioenriched relative to the starting compound; 2) contacting a first non-fluorous phase including the first mixture with a fluorous phase at a first phase interface, the fluorous-tagged compound distributing between the first non-fluorous phase and the fluorous phase; and 3) contacting the fluorous phase with a second non-fluorous phase at a second phase interface. The method further includes the step of having a third compound in the second non-fluorous phase that reacts with the fluorous-tagged compound to produce a second compound and the step of generating the first mixture by chemical or enzymatic kinetic resolution of a racemic or non-enantiopure compound.
