methods for treating triple-negative breast cancer (TNBC), which is known for poor prognosis and high rate of mortality. Two types of novel dual-targeting TNBC liposomes (Fru-RGD-Lip and Fru+RGD-Lip) that activelyrecognize both fructose transporter GLUT5 and integrin αvβ3 were designed and prepared in this work. Firstly, a Y-shaped Fru-RGD-chol ligand, where a fructose and peptide Arg-Gly-Asp (RGD) were

Provided herein are halogenated cholesterol analogues, including methods of making and using the same. Also provided are methods of making radiolabeled cholesterol analogues including admixing an epoxide with a fluorine-18 source under conditions to form a radiofluorinated cholesterol analogue.
A composite containing a liposome and a lipophilic ruthenium complex was synthesized to regulate an O2 evolution reaction using cerium(IV) ammonium nitrate as an oxidizing reagent. We found that the surrounding environment of the reaction centre is an important factor for controlling the O2 evolution catalytic reaction. We successfully regulated the reaction activity using the linker length of the

performing aqueousreactions for very sparingly soluble high-melting-point (VSSHMP) organic substrates has been developed, which entails mechanically stirring a mixture of the substrate, the corresponding reagent(s), water, catalytic Aliquat 336 and sand. When the melting points of the substrates which include steroids, ketones, aldehydes, aromatics and alkaloids are around 200 °C, the reactions can be
对于难溶性高熔点(VSSHMP)有机底物进行水反应的问题,已经开发出一种实用的解决方案,该方法需要机械搅拌底物,相应的试剂,水,催化性Aliquat 336的混合物和沙子。当包括类固醇,酮,醛,芳族化合物和生物碱的底物的熔点为约200℃时,反应可以在20℃下进行。底物溶解度可以低至1×10 -10 mol L -1。

A rapid oxidation of primary and secondary alcohols using catalytic amounts of TEMPO and Yb(OTf)3 in combination with a stoichiometric amount of iodosylbenzene (PhIO) is described. This procedure operates at room temperature or above to afford carbonyl compounds in excellent yields without over-oxidation to carboxylic acids. Oxidation of primary alcohols in the presence of secondary alcohols proceeded with good selectivity.
