Dual Superlyophobic Materials for Under-Liquid Microfluid Manipulation, Immiscible Solvent Separation, and CO Blockage.

Oily water purification, immiscible solvent separation, sensitive microreaction, and CO blockage are of great interest because of their importance for the environment and demands of controllable microreactions. However, one specific material that can meet all the requirements has yet to be reported. Herein, we developed a simple environment-benign method to prepare specific dual superlyophobic materials to solve the problems mentioned earlier.

New Jatrophane-Type Diterpenoids from Euphorbia kansui as Potential MDR Reversal Agents.

A serial jatrophane-type diterpenoids, comprised with three undescribed compounds kanesulones C-E (1-3) and four known ones (4-7), were obtained from the roots of Euphorbia kansui. The structures of compounds 1-3 were elucidated by detailed interpretation of their spectroscopic data, especially 2D-NMR and HR-ESI-MS, the absolute configuration of 1 was revealed by single crystal X-ray diffraction. These isolates were assayed for their multidrug resistance reversing activities on human breast adenocarcinoma cell line MCF-7/ADR.
