Design of a hydrophilic mercaptosuccinic acid-functionalized β-cyclodextrin polymer host-guest interaction: toward highly efficient glycopeptide enrichment.

A hydrophilic interaction chromatography (HILIC) strategy is considered as an efficient strategy for efficient glycopeptide enrichment. Here, a novel hydrophilic material (denoted as magCDP@Ada-MSA) was constructed through host-guest interaction between crosslinked β-cyclodextrin (β-CD) polymers and mercaptosuccinic acid (MSA) derived adamantane. On the one hand, crosslinked β-CD polymers have great hydrophilicity due to their abundant hydrophilic hydroxyl groups.

Supramolecular adsorbents in extraction and separation techniques - A review.

Sample preparation procedure before the detection step is of great importance for successful realization of an analytical method. The extraction and preconcentration efficiency, sample throughput, and application potential of a sample preparation approach are greatly dependent on adsorbents. This review (with 172 references) reveals a critical view on the latest achievements of supramolecular materials in the field of adsorption.

Discovery of Pimprinine Alkaloids as Novel Agents against a Plant Virus.

Plant viral diseases cause tremendous decreases in crop yield and quality. Natural products have always been a valuable source for lead discovery in medicinal and agricultural chemistry. A series of pimprinine alkaloids and their derivatives were prepared and identified by nuclear magnetic resonance (NMR) spectroscopy and high-resolution mass spectrometry (HR-MS).
