A streamlined protocol for the detection of mRNA–sRNA interactions using AMT-crosslinking in vitro

BioTechniques, 2019
Until recently, RNA–RNA interactions were mainly identified by crosslinking RNAs with interacting proteins, RNA proximity ligation and deep sequencing. Recently, AMT-based direct RNA crosslinking was established.

Template-Directed One-Step Synthesis of Cyclic Trimers by ADMET

Journal of the American Chemical Society, 2006
A trifurcated template, containing three secondary dialkylammonium ion recognition sites for encirclement by a dibenzo [24]crown-8-containing acyclic diene, is used to promote acyclic diene metatheses (ADMET) catalyzed by ruthenium-alkylidene complexes, affording a cyclic trimer in 55% yield.

Iron-Binding and Anti-Fenton Properties of Novel Amino Acid-Derived Cyclic Imide Dioximes

Antioxidants, 2019
We present a novel route for the preparation of amino acid-derived cyclic imide dioxime derivatives. Readily accessible amino acids were conveniently converted to their corresponding cyclic imide dioximes in simple synthetic steps.
