Genetic code expansion for chemosensing and chemical actuation of biological functions
Bulletin of the Korean Chemical Society, EarlyView.Genetic code expansion (GCE) broadens the chemical repertoire for precise control of protein function in biological systems. This review highlights GCE‐based sensing and actuating systems that operate through selective interactions between noncanonical amino acids and chemical triggers.

European Journal of Organic Chemistry, EarlyView.Near‐infrared fluorescent pH indicators based on perylenediimide were constructed in a modular receptor–spacer–fluorophore–spacer–receptor format with heterocyclic amino moieties at the bay positions. Counterintuitively, the dibrominated intermediate with two heavy atoms is more emissive than the heterocyclic compounds.

A unique iridium(III) complex-based chemosensor for multi-signal detection and multi-channel imaging of hypochlorous acid in liver injury [PDF]
, 2017 Although hypochlorous acid (HOCl) has long been associated with a number of inflammatory diseases in mammalian bodies, the functions of HOCl in specific organs at abnormal conditions, such as liver injury, remain unclear due to its high reactivity and ...

Ketogenic diet for infantile epileptic spasms
Epilepsia Open, EarlyView.Abstract Approximately half of all cases of Infantile Epileptic Spasms Syndrome (IESS) do not respond to vigabatrin and hormonal therapies. There is no clear consensus as to the second‐line therapy for IESS. Ketogenic diet (KD) has emerged as an effective treatment for certain drug‐resistant epilepsies and in many cases of IESS.

Synthesis of a new azo Schiff base colorimetric chemosensor for detection of cyanide and acetate anions [PDF]
شیمی کاربردی روزIn this paper, a novel azo Schiff base chemosensor was synthesized via condensation reaction of 4-Aminoantipyrine with 1-(3-Formyl-4-hydroxyphenylazo)-3-nitrobenzene. The imine sensor was studied via spectroscopic methods IR, 1HNMR and UV-Vis.
