The First Kleinman-type Second-Harmonic Generation Circular Dichroism On/Off Switchable Ferroelectrics.

Chiral ferroelectrics have recently received considerable interest due to their unique chiroptical properties. They can adopt Kleinman symmetry second-harmonic generation (SHG)-active chiral-polar point groups in the ferroelectric phase while Kleinman symmetry SHG-inactive chiral-nonpolar point groups in the paraelectric phase, providing a great opportunity to realize on/off switching of SHG circular dichroism (SHG-CD) response. However, the SHG-CD effect was rarely explored in chiral ferroelectrics, and the on/off switchable SHG-CD has never been reported.

The combination of polyphenols and protein can improve the functional characteristics of protein. How to effectively promote the binding of polyphenols to protein is still a difficult topic. In this study, hydrodynamic cavitation (HC) was used to induce the fabrication of complexes between soy protein isolate (SPI) and different polyphenols (tannic acid (TA), chlorogenic acid (CGA), ferulic acid (FA), caffeic acid (CA), and gallic acid (GA)).

Their structures were elucidated primarily by NMR experiments. The absolute configurations of 2-6 were assigned by electronic circular dichroism calculations, respectively.

The design of metalloproteins allows us to better understand metal complexation in proteins and the resulting function. In this study, we incorporated a Cu-binding site into a natural protein domain, the 58 amino acid c-Crk-SH3, to create a miniaturized superoxide dismutase model, termed SO1. The resulting low complexity metalloprotein was characterized for structure and function by circular dichroism and UV spectroscopy as well as EPR spectroscopy and X-ray crystallography.

Non-canonical DNA structures formed by aberrantly expanded repeat DNA are implicated in promoting repeat instability and the onset of repeat expansion diseases. Small molecules that target these disease-causing repeat DNAs hold promise as therapeutic agents for such diseases. Specifically, 1,3-di(quinolin-2-yl)guanidine (DQG) has been identified to bind to the disease-causing GGCCCC (G2C4) repeat DNA associated with amyotrophic lateral sclerosis and frontotemporal dementia (ALS/FTD).
