Summary: In this study, new examples of phenanthrolindiamides with asymmetric centers in amide substituents were synthesized and their structures were confirmed by spectral analysis and X-ray analysis. The synthesized ligands were found to form complexes with nitrates of rare-earth elements, and the stability constants of these complexes in acetonitrile solution were measured. Solvent extraction experiments showed that the presence of methyl groups in cyclic amide substituents significantly affected the distribution ratios and selectivity factors in the lanthanides(iii) and Am(iii) series.

Summary: The regioselective hydroxyphosphorylation of 1,3-enynes catalyzed by copper/di-tert-butyl peroxide is described in this study. The advantages of this radical reaction include excellent functional group tolerance, the use of a catalytic amount of copper and di- tert-butyl peroxide as a radical initiator, and mild reaction conditions. The desired products are obtained in moderate to excellent yields after purification.

Summary: In this study, two novel Cu(I) complexes were synthesized by liquid-assisted grinding (LAG) method followed by heating. The complexes were characterized using SC-XRD, FT-IR, and UV-Visible spectroscopy. Theoretical calculations showed that both complexes have higher third-order nonlinear optical (NLO) response compared to prototypical urea.

Summary: RcoM is a heme-containing transcription factor that can sense CO and is one of the regulators of CO metabolism in bacteria. The structure and DNA-binding properties of RcoM are not well characterized. In this study, it was demonstrated that RcoM-1 from Paraburkholderia xenovorans is a dimer and the heme-binding domain mediates dimerization. Through bioinformatics analysis, it was found that RcoM exists in three different genomic contexts, and a refined consensus DNA-binding sequence for RcoM was proposed. It was also discovered that PxRcoM-1 requires all three repeat sites to cooperatively bind DNA. These findings suggest that RcoM interacts with DNA in a unique manner.
