[formula: see text] A new molecular system, 2,11-dithio[4,4]metametaquinocyclophane containing a quinone moiety, was designed and synthesized. As the quinone moiety can readily be converted into an aromatic pi-system (hydroquinone) upon reduction, th

[structure: see text] A positively charged tripodal receptor with nitro groups in the imidazolium rings was designed, synthesized, and characterized for its anion binding strength. The receptor shows strong affinity and high selectivity for Cl- throu

In the equilibrium unfolding process of Δ5-3-ketosteroid isomerase from Pseudomonas testosteroni by urea, it was observed that the enzyme stability increases by 2.5 kcal/mol in the presence of 5% trifluoroethanol (TFE). To elucidate the increased en

Equilibrium and kinetic analyses have been carried out to elucidate the folding mechanism of homodimeric ketosteroid isomerase (KSI) from Comamonas testosteroni. The folding of KSI was reversible since the activity as well as the fluorescence and CD

Four new C4v tetraoxatetrathiahemicarceplexes were synthesized and characterized. Their carceroisomers and half-twistomers were simultaneously observed by 1H NMR spectra at low temperature. The largest isomerization energy barrier of carceroisomers w

We have studied [n,n]metaparacyclophanes-model compounds exhibiting edge-to-face and displaced stacked aromatic-aromatic interactions-using semiempirical calculations for n = 2-5 and ab initio calculations for n = 2-4. For n = 2 and 3, the strain ene

On the basis of recently synthesized calix[4]hydroquinone (CHQ) nanotubes which were self-assembled with infinitely long one-dimensional (1-D) short hydrogen bonds (SHB), we have investigated the nature of 1-D SHB using first-principles calculations
