Direct Regioselective Esterification at O-2 of β-Cyclodextrin and Hydrolysis by Neighboring-group Participation

E-Journal of Chemistry, 2012
A simple and efficient strategy for direct regioselective esterification at O-2 of β-cyclodextrin was developed by using the combination of N,N'-carbonyldiimidazole and carbonate buffer in 1,4-dioxane, which does not require large amounts of polar ...

Transfersomes with core and surface‐loaded NF‐κB p65 siRNA for enhanced transdermal transfection and effective treatment of psoriasis

BMEMat, EarlyView.
TCPL, a transfersome with Tween 80 and PEI, enables efficient transdermal siNF‐κB delivery, resolving PEI's toxicity issue. It promotes lysosomal escape and effective transfection, silences NF‐κB, modulates immunity, and inhibits angiogenesis, alleviating psoriasis. With good biocompatibility, TCPL holds strong clinical translation potential. Schematic

Isodesmic Supramolecular Assembly of Phenylethynylene Bis‐Urea Macrocycles

Chemistry – A European Journal, EarlyView.
A soluble phenylethynylene bis‐urea macrocycle assembles in polar media via an isodesmic hydrogen bonded mechanism. Spectroscopic and morphological studies reveal nanoscale aggregates with short chain length, while guest additives modulate enthalpy and polymerization, demonstrating tunable supramolecular assembly.
