Summary: A series of novel non-ionic, sugar-based surfactants were synthesized to facilitate the formation of disulfides and thioamides in water under mild conditions. The formation of spherical micelles using AGA8 aqueous solution provided a confined reaction environment for thiol substrates and elemental sulfur (S-8). Both disulfides and thioamides were obtained in moderate to excellent yields with a high tolerance towards various functional groups using this environmentally friendly method. The disulfides were identified as intermediates for the synthesis of thioamides, and quantum chemical calculations suggested that an S-2 cluster was the most likely active species for the desired product formation.

Summary: Hydrogen is an ideal alternative to fossil fuels due to its sustainability and environmental friendliness. Dual-functional photocatalysis combines the production of hydrogen with the oxidation of organic molecules to utilize both photogenerated species simultaneously. In this study, metal-organic frameworks (MOFs) were investigated for their electron/hole dynamics and photophysical properties, and Pt/UiO-66-pz was found to be the most efficient dual-functional photocatalyst.

Summary: Coupled catalysis using a riboflavin-derived organocatalyst and molecular iodine facilitated the aerobic oxidation of thiols to disulfides under metal-free mild conditions. The activation of molecular oxygen at room temperature through electron transfer between the iodine catalyst and biomimetic flavin catalyst enabled a green oxidative synthesis of disulfides from thiols.

Summary: A metal-free and N-bromosuccinimide (NBS)-mediated direct thiol-disulfide exchange reaction at room temperature has been developed, which allows for the preparation of various unsymmetrical disulfides with good to excellent yields. The efficient late-stage modification of amino acids and drugs demonstrates the practicality of this strategy. Furthermore, the ease of operation, broad substrate scope, and good functional group tolerance make this reaction an essential complementary route to access unsymmetrical disulfides.

Summary: Two approaches to synthesis of unsymmetrical disulfides, namely electrochemical method and microwave irradiation, were discussed. The oxidative coupling of sulfur-centered radicals and a redox-mediator promoted thiol-disulfide exchange were found to be the main mechanisms of the electrochemical method. Microwave-assisted synthesis showed variable yields depending on irradiation parameters.

Summary: For the first time, dehydroabietane-derived alcohols with an OH group at the C-7 position were used to synthesize thioacetates via direct substitution catalyzed by ZnCl2. It was observed that the obtained thioacetates can be converted into disulfides when treated with MeONa in the presence of oxygen, without formation of thiols. Additionally, a new method for the conversion of diols with hydroxyl groups at C-7 and C-18 positions into cyclic dimers was discovered.

Summary: In this study, the impact of biocompatible synthetic polymers on the structure and dynamics of L-asparaginase was investigated using molecular dynamics simulations. The results demonstrate that the protein encapsulated in PLGA is more stable than in MPEG, primarily due to electrostatic interactions between the enzyme and PLGA. Hydrophobic and vdW interactions are the driving force for the protein-MPEG interaction. The study also highlights the critical roles of the protein's basic residues in the encapsulation mechanism.
