AI Article Synopsis

  • Staphylococcus aureus and Staphylococcus epidermidis are significant pathogens responsible for hospital infections and can attach to medical devices by forming biofilms.
  • PNAG is a polysaccharide found on both bacteria that can trigger antibody production, providing protection against these infections in animal models.
  • The study involves synthesizing various PNAG sugar fragments and bonding them to bovine serum albumin using reductive amination for potential vaccine development.

Article Abstract

Staphylococcus aureus and Staphylococcus epidermidis are prominent bacterial pathogens of nosocomial infections. Both microorganisms colonize medical devices by forming adherent biofilms. Poly-β-D-(1→6)-N-acetyl-glucosamine (PNAG) is a surface polysaccharide antigen which was found on both S. aureus and S. epidermidis. Animal studies have proved that PNAG can elicit antibodies which protect against staphylococcal infections. We have presented the synthesis of di-, tetra- and hexasaccharide fragments of PNAG with formyl-heptyl aglycone and their attachment to bovine serum albumin (BSA) by reductive amination.

Coacervation based on liquid-liquid phase separation (LLPS) has been widely used for the preparation of artificial protocells and to mimic the dynamic organization of membrane-free organelles. Most complex synthetic coacervates are formed through electrostatic interactions but cannot withstand high ionic strength conditions (>0.1 M).

Palladium catalysts form a cornerstone of modern chemistry with upmost scientific and industrial impact. Bulk palladium metal itself is chemically inert, and a sequence of chemical transformations has to be utilized to convert the metal into Pd pre-catalyst covered by ligands. However, the "cocktail" of catalysis concept discovered recently has shown that Pd systems can efficiently operate in catalysis without the necessity of a complicated and expensive pre-installed ligand environment.

Objective: In search of efficient anticancer agents, we aimed at the design and synthesis of a library of tetrasubstituted alkenes. These are structural analogues of tamoxifen, one of the widely used anticancer therapeutics.

Methods: Our small organic compound library was prepared via a chemical synthesis in the solution using the Larock three-component coupling reaction, which is known to tolerate diverse functional groups.
