Reports Outline Supramolecular Research Findings from Tokyo Medical and Dental University

June 24, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- Investigators publish new report on Supramolecular Research. According to news reporting from Tokyo, Japan, by NewsRx journalists, research stated, "The effects of the supramolecular polyrotaxane (PRX) structure on cellular internalization are investigated by flow cytometry and confocal laser scanning microscopy. AF-545-labeled aminated PRXs (APRXs) containing different numbers of threaded -cyclodextrins (CDs) and amino groups are synthesized; their cellular uptakes are analyzed using HeLa cells in serum."

The news correspondents obtained a quote from the research from Tokyo Medical and Dental University, "The APRX threaded CD number is discovered to be a more critical factor for enhancing cellular internalization than the APRX amine content. Additionally, APRXs are demonstrated to be more easily internalized than conventional linear cationic macromolecules."

According to the news reporters, the research concluded: "Because increased numbers of threaded CDs are related to increased PRX rigidity, the PRX rigid frame resulting from CD molecules threaded on a poly(ethylene glycol) (PEG) chain is suitable for intracellular tools in therapy and diagnosis."
