Researchers at Brandeis University Release New Data on Chemotherapy (Dephosphorylation of D-peptide derivatives to form biofunctional, supramolecular nanofibers/hydrogels and their potential applications for intracellular imaging and ...)

By a News Reporter-Staff News Editor at Biotech Week -- Current study results on Drugs and Therapies have been published. According to news reporting from Waltham, Massachusetts, by NewsRx journalists, research stated, "D-Peptides, as the enantiomers of the naturally occurring L-peptides, usually resist endogenous proteases and are presumably insensitive to most enzymes. But, it is unclear whether or how a phosphatase catalyzes the dephosphorylation from D-peptides."

The news correspondents obtained a quote from the research from Brandeis University, "In this work, we examine the formation of the nanofibers of D-peptides via enzymatic dephosphorylation. By comparing the enzymatic hydrogelation of L-peptide and D-peptide based hydrogelators, we find that the chirality of the precursors of the hydrogelators affects little on the enzymatic hydrogelation resulted from the removal of the phosphate group from a tyrosine phosphate residue. The attachment of a therapeutic agent (e.g., taxol) or a fluorophore (e.g., 4-nitro-2,1,3-benzoxadiazole) to the D-peptide based hydrogelators affords a new type of biostable or biocompatible hydrogelators, which may find applications in intratumoral chemotherapy or intracellular imaging, respectively."

According to the news reporters, the research concluded: "This work, as the first comprehensive and systematic study of the unexpected enzymatic dephosphorylation of D-peptides, illustrates a useful approach to generate supramolecular hydrogels that have both biostability and other desired functions."
