Novel Protein-Polymer Nanoassemblies for the Intracellular Delivery and Stimuli-responsive Traceless Release of Proteins

LEAD INVENTOR:
S. Thai Thayumanavan, Ph.D.
 
PRODUCT OPPORTUNITIES

  • Novel protein-polymer conjugates as prodrugs
  • Therapeutic protein-polymer conjugation kits
 
COMPETITIVE ADVANTAGES

  • Reversible and ultrafast click reaction between surface modified protein and synthetic polymer, enabling efficient protein encapsulation and triggered intracellular release
  • Versatile linker chemistry allowing for traceless protein release in its native form in response to different types of intracellular stimuli, such as a change in pH, reducing conditions or concentration of reactive oxygen species
  • Applicable to encapsulation and delivery of proteins of different sizes and isoelectric points
 
TECHNOLOGY DESCRIPTION
This invention provides a new intracellular protein delivery strategy that involves introducing ultrafast click reaction moieties into a therapeutic protein and a synthetic polymer to allow for the formation of protein-polymer nanoassemblies that are capable of releasing encapsulated protein in its native form in response to an intracellular trigger.
