Designer heparinoids by Heparinex, fine-tuned size and structural control

Innovative Biopharmaceutical Compound Synthesis

Heparinex, L.L.C. is a biopharmaceutical company focused on the novel recombinant synthesis of compounds for markets including anticoagulation, inflammation, and cancer treatment areas. Leading carbohydrate chemist and glycobiologist Dr. Paul DeAngelis, originally discovered and patented Heparinex’s core technology platforms of proprietary carbohydrate production.

Heparinex’s Core Platforms Employ

  • Bacterial production techniques
  • In vitro defined, enzyme-catalyzed polymer syntheses to provide uniquely controlled non-animal sources of heparinoid compounds for biotherapeutic, tissue engineering, and medical device applications


Heparinex was founded upon the discovery of two novel methodologies to produce synthetic heparinoid compounds in a highly controlled manner. Heparin is used as an anticoagulant and antithrombotic agent in a wide variety of medical conditions. Traditional production techniques involve procuring and purifying heparin from sources such as porcine intestine and bovine lung. While the current methods are adequate, they limit the potential applications of heparin due to the inherent variability in the molecular size and weight of the heparin chains. The Heparinex solution circumvents these issues by providing techniques to produce uniform monodisperse heparin chains.

Carbohydrate Expertise

Dr. Paul L. DeAngelis serves as the Chief Scientist of Heparinex. Dr. DeAngelis is a recognized leader in the glycobiology field and has been directly involved in commercializing technologies associated with heparin, chondroitin, and hyaluronic acid developed in his laboratories. As an undergraduate at Harvard (B.A. 1984), Dr. DeAngelis investigated the carbohydrate structures of polysaccharides from fungal pathogens that their plant hosts detected as “foreign” by creating and testing a series of synthetic structural mimics. As a graduate student at the University of California, Irvine (Ph.D. 1990), he elucidated unique details surrounding fertilization, such as defining the critical elements of egg surface polysaccharides and the essential residues of a sperm adhesive protein.

As a postdoctoral researcher (1990-93) in the laboratory of Dr. Paul Weigel at the University of Texas Medical Branch, Galveston, Dr. DeAngelis identified the first hyaluronan synthase to be described from the human bacterial pathogen Group A Streptococcus. Currently, as a Professor at the University of Oklahoma Health Sciences Center in Oklahoma City, he directs a laboratory exploring various aspects of prokaryotic and eukaryotic polysaccharide biosynthesis. Discoveries from 1997 to 2003 include the identification of two more unique hyaluronan synthases and the first chondroitin and heparin synthase.
