A. Schematic representation of SST-0001 and chemical modification characterizing the heparin derivative. Given the polymeric nature of SST-0001 (average molecular weight, 20 kDa) a "statistical" representation of the structure is shown.
B. Schematic representation of M402 (average molecular weight, 6 kDa). As for SST-0001, a "statistical" representation of the structure is shown. R=SO3 or Ac.
