Abstract: Low molecular weight heparin (LMWH) suitable for equivalent use to USP enoxaparin sodium is prepared from a starting material isolated from engineered E. coli K5 capsular polysaccharide, e.g., E. coli K5 heparosan. The E. Coli CPS is treated with acids to remove 3-deoxy-D-manno oct-2-ulosonic acid (Kdo) residues, and further hydrolyzed via alkali treatment to form low molecular weight N-sulfo, N-acetyl heparosan (LMW-NSNAH) having molecular weight and N-acetylation comparable to enoxaparin. The LMW-NSNAH is converted to LMWH via a series of enzymatic modifications by C5-epimerase, 2-O-, 6-O-, and 3-O-sulfotransferases. Compositions including the LMWH are prepared without the use of porcine-derived heparin, and thus benefit from better source material availability, better control of manufacturing processes, reduced concerns about contamination, adulteration or animal virus, or impurities. Further, the LMWH product is demonstrated to be structurally and functionally comparable traditional pharmaceutical LMWHs.
