Low molecular weight heparinsLMWHsare partially depolymerized natural products of heparinwhich are isolated from porcine intestineA worldwide distribution of contaminated heparin inwas associated withdeaths in the USThis crisis revealed the vulnerability of the LMWH supply chainLMWHs are complex mixtureshaving average molecular masses ofDaltonscorresponding tosaccharide unitsThe efficient preparation of a synthetic LMWH could improve the safetyavailability and efficacyHoweverthe production of homogeneous LMWHs has not been possible due to difficulties in the chemical synthesisGlycan Therapeutics proposes to assess an innovative chemoenzymatic approach that would provide an unprecedented efficiency in the preparation of heparinOur product will be animalfreestructurally homogenoussafe for renal impaired patientsand have the ability of its anticoagulant activity to be neutralized by protamineIn the phase I STTR studieswe have identitifed a heparin dodecasaccharidemeras a candidate to substitute animal sourced LMWHWe also demonstrated the ability to synthesize thismer at the scale ofg in four batchesIn the presently proposed Phase II SBIR studieswe will assess the feasibility of a larger scale synthesisgramsto conduct IND enabling studiesAimwill develop a process to prepareg of themer via a series of efforts for improving enzyme productionreaction efficacy and simplifying purificationsAimwill examine the immunogenicity of themer in a murine modelWe will also conductday toxicity studies in rat and dog as well as related IND enabling studiesThe completion of this project will modernize this century old drug with improved safety and anticoagulant properties Project Narrative Heparin and low molecular weight heparinsLMWHsare mixtures of highly sulfated polysaccharides isolated from animal tissuesIn this projectGlycan Therapeutics plans to use an innovative chemoenzymatic technology to synthesize heparinsThe project is designed to improve the safety of heparin drugsand to reduce the cost of heparin synthesis
