COMPOSITION
Two fractions. Multiple regulatory systems.
Fast-moving heparin-like fraction
~80% of the complex
- Antithrombin III relationship — the endogenous serine-protease inhibitor pathway
- Activity involving coagulation proteases
- Heparan-sulfate-like character
- Endothelial-surface glycosaminoglycan relationship
- Possible contribution to the glycocalyx hypothesis
Dermatan sulfate
~20% of the complex
- Heparin cofactor II interaction
- Thrombin regulation through a second endogenous pathway
- Extracellular-matrix relevance
- Complementary role within the complex
Sulodexide’s scientific identity lies in the interaction of two glycosaminoglycan fractions rather than one isolated pharmacological action.
Why characterisation matters
“Sulodexide” names a complex biological mixture. Fraction proportions, molecular-weight distribution, charge density, sulphation pattern, chromatographic behaviour, potency, impurities, batch consistency and anticoagulant activity all define what the substance in a given vial or capsule actually is. For a research programme, identity testing is not bureaucracy — it is the difference between studying a defined architecture and studying an assumption.
Composition and characterisation is research pillar 7 of the Panacea programme; the analytical methods themselves are part of the research output Panacea expects to develop.
