To explore the chemical modifications, mechanisms of action, and therapeutic applications of non-anticoagulant heparins (NAHs).
Approach:
Chemical Modifications: NAHs are prepared through techniques such as periodate oxidation, N-desulfation, and glycol-splitting to retain therapeutic benefits while removing anticoagulant activity.
Biological Activities: NAHs exhibit anti-inflammatory, anticancer, antiviral, and vascular protective effects by interacting with proteins like heparanase, P-selectin, and HMGB1.
Therapeutic Applications: NAHs have potential applications in treating inflammatory disorders, cancer, sepsis, and viral infections, and can enhance drug delivery through systems like hydrogels and nanoparticles.
Key Findings:
NAHs retain many biological activities of heparin while exhibiting reduced or absent anticoagulant effects.
Chemical modifications allow NAHs to interact with key proteins involved in various diseases.
Promising results from preclinical and clinical studies suggest diverse therapeutic applications for NAHs.
Interpretation:
Limitations:
Recent clinical failures highlight translational barriers in NAH development.
The review does not provide specific clinical trial outcomes or detailed efficacy data.
Conclusion:
NAHs represent a class of drugs with potential applications across multiple therapeutic areas.
