Molecular Insights into Leech-Derived Bioactive Compounds: Biochemical Mechanisms and Therapeutic Potential
Review published in Int J Mol Sci (2026)
Abstract
The bioactive compounds that are produced by leeches combine traditional and modern treatment since the saliva of the animal contains proteins and peptides with anticoagulant, anti-inflammatory, antimicrobial, antioxidant, and regenerative properties. In this review, their biochemical profile, mechanisms and clinical uses are considered with a special focus on the fact that they are utilized to combine traditional practices with the modern developments in biomedical approaches. Proteomic and transcriptomic research has recently found more than 100 bioactive molecules, such as hirudin, calin, eglins, bdellins and destabilase, which are related to the blood-feeding process and therapeutic processes. These compounds control blood clotting, control inflammatory mediators, block microbes and enhance wound healing and the development of new blood vessels. In clinical practice, leech therapy is common in the reconstruction and microsurgical practice to reduce venous congestion and enhance graft success. They are also shown to be useful in wound healing, cardiovascular health, musculoskeletal conditions and regenerative medicine, as well as emerging drug delivery systems of recombinant proteins and nanocarriers. Some of the challenges involve biological variation, infection or bleeding risks and stringent regulations on purity and standardization. Biotechnology has improved through other developments such as recombinant protein production, high-throughput omics, and nanotechnology, which will help resolve these problems, making them safe and scalable for clinical use. Altogether, leech bioactives are the prime examples of the sophisticated pharmacology of nature, which have the potential of being used as therapeutic agents in the future. The recent approach and incorporation in personalized medicine and bioengineering models reflect the leech's capacity to address complicated illness and unmet healthcare requirements to reassert its significance in preventive medicine and recent biomedicine.

Resumen
Comprehensive molecular review of leech salivary bioactives including hirudin, calin, eglins, bdellins, and destabilase. Surveys recent proteomic and transcriptomic findings (>100 bioactive molecules), mechanisms of anticoagulant, anti-inflammatory, antimicrobial, antioxidant, and regenerative actions, plus clinical applications.
Por qué esto importa para la hirudoterapia
This review examined the biochemical profile, mechanisms, and therapeutic applications of leech-derived bioactive compounds, noting that proteomic and transcriptomic research has identified over 100 molecules—including hirudin, calin, eglins, bdellins, and destabilase—with anticoagulant, anti-inflammatory, antimicrobial, antioxidant, and regenerative properties. Clinical uses discussed include reducing venous congestion in reconstructive and microsurgical practice, wound healing, cardiovascular health, and emerging drug delivery systems using recombinant proteins and nanocarriers. This article is directly relevant to ASH's domain, as it comprehensively addresses the leech secretome and hirudotherapy applications. As a review, it synthesizes existing literature rather than presenting new experimental data; the abstract notes challenges including biological variation, infection and bleeding risks, and regulatory issues around purity and standardization.
