Description
Salicin is an alcoholic β-glucoside. Salicin is produced in (and named after) willow (Salix) bark and acts as an anti-inflammatory agent in the human body. Salicin is also commonly found in the bark of Populus species, and the leaves of willows and poplars. It is also found in castoreum, which was used as an analgesic, anti-inflammatory, and antipyretic. Salicin is closely related in chemical make-up to aspirin and has a very similar action in the human body. When consumed by humans, Salicin is metabolized into salicylic acid.
Willow bark contains an ingredient called salicin, which your body makes into another chemical substance called salicylic acid. Similar to acetylsalicylic, salicylic acid reduces the production of certain prostaglandins (hormone-like substances that control your immune system and fight joint inflammation) in your nerves, and this eases pain and discomfort. Willow bark showed anti-inflammatory activity in several laboratory-based studies.
Salicin has been studied as a potent antiinflammatory agent. Angiogenesis is an essential process for tumor progression, and negative regulation of angiogenesis provides a good strategy for antitumor therapy. However, the potential medicinal value of salicin on antitumorigenic and antiangiogenic effects remain unexplored. In this study, we examined the antitumorigenic and antiangiogenic activity of salicin and its underlying mechanism of action. Salicin suppressed the angiogenic activity of endothelial cells, such as migration, tube formation, and sprouting from an aorta. Moreover, salicin reduced reactive oxygen species production and activation of the extracellular signal‐regulated kinase pathway. The expression of vascular endothelial growth factor was also decreased by salicin in endothelial cells. When the salicin was administered to mice, salicin inhibited tumor growth and angiogenesis in a mouse tumor model. Taken together, salicin targets the signaling pathways mediated by reactive oxygen species and extracellular signal‐regulated kinase, providing new perspectives into a potent therapeutic agent for hypervascularized tumors. — John Wiley & Sons
