Expanding the horizons of bicyclol in multiple diseases: Mechanisms, therapeutic implications and challenges.

Bicyclol, a drug stemmed from the traditional Chinese medicine Schisandra chinensis, has been widely utilized in clinical practice due to its efficacy and safety to manage hepatopathy. Its diverse biological properties-including antiviral, anti-inflammatory, antifibrotic, immunomodulatory, antioxidative, antisteatotic, and antitumor effects-underscore its significant medicinal effects in versatile hepatic disorders, incorporating viral hepatitis, non-alcoholic fatty liver disease, hepatocellular carcinoma, acute hepatic failure, hepatic fibrosis as well as drug-induced liver injury. Furthermore, ongoing researches into the molecular mechanisms, biological activities and mode of actions concerning bicyclol have uncovered its potential therapeutic implications in other multiple diseases/conditions. Studies have indicated promising efficacy pertaining to bicyclol to treat idiopathic pulmonary fibrosis, acute lung injury, cerebral ischemia/reperfusion injury, renal dysfunction, renal cell carcinoma, and cardiovascular diseases. Accordingly, this narrative review article summarizes the current understanding of diverse biological activities and underpinning mechanisms of bicyclol across a range of diseases, as well as its pharmacokinetics, toxicity profile and shed light on future perspectives.
