From Nature to Pharmacy: A Review of Tectoridin for Modern Therapeutics

Background: Tectoridin is a prominent isoflavone glycoside found in herbs such as Belamcanda chinensis (L.) DC and Iris tectorum Maxim. It has drawn increasing research interest due to its promising pharmacological activities. However, no critical review to date has determined whether its broad pharmacological activity stems from binding to specific targets or from the non-specific, broad-spectrum activity commonly associated with flavonoids. This paper provides a comprehensive review of tectoridin, covering its plant sources, pharmacological effects, pharmacokinetics, and toxicity, alongside an in-depth analysis of the mechanisms underlying its pharmacological effects and strategic recommendations for advancing its clinical translation. Methods: A systematic literature search was conducted in PubMed, Web of Science, Google Scholar, SciFinder, and CNKI for publications from 1968 to 2025 using keywords including tectoridin, tectorigenin 7-O-glucoside, traditional uses, ethnopharmacology, pharmacology, bioactive compounds, biological activity, pharmacokinetics and toxicity. Results: Tectoridin exhibits a broad spectrum of pharmacological activities, including anticancer, anti-inflammatory, hepatoprotective, antidiabetic, antioxidant, cardiovascular, and estrogenic effects. Pharmacokinetic studies have shown rapid tissue distribution and slow elimination; the aglycone metabolite tectorigenin often displays enhanced bioactivity, and chemical modifications may further improve efficacy. Toxicity data suggest relative safety in medicinal food contexts, but comprehensive in vivo studies remain limited. Tectoridin shows promise for treating cancer and inflammatory diseases; however, further research is needed to elucidate its molecular mechanisms, clarify toxicity, and optimize bioactivity. Conclusions: This review bridges natural products and modern therapeutics by focusing on tectoridin, highlighting its therapeutic potential, addressing challenges, and offering new perspectives for treating various diseases.
