AI Technical Summary

Technical Problem

Existing uric acid-lowering drugs have significant side effects and are unsafe for long-term use. Furthermore, a low-purine diet has limited effect on uric acid regulation and cannot effectively prevent or treat hyperuricemia and gout.

Method used

Using fucoidan (MF) from wakame spore leaves as the active ingredient, it increases uric acid excretion by inhibiting the renal uric acid transport proteins URAT1 and GLUT9, and helps to inhibit hepatic xanthine oxidase, thereby reducing uric acid levels, and can be prepared into pharmaceuticals, health foods and food products.

Benefits of technology

Fucoidan from wakame spore leaves is safe and non-toxic, significantly reduces serum uric acid levels, decreases the frequency and severity of gout attacks, and provides a safe and effective uric acid-lowering solution.
