Methodology for Screening Effective Substances of Chinese Herbal Medicine for Reducing Serum Uric Acid Level
Gout is caused by the nucleation and growth of monosodium rate crystals in tissues and around joints
which is followed by long-standing hyperuricemia and serum urate of above the saturation threshold. It could cause a series of complications
such as cardiovascular
hypertension
and renal complications. Over the past two decades
the incidences of hyperuricemia and gout have been increasing due to the continuous improvement of living standards and the changes in dietary structure. The prime and most important therapy for hyperuricemia and gout is to reduce serum uric acid levels
but the western medicine for reducing uric acid in clinical application has serious toxic and side effects. With the rapid development of modern science and technology
the application and development of different screening methods for effective ingredients with a low toxicity and side effects from Chinese herbal medicines for reducing serum uric acid levels has attracted much attention in the research and development of drugs for the prevention and treatment of hyperuricemia and gout. In this study
the screening methods for extracts
fractions
active monomer components and other effective substances were reviewed and analyzed. According to the findings
the screening methods had a considerable progress both
in vivo
and
in vitro
. The results showed that the in vivo methods were mainly applied for studying the urate lowing effect and mechanisms of herbal extracts
while the studies for xanthine oxidase(XOD) inhibitors mainly depended on the
in vitro
methods. Molecular docking homology modeling and liquid chromatography-mass spectrometry have become a new trend for screening effective substances with XOD inhibitory activities and uric acid excretion activities
while cell model will open up a new way for screening effective substances for uric acid excretion. The review provides certain reference for effective components screening of hyperuricemia and gout.
