Prospects for the Application of Nephroprotectors of Plant Origin Based on Lespedeza bicolor

Abstract

Chronic kidney disease is a significant risk factor for the development of various non communicable diseases, including cardiovascular diseases. Every year there is a tendency to increase the number of patients with urinary system diseases. Chronic kidney disease is a global medical and social problem that leads to early disability of the working population. Today, scientists are focusing considerable attention on the search for new drugs with hypo azotheamine activity, as it is important to slow down the progress of chronic kidney disease. Herbal medicines are promising for the prevention and treatment of such pathologies. Plants with proven significant hypo-azotemic activity and safety include representatives of the genus Lespedeza, in particular, Lespedeza capitata and Lespedeza bicolor. The objective: to review the literature on the chemical composition and biological action of Lespedeza capitata, Lespedeza bicolor and the prospects for the use of a domestic medicinal product based on the herb Lespedeza bicolor as a hypoazotemic agent. Results. According to the literature, the chemical composition of Lespedeza capitata and Lespedeza bicolor differs slightly and is represented by flavonoids, procyanidins, hydroxycinnamic acids, etc. The therapeutic effect of these plants is associated primarily with the glycosides quercetin, luteolin (isorientin, vitexin) and kaempferol (robinin). It has been found that the complex of biologically active substances included in the preparation has nephro- and hepatoprotective, hypo-azotemic, antidiabetic, anti-inflammatory and diuretic effects and is promising in the treatment of many diseases of the urinary system. Conclusions. Literature sources indicate that the extracts from the shoots of Lespedeza capitata and from the herb Lespedeza bicolor are similar in chemical composition and pharmacological properties. Ethanol extracts based on Lespedeza capitata and Lespedeza bicolor have a long history of use and are characterised by proven hypo-azotemic, nephroprotective and anti-inflammatory effects. They are successfully used for the prevention and treatment of chronic renal failure, acute and chronic nephritis and extrarenal azotemia. The complex of biologically active substances contained in herbal remedies helps to increase renal filtration, reduce azotemia, increase diuresis, enhance sodium excretion and, to a lesser extent, potassium excretion.
