Glycyrrhizic acid (Synonyms: 甘草酸; Glycyrrhizin)

Glycyrrhizic acid 是甘草里面的活性成分三萜皂苷，為 HMGB1 的拮抗劑，有用于zhong瘤、糖尿病等研究的潛力。

生物活性

Glycyrrhizic acid is a triterpenoid saponinl, acting as a direct HMGB1 antagonist, with anti-tumor, anti-diabetic activities.

體外研究(In Vitro)

Glycyrrhizic acid shows a series of anti-cancer-related pharmacological activities, such as broad-spectrum anti-cancer ability, resistance to the tissue toxicity caused by chemotherapy and radiation, drug absorption enhancing effects and anti-multidrug resistance (MDR) mechanisms, as a carrier material in drug delivery systems^[1].
In intestinal NCI-H716 cells that secretes GLP-1, Glycyrrhizic acid promotes GLP-1 secretion with a marked elevation of calcium levels. Glycyrrhizic acid can enhance GLP-1 secretion through TGR5 activation^[2].
Glycyrrhizic acid can form a stable transparent low-molecular-weight hydrogels (LMWHs) at 37°C in physiological phosphate buffered saline (PBS) with nanoclusters as the microstructures^[4].

體內(nèi)研究(In Vivo)

n type 1-like diabetic rats induced by streptozotocin (STZ-treated rats), Glycyrrhizic acid increases the level of plasma GLP-1, which is blocked by triamterene at a dose sufficient to inhibit Takeda G-protein-coupled receptor 5 (TGR5)^[1]. Glycyrrhizic acid (Glycyrrhizic acid; 50 mg/kg, i.p.) significantly decreases the levels of TgAb, HMGB1, TNF-α, IL-6, IL-1β in mice^[3].
