Usage And Synthesis

Description

Astilbin is a flavonoid that has been found in S. glabra and has diverse biological activities. It inhibits cisplatin-induced increases in apoptosis and accumulation of reactive oxygen species (ROS) in HEK293 cells when used at a concentration of 200 μM. Astilbin (50 mg/kg) increases renal glutathione (GSH) levels and superoxide dismutase (SOD) and catalase activity and reduces serum creatinine and blood urea nitrogen (BUN) levels, renal IL-1β, IL-6, and TNF-α levels, apoptosis in kidney tissue, and kidney injury in a mouse model of cisplatin-induced nephrotoxicity. It reduces loss of dopaminergic neurons in the substantia nigra and increases striatal GSH levels and SOD activity in a mouse model of MPTP-induced Parkinson''s disease when administered at a dose of 50 mg/kg per day. Astilbin also reduces descent time in a pole test and increases traction test score in a mouse model of Parkinson''s disease, indicating reduced motor deficits. It reduces cell viability of MDA-MB-231 and MCF-7 cells (IC₅₀s = 167.9 and 191.6 μM, respectively), as well as inhibits migration and increases apoptosis when used at concentrations of 50 and 200 μM. Astilbin (20 mg/kg every other day for 14 days) reduces tumor growth in an MCF-7 mouse xenograft model.

Chemical Properties

White crystalline powder, soluble in boiling water, almost insoluble in ether, from Poria cocos, Sarsaparilla, yellow wolfberry Engelhardtia roxburghiana Wall. red velvet goat's foot.

Uses

Astilbin displays anti-depressant activity involving monoaminergic neurotransmitters an the BDNF signal pathway. Anti-oxidant.

Definition

ChEBI: A flavanone glycoside that is (+)-taxifolin substituted by a alpha-L-rhamnosyl moiety at position 3 via a glycosidic linkage.

in vivo

To explore whether Astilbin improves CDDP-induced nephrotoxicity in vivo, an acute cisplatin nephrotoxic mouse model is established. Single injection of CDDP with 8 mg/kg dose results in notable weight loss compared with control group. However, the phenomenon is significantly alleviated by Astilbin at dose of 50 mg/kg. The mice fed Astilbin alone do not show any obvious alteration in body weight. Similarly, serum creatinine (SCr) and blood urea nitrogen (BUN) are higher in CDDP-treated mice than in control group. Treatment with Astilbin also decreases SCr and BUN levels. To examine the protective effect of Astilbin on CDDP-induced renal histopathological damage, the mouse kidney sections are stained with H&E. The mice in control group and Astilbin treated group have normal kidney morphology, while kidneys in CDDP group show severe damage with tubular degeneration, necrosis and cystic dilatation of the tubules with focal hemorrhages. Administration of Astilbin mitigated kidney injury, resulting in lower histopathological score compared to CDDP group. The apoptosis of renal cells is also detected using TUNEL staining to determine whether Astilbin treatment decreased renal cell apoptosis in CDDP-induced acute nephrotoxic mice^[1].
