生物活性

Smilagenin (SMI) is a small-molecule steroidal sapogenin from Rhizoma anemarrhenae and Radix asparagi widely used in traditional Chinese medicine for treating chronic neurodegeneration diseases[1]. Smilagenin (SMI) improves memory of aged rats by increasing the muscarinic receptor subtype 1 (M1)-receptor density[2]. Smilagenin (SMI) attenuates Aβ(25-35)-induced neurodegenerationvia stimulating the gene expression of brain-derived neurotrophic factor, may represents a novel therapeutic strategy for AD[3].

体外研究
(In Vitro)

Smilagenin (10 μM; 24 hours) increases SH-SY5Y cell survival compared with Aβ(25-35) intoxicated cells[3].
Smilagenin (10 μM; 24 hours) increases neurotrophic factor (GDNF) and neurotrophic factor (BDNF) mRNA level by promoting CREB phosphorylation in 1-methyl-4-phenylpyridimium (MPP+) treated SH-SY5Y cells[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Viability Assay[3]

Cell Line: SH-SY5Y cells
Concentration: 10 μM
Incubation Time: 24 hours
