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.
Smilagenin (SMI) improves memory of aged rats by increasing the muscarinic receptor subtype 1 (M1)-receptor density.
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.
体外研究
Smilagenin (10 μM; 24 hours) increases SH-SY5Y cell survival compared with Aβ(25-35) intoxicated cells.
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.
