Smilagenin
目录号 : GC37652Smilagenin (SMI) 是一种脂溶性小分子甾体皂苷元,来自知母 Rhizoma anemarrhenae 和天竺葵 Radix asparagi,广泛用于治疗慢性神经退行性疾病的中药。Smilagenin (SMI) 通过增加毒蕈碱受体亚型 1 (M1)-受体的的密度来改善老年大鼠的记忆。Smilagenin (SMI) 通过刺激脑源性神经营养因子的基因表达减弱 Aβ(25-35) 诱导的神经变性,可能代表 AD 的新型治疗策略。

Smilagenin (SMI) is a lipid-soluble 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].
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]. Cell Viability Assay[3] Cell Line: SH-SY5Y cells
Smilagenin (intragastric administration; 10 or 26 mg/kg, once daily; 60 days) prevents the impairment of dopaminergic neurons in chronic MPTP/probenecid-induced mouse model[2]. Animal Model: MPTP/probenecid-induced mouse model[2]

工作液浓度: mg/ml;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL,
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL saline,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
