Timosaponin BII is an antioxidant and an anti-inflammatory agent.
Timosaponin BII is a steroidal glycoside separated from Zhi Mu, is found to have the inhibitory activity against the proliferation of HL-60 (leukemic), Hela (cervix), HepG2 and Bel-7402 (liver), HT-29 (colon), and MDA-MB-468 (breast) human carcinoma cell lines with an IC50 value of 15.5 μg/mL in the HL-60 cells[1].
Rat retinas in model group and vehicle control group manifest an apparent up-regulation of BACE1 expression. Meanwhile, the level of malonaldehyde (MDA), Aβ1-40 and β-CTF are increased. However, when comparing with the vehicle control group, the retinas in Timosaponin-BII treated group showed significantly less BACE1 and accumulated less Aβ1-40 or β-CTF. It also showed significantly decreased level of MDA and prolonged partial thromboplastin time[2].

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。
