Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC50/Ki
telomerase [1]
In vitro
Cycloastragenol stimulates telomerase activity and cell proliferation in human neonatal keratinocytes. It induces telomerase activity and cAMP response element binding (CREB) activation in PC12 cells and primary neurons. This compound treatment not only induces the expression of bcl2, a CREB-regulated gene, but also the expression of telomerase reverse transcriptase in primary cortical neurons[1]. It rapidly passes through the Caco-2 cell monolayer by passive diffusion, once passage through the intestinal epithelium, first-pass intestinal metabolism of this chemical might occur. It can undergo extensive metabolism in rat and human liver microsomes[2].
In vivo
Oral administration of cycloastragenol (CA) for 7 days attenuates depression-like behavior in experimental mice. Oral bioavailability of this compound is about 25.70% at 10 mg/kg. It is excreted through bile and feces and eliminated predominantly by the kidney in rats. It also might exist an enterohepatic circulation of this chemical in rats. It could be metabolized widely in vivo in rat. For oral administration the mean Tmax at 10 mg/kg, 20 mg/kg, and 40 mg/kg is 2.06±0.58 h, 1.48±0.36 h, and 2.35± 1.17 h. The t1/2 is 5.23±1.55 h, 7.33±3.03 h, and 6.06± 3.42 h, respectively. The mean absorption time of this compound at 10 mg/kg is 5.70± 1.62 h; the poor absorption could be caused by the low solubility. The pharmacokinetic parameters show no significant differences among the groups of 10, 20, and 40 mg/kg except for Cmax and AUC[2].
