Biological Activity

Description Saikosaponin A is a triterpene saponin derived from the medicinal plant, Bupleurum chinensis DC. (Umbelliferae). It has a variety of pharmacological benefits, including anti-inflammatory, immunomodulatory, and anti-bacterial activities.
In vitro

Saikosaponin A inhibited expression of glial fibrillary acidic protein and activation of rat hippocampal astrocytes induced by glutamate. It also decreased [Ca2+] and decreased the secretion of IL-6 from glutamate-activated rat hippocampal astrocytes[1].

In vivo Saikosaponin A demonstrated antiepileptic activity in a variety of in vivo seizure models including the pentylenetetrazole kindling model, the maximal electroshock (MES)-induced seizure model as well as the Li-Pilocarpine induced refractory epilepsy[1].

Calculation results:

Working concentration: mg/ml;

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.
