Alias Silibinin B

Silybin B (Silibinin B) is an effective inhibitor of raloxifene 4 '- and 6-glucosalylation, an effective anti-fibrinogenic and anti-oligomeric component of Silymarin, with free radical scavenging activity of 1, 1-diphenyl-2-pyridinyl hydrazine (DPPH), and a protective effect against cisplatin-induced neurotoxicity by alleviating DNA damage and apoptosis. Silybin B can inhibit the growth of human chronic myeloid leukemia K562 cells and induce apoptosis.

Product Introduction

Bioactivity

Description	Silybin B (Silibinin B) is an effective inhibitor of raloxifene 4 '- and 6-glucosalylation, an effective anti-fibrinogenic and anti-oligomeric component of Silymarin, with free radical scavenging activity of 1, 1-diphenyl-2-pyridinyl hydrazine (DPPH), and a protective effect against cisplatin-induced neurotoxicity by alleviating DNA damage and apoptosis. Silybin B can inhibit the growth of human chronic myeloid leukemia K562 cells and induce apoptosis.
In vitro	The present study assessed the effects of the diastereoisomers on cell apoptosis, and compared these with their mixture, silybin, in human chronic myeloid leukemia K562 cells. Both isomers showed stronger effects on cell growth inhibition and apoptosis induction than silybin. Compared with Silybin B, silybin A showed higher effects on the production of intracellular reactive oxygen species and Ca2+.[1]
In vivo	Silybin B markedly improved the behavioral abnormalities in cisplatin-treated mice and reduced LPO levels while increasing SOD, GSH, and T-AOC in mice brain tissue. Nissl staining and Tunel assay showed that silybin B alleviated cisplatin-induced hippocampal damage.[2]

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, TargetMol | Animal experiments

and a total of 10 animals are to be administered, using a formulation of TargetMol | reagent

10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH₂O , the resulting working solution concentration would be 2 mg/mL.

Stock Solution Preparation:

Dissolve 2 mg of the compound in 100 μL DMSO TargetMol | reagent to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.

Preparation of the In Vivo Formulation:

1) Add 100 μL of the DMSO TargetMol | reagent stock solution to 400 μL PEG300 and mix thoroughly until the solution becomes clear.

2) Add 50 μL Tween 80 and mix well until fully clarified.

3) Add 450 μL Saline,PBS or ddH₂O TargetMol | reagent and mix thoroughly until a homogeneous solution is obtained.

This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.

All co-solvents required for this protocol, includingDMSO, PEG300/PEG400, Tween 80, SBE-β-CD, and Corn oil, are available for purchase on the TargetMol website.
