SB-743921

Synonyms: SB-921

SB-743921 (SB-921) is an inhibitor of Kinesin Spindle Protein (KSP), a mitotic protein essential for cell cycle control and motility. It functions by selectively targeting rapidly dividing cells and disrupting spindle formation during cell division, leading to G2/M phase arrest and ultimately causing cell death. It also inhibits proliferation and induces apoptosis in diffuse large B-cell lymphoma (DLBCL) cell lines.

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.
