Background

Kongensin A is a natural product isolated from Croton kongensis. Kongensin A is an effective, covalent HSP90 inhibitor that blocks RIP3-dependent necroptosishas. Kongensin A is a potent necroptosis inhibitor and an apoptosis inducer. Kongensin A has potential anti-necroptosis and anti-inflammation applications[1].

Kongensin A (0-15 μM; 6 hours; HT29 cells) treatment induces caspase activation and apoptosis in multiple cancer cell lines in a dosage-dependent manner[1].Kongensin A (0-15 μM; 24 hours; HT29 cells) treatment induces the degradation of RIPK1 and oncogenic kinases such as ERBB2, AKT, EGFR, and B-raf, and induces the up-regulation of HSP90A and HSP90B[1].Kongensin A covalently binds to cysteine 420 in the middle domain of HSP90 and dissociates HSP90 from its cochaperone CDC37. The HSP90-CDC37 complex is required for RIP3 activation, KA blocks LPS/Smac mimetics/Z-VAD and RIP3 polymerization-induced cell death, in which cell death is dependent on RIP3 but not its upstream kinase RIP1[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.
3. All of the above co-solvents are available for purchase on the GlpBio website.
