ProtocolIn VitroKRIBB11 blocks the induction of HSF27 downstream target proteins such as HSP70 and HSP1. KRIBB11 induces growth arrest and apoptosis in HCT-116 cells. KRIBB11 inhibits HSF1-dependent p-TEFb (positive transcriptional elongation factor b) recruitment to the hsp70 promoter
In VivoKRIBB11 (50 mg/kg, intraperitoneal injection) inhibited tumor growth in nude mice in 47.4% without weight loss

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 add µL PEG300, mix and clarify, next add µL Tween 80,mix and clarify, next add µL ddH2O,mix and clarify.
Note:
  • (1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
  • (2) Be sure to add the solvent(s) in order.
