Description: T-1101 tosylate (also known as TAI95 tosylate) is a potent inhibitor of Hec1/Nek2 (Highly expressed in cancer 1 / NIMA-related kinase 2) with antitumor activity. T-1101 tosylate is inactive toward normal cells, kinases and hERG.

ProtocolIn VitroT-1101 tosylate reduces amounts of cell-cycle related proteins cyclin A1, cyclin B1, and cyclin D1. T-1101 tosylate (1 µM; 24 hours) induces apoptosis. T-1101 tosylate (1μM; 3-24 24 hours) decreases the level of Nek2 in a time-dependent manner. T-1101 tosylate disrupts the Hec1/Nek2 protein–protein interaction in the cells. T-1101 tosylate shows potent in vitro antiproliferative activity (IC50: 14.8-21.5 nM).
In VivoT-1101 tosylate (2.5 mg/kg; p.o.; twice per day) shows significant in vivo activity in mice bearing various human cancer xenografts. Oral co-administration of T-1101 tosylate (2.5 mg/kg; p.o.; twice per day) halves the dose of sorafenib (25 mg/kg to 12.5 mg/kg) required to exhibit comparable in vivo activity towards Huh-7 xenografts . T-1101 tosylate shows good oral bioavailability and thermal stability.

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 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.
