ProtocolIn VitroThe specific binding of [125I]-angiotensin II to VSMC is inhibited by Losartan Carboxylic Acid (E-3174) with an IC50 of 1.1 nM. Losartan Carboxylic Acid abolishes the angiotensin II-induced formation of inositolphosphates in VSMC. Losartan Carboxylic Acid inhibits the angiotensin II-induced elevation of intracellular cytosolic Ca2+ concentration with an IC50 of 5 nM. Losartan Carboxylic Acid is more effective than losartan in blocking the angiotensin II-induced increase in Egr-1 mRNA. Losartan Carboxylic Acid inhibits the angiotensin II-induced cell protein synthesis with an IC50 of 3 nM

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.
