Biological Activity

Description Esmolol (ASL8052) is a cardioselective b-blocker, used to control rapid heartbeats or abnormal heart rhythms.
Features The suppressive effects of ONO-1101 on cardiovascular performance are less than those of Esmolol at equipotent beta-blocking doses.
Targets
beta-adrenergic receptor [1]
In vitro
In vitro Esmolol contains one asymmetric centre and exists as an enantiomeric pair, the (-)-enantiomer is active and the (+)-enantiomer is inactive, which is analogous to other P-blockers that have an oxypropranolamine nucleus. Esmolol has a rapid onset and offset of activity, the primary site of activity of Esmolol is on sinus node and atrioventricular (AV) nodal conduction systems. [1]
In Vivo
In vivo Esmolol (20 mg/kg) infusion in sepsis improves oxygen utilization of myocardium and preserves myocardial function in septic rats. [2] Esmolol (5 mg/kg, i.v.) produces a dose-dependent decrease in heart rate (HR) in rabbits, with the maximum percent reductions of 13%. Esmolol (5 mg/kg, i.v.) produces a dose-dependent decrease in mean arterial pressure (MAP) in rabbits, with the maximum percent reductions of 38.2%. [3] Esmolol (300 mg/kg) significantly decreases the heart rate, rate-pressure product, left ventricular contraction, cardiac output, and relative refractory period of the right ventricle, suppresses the AV nodal conduction, and increases the effective refractory period of the right ventricle and the preload of the left ventricle in canine. Esmolol (300 mg/kg) significantly reduces the isoproterenol-induced increase in heart rate and ventricular contraction in canine. [4]

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.
