Biological Activity

Description Sulfamerazine (RP 2632) is a sulfonamide antibacterial.
In vitro

Sulfamerazine exhibits biexponential decay in water and triexponential decay in cyclodextrins solutions. Sulfamerazine shows remarkably upfield shift in the complexes suggested that the aniline ring deeply encapsulated in the CD cavity. [1]

In vivo Sulfamerazine results in a marked evolution in the shape of the concentration-time curves in function of age, strongly suggesting a defective absorption rate in the first weeks after birth in lambs. [2] Sulfamerazine has a significantly beneficial effect on life span of rats and apparently increases that of male hamsters, and all rats fed sulfamerazine attains higher maximum weights than their controls.

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.
