Sulfamerazine

Catalog No. T0913Cas No. 127-79-7
Alias RP2632

Sulfamerazine (RP2632) is a long-acting sulfanilamide antibacterial agent. Sulfamerazine inhibits bacterial synthesis of dihydrofolic acid by competing with para-aminobenzoic acid (PABA) for the binding site on dihydropteroate synthase.

Product Introduction

Bioactivity
Description
Sulfamerazine (RP2632) is a long-acting sulfanilamide antibacterial agent. Sulfamerazine inhibits bacterial synthesis of dihydrofolic acid by competing with para-aminobenzoic acid (PABA) for the binding site on dihydropteroate synthase.
In vitro
Sulfamerazine significantly affects the lifespan of rats, markedly prolonging the life of male hamsters. The maximum body weight of all rats fed with sulfamerazine exceeded that of the control group. After oral administration of sulfamerazine, significant alterations in the shape of the concentration-time curve due to age were observed, strongly indicating absorption deficiencies within the first week after birth in lambs.
In vivo
Sulfamerazine exhibits a bi-exponential decay in water and a tri-exponential decay in cyclodextrin (CD) solutions. The resonance of aromatic protons in Sulfamerazine indicates a significant upfield shift, suggesting that the aniline ring is deeply encapsulated within the CD cavity.

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
For Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
