Product Introduction

Bioactivity

Description	Spiramycin (Rovamycin) is a macrolide antibiotic produced by Streptomyces ambofaciens, effective against gram-positive aerobic pathogens, N. gonorrhoeae, and staphylococci, and is used to treat infections caused by bacteria and Toxoplasma gondii.
In vivo	Spiramycin acts by binding to the bacterial 50S ribosomal subunit, thereby inhibiting translocation. Its primary mechanism during translocation involves stimulating the dissociation of peptidyl-tRNA from the ribosome. The compound reduces the protective effect of anisomycin on 23S rRNA nucleotides. Spiramycin exhibits potent antibacterial activity against the genus Prevotella, Streptococcus mitis, Archaea, strains of Porphyromonas, and Bacteroides, with metronidazole enhancing its efficacy. At 30°C, Spiramycin can inhibit protein synthesis in wild-type cells but not kill mutant or wild-type cells. Treating lipopolysaccharide-stimulated human monocytes with Spiramycin and erythromycin increases the total production of IL-6 without affecting TNFα, IL-1α, or IL-1β production. Spiramycin inhibits protein synthesis by stimulating the dissociation of peptidyl-tRNA from ribosomes. It dose-dependently inhibits the proliferative response of human mononuclear cells stimulated by pulse-width modulation and polyhydroxyalkanoate esters. Additionally, Spiramycin induces a reduction in tritiated thymidine uptake, suggesting interference with an early stage of the cell cycle.

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, TargetMol | Animal experiments

and a total of 10 animals are to be administered, using a formulation of TargetMol | reagent

10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH₂O , the resulting working solution concentration would be 2 mg/mL.

Stock Solution Preparation:

Dissolve 2 mg of the compound in 100 μL DMSO TargetMol | reagent to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.

Preparation of the In Vivo Formulation:

1) Add 100 μL of the DMSO TargetMol | reagent stock solution to 400 μL PEG300 and mix thoroughly until the solution becomes clear.

2) Add 50 μL Tween 80 and mix well until fully clarified.

3) Add 450 μL Saline,PBS or ddH₂O TargetMol | reagent and mix thoroughly until a homogeneous solution is obtained.
