Acetylspiramycin
Based on 2 publication(s) in Google Scholar
Acetylspiramycin (Spiramycin B) is an effective oral macrolide antibiotic produced by Streptomyces, It can inhibit the splenic lymphocyte transformation induced by phytohemagglutinin (PHA), LPS (HY-D1056) and antigen, reduce the procoagulant activity of macrophages, have good antibacterial effect on gram-positive bacteria, and is also an effective antigenic insect agent, which can be used to fight parasitic infection.

Macrolide |
Acetylspiramycin (0-40 μg/mL, 0-72 h) can dose-dependently inhibit lymphocyte proliferation in spleen cell culture medium supplemented with plant hemagglutinin (PHA, 10 μg/mL), and the extent of its effect depends on the time of addition[3].
Acetylspiramycin (25-100 μg/ml, 18 h) can reduce the phagocytosis of mouse peritoneal macrophages and has reversible toxicity to macrophages in vitro[4].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:Spleen cells were cultured with PHA (10 μg/mL)
-
Concentration:0-40 μg/mL
-
Incubation Time:0-72 h
-
Result:Inhibited 3HT incorporation in a dose-dependent manner.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (2.82 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
