Virginiamycin S1 is a novel, potent and naturally occurring cyclic hexadepsipeptide antibiotic that inhibits bacterial protein synthesis at the level of aminoacyl-tRNA binding and peptide bond formation. Virginiamycin S1 is produced by Streptomyces virginiae, and shows a strong bactericidal activity against a wide range of Gram-positive bacteria. Effective in treat multidrug-resistant bacterial infections.

Additional Infomation |
Virginiamycin S1 is a cyclodepsipeptide that is N-(3-hydroxypicolinoyl)-L-threonyl-D-alpha-aminobutyryl-L-prolyl-N-methyl-L-phenylalanyl-4-oxo-L-pipecoloyl-L-2-phenylglycine in which the carboxy group of the 2-phenylglycine moiety has undergone formal intramolecular condensation with the hydroxy group of the N-(3-hydroxypicolinoyl)-L-threonyl to give the corresponding 19-membered ring lactone. It is one of the two major components of the antibacterial drug virginiamycin, produced by Streptomyces virginiae, S. loidensis, S. mitakaensis, S. pristina-spiralis, S. ostreogriseus, and others. It has a role as an antibacterial drug and a bacterial metabolite. It is a cyclodepsipeptide and a macrolide antibiotic.
One of the components of virginiamycin, a cyclic polypeptide antibiotic complex from streptomyces virginiae, s. Loidensis, s. Mitakaensis, s. Pristina-spiralis, s. Ostreogriseus, and others. It is used to treat infections with gram-positive organisms and as a growth promoter in cattle, swine, and poultry. Virginiamycin factor S has been reported in Streptomyces virginiae with data available. Virginiamycin S1 is a streptomycin B-related cyclic depsipeptide isolated from the bacterium Streptomyces virginiae and other Streptomyces bacterial species. Virginiamycin S1 binds to and inhibits the formation of 50S ribosomes, thereby preventing protein synthesis. (NCI04) |

Solubility (In Vivo) |
Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80: Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 :Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] Oral Formulations
Oral Formulation 1: Suspend in 0.5% CMC Na (carboxymethylcellulose sodium) Oral Formulation 2: Suspend in 0.5% Carboxymethyl cellulose Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals).

Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
1 mM | 1.2138 mL | 6.0688 mL | 12.1375 mL | |
5 mM | 0.2428 mL | 1.2138 mL | 2.4275 mL | |
10 mM | 0.1214 mL | 0.6069 mL | 1.2138 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution 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 stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
