Chemical Properties
| Description | Isovalerylshikonin is a natural product from Arnebia euchroma |
| Targets&IC50 | S. aureus:16 mg/L(MIC) |
| In vitro | Isovalerylshikonin exhibited marginal antibacterial activity against drug-resistant Staphylococcus aureus RN4220, with an MIC of 16 mg/L[1]. |
| In vivo | A peritonitis/sepsis model was employed to test the in vivo synergistic activity of IVS and STM. IVS synergistically decreased the bacteria count with STM in peritoneal, spleen and liver, and increased mouse survival with STM in 7 days. The acute toxicity of IVS was tested, and the LD50 of IVS with a single exposure was 2.584 g/kg in mice. Overall, isovalerylshikonin, a low toxicity resistance-modifying agent, exhibited synergistic antibacterial activities in vitro and in vivo against drug-resistant S. aureus. The effects were mediated by suppression of msrA mRNA expression and bacterial efflux[1]. |

Calculator
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:
For example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . A total of 10 animals were administered, and the formula you used is 5% 
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 DMSO (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.
(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 DMSO main solution, add 300 μLPEG300 mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2O mix well and clarify
main solution, add 300 μLPEG300 mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2O mix well and clarifyFor Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
