| Description | Eravacycline dihydrochloride (TP-434-046) is a potent and broad-spectrum antibacterial agent against six E. coli (MICs: 0.125-0.25 mg/L). |
| In vitro | Eravacycline shows inhibitory activity against A. baumannii, including isolates that are resistant to sulbactam, SM 7338, and BAY 41-6551(MIC50/90 = 0.5/1 mg/L)[1]. Eravacycline shows potent broad-spectrum activity against 90% of the isolates for all species panels (MIC90 0.008-2 μg/mL) except those of Pseudomonas aeruginosa and Burkholderia cenocepacia (MIC90 = 32 μg/mL). Eravacycline is active against multidrug-resistant bacteria including β-lactamases and antibiotics, including carbapenem resistance[4]. |
| In vivo | Eravacycline(3.125-50 mg/kg) shows mean fAUC/MIC magnitude associated with net stasis and 1-log kill endpoint of 27.97 and 32.60[2]. In mouse septicemia models, Eravacycline is efficacious against Staphylococcus aureus and demonstrates 50% protective dose values of ≤1 mg/kg. The PD50s are 1.2-4.4 mg/kg against Escherichia coli isolates[5]. |

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 
10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH2O , the resulting working solution concentration would be 2 mg/mL.Dissolve 2 mg of the compound in 100 μL DMSO 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.
1) Add 100 μL of the DMSO 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 and mix thoroughly until a homogeneous solution is obtained.
