Reuterin is a glycerol metabolite originally isolated from L. reuteri, a bacteria found in the intestines of humans, that has antibacterial activity.1 It is produced by L. reuteri during exposure to live or UV-killed E. coli.2 Reuterin is active against E. coli and several species of Bacteroides, Bifidobacterium, and Eubacterium (MICs = 1.9-15 mM) as well as C. difficile and B. vulgatus (MICs = <1.9 mM for both).3 It enhances increases in the production of reactive oxygen species (ROS) and cell death induced by vancomycin or metronidazole in C. difficile when used at a concentration of 2.5 mM.4 Reuterin alters the bacterial composition of, and volatile organic compounds (VOCs) produced by, the mouse fecal microbiome.5

Step 2: Enter the in vivo formulation (This is only the calculator, not formulation. Please contact us first if there is no in vivo formulation at the solubility Section.)

% DMSO % % Tween 80 % ddH2O

Calculation results:

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid 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 master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
3. All of the above co-solvents are available for purchase on the GlpBio website.
