In Vivo Dissolution Calculator

(2R,3R)-Butane-2,3-diol is a non-covalent, reversible agonist targeting lanthanum (La³⁺)-sensitive calcium channels in bacteria (e.g., Escherichia coli) with an EC₅₀ of approximately 25 mM. (2R,3R)-Butane-2,3-diol binds to calcium channel proteins or related complexes, induces channel opening, promotes extracellular calcium influx, and triggers intracellular calcium transients, which may regulate bacterial physiological activities such as growth, metabolism, and signal transduction. (2R,3R)-Butane-2,3-diol mediates bacterial-host cell signaling interactions and affects the metabolic balance of intestinal microorganisms, and can be used to study lactose intolerance and other related diseases.

Description

IC₅₀ & Target

La³⁺-sensitive calcium channel

25 mM (EC₅₀)

In Vitro

(2R,3R)-Butane-2,3-diol (100 mM; 1-2 min) significantly induces a rapid increase in intracellular free Ca²⁺ concentration in the Escherichia coli intracellular calcium transient assay, with the peak value increasing by about 1-2 μM compared with the control group, and this effect is dependent on the external Ca²⁺ concentration (0.1-10 mM)^[1].
(2R,3R)-Butane-2,3-diol (5-200 mM; 5 min) activates the E. coli Ca²⁺ channel in a dose-dependent manner in the concentration-dependent assay, with EC₅₀ of about 25 mM. Under the condition of 10 mM external Ca²⁺, the peak intracellular Ca²⁺ could reach 25 μM^[1].

In Vivo:

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.

Protocol 1

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (27.74 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 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
Protocol 2

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 2.5 mg/mL (27.74 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.
Protocol 3

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 1.72 mg/mL (19.09 mM); Clear solution

This protocol yields a clear solution of ≥ 1.72 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (17.2 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.
