Product Introduction

L-Threonine AI Summary

L-Threonine, with a partition coefficient (logP) value of 2.91, demonstrates moderate to high hydrophobicity. It has shown significant bioactivity by inhibiting Phenylalanine dehydrogenase of Sporosarcina species by 61.0%, and it has antiviral properties, notably blocking the entry of the Ebola virus with AC50 values ranging from 316.2 nM to 6.31 uM. Additionally, it inhibits the cytotoxic effects of SARS-CoV-2 on VERO-6 and Caco-2 cells at 10 uM concentration, although the potency varies, with inhibition rates of -1.21% and 0.21% respectively. It also inhibits the SARS-CoV-2 3CL-Pro protease activity by 8.188% at a concentration of 20 µM. In rat hippocampal astrocytes, L-Threonine inhibits ASCT2 mediated [3H]-D-serine uptake by 25.0% at 1 mM concentration. Despite these activities, it did not exhibit significant bioactivity against numerous human and rat receptor and enzyme targets in various assays, with AC50 values exceeding 30000.0 nM. Furthermore, L-Threonine has an Rf value of 0.54 under specified chromatographic conditions, which provides useful insights into its chromatographic behavior. In human HDAC6 enzymatic assays, higher inhibition was observed using a commercial peptide substrate compared to a custom one, and a 20.0% inhibition was recorded against PKM2 of unknown origin..

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:

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.

Stock Solution Preparation:

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.

Preparation of the In Vivo Formulation:

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.

This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.

All co-solvents required for this protocol, includingDMSO, PEG300/PEG400, Tween 80, SBE-β-CD, and Corn oil, are available for purchase on the TargetMol website.
