Product Introduction

Bioactivity

Description	Harringtonine is a naturally occurring alkaloid that inhibits DNA synthesis and protein synthesis and strongly kills S-phase cells. Harringtonine has antitumor and antiviral activities.
Targets&IC50	HeLa cells:4 μM, HSV1:0.1081-0.1584 μM, CHIKV:0.24 μM (EC50), BHK-21 cells:0.24 μM (EC50), HL-60 cells:0.047 μM
In vitro	Harringtonine inhibits the elongation phase of translation by preventing substrate binding to the acceptor site on the 60-S ribosome subunit, blocking aminoacyl-tRNA binding and peptide bond formation [1]. It displays potent inhibition of Chikungunya virus infection (EC50: 0.24 μM) and could inhibit other alphaviruses [2]. Additionally, Harringtonine inhibits the growth of human myeloid leukemia cells in vitro at low concentrations [3].
In vivo	METHODS: To study in vivo activity, Harringtonine (0.5-4 mg/mouse) was injected retroorbital into C57BL/6 mice. RESULTS: Within 5 min, Harringtonine completely depleted multimers in all organs except testis and brain, and it took up to 30 min to significantly reduce the number of multimers due to the blood-brain and blood-testis barriers. [3]

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, TargetMol | Animal experiments

and a total of 10 animals are to be administered, using a formulation of TargetMol | reagent

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 TargetMol | reagent 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 TargetMol | reagent 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 TargetMol | reagent 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.
