Alias 15-keto-PGE2

15-keto-Prostaglandin E2 is an endogenous bioactive metabolite that inhibits STAT3 activation through covalent interaction with the Cys259 residue, while also binding to and stabilizing EP2 and EP4 receptors, thereby exerting inhibitory effects on breast cancer cell growth and tumor progression, activating PPAR-γ signaling, and promoting fungal growth, collectively positioning this lipid mediator as a multifunctional regulator in cancer biology, immunometabolism, and host–pathogen interaction research.

Product Introduction

Bioactivity

Description	15-keto-Prostaglandin E2 is an endogenous bioactive metabolite that inhibits STAT3 activation through covalent interaction with the Cys259 residue, while also binding to and stabilizing EP2 and EP4 receptors, thereby exerting inhibitory effects on breast cancer cell growth and tumor progression, activating PPAR-γ signaling, and promoting fungal growth, collectively positioning this lipid mediator as a multifunctional regulator in cancer biology, immunometabolism, and host–pathogen interaction research.
In vivo	In a mouse xenograft model using MDA-MB-231 cells, intraperitoneal (i.p.) injection of 15-keto-Prostaglandin E2 suppressed tumor growth, resulting in reduced tumor volume and weight. This reduction correlates with the downregulation of p-STAT3 and Cyclin D1 levels in the tumor tissues [1].
Synonyms	15-keto-PGE2

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.
