Alias Y 134

Y134 is an estrogen receptor inhibitor that is selective and orally active, exhibiting strong antagonist activity against ERα and Erβ with Ki of 0.09 nM and 11.31 nM, respectively. The selectivity of Y134 for ERα is 121.1 times higher than that for ERβ. Y134 inhibited the proliferation of ER positive human breast cancer cells stimulated by estrogen.

Product Introduction

Bioactivity

Description	Y134 is an estrogen receptor inhibitor that is selective and orally active, exhibiting strong antagonist activity against ERα and Erβ with Ki of 0.09 nM and 11.31 nM, respectively. The selectivity of Y134 for ERα is 121.1 times higher than that for ERβ. Y134 inhibited the proliferation of ER positive human breast cancer cells stimulated by estrogen.
Targets&IC50	ERβ:11.31 nM (Ki), ERα:0.09 nM (Ki)
In vitro	Y134 displays robust antagonistic effects on estrogen receptors (ERs) in CV-1 cells co-transfected with plasmids carrying ERα or ERβ along with estrogen-response element-driven luciferase, resulting in a significant decrease in luciferase activity.[1] Treatment with Y134 (0.01 nM-10 μM; 6 d) effectively suppresses the proliferation of ER-expressing breast cancer cells (MCF-7 and T47D) stimulated by estrogen.[1]
In vivo	Administration of Y134 (1-3 mg/kg/day; p.o. for 3 days) completely eliminates the estrogen-induced growth of terminal end buds (TEB) in the mammary glands of ovariectomized rats. Y134 exhibits a dose-dependent inhibition of uterine cell proliferation induced by estrogen (E2). [1]

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.
