BHPI

Catalog No. T14553Cas No. 56632-39-4

BHPI is a potent ERα inhibitor that blocks nuclear estrogen–ERα-regulated gene expression effectively. It triggers sustained ERα-dependent activation of the endoplasmic reticulum (EnR) stress sensor, notably the unfolded protein response (UPR), and consistently inhibits protein synthesis. With an IC50 value targeting ERα, BHPI's mechanism involves the rapid hyperactivation of PLCγ on the plasma membrane in ERα(+) cancer cells, which produces inositol 1,4,5-triphosphate (IP3). This, in turn, opens EnR IP3R calcium channels, leading to a rapid depletion of EnR Ca(2+) stores. SIGNIFICANTLY, BHPI alters estrogen-ERα's usual effect of causing mild and transient UPR activation by inducing a severe and prolonged UPR activation, transforming the UPR from a protective to a toxic response.

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
