Product Introduction

Bioactivity
Description
UT-155 is a selective and potent antagonist of the androgen receptor (AR) with a binding affinity (Ki) of 267 nM for the AR ligand-binding domain (AR-LBD).
Targets&IC50
AR-LBD:267 nM (Ki)
In vitro
UT-155 binds to the AR-LBD (Ki: 267 nM) and potently inhibits R1881-induced wildtype AR transactivation with 6-10-fold higher potency than enzalutamide. While UT-155 antagonizes both wildtype and mutant ARs comparably, enzalutamide's efficacy is halved against the W742L mutant AR. In LNCaP cells, UT-155 inhibits PSA and FKBP5 gene expression induced by 0.1 nM R1881 at concentrations between 10 and 100 nM, demonstrating 5-10 times better efficacy than enzalutamide.
In vivo
Consistent with its anti-proliferative effects in vitro, UT-155 significantly inhibits the growth of 22RV1 xenografts by 53%, while enzalutamide has no effect. In UT-155-treated animals, tumor weights, PSA levels, and expression of AR and AR-SV are significantly reduced.

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
For Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
