Prinaberel
Based on 4 publication(s) in Google Scholar
Prinaberel (ERB-041) is a potent and selective estrogen receptor (ER) β agonist with IC50s of 5.4, 3.1 and 3.7 nM for human, rat and mouse ERβ, respectively. Prinaberel displays >200-fold selectivity for ERβ over ERα. Prinaberel is a potent skin cancer chemopreventive agent that acts by dampening the WNT/β-catenin signaling pathway. Prinaberel induces ovarian cancer apoptosis.

Prinaberel (ERB-041) (0-60 μM; 24 hours) treatment of human SCC cells induces cell differentiation, cell cycle arrest and reduces colony formation[2].
Prinaberel shows a marked reduction in the expression of inflammation regulatory proteins such as p-NFκBp65, iNOS and COX-2 in A431 cells. Prinaberel diminishes phosphorylated-PI3K and -AKT, which is associated with the enhancement in E-cadherin expression and reduction in migration of A431 cells[2].
Prinaberel (0.01-10 μM) inhibits cell proliferation in a dose- and time-dependent manner[3].
Prinaberel (10 μM; 48 hours) promotes ovarian cancer (SKOV-3 cells) apoptosis[3].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 5 mg/mL (18.43 mM); Clear solution
