Description: Erteberel, also known as LY500307, is a selective estrogen receptor beta (ERβ) agonist that was developed for the treatment of benign prostatic hyperplasia. LY500307 was well tolerated in BPH patients with LUTS at doses up to 25 mg once daily for 24 weeks. The study was terminated early because of inadequate efficacy.

More Info:
Biological target: | Erteberel (LY500307) is an estrogen receptor beta (ERβ) agonist with Ki and EC50 of 1.54 nM and 3.61 nM, respectively. |
In vitro activity: | Treatment with LY500307 significantly reduced the viability of various GBM cell lines in a dose-dependent manner. In contrast, viability of normal astrocytes was not affected at the tested doses, suggesting that LY500307 has tumor cell–specific activity (Fig. 1a). Cell Titer-Glo luminescent cell viability assays revealed that LY500307 reduced the viability of various patient-derived GBM cells in a dose dependent manner (Fig. 1b). As shown in Fig. 1c, LY500307 significantly reduced the colony formation of U87 and U251 GBM cells. LY500307 significantly induced Annexin V-positive apoptotic cells in U87, U251 (Fig. 1d,e) and patient derived primary GBM (GBM10) cells (Supplementary Fig. 1b). Collectively, these results suggested that LY500307 has potential to selectively reduce cell viability, decrease survival and induce apoptosis of GBM cells.

In vivo activity: | In detail, the number of lung metastatic nodules in mice of the 4T1 model treated with LY500307 was significantly lower than that in mice of the 4T1 model treated with control (Fig. 1B; P < 0.05). Moreover, the overall survival in the LY500307 treatment group of the 4T1 murine model was significantly longer than that of the control group (Fig. 1C; P < 0.05).
