| Cell experiment [1]: | |
Cell lines | HepG2 cells |
Preparation Method | HepG2 cells were plated in 12-well plates. Then, Estradiol Benzoate were added at final concentrations of 35µM, 55µM, and 75µM for two days, while 1% DMSO DMEM was used as the control group. |
Reaction Conditions | 35, 55, 75µM; 2d |
Applications | Estradiol Benzoate significantly reduced the production of HBeAg, HBsAg, HBV pgRNA, and HBV DNA in a dose-dependent manner and inhibited HBV activity. |
| Animal experiment [2]: | |
Animal models | Ovariectomy (Ovx) |
Preparation Method | One week after ovariectomy (Ovx), ICR female mice received daily injection of Estradiol Benzoate (20, 100, 200µg/kg; sc) for 4-5 weeks. Spatial memory was then tested in the water maze, and the overall locomotor activity was monitored in open field. |
Dosage form | 20, 100, 200µg/kg; sc; 4-5 weeks |
Applications | Estradiol Benzoate replacement effectively normalized the changes induced by Ovx, reducing the width of the synaptic cleft, enlarging the thickness of postsynaptic density (PSD), and increasing the number of synaptic vesicles in the presynapse in both cerebral cortex Fr1 and hippocampus CA1 areas. |

Estradiol Benzoate is a HBx protein inhibitor and inhibits androgen and hepatitis B virus (HBV) transcription, replication. Estradiol Benzoate shows antifertility effects, anti- Toxoplasma gondii activity and can improve memory behavior of Ovariectomy (Ovx) female mice[1][2][3][4].
Estradiol Benzoate (0-500µM; 48h) delays or stops the cell cycle of tachyzoites by blocking progression from G1 to S phase in HFF cells[1]. Estradiol Benzoate (35-75µM; 2d) significantly reduced the production of HBeAg, HBsAg, HBV pgRNA, and HBV DNA in HepG2 cells in a dose-dependent manner and inhibited HBV activity[2].
After male mice were exposed to Estradiol Benzoate (5, 10mg/kg, SC), as the concentration of Estradiol Benzoate increased, the number of TUNEL-positive cells in the testes of Estradiol Benzoate-treated mice significantly increased, and pro-apoptotic factors (Fas, TNF, Cytochrome C , Apaf1, Chop, Caspase-3, Caspase-8, Caspase-9 and Caspase-12) and estrogen receptor (ER) signaling pathway key genes (ER α, ER β, Erk1/2, Hsp90 and DAX-1) The mRNA expression level of was significantly up-regulated in the testis of the treatment group[3]. In an ovariectomy model, Estradiol Benzoate (20-200µg/kg for 4-5weeks) effectively normalised ovariectomy-induced changes in female rats, including a reduction in the width of the synaptic gap, an expansion in the thickness of the postsynaptic dense substance (PSD) and an increase in the number of presynaptic mid-synaptic vesicles in the Fr1 and hippocampal CA1 regions of the cerebral cortex[4].

Estradiol Benzoate（0-500µM；48h）通过阻断HFF细胞从G1期到S期的进展来延迟或停止弓形虫速殖子的细胞周期[1]。Estradiol Benzoate（35-75µM；2d）以剂量依赖性的方式显著降低HepG2 细胞中HBeAg、HBsAg、HBV pgRNA和HBV DNA的产生，并抑制 HBV活性[2]。
雄性小鼠暴露于Estradiol Benzoate（5、10mg/kg）后，随着Estradiol Benzoate浓度的增加，Estradiol Benzoate组小鼠睾丸中TUNEL阳性细胞数显著增加，促凋亡因子(Fas、TNF、细胞色素C、Apaf1、Chop、Caspase-3、Caspase-8、Caspase-9和Caspase-12)和雌激素受体(ER)信号通路关键基因(ERα、ERβ、Erk1/2、Hsp90和DAX-1)的mRNA表达水显著上调[3]。在卵巢切除模型中，Estradiol Benzoate（20-200µg/kg，4-5weeks）有效地使雌性大鼠卵巢切除引起的变化正常化，包括减少突触间隙的宽度，扩大突触后致密物（PSD）的厚度，并增加大脑皮层Fr1和海马CA1区突触前中突触小泡的数量[4]。
