描述 | The steroid sulfatase hydrolyses estrone sulfate and plays a key role in the regulation of estrogenic steroid formation. The inhibition of steroid sulfatase is an important therapeutic strategy for the treatment of postmenopausal women with breast cancer. Irosustat is a potent inhibitor of steroid sulfatase with an IC50 value of 8nM in a placental microsome assay. It is an orally active, irreversible, and nonsteroidal inhibitor. A single dose of irosustat (10mg/kg, p.o.) inhibited estrone sulfatase activity in rat liver by 93%. Administration of irosustat (2mg/kg, p.o.) for 5 days inhibited estrone sulfate-stimulated growth of uteri in ovariectomized rats. Irosustat (2 and 10mg/kg, p.o.) also suppressed estrone sulfate-stimulated tumor growth in a dose-dependent manner[3]. |

溶解方案 |
DMSO: 105 mg/mL(339.43 mM),配合低频超声助溶,注意:DMSO长时间开封后,会吸水并导致溶解能力下降,请避免使用长期开封的DMSO 以下溶解方案都请先按照体外实验的方式配制澄清的储备液,再依次添加助溶剂: ——为保证实验结果的可靠性,澄清的储备液可以根据储存条件,适当保存;体内实验的工作液,建议现用现配,当天使用; 以下溶剂前显示的百分比是指该溶剂在终溶液中的体积占比;如在配制过程中出现沉淀、析出现象,可以通过加热和/或超声的方式助溶
