Estradiol 3-sulfamate (BLE 00084; E2MATE; ES-J 995) is a potent, long-acting, and orally active steroid sulfatase inhibitor; inhibits estrone sulfatase with an IC50 of 251 nM and a Ki of 133 nM. IC50: 251 nM (estrone sulfatase)[1]Ki: 133 nM (estrone sulfatase)[1]
Introduction of a fluoro, chloro, or bromo moiety at the C-2 position of EMATE and Estradiol 3-sulfamate and that of a fluoro moiety at the C-4 position of the parent sulfamates markedly increase the estrone sulfatase inhibitory activity[1].
Estradiol 3-sulfamate is readily transformed and absorbed in the gut into its oxidative metabolite, EMATE, and both compounds have already been shown to be potent, long-acting, and orally active STS inhibitors[2].

DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL,
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL saline,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
