Irosustat (667 COUMATE) 是一种有效的类固醇硫酸酯酶抑制剂,IC50 为 8 nM[1]。Irosustat (667 COUMATE) 抑制 MCF-7 细胞中的类固醇硫酸酯酶 (STS) 活性,IC50 为 0.2 nM,但在 10 μM< 时对 MCF-7 细胞的形态或增殖没有影响[2]

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究
(In Vivo)

Irosustat 可有效抑制大鼠肝脏,浓度为 1 mg/kg 时抑制率 >90%。Irosustat (2 mg/kg,po 5 d) 阻断卵巢切除大鼠中硫酸雌酮 (E1S) 刺激的子宫生长。此外,Irosustat (2、10 mg/kg,口服) 加 E1S 可剂量依赖性地降低去卵巢大鼠中 NMU 诱导的乳腺肿瘤的生长[1]。Irosustat (667 COUMATE;10 mg/kg,口服) 对大鼠肝脏中的类固醇硫酸酯酶 (STS) 活性显示出 97.9 ± 0.06% 的抑制作用[2]

Cell Assay
[2]

MCF-7 cells are cultured in growth medium (minimum essential medium (MEM) containing, phenol red, 10% foetal calf serum (FCS) and essential nutrients). When the cells reach 60% confluency, they are treated with Irosustat (0.001-10 μM) in growth medium. After 72 h of incubation, photographs are taken under normal conditions of light and the number of attached cells in each flask is determined using a Coulter cell counter[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Administration
[1]

Rats[1]
Ludwig rats bearing mammary tumors are used in the assay. Tumor development is monitored, and animals are ovariectomized when tumors reach 0.8-1.5 cm in diameter. Tumors are allowed to regress over a 12- to 13-day period to confirm their hormone-dependent status. Regrowth of tumors is stimulated with oestrone sulfate (E1S; 50 μg/day, s.c.). When tumors have regrown, animals continue to receive either E1S alone or E1S plus Irosustat at 10 mg/kg/day or 2 mg/kg/day, p.o., until tumor regression has occurred. Tumor volumes are calculated from two measured diameters[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
