體內(nèi)研究
(In Vivo)

Irosustat 可有效抑制大鼠肝臟,濃度為 1 mg/kg 時(shí)抑制率 >90%。Irosustat (2 mg/kg,po 5 d) 阻斷卵巢切除大鼠中硫酸雌酮 (E1S) 刺激的子宮生長(zhǎng)。此外,Irosustat (2、10 mg/kg,口服) 加 E1S 可劑量依賴(lài)性地降低去卵巢大鼠中 NMU 誘導(dǎo)的乳腺腫瘤的生長(zhǎng)[1]。Irosustat (667 COUMATE;10 mg/kg,口服) 對(duì)大鼠肝臟中的類(lèi)固醇硫酸酯酶 (STS) 活性顯示出 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.
