Product Introduction

Bioactivity

Description	Irosustat (667-Coumate) is a potent steroid sulfatase inhibitor, with an IC50 of 8 nM, and exhibits anti-breast cancer activity.
Targets&IC50	Steroid sulfatase:IC50:8 nM, Steroid sulfatase (MCF-7 cells):0.2 nM
In vitro	Irosustat (667 COUMATE), a potent steroid sulfatase inhibitor, exhibits an IC50 of 8 nM and inhibits steroid sulfatase (STS) activity in MCF-7 cells with an IC50 of 0.2 nM, without affecting the morphology or proliferation of MCF-7 cells at 10 μM.
In vivo	Irosustat effectively inhibits over 90% of rat liver activity at a concentration of 1 mg/kg. At doses of 2 mg/kg administered orally for five days, it impedes uterine growth induced by oestrone sulfate (E1S) in ovariectomized rats. Additionally, when combined with E1S, Irosustat, at dosages of 2 and 10 mg/kg administered orally, reduces the growth of NMU-induced mammary tumors in these rats in a dose-dependent manner. Moreover, at a dosage of 10 mg/kg administered orally, Irosustat (identified as 667 COUMATE) achieves a 97.9 ± 0.06% inhibition of steroid sulphatase (STS) activity in rat liver.
Cell Research	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
Animal Research	Irosustat is formulated in propylene glycol.RatsLudwig 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.

Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, TargetMol | Animal experiments

and a total of 10 animals are to be administered, using a formulation of TargetMol | reagent

10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH₂O , the resulting working solution concentration would be 2 mg/mL.

Stock Solution Preparation:

Dissolve 2 mg of the compound in 100 μL DMSO TargetMol | reagent to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.

Preparation of the In Vivo Formulation:

1) Add 100 μL of the DMSO TargetMol | reagent stock solution to 400 μL PEG300 and mix thoroughly until the solution becomes clear.

2) Add 50 μL Tween 80 and mix well until fully clarified.

3) Add 450 μL Saline,PBS or ddH₂O TargetMol | reagent and mix thoroughly until a homogeneous solution is obtained.
