Opmerking: 1. Zorg ervoor dat de vloeistof helder is voordat u het volgende oplosmiddel toevoegt.
2. Zorg ervoor dat u het/de oplosmiddel(en) in de juiste volgorde toevoegt. U moet ervoor zorgen dat de verkregen oplossing, bij de vorige toevoeging, een heldere oplossing is voordat u verdergaat met het toevoegen van het volgende oplosmiddel. Fysische methoden zoals vortexen, echografie of een warmwaterbad kunnen worden gebruikt om het oplossen te bevorderen.

Werkingsmechanisme (Mechanism of Action)

Kenmerken	Mifepristone is the first approved medication for patients with endogenous cushing
Targets/IC₅₀/Ki	Bcl-2 Progesterone receptor (T47D cells) 0.2 nM Glucocorticoid receptor (A549 cells) 2.6 nM
In vitro	Mifepristone inhibit corticoid-induced transcription from a glucocorticoid response element (GRE)-linked luciferase reporter gene in the human lung carcinoma cell line A549. Moreover, this compound also blocks progesterone induction of alkaline phosphatase activity in the human breast cancer cell line T47D. It inhibits ovarian cancer cell growth of SK-OV-3 and OV2008 with IC50 of 6.25 μM and 6.91 μM, respectively. A recent study shows that this chemical induces caspase-1 over expression both in differentiated and undifferentiated caspase-1-embryonic stem cells.
Kinase Assay	Glucocorticoid receptor (GR) antagonist activiteit, Progesterone receptor (PR) antagonist activiteit
Kinase Assay	T47D alkalische fosfatase test: T47D menselijke borstkankercellen worden geplaatst in 96-well weefselkweekplaten met 10⁴ cellen per putje in assaymedium [RPMI-medium zonder fenolrood met 5% (v/v) met houtskool behandelde FBS en 1% (v/v) penicilline-streptomycine]. Twee dagen later wordt het medium gedecanteerd en wordt Mifepristone of controle toegevoegd in een eindconcentratie in vers assaymedium. Vierentwintig uur later wordt een alkalische fosfatase-test uitgevoerd met behulp van een SEAP-kit. Het medium wordt gedecanteerd en de cellen worden gedurende 30 minuten bij kamertemperatuur gefixeerd met 5% (v/v) formaline. De cellen worden eenmaal gewassen bij kamertemperatuur met Hanks
In vivo	Mifepristone can impair the growth of SK-OV-3 tumors in immunosuppressed mice at 0.5 mg/day and 1 mg/day. This compound inhibits the prostate weight significantly in the highest doses in vivo, and inhibits growth of the prostate gland produced by dihydrotestosterone (DHT) to a greater extent than the induction of atrophy and cell death in rats.
