Metodo per preparare la formulazione in vivo: Prendere μL DMSO liquido master, quindi aggiungereμL PEG300, mescolare e chiarire, quindi aggiungereμL Tween 80, mescolare e chiarire, quindi aggiungere μL ddH₂O, mescolare e chiarire.

Metodo per preparare la formulazione in vivo: Prendere μL DMSO liquido master, quindi aggiungere μL Olio di mais, mescolare e chiarire.

Nota: 1. Si prega di assicurarsi che il liquido sia limpido prima di aggiungere il solvente successivo.
2. Assicurarsi di aggiungere il/i solvente/i in ordine. È necessario assicurarsi che la soluzione ottenuta, nell'aggiunta precedente, sia una soluzione limpida prima di procedere all'aggiunta del solvente successivo. Metodi fisici come il vortex, gli ultrasuoni o il bagno d'acqua calda possono essere utilizzati per facilitare la dissoluzione.

Meccanismo d'azione (Mechanism of Action)

Caratteristiche	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.
Saggio chinasico	Attività antagonista del Glucocorticoid Receptor (GR), attività antagonista del Progesterone Receptor (PR)
Saggio chinasico	Saggio della fosfatasi alcalina T47D: le cellule di cancro al seno umano T47D vengono piastrate in piastre per coltura tissutale a 96 pozzetti a 10⁴ cellule per pozzetto in terreno di saggio [terreno RPMI senza rosso fenolo contenente 5% (v/v) di FBS trattato con carbone attivo e 1% (v/v) di penicillina-streptomicina]. Due giorni dopo, il terreno viene decantato e Mifepristone (RU-486) o il controllo viene aggiunto a una concentrazione finale in terreno di saggio fresco. Ventiquattro ore dopo, viene eseguito un saggio della fosfatasi alcalina utilizzando un kit SEAP. Il terreno viene decantato e le cellule vengono fissate per 30 minuti a temperatura ambiente con 5% (v/v) di formalina. Le cellule vengono lavate una volta a temperatura ambiente con 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.
