Mecanismo de acción (Mechanism of Action)

Características	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.
Ensayo de quinasa	Actividad antagonista del Glucocorticoid Receptor (GR), actividad antagonista del Progesterone Receptor (PR)
Ensayo de quinasa	Ensayo de fosfatasa alcalina T47D: las células de cáncer de mama humano T47D se siembran en placas de cultivo tisular de 96 pocillos a 10⁴ células por pocillo en medio de ensayo [medio RPMI sin rojo de fenol que contiene 5 % (v/v) de FBS tratado con carbón activado y 1 % (v/v) de penicilina-estreptomicina]. Dos días después, se decanta el medio y se añade Mifepristone (RU-486) o el control a una concentración final en medio de ensayo fresco. Veinticuatro horas después, se realiza un ensayo de fosfatasa alcalina utilizando un kit SEAP. El medio se decanta y las células se fijan durante 30 minutos a temperatura ambiente con 5 % (v/v) de formalina. Las células se lavan una vez 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.
