Se pueden utilizar métodos físicos como el vórtice, el ultrasonido o el baño de agua caliente para ayudar a la disolución.

Mecanismo de acción

Targets/IC₅₀/Ki	ER (Cell-free assay) 0.94 nM
In vitro	Fulvestrant es un inhibidor eficaz del crecimiento de células MCF-7 ER-positivas (con una IC50 de 0,29 nM) pero sin efecto sobre el crecimiento de células de cáncer de mama humanas BT-20 ER-negativas. Este compuesto causa la acumulación de células en G0/G1 y también reduce la proporción de células capaces de síntesis continua de ADN. Inhibe competitivamente la unión del estradiol al receptor de estrógeno. Este agente bloquea la localización nuclear del ER al alterar la dimerización del receptor y el transporte nucleocitoplasmático dependiente de energía. Debido a la inestabilidad del complejo fulvestrant-ER, la unión de este compuesto con el ER finalmente resulta en una degradación acelerada de la proteína ER. Este químico (10 nM) no solo disminuye los niveles de ARNm de IGF-IR, sino que también disminuye la vida media. El tratamiento con 100 μM de este compuesto conduce a un aumento dependiente del tiempo de los niveles de ARNm de TNFR1 y TRADD en estado estacionario en células MCF-7. Es capaz de regular a la baja la expresión del receptor de andrógenos y disminuye las respuestas androgénicas en células de cáncer de próstata humanas LNCaP. Este agente también atenúa significativamente el crecimiento estimulado por R1881 en un 70%. Es capaz de modular la mitosis y la muerte celular en neuronas cerebelosas inmaduras mediante la activación rápida de MAPK.
In vivo	Fulvestrant carece de actividad uterotrófica, y cuando se coadministra con estradiol, bloquea eficazmente la acción uterotrófica del estradiol con una ED50 de 0,06 mg/kg/día s.c. en ratas hembra inmaduras. Una única inyección s.c. de 5 mg de esta suspensión del compuesto bloquea completamente el crecimiento de xenoinjertos MCF-7. El crecimiento de los trasplantes del tumor mamario humano BrlO también se suprime eficazmente con 10 μM de este químico. Este compuesto (10 mg/rata, s.c.) reduce la expresión del receptor de andrógenos, la fosforilación de ERK1/2 y la proliferación celular en la próstata ventral de la rata. También muestra actividad anti-angiogénesis en la membrana corioalantoidea del huevo de gallina.

Preguntas frecuentes

Pregunta 1:
Is there any information for the half-life of it (Cat No.S1191)?

Respuesta:
Its half life, S1191, is about 13.5 to 18.5 hours in vivo: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2750771/. The half life of this compound in cell culture might be different and we generally recommend replenishing with fresh drug every 24-48 hours.
