Triptolide Hsp90 Middle Domain Inhibitor

Name: Triptolide
Brand: Selleck Chemicals
SKU: S3604
Rating: 5 (47 reviews)

Cat. No.S3604

Triptolide es un triepóxido diterpénico, un agente inmunosupresor extraído de la hierba china Tripterygium wilfordii. Funciona como un inhibidor de NF-κB con doble acción al interrumpir la interacción p65/CBP y al reducir la proteína p65. Triptolide (PG490) anula la función de transactivación del factor de transcripción de choque térmico 1 (HSF1). Triptolide inhibe MDM2 e induce la apoptosis a través de una vía independiente de p53.

Mecanismo de acción (Mechanism of Action)

Targets/IC₅₀/Ki	NF-κB HSF1 MDM2
In vitro	Triptolide es un triepóxido diterpénico con potentes propiedades inmunosupresoras y antiinflamatorias. Se ha demostrado que este compuesto inhibe la expresión de IL-2 en células T activadas a nivel del factor purina-box/nuclear y la activación de la transcripción mediada por NF-κB. Inhibe la proliferación y formación de colonias de células tumorales a concentraciones extremadamente bajas (2–10 ng/mL). Este químico tiene una actividad inhibitoria sobre las células de cáncer de mama, estómago y la línea celular de leucemia HL-60. Induce la apoptosis en células tumorales al bloquear la activación de NF-κB y sensibilizar las células tumorales a la muerte celular programada inducida por TNF-α.
In vivo	Triptolide sinergiza con ciclosporina A en la promoción de la supervivencia del injerto en modelos animales y en la supresión de la enfermedad de injerto contra huésped en trasplantes alogénicos de médula ósea. Además, induce la apoptosis en células tumorales y potencia la inducción de apoptosis por el factor de necrosis tumoral (TNF-α) en parte a través de la supresión de la inducción de c-IAP2 y c-IAP1. El tratamiento con este compuesto durante 2–3 semanas inhibe el crecimiento de xenoinjertos formados por cuatro líneas celulares tumorales diferentes (melanoma B16, cáncer de mama MDA-435, cáncer de vejiga TSU y carcinoma gástrico MGC80-3), lo que indica que TPL tiene un amplio espectro de actividad contra tumores que contienen tanto formas de p53 de tipo salvaje como mutantes. Además, inhibe la metástasis experimental de células B16F10 a los pulmones y bazos de ratones. Tiene actividades in vitro e in vivo contra modelos murinos de enfermedad renal poliquística. LD50: Ratones 0,83 mg/kg (i.v.).
