Description of ML334

ML334 es un potente activador de NRF2 permeable a las células. Se logró a través de la inhibición de la interacción proteína- proteína Keap1-NRF2. Demuestra una afinidad de unión a Keap1 con una constante de disociación (Kd) de 1 μM en ensayos de resonancia de plasma de superficie competitiva (SPR). Además, ML334 compite con un péptido Nrf2, exhibiendo un IC50 de 1.6 μM en ensayo de polarización de fluorescencia (FP)[1-3].

ML334(100 μM; 3 horas) induce la expresión y translocación nuclear del factor nuclear (derivado del eritroide 2)-like 2 (NRF2) en las células HEK293. Mientras tanto, el tratamiento ML334 indujo la expresión de las proteínas HO-1 y TRX1 en las células HEK293[4]. La sobreexpresión de Nrf2 inducida por ML334 (50 μM; 48 horas) aumenta el efecto antifibrosco de la saponina panaxatriol (PTS) en fibroblastos cardíacos[5].

Modelos animales

Método de preparación

Un péptido de 16 mer biotinylado de la región de unión Keap1 de Nrf2 fue capturado por estreptavidina en una superficie de chip CM5 (300 RU). Una solución que contenía 40 nM del dominio Kelch de la proteína Keap1, preincubada con ML334, se inyectó sobre la superficie del péptido Nrf2 inmovilizada. El ensayo se realizó a 25℃ con un caudal de 50 μL/min, lo que permite un tiempo de asociación de 1 minuto y un tiempo de disociación de 3 minutos. La superficie del chip del sensor se regeneró con 1M de NaCl a un caudal de 100 μL/min durante 1 minuto, seguido de dos lavados consecutivos de 1 minutos con el tampón en funcionamiento al mismo caudal. Se registró la señal de unión de Keap1 a Nrf2. La concentración de Keap1 sin límite se calculó utilizando su curva estándar, y la fracción de Keap1 en límite se trazó contra la concentración de los compuestos.

Forma de dosificación

Áreas de aplicación

En un ensayo de resonancia plasmona de superficie competitiva (SPR), ML334 se une a Keap1 con un Kd de 1 μM.
