Description of DDD85646

DDD85646 es un potente inhibidor de la Trypanosoma brucei N-myristoyltransferase (NMT), con valores de concentración inhibitoria media (IC₅₀) de 2nM frente a la T. brucei NMT (TbNMT) y de 4nM frente a la NMT humana (hNMT) [1]. DDD85646 inhibe la proliferación de trypanosomes[2], y también presenta actividad antiviral al suprimir la replicación viral[3-4].

In vitro, el tratamiento conjunto de células de leucemia monítica aguda THP-1 con DDD85646 (10μM) y el inductor de ferroptosis Erastin (10μM) durante 36 horas aumentó la susceptibilidad a la derroptosis —carazterizada por la peroxidación lipídica, agotamiento de glutación y reducción mitocondrial —mediante la inhibición de lka localización de la FSP1 en la membrana celular[5]. El pretratamiento de células A549, HEK293T, HAP1 y Vero E6 con DDD85646 (0.1–10μM) durante 1–5 horas, seguido de la infección con el virus de la meningitis linfocítica coroidea (LCMV; MOI=0.05–1) durante 24–72 horas, suprimió de forma la expresión de proteínas virales, redujo los títulos virales y disminuyó el número de células infectadas[6].

In vivo, la administración oral de DDD85646 (12.5–50mg/kg) dos veces al día durante 4 días a ratones infectados con cepas S427 o STIB900 de Trypanosoma brucei provocó una eliminación de parásitos en la sangre periférica[7]. La inyección subcutánea de DDD85646 (20–60mg/kg) una vez al día o cada dos días durante 7–16 días en ratones con xenoinjertos de linfoma DOHH2 o BL2 indujo una inhibición notable del desarrollo tumroal y la regresión tumoral completa[8].

Protocol of DDD85646

Experimentos celulares [1]:

Líneas celulares

Células THP-1 (línea celular de leucemia monocítica aguda humana)

Método de preparación

Las células THP-1 se cultivaron en un medio RPMI-1640 suplementado con 10% de suero bovino fetal (FBS), 2mM de L-glutamine y 1% de penicillin-streptomycin a 37°C, 5% de CO₂. Las células se trataron con el inductor de ferroptosis Erastin (10μM) y/o DDD85646 (10μM) durante 36 horas.

Condiciones de reacción

10μM; 36h

Áreas de aplicación

El tratamiento conjunto con DDD85646 y Erastin aumentó la susceptibilidad a la ferroptosis en las célulass THP-1, caracterizada por una peroxidación elevada de lípidos (aumento de los niveles de MDA y 4-HNE), glutathione (GSH) depletion y la contracción mitocondrial observada a través de la microscopía electrónica.
Experimentos con animales [2]:

Modelos animales

Ratones hembras de NMRI infectados con Trypanosoma brucei brucei S427

Método de preparación

Los ratones fueron infectados intraperitonealmente con trypomastigotes. Para el modleo (T. b. brucei S427), los ratones infectados fueron tratados por vía oral (por gavage) con DDD85646 a una dosis de 12.5mg/kg o 50mg/kg dos veces al día durante 4 días.

Forma de dosificación

12.5-50mg/kg; p.o.; dos veces al día durante 4 días.

Áreas de aplicación

DDD85646 demostró una potente eficacia en el modelo de ratón, logrando una curación completa a 12.5mg/kg durante 4 días contra T. b. brucei S427 y a 50mg/kg durante 4 días contra T. b. rhodesiense STIB900.
