Mecanismo de acción (Mechanism of Action)

Características	A chemical probe inhibitor of Stat3 activity.
Targets/IC₅₀/Ki	STAT3 (Cell-free assay) 86 μM
In vitro	NSC 74859 (S3I-201) inhibits growth and induces apoptosis preferentially in tumor cells that contain persistently activated Stat3 by inhibiting Stat3·Stat3 complex formation and Stat3 DNA-binding and transcriptional activities. Moreover, it also inhibits the expression of the Stat3-regulated genes encoding cyclin D1, Bcl-xL, and survivin.This compound inhibits breast carcinoma MDA-MB-435, MDA-MB-453 and MDA-MB-231 cell lines with IC50 of 100 μM. In addition, the cells with impaired TGF-β signaling are four times as sensitive to S3I-201.A recent study shows that it potentiates the antiproliferative effect in HepG2 and Huh-7 cells via the STAT3 signalling pathway.
Ensayo de quinasa	Ensayo de unión de STAT3 al ADN in vitro y análisis EMSA
Ensayo de quinasa	Brevemente, se añaden 100 µL de biotinil-e-Ac-EPQpYEEIEL-OH (en 50 mM Tris/150 mM NaCl, pH 7,5) a cada pocillo de placas de microtitulación de 96 pocillos recubiertas de estreptavidina y se incuban con agitación a 4 °C durante la noche. Luego, las placas se enjuagan con PBS/Tween 20 y luego dos veces con 200 µL de BSA-T-PBS (0,2 % BSA/0,1 % Tween 20/PBS). Luego se añaden 50 µL de proteína de fusión Lck-SH2-GST (6,4 ng/ml en BSA-T-PBS) a cada pocillo de la placa de 96 pocillos en presencia y ausencia de 50 µL de NSC 74859 (S3I-201) (para concentraciones finales de 30 y 100 mM), y la placa se agita a temperatura ambiente durante 4 horas. Después de retirar las soluciones, cada pocillo se enjuaga cuatro veces con BSA-T-PBS (200 µL), y se añaden 100 µL de anticuerpo policlonal de conejo anti-GST (100 ng/mL en BSA-T-PBS) a cada pocillo y se incuba a 4 °C durante la noche. Después de lavar con BSA-T-PBS, se añaden 100 µL de anticuerpo de ratón anti-conejo conjugado con peroxidasa de rábano picante (200 ng/mL en BSA-T-PBS) a cada pocillo y se incuban durante 45 minutos a temperatura ambiente. Después de cuatro pasos de lavado con BSA-T-PBS y tres pasos de lavado con PBS-T, se añaden 100 µL de sustrato de peroxidasa a cada pocillo y se incuban durante 5-15 minutos. La reacción de peroxidasa se detiene añadiendo 100 µL de solución de ácido sulfúrico 1 M, y la absorbancia se lee a 450 nm con un lector de placas ELISA.
In vivo	NSC 74859 (S3I-201) (5 mg/kg, i.v. every 2 or every 3 days) shows the antitumor efficacy in mouse models with human breast tumor xenografts that harbor constitutively active Stat3.This compound treatment reduces Varicella-zoster virus (VZV) replication on the basis of the bioluminescence signal and the number of positive skin xenografts compared with DMSO-treated mice by inhibiting STAT3 phosphorylation.
