生物活性

Digitoxin is an effective Na+/K+-ATPase inhibitor, the EC50 value of Digitoxin is 0.78 μM. IC50 value: 0.78 μM (EC50) Target: Na+/K+-ATPase in vitro: Digitoxin shows a significantly cytotoxic effect in H1975 cells by causing G2 phase arrest, also remarkably activates 5′ adenosine monophosphate-activated protein kinase (AMPK). Moreover, Digitoxin suppresses microtubule formation through decreasing α-tubulin. Digitoxin effectively depresses the growth of TKI-resistance NSCLC H1975 cells by inhibiting microtubule polymerization and inducing cell cycle arrest. Digitoxin has the highest cytotoxicity in H1975 cells, whose CC50 value was 0.19 ± 0.06 μM. Digitoxin-induced inhibition mechanism is likely due to causing G2/M cell cycle arrest in H1975 cells in dose dependent manners.
