In Vitro: AZD0424 (1-5 μM; 24-48 hours) is emerged to be the more effective of the three tested inhibitors (AZM559756, AZD0530 and AZD0424), inducing the highest levels of apoptosis with the lowest concentrations in lymphoma cells.AZD0424 (5 μM; 48 hours) leads to increased G0/G1 cell cycle arrest in DOHH-2 and WSU-NHL cells, whereas the cell cycle progression of the nonsensitive cell lines Raji and Jurkat remains unaffected.
