AZD4547 profoundly and synergistically enhanced the anti‐proliferative effect of BI2536 in KRAS‐mutant lung and pancreatic cancer cells, although AZD4547 (5 μM) and BI2536 (5 nM) alone at the tested dosage only mildly to moderately affected cell growth (Fig 2A and B). The gene discussed is KRAS; the disease is familial pancreatic carcinoma.
