Bioactivity Comments
In addition to Bcr-Abl, flumatinib significantly inhibits the receptor tyrosine kinases, platelet-derived growth factor receptor (PDGFR) and mast/stem cell growth factor receptor (SCFR; c-Kit). Flumatinib inhibits the proliferation of tumour cells in which these kinases are overexpressed, and overcomes acquired imatinib resistance conferred by Bcr-Abl mutations in cellular assays and in in vivo tumour models [1]. Imatinib resistance observed in gastrointestinal stromal tumours (GISTs) harbouring secondary mutations in the KIT activation loop (e.g. D820G, N822K, Y823D, and A829P) can be overcome by flumatinib [2].
