Flumatinib is a secondary carboxamide resulting from the formal condensation of the carboxy group of 4-[(4-methylpiperazin-1-yl)methyl]-3-(trifluoromethyl)benzoic acid with the amino group of 2-methyl-N3-[4-(pyridin-3-yl)pyrimidin-2-yl]pyridine-3,5-diamine. It is an inhibitor of the non-receptor tyrosine kinase Bcr-Abl (IC50 = 1.2 nM) and has been approved in China for the treatment of chronic myeloid leukaemia. It has a role as an antineoplastic agent, an apoptosis inducer and an EC 2.7.10.2 (non-specific protein-tyrosine kinase) inhibitor. It is a secondary carboxamide, a member of benzamides, an aminopyridine, an aminopyrimidine, a N-methylpiperazine, a secondary amino compound and a member of (trifluoromethyl)benzenes.
