It is a FGF/VEGF receptor tyrosine kinase inhibitor. It has a role as a fibroblast growth factor receptor antagonist, an antineoplastic agent and an EC 2.7.10.1 (receptor protein-tyrosine kinase) inhibitor. It is a pyridopyrimidine, a member of ureas, a tertiary amino compound, a dimethoxybenzene, an aromatic amine and a biaryl. It is functionally related to a PD-166866."}]
