    • Target Organs:

      VEGFR inhibitor TargetMol T2514
    • Chemical Class:

      A member of the class of phenylureas that is urea in which one of the nitrogens is substituted by a 2-fluoro-5-methylphenyl group, while the other is substituted by a <ital>p</ital>-(3-amino-1<element >H</element>-indazol-4-yl)phenyl group. It is a potent, selective inhibitor of vascular endothelial growth factor and platelet-derived growth factor receptor tyrosine kinases. ChEBI CHEBI:91435
