A series of new ureidoindolin-2-one derivatives were synthesized and evaluated as inhibitors of receptor tyrosine kinases. Investigation of structure-activity relationships at positions 5, 6, and 7 of the oxindole skeleton led to the identification of 6-ureido-substituted 3-pyrrolemethylidene-2-oxindole derivatives that potently inhibited both the vascular endothelial growth factor receptor (VEGFR) and platelet-derived growth factor receptor (PDGFR) families of receptor tyrosine kinases. Several derivatives showed potency against the PDGFR inhibiting both its enzymatic and cellular functions in the single-digit nanomolar range. Among them, compound 35 was a potent inhibitor against tyrosine kinases, including VEGFR and PDGFR families, as well as Aurora kinases. Inhibitor 36 (non-substituted on the pyrrole or phenyl ring) had a moderate pharmacokinetic profile and completely inhibited tumor growth initiated with the myeloid leukemia cell line, MV4-11, in a subcutaneous xenograft model in BALB/c nude mice.
