A novel class of furo[2,3-d]pyrimidines has been discovered as potent dual inhibitors of TIE-2 and VEGFR2 Receptor Tyrosine Kinases (TK) and a diarylurea moiety at 5-position shows remarkably enhanced activity against both Enzymes. One of the most active compounds, 4-amino-3-(4-((2-fluoro-5-(trifluoromethyl)phenyl)amino-carbonylamino)phenyl)-2-(4-methoxyphenyl)furo[2,3-d]pyrimidine (7k) is <3 nM on both TK receptors and the activity is rationalized based on the X-ray crystal structure.
