    • The homology model of Tie2 was generated in the program MOE using the crystal structure FGFR-2 kinase (PDB code 1oec) as the structural template; compounds 1-3 were manually docked into the homology model based on the bound conformation of SB-203850 in crystal structure 1a9u. Figure 2 depicts the manual docking model for compound 1 in a second-generation homology model of an active form of Tie2; this second-generation homology model was generated in the program MOE using the crystal structures of inactive Tie2 (PDB code 1fvr) and active FGFR-2 kinase (PDB code 1oec) as structural templates. Figures were generated using the program pymol.
