The invention concerns amide derivatives of Formula (I), wherein: G is N or CH; R1 is a group such as hydroxy, halo, trifluoromethyl, C1-6alkyl and C1-6alkoxy; each of R2 and R3 is hydrogen, halo, C1-6alkyl, C2-6alkenyl or C2-6alkynyl; R4 is a group such as hydrogen, hydroxy, C1-6alkyl, C1-6alkoxy and C3-7cycloalkyl, or R4 is of the Formula (IC): —K—J, wherein J is aryl, heteroaryl or heterocyclyl and K is a bond or a group such as oxy and imino, R5 is a group such as hydrogen, halo and trifluoromethyl: m is 1-3 and q is 0-4; or pharmaceutically acceptable salts or in vivo cleavable esters thereof; processes for their preparation, pharmaceutical compositions containing them and their use in the treatment of diseases or medical conditions mediated by cytokines.

methods for their preparation mainly rely on thermal [3 + 2] cycloaddition of potentially dangerous acetylene and azides. Here we report a base-mediated [4 + 1] annulation of azoalkenes generated in situ from readily available difluoroacetaldehyde N-tosylhydrazones (DFHZ-Ts) with amines under relatively mild conditions. This azide- and acetylene-free strategy provides facile access to diverse 1-substituted

produced the most potentinhibitors of Flt and KDR tyrosine kinases activity with IC(50) values in the nanomolar range (e.g. 10, 12, 13, 16, and 18). Investigation of the quinazoline C-6 and C-7 positions indicates that a large range of substituents are tolerated at C-7, whereas variation at the C-6 is more restricted. At C-7, neutral, basic, and heteroaromatic side chains led to very potent compounds, as
Design, Synthesis, and Evaluation of Orally Active 4-(2,4-Difluoro-5-(methoxycarbamoyl)phenylamino)pyrrolo[2,1-<i>f</i>][1,2,4]triazines as Dual Vascular Endothelial Growth Factor Receptor-2 and Fibroblast Growth Factor Receptor-1 Inhibitors

A series of substituted 4-(2,4-difluoro-5-(methoxycarbamoyl)phenylamino)pyrrolo[2,1-f][1,2,4]triazines was identified as potent and selective inhibitors of the tyrosine kinase activity of the growth factor receptors VEGFR-2 (Flk-1, KDR) and FGFR-1. The enzyme kinetics associated with the VEGFR-2 inhibition of compound 50 (K(i) = 52 +/- 3 nM) confirmed that the pyrrolo[2,1-f][1,2,4]triazine analogues
