Methyl 3-[4-(3-arylureido)phenylamino]thieno[3,2-b]pyridine-2-carboxylates as potential inhibitors of VEGFR-2: synthesis and molecular modelling studies. IPB - Escola Superior Agrária
Peixoto, Daniela; Calhelha, Ricardo C.; Dias, Sofia; Froufe, Hugo J.C.; Abreu, Rui M.V.; Ferreira, Isabel C.F.R.; Queiroz, Maria João R.P..
When over expressed or mutated, protein tyrosine kinases become potent oncoproteins that cause deregulated cell growth angiogenesis and metastasis. Because of these characteristics, they are targets for small molecule inhibitors in the treatment of cancer. Recently some thieno[3,2-c]pyridine 1,3-diarylurea derivatives were prepared as VEGFR-2 (vascular endothelium growth factor receptor-2) inhibitors.1 Here we present the synthesis of methyl 3-[4-(3-arylureido)phenylamino]thieno[3,2-b]pyridine-2-carboxylates 2 in excellent yields, by reaction of the methyl 3-(4-aminophenylamino)thieno[3,2-b]pyridine-2-carboxylate 1, prepared also by us, with different arylisocyanates (Scheme).

Methyl 3-amino-6-[4 or 3 or 2-(3-arylureido)phenyl]thieno[3,2-b]pyridine-2-carboxylates: synthesis and molecular modelling studies using VEGFR-2. IPB - Escola Superior Agrária
Peixoto, Daniela; Dias, Sofia; Froufe, Hugo J.C.; Abreu, Rui M.V.; Ferreira, Isabel C.F.R.; Queiroz, Maria João R.P..
The membrane receptor tyrosine kinases (RTKs), possess both extracellular and intracellular domains and selectively catalyze the phosphorylation of tyrosine hydroxyl groups in response to binding of certain extracellular growth factors. RTK signalling pathways are normally highly regulated, yet their over-activation has been shown to promote the growth, survival, and metastasis of cancer cells, and has been associated with the progression of various human cancers. Recently some thieno[3,2-c]pyridine 1,3-diarylurea derivatives were prepared as VEGFR-2 (vascular endothelium growth factor receptor-2) inhibitors.1 Here we present the synthesis of methyl 3-amino-6-[4 or 3 or 2-(3-arylureido)phenyl]thieno[3,2-b]pyridine-2-carboxylates 2 by reaction of the methyl...
