- W607012984 abstract "As bioisosteres of quinazolinones and benzofuranes respectively, thienopyrimidinones and thienofuranes can be envisioned as promising precursors for the design of potential bioactive compounds, especially anti-angiogenic molecules. Tumoral angiogenesis plays an important role in the tumor growth and metastasis of cancer. Therefore, one of the most studied anti-cancer strategies implies the design of small kinase inhibitors, targeting more specifically VEGFR-2 (Vascular Endothelial Growth Factor Receptor 2), which is considered as key component in the angiogenic process. In this context, our work has essentially focused on the synthesis of new series of thienopyrimidinone and thienofuran derivatives with potential inhibitory activity of VEGFR-2. For each of the designed structures, we have first studied, by 3D-QSAR, the influence of various modulations of the heterocyclic core (including substitution and isomery of the core, nature of the extending chain) on the predicted activity. Then, we have elaborated several synthetic pathways allowing access to the targeted compounds. Selective synthesis of a choosen thienofuran isomer has been performed through a chemoselective methodology starting from wisely functionalized 3-O-alkylated thiophenes. These molecules could be then further functionalized to access to final compounds. Simultaneously, synthesis of thieno[2,3-d]pyrimidinone derivatives has been carried out according to two strategies : a convergent pathway allowed a direct introduction of some of the envisioned modulations on the central core in nitrogen series (linking heteroatom), while a linear pathway has ensured the desired modulations on oxygen and sulfur series" @default.
