promising activity (IC50 = 0.636–5.76 μM). Molecular docking studies guidance was used to improve the binding affinity for series 4a–j towards VEGFR-2 active site. This improvement was achieved by increasing the hydrophobic interaction with the hydrophobic back pocket of the VEGFR-2 active site lined with the hydrophobic side chains of Ile888, Leu889, Ile892, Val898, Val899, Leu1019 and Ile1044.

The present invention relates to sulphonamide derivatives, whith a urea moiety. The invention also relates to the use of the derivatives as inhibitors of collagen receptor integrins, especially α2β1 integrin inhibitors e.g. in connection with diseases and medical conditions that involve the action of cells and platelets expressing collagen receptors, their use as a medicament, e.g. for the treatment of thrombosis, inflammation, cancer and vascular diseases, pharmaceutical compositions containing them and a process for preparing them. The sulphonamide derivatives have the general formula (I) or (I′).

Discovery of N-phenyl-(2,4-dihydroxypyrimidine-5-sulfonamido) phenylurea-based thymidylate synthase (TS) inhibitor as a novel multi-effects antitumor drugs with minimal toxicity
cell migration and angiogenesis in cancer tissues. Furthermore, in vivo pharmacology evaluations of L14e showed significant antitumor activity in A549 cells xenografts with minimal toxicity. All of these results demonstrated that the L14e has the potential for drugdiscovery as a multi-effects inhibitor and provides a new reference for clinical treatment of non-small cell lung cancer.
