Abstract The antiangiogenic effects of three novel anilinoquinazoline derivatives were studied with the aim to find new multi-kinase inhibitors as anticancer agents. The compounds are characterized by dioxolane, dioxane and dioxepine rings and bear the same aniline substituent in 4 position as vandetanib, known antiangiogenic agent. The in vitro assays were carried out on human umbilical vein endothelial cells (HUVECs), whereas in vivo angiogenesis was evaluated by means of Matrigel plug assay. The results showed that these compounds exert, even though to different extents, antiangiogenic activity affecting the various step of the process that leads to the formation of new blood vessels. At high concentrations they induced antiproliferative effects, whereas at non-cytotoxic concentrations they inhibited cell migration and the formation of tubular structures in Matrigel. In in vitro assays the dioxolane derivative 1 was more effective than vandetanib. Indeed, it inhibited the effects induced by exogenous VEGF and FGF-2 on both cell proliferation and morphogenesis, whereas vandetanib was completely ineffective. Moreover, all the compounds, as vandetanib, counteracted the FGF-2-induced increase in the hemoglobin content in the Matrigel plugs. Our results showed that all the three novel derivatives possess both in vitro and in vivo antiangiogenic activity, with compound 1 more effective than vandetanib to inhibit in vitro angiogenesis induced by exogenous cytokines.
