MAZ51

MAZ51 is a VEGFR-3 (Flt-4) tyrosine kinase inhibitor. MAZ51 is able to block the proliferation of VEGFR-3-expressing human endothelial cells and is less potently able to induce their apoptosis. MAZ51 also inhibits the proliferation and induces the apoptosis of a variety of non-VEGFR-3-expressing tumor cell lines.In vivo, MAZ51 significantly inhibits the growth of rat mammary carcinomas. These data establish MAZ51 as a compound with antitumor properties that inhibits tumor growth directly and also indirectly by interfering with tumor-host interactions.
