Hybrid angiogenesis inhibitors: Synthesis and biological evaluation of bifunctional compounds based on 1-deoxynojirimycin and aryl-1,2,3-triazoles

Synthesis of hybrids of 1-deoxynojirimycin (DNJ) and 5-aryl-1,2,3-triazole as potential bifunctional inhibitors of angiogenesis is described. The DNJ component inhibits the biosynthesis of cell surface oligosaccharides necessary for angiogenesis, whereas the aryl-1,2,3-triazole inhibits methionine aminopeptidase II, a target in angiogenesis therapy. One bifunctional compound was a more potent inhibitor of angiogenesis in vitro than DNJ alone or the 5-aryl-1,2,3-triazole alone.
