The hydroxy group of fumagillol (3), a degradation product of fumagillin (1), was acylated, sulfonylated, alkylated or carbamoylated, and the anti-angiogenic activity of the resulting products was examined. These compounds inhibited the angiogenesis induced by basic fibroblast growth factor in the rat corneal micropocket assay and the growth of vascular endothelial cells in vitro. Among them, compound 2 (AGM-1470) was found to show the most potent inhibitory effect on the growth of vascular endothelial cells and was selected form this series as a candidate for further development.
烟曲霉素(1)的降解产物烟曲霉醇(3)的羟基被酰化、磺酰化、烷基化或氨基甲酰化,并考察了所得产物的抗血管生成活性。这些化合物抑制了在大鼠角膜微囊中由碱性成纤维细胞生长因子诱导的血管生成以及体外血管内皮细胞的生长。其中,化合物2(AGM-1470)被发现对血管内皮细胞生长具有最强的抑制作用,并被选为这一系列的候选药物进一步开发。
