Based on the structure-activity relationships of RGD-containing peptides, a series of 1,3-dihydro-1,3-dioxo-2H-isoindole derivatives were synthesized. All of them were first reported. Their structures were confirmed by spectral data and elemental analysis. Their ability to inhibit angiogenesis were evaluated in the chick embryo chorioallantoic membrane assay at 10-5 mol/L. Compounds 5b and 5e displayed obviously antiangiogenic activity.
