  • Objective  To study the proliferation-inhibitng and apoptosis-inducing effect s of 23-hydroxy betulinic acid ( 23-HBA ) on human microcapillary endothelial cells ( HMEC) . Methods  The effect of 23-HBA on in vitro proliferation of HMEC was examined by SRB assay. The effect of 23-HBA on the cell cycle and apoptosis were analyzed by flow cytometry. Results  The proliferation of HMEC was inhibited significantly by 23-HBA with IC50 being 40. 44μg/ ml. Apoptosis peak was also shown by flow cytometry. The percentage of cell apoptosis increased with the increase of the drug concent ration, and the increase rate was significantly higher than that of the control cell group. The content of cells increased in Sphase and decreased in G2 / M phase. Conclusion  23-HBA can inhibit HMEC proliferation and induce apoptosis, could be developed as an antiangiogenic drug.
