ABT-510 acetate

ABT-510 acetate is an anti-angiogenic TSP peptide (Thrombospondin-1 analogue) that induces apoptosis and inhibits ovarian tumour growth in an orthotopic, syngeneic model of epithelial ovarian cancer. ABT-510 acetate also reduces angiogenesis and inflammatory responses in a murine model of inflammatory bowel disease. ABT-510 acetate can be used in studies of cancer (particularly epithelial ovarian cancer) and inflammatory bowel disease (IBD).

ABT-510 acetate (1, 5, 10, 20, 50 nM; 24 h) induces apoptosis in ID8 cells and increases the incidence of apoptosis in the human epithelial cancer cell lines SKOV3, OVCAR3, and CAOV3^[1].
ABT-510 acetate (0-10 μM; 7 days) inhibits NO-stimulated vascular cell outgrowth into and invasion through extracellular matrix. ABT-510 acetate blocks tumor-driven vascular cell outgrowth, NO-driven cGMP flux, and CD36-mediated fatty acid uptake. ^[3].

ABT-510 acetate (100 mg/kg; i.p.; single daily for 90 days) induces cells apoptosis in vivo and leads to a significant reduction in epithelial ovarian tumor size, ascites fluid volume, and secondary lesion dissemination in mice^[1].
ABT-510 acetate (60 mg/kg; osmotic minipumps for s.c.; single daily for 7 days) decreases angiogenesis and inflammation in a murine model of inflammatory bowel disease^[2].
