ABT-510 TFA is a synthetic peptide made up of nine amino acids that mimics the anti-angiogenic activity of the endogenous protein thrombospondin-1 (TSP-1), a TSP-1 mimetic drug. It is available as the trifluoroacetic acid (TFA) salt form of ABT-510. Pro-angiogenic growth factors such as vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), hepatocyte growth factor (HGF), and interleukin 8 (IL-8) are inhibited by ABT-510. These pro-angiogenic growth factors are crucial for tumor neovascularization. In a phase 1 clinical trial with newly diagnosed glioblastoma, the TSR-based drug ABT-510 demonstrated anti-angiogenic properties.
| ln Vitro |
In the human epithelial cancer cell lines SKOV3, OVCAR3, and CAOV3, ABT-510 (1, 5, 10, 20, and 50 nM; 24 hours) induces ID 8 cell carcinoma and (50 nM, 24 hours) increases the incidence of liver cancer [ABT-510 (0-10 μM; 7 days) inhibits the growth and height of NO-stimulated vascular cells into the extracellular matrix]. ABT-510 has the ability to suppress both NO-driven cGMP background and tumor-driven vascular cell proliferation [3].

|---|---|
| ln Vivo |
ABT-510 (100 mg/kg; intraperitoneal injection; once daily for 90 days) dramatically decreases the size, volume, and spread of secondary tumors in mice as well as cellular luminescence in vivo [1]. In models of inflammatory bowel illness, -510 (60 mg/kg; subcutaneous minipump; once daily for 7 days) decreases angiogenesis and inflammation [2].

| Animal Protocol |
Animal/Disease Models: TSP-1-Null mice (C57BL/6 background; orthotopic, syngeneic model of epithelial ovarian cancer) [1].
Doses: 100 mg/kg Route of Administration: intraperitoneal (ip) injection; one time/day for 90 days Experimental Results: diminished ovarian tumor growth in wild-type and TSP-1 null mice. The amount of ascites is Dramatically diminished and the formation of peritoneal lesions is completely eliminated. Reversal of ovarian tumor hypervascularization and increased proportion of mature vessels. Animal/Disease Models: TSP-1-Null mice (C57BL/6 background; 6 weeks old; DSS-induced inflammatory bowel disease mouse model) [2]. Doses: 60 mg/kg Route of Administration: subcutaneously (sc) (sc) implanted osmotic minipump (0.5 μL/h); one time/day for 7 days Experimental Results: Dramatically delayed DSS-induced bleeding and improved overall disease severity. Inflammation grade and angiogenesis were Dramatically diminished |
