Description Contents hide 1 Product Description 2 Product Specifications 3 Mechanism of Action & Research Applications 4 Side Effects 5 Disclaimer 6 Keywords Product DescriptionABT-510 is a synthetic peptide designed as a potent analogue of thrombospondin-1 (TSP-1), a multifunctional glycoprotein that naturally regulates cell-to-cell and cell-to-matrix interactions. Thrombospondin-1 plays an important role in angiogenesis, the process of new blood vessel formation, which is essential in both physiological and pathological conditions. ABT-510 captures the anti-angiogenic properties of thrombospondin-1 in a stable, biologically active peptide form, making it a highly valuable research compound.Angiogenesis is a central mechanism underlying tumor growth and metastasis, as solid tumors require blood supply for continued proliferation. By mimicking thrombospondin-1 activity, ABT-510 blocks angiogenesis pathways, effectively starving tumors of nutrients and oxygen. Preclinical research has shown that ABT-510 induces apoptosis in tumor cells, reduces vascular density in tumors, and inhibits progression in animal models of epithelial ovarian cancer.One of the key research advantages of ABT-510 is its dual role in both oncology research and inflammatory disease models. In cancer studies, ABT-510 reduces tumor angiogenesis, induces programmed cell death, and modulates tumor microenvironment interactions. In inflammatory bowel disease models, ABT-510 attenuates inflammation, reduces vascular infiltration, and suppresses immune-mediated tissue damage. These multifaceted effects make ABT-510 an important tool for understanding angiogenesis and apoptosis pathways in both cancer and chronic inflammation.Structurally, ABT-510 is a 26-amino acid peptide engineered for stability and enhanced activity compared to the native thrombospondin protein fragment. Its design incorporates modifications that improve resistance to enzymatic degradation and extend its half-life in biological systems. This stability allows for more reproducible results in both in vitro and in vivo research.Research applications of ABT-510 extend beyond ovarian cancer and IBD. It has been tested in preclinical models of melanoma, prostate cancer, and breast cancer, where angiogenesis plays a key role in tumor progression. Additionally, its ability to regulate vascular and immune responses makes it a candidate research tool in autoimmune disorders and wound healing studies.ABT-510’s consistent anti-angiogenic activity makes it an excellent reference compound for evaluating new therapeutic peptides and small molecules targeting the angiogenesis pathway. It is frequently used in mechanistic studies to dissect signaling pathways involving CD36 and other receptors implicated in thrombospondin-mediated responses.In summary, ABT-510 represents an important peptide research compound. As an optimized TSP-1 analogue, it enables scientists to investigate anti-angiogenic, pro-apoptotic, and anti-inflammatory mechanisms across multiple disease models. Its stability, reproducibility, and well-documented biological activities make it a cornerstone peptide in angiogenesis and cancer biology research.Product SpecificationsParameterDetailsProduct NameABT-510CAS Number251579-55-2SynonymsTSP-1 analogue peptide, Thrombospondin mimetic peptideMolecular FormulaC___H___N___O___ (exact formula available upon request)Molecular WeightAvailable upon requestAppearanceWhite to off-white lyophilized peptide powderPurity≥95% (HPLC confirmed)Peptide Length26 amino acidsFormulationSynthetic peptideSolubilitySoluble in water, PBS, and DMSOStorage-20°C (long-term, lyophilized)StabilityStable for up to 24 months lyophilized; 2–3 weeks in solution at 4°CTarget ReceptorsCD36 receptor, angiogenesis-related pathwaysActivityAnti-angiogenic, pro-apoptotic, anti-inflammatoryApplicationsCancer biology, angiogenesis studies, inflammatory disease researchSafetyFor laboratory research use only; not for human or veterinary applicationDetailed Specifications AnalysisMolecular Structure: As a 26-residue peptide, ABT-510 includes modifications for stability and activity enhancement.Purity & Quality Control: High-performance liquid chromatography (HPLC) ensures ≥95% purity, crucial for reliable reproducibility in experiments.Storage & Handling: Lyophilized form ensures peptide integrity; aqueous reconstitution allows flexibility in assays.Experimental Use: Appropriate for both in vitro cell culture assays and in vivo animal studies.Receptor Targets: CD36 binding is central to ABT-510’s mechanism, disrupting endothelial cell survival signaling and triggering apoptosis.Mechanism of Action & Research ApplicationsMechanism of ActionABT-510 primarily acts through the CD36 receptor, a known mediator of thrombospondin-1 activity on endothelial cells. By binding to CD36, ABT-510 inhibits endothelial cell proliferation and migration, two essential steps in angiogenesis. This blockade promotes apoptosis in endothelial cells, resulting in reduced blood vessel formation in tumor tissues.Anti-Angiogenic Action: Prevents neovascularization by suppressing VEGF (vascular endothelial growth factor) pathways and disrupting endothelial survival signals.Pro-Apoptotic Effect: Directly induces apoptosis in tumor-associated endothelial cells and tumor cells.Immunomodulatory Role: Reduces inflammatory cytokine release, immune cell infiltration, and tissue damage in inflammatory bowel disease models.Tumor Microenvironment Modulation: Alters interactions between tumor cells, stroma, and vascular structures, leading to impaired tumor growth and metastasis.Research ApplicationsCancer ResearchEpithelial Ovarian Cancer: ABT-510 is widely studied in ovarian cancer models, where it suppresses angiogenesis and tumor progression.Melanoma & Prostate Cancer: Preclinical studies demonstrate anti-tumor activity through endothelial cell apoptosis and microvessel reduction.Combination Therapy Models: Often studied alongside chemotherapy or targeted agents to assess synergistic anti-angiogenic effects.Inflammatory Bowel Disease (IBD)In murine models, ABT-510 reduces vascular permeability, immune infiltration, and inflammatory damage.Provides insight into the role of angiogenesis in chronic inflammation.Autoimmune & Inflammatory DisordersPotential relevance in conditions where aberrant angiogenesis contributes to pathology (e.g., rheumatoid arthritis).Vascular Biology & Endothelial StudiesServes as a reference compound for dissecting CD36-mediated pathways.Useful for testing novel anti-angiogenic therapeutics in comparative assays.Pharmacology & Toxicology StudiesProvides a model peptide to study the pharmacokinetics and pharmacodynamics of angiogenesis inhibitors.ABT-510’s broad range of applications underscores its role as a versatile experimental peptide. By bridging oncology and inflammatory biology, it supports diverse lines of biomedical investigation.Side EffectsIn preclinical studies, ABT-510 is generally well tolerated in animal models. However, as with any biologically active peptide, potential side effects must be considered in research contexts.Observed or Potential Side Effects in Research ModelsLocal Reactions: Possible irritation or mild inflammation at injection sites.Vascular Effects: Over-suppression of angiogenesis could impair wound healing or normal tissue repair.Systemic Effects: High doses may cause fatigue, weight loss, or reduced activity in animal models.Immune Modulation: Altered immune cell function due to reduced angiogenesis in inflamed tissues.Metabolic Changes: Some evidence suggests shifts in glucose and lipid metabolism under chronic dosing.Experimental ConsiderationsDose Optimization: Proper titration is essential to avoid excessive suppression of physiological angiogenesis.Model-Specific Responses: Effects may vary depending on tumor type, inflammation model, or animal strain.Long-Term Exposure: Prolonged angiogenesis inhibition may interfere with tissue regeneration studies.Combination Studies: When used alongside chemotherapy or immunotherapy, careful monitoring of synergistic toxicity is advised.Overall, ABT-510 demonstrates a favorable safety profile in preclinical studies, but it must be handled with care to avoid unintended experimental confounders.DisclaimerFor laboratory research use only.
