CD73 (Ecto-5′-nucleotidase) is a 70-kD glycosylphosphatidyl inositol (GPI)-anchored cell surface protein encoded by the NT5E gene that plays a crucial role in switching on adenosinergic signaling. CD73 is an ectonucleotidase which catalyzes the terminal step in extracellular adenine nucleotide breakdown: the conversion of AMP to adenosine. Adenosine, which binds to a discrete family of cell surface receptors to initiate intracellular signaling cascades, has been shown to be anti-inflammatory and vasorelaxant.

CD73 has both enzymatic and non-enzymatic functions in cells: as a nucleotidase, CD73 catalyzes the hydrolysis of AMP into adenosine and phosphate, and CD73-generated adenosine plays an important role in tumor immunoescape; moreover, CD73 also functions as a signal and adhesive molecule that can regulate cell interaction with extracellular matrix components, such as laminin and fibronectin, to mediate the invasive and metastatic properties of cancers. Both the enzymatic and non-enzymatic functions of CD73 are involved in cancer-associated processes and are not completely independent of each other. There is ample evidence to show that CD73 is a key regulatory molecule in cancer development and is overexpressed in many cancers, including leukemia, glioblastoma, melanoma, ovarian cancer, esophageal cancer, prostate cancer and breast cancer.

    8-BuS-AMP
    		Inhibitor 99.90%
    8-BuS-AMP is a NTPDase1 inhibitor and a CD73/CD39 inhibitor, with an IC50 of 35 μM and a Ki value of 0.292 μM against human NTPDase1; its Ki values against human CD73 and CD39 are 1.19 μM and 0.847 μM, respectively. 8-BuS-AMP binds to the substrate-binding pockets of NTPDase1 and CD73 to effectively block the conversion of ATP and AMP to adenosine, thereby enhancing the activation and proliferation of human peripheral T lymphocytes. 8-BuS-AMP possesses excellent enzymatic hydrolysis resistance and metabolic stability, resists hydrolysis by multiple NTPDase subtypes, and shows no activity against P2Y1 and P2Y12 receptors. 8-BuS-AMP can be used in purinergic signaling pathway and cancer-related studies.
