CD73-IN-5 is a highly potent and selective small molecule inhibitor of CD73, demonstrating non-nucleotide characteristics. It exerts its inhibitory effects with a remarkable IC50 value of 19 nM.

MethADP (Adenosine 5'-(α,β-methylene)diphosphate) is a specific CD73 inhibitor that inhibits the enzyme ecto-5′-nucleotidase (ecto), which has been used in the study of neurological and cardiovascular diseases.

Adenosine 5’-methylenediphosphate is an inhibitor of ecto-5’-nucleotidase, also known as CD73, with a Kivalue of 37 nM.1It inhibits cAMP accumulation induced by adenosine 5’-monophosphate , adenosine 5’-diphosphate , or adenosine 5’-triphosphate but not adenosine in VA-13 human fibroblasts when used at a concentration of 100 μM. Adenosine 5’-methylenediphosphate reduces proliferation of U138MG glioma cells, as well as inhibits the invasion and migration of MHCC97H hepatocellular carcinoma (HCC) cells in a migration assay.2,3It increases tumor infiltration of CD3+CD8+T cells and reduces tumor growth in a K1735 murine melanoma model when administered at a dose of 400 μg/mouse.4 1.Bruns, R.F.Adenosine receptor activation by adenine nucleotides requires conversion of the nucleotides to adenosineNaunyn Schmiedebergs Arch.

CD73-IN-8, a potent CD73 inhibitor, prevents the catalytic activity of CD73, an enzyme responsible for converting extracellular 5'-phosphate adenosine (5'-AMP) to adenosine. Adenosine, once produced, can induce immunosuppressive effects and facilitate tumor proliferation and/or metastasis. Therefore, CD73-IN-8 holds promise in the development of therapeutic interventions for tumor-related diseases[1].

CD73-IN-7 is a potent CD73 inhibitor that can be used for preparing a medicament for tumor-related diseases. CD73 can catalyze the production of adenosine from extracellular 5'-phosphate adenosine (5'-AMP) which can induce immunosuppressive effects and promote tumor proliferation and/or metastasis [1].

PSB-12379 disodium is a nucleotide analogue acting as a potent inhibitor of Ecto-5'-Nucleotidase (CD73), demonstrating inhibitory constants (Ki) of 9.03 nM in rats and 2.21 nM in humans [1] [2].

CD73-IN-11 is able to used for tumor-related diseases medicament preparing. CD73-IN-11 is an effective CD73 inhibitor. CD73 can catalyze the production of adenosine from extracellular 5'-phosphate adenosine (5'-AMP) which induce immunosuppression and promote tumor proliferation and/or metastasis [1].

CD73-IN-9 is a potent CD73 inhibitor that be used in preparing the tumor-related diseases medicament. CD73 can catalyze the adenosine production from extracellular 5'-phosphate adenosine (5'-AMP). The adenosine can induce immunosuppressive effects and promote tumor proliferation and/or metastasis [1].

CD73-IN-10 can be used in preparing tumor-related diseases medicament. CD73-IN-10 is a potent CD73 inhibitor that can catalyze the adenosine production from extracellular 5'-phosphate adenosine (5'-AMP). Adenosine induces immunosuppression and can promote tumor proliferation and/or metastasis [1].
