OP-5244 is a potent and orally active inhibitor of CD73, with an IC50 of 0.25 nM. OP-5244 reverses immunosuppression through blocking of adenosine production, and has the potential for the cancer research[1].
OP-5244 inhibits the production of adenosine (ADO), with an EC50 of 0.79±0.38 nM in H1568 (NSCLC) cells[1].OP-5244 inhibits AMP hydrolysis to ADO in peripheral blood derived CD8+ T cells with an EC50 of 0.22 nM[1].OP-5244 (4.1-1000 nM; 96 h) rescues AMP-suppressed CD8+ T cells proliferation and cytokine production[1].OP-5244 (0.01 nM-10 μM) inhibits ADO production completely in human and murine cancer cell lines (H1568 and EMT6, respectively)[1].
OP-5244 (15 mg/kg/day; s.c. for 13 d) exhibits anti-tumor effects as a single agent as shown by the tumor growth inhibition in mice[1].OP-5244 (150 mg/kg; p.o. twice daily for 16 d) increases CD8+ T cells infiltration and reverses immunosuppression in mice[1].OP-5244 (0.2 mg/kg; i.v.) exhibits terminal elimination half-lives (rat 8.5, dog 0.82, cyno 4.6 h) due to moderate plasma clearance (rat 0.18, dog 1.22, cyno 0.05 L/kg/h) and low steady-state volume of distribution (rat 0.22, dog 0.29, cyno 0.10 L/kg/h)[1].OP-5244 (10 mg/kg; p.o.) exhibits Cmax (rat 0.82, dog 1.25, cyno 1.72 μM) and AUC (rat 1.96, dog 1.75, cyno 14.2 µM•h) [1].

Orally Bioavailable Small-Molecule CD73 Inhibitor (OP-5244) Reverses Immunosuppression through Blockade of Adenosine Production
J Med Chem 2020 Sep 24;63(18):10433-10459.PMID:32865411DOI:10.1021/acs.jmedchem.0c01086
The adenosinergic pathway represents an attractive new therapeutic approach in cancer immunotherapy. In this pathway, ecto-5-nucleotidase CD73 has the unique function of regulating production of immunosuppressive adenosine (ADO) through the hydrolysis of AMP. CD73 is overexpressed in many cancers, resulting in elevated levels of ADO that correspond to poor patient prognosis. Therefore, reducing the level of ADO via inhibition of CD73 is a potential strategy for treating cancers. Based on the binding mode of adenosine 5'-(α,β-methylene)diphosphate (AOPCP) with human CD73, we designed a series of novel monophosphonate small-molecule CD73 inhibitors. Among them, OP-5244 (35) proved to be a highly potent and orally bioavailable CD73 inhibitor. In preclinical studies, 35 completely inhibited ADO production in both human cancer cells and CD8+ T cells. Furthermore, 35 lowered the ratio of ADO/AMP significantly and reversed immunosuppression in mouse models, indicating its potential as an in vivo tool compound for further development.
