CD73-IN-4 is a potent and selective methylenephosphonic acid CD73 inhibitor, with an IC 50 of 2.6 nM for human CD73 . CD73-IN-4 is potential for the research of cancer immunology In Vitro CD73-IN-4 (compound 4a) exhibits excellent potency against soluble hCD73 (IC 50 = 0.86 nM) and soluble mouse CD73 (mCD73; IC 50 = 3.0 nM), CHO cells overexpressing hCD73 (IC 50 = 2.6 nM) or mCD73 (IC 50 = 13 nM), and the human ovary cancer cell line SKOV-3 (IC 50 = 0.55 nM). It exhibits excellent selectivity (IC 50 > 10 000 nM) against CD39, A2aR, and NTPDase2, 3, and 8. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
