CD73-IN-5（Cat No.:I045148）is a potent, selective, non-nucleotide small-molecule inhibitor of CD73 (ecto-5′-nucleotidase) with an IC₅₀ of ~19 nM against human CD73. In CHO cells expressing human CD73, it shows strong cellular activity (IC₅₀ ~12.4 nM), effectively blocking AMP-to-adenosine conversion. By targeting CD73, it modulates adenosinergic signaling, making it valuable in cancer immunology and anti-tumor research. CD73-IN-5 has ~98% purity and is stable for 2 years at –20 °C (powder) or 6 months at –80 °C (solution). It is primarily used as a research tool in studies of immune regulation and tumor microenvironment.
