RBN-2397 is a potent, accross species and orally active NAD⁺ competitive inhibitor of PARP7 (IC₅₀<3 nm). rbn-2397 selectively binds to parp7 (K_d=0.001 μM) and restores IFN signaling. RBN-2397 has the potential for the study of advanced or metastatic solid tumors^[1][2].

RBN-2397 (0.0001-100 μM; 24 hours) inhibits cells proliferation with an IC₅₀ value of 20 nM in NCI-H1373 lung cancer cells^[2].
RBN-2397 (0.4 nM-1 μM; 24 hours) shows a restoration of type I IFN response by an increase in STAT1 phosphorylation as a dose-dependent manner in NCI-H1373 human lung cancer cells^[2].
RBN-2397 (0.0001-1 μM; 24 hours) inhibits cell MARylation in a cell biochemial assay with an EC₅₀ value of 1 nM^[2].

RBN-2397 (oral administration; 3-100 mg/kg; once daily; 24-32 days) induces tumor-specific adaptive immune memory in CT26 syngeneic model with durable complete responses in CT26 tumor-bearing BALB/c mice^[2].
RBN-2397 (oral administration; 3-100 mg/kg; once daily; 32 days) causes complete regressions at the dose 100 mg/kg and exerts a dose-dependent effects on tumor growth at dose levels of ≥30 mg/kg^[2].
The half-life (t_1/2) of RBN-2397 in vivo is 325 mins^[2].
