Oral ENPP1 inhibitor designed using generative AI as next generation STING modulator for solid tumors. (PubMed, Nat Commun) - "In murine syngeneic models across cancer types, ISM5939 synergizes with targeting the PD-1/PD-L1 axis and chemotherapy in suppressing tumor growth with good tolerance. Our findings provide evidence supporting ENPP1 as an innate immune checkpoint across solid tumors and reports an AI design-aided ENPP1 inhibitor, ISM5939, as a cutting-edge STING modulator for cancer therapy, paving a path for immunotherapy advancements."

ISM5939, a novel, potent, orally available, selective ENPP1 inhibitor enhances the anti-tumor effects of immune checkpoint inhibitors in syngeneic murine cancer models (SITC 2023) - "Conclusions ISM5939, is a novel, potent ENPP1 inhibitor that augments the effectiveness of anti-PD-L1 or anti-PD1 therapy in multiple syngeneic mouse tumor models, while exhibiting favorable safety and tolerability properties. Together, these data support further evaluation of ISM5939 as an anti-tumor agent."
