ADAM17 inhibitor SN-4 is a newly identified, highly specific inhibitor of ADAM17 (A disintegrin and metalloproteinase 17), demonstrating potent activity in blocking TNF-α cleavage in cellular assays with an IC50 value of 3.22 µM. This compound exhibits slightly greater efficacy compared to marimastat, a well-established ADAM17 inhibitor. In vitro studies reveal that SN-4 effectively suppresses ADAM17-mediated cleavage of tumor necrosis factor α (TNF-α) and CD44, while showing no significant impact on ADAM10 activity. Additionally, SN-4 has been shown to inhibit cellular invasion, highlighting its potential as a targeted therapeutic agent for modulating ADAM17-related pathways.
