TAPI-2 is a broad-spectrum inhibitor of MMP (IC50: 20 μM), tumour necrosis factorα-converting enzyme (TACE) and a disintegrin and metalloproteinase (ADAM).
TNF-α antagonist is an exocyclic peptide that mimics the critical TNF-α recognition loop on TNF receptor I complex and, thus, prevents ligand interaction with the receptor. By blocking the TNF receptor ligand contact site, this peptide interferes with both activating receptor activator of NF-κB (RANK) and TNF-α's recruitment and activation of osteoclasts. TNF-α antagonist has been used to block bone resorption in the study of systemic bone loss in rheumatoid arthritis and inflammatory bone destruction.
TNF-α-IN-2 is a highly potent and orally bioavailable inhibitor of tumor necrosis factor alpha (TNFα), exhibiting an IC50 of 25 nM in the HTRF assay. It exerts its inhibitory effects by inducing conformational changes in the TNFα trimer upon binding, resulting in disrupted signaling when the trimer interacts with TNFR1. TNF-α-IN-2 holds promise as a valuable tool for investigating the pathogenesis of rheumatoid arthritis[1].
