TNF-α converting enzyme (TACE, also known as ADAM17) is a zinc metalloprotease that cleaves the membrane-bound precursor of TNF-α to give the mature soluble form of TNF-α. It also mediates the proteolytic release of several other cell-surface proteins, including TNF-α receptors (TNFRs). TAPI-1, known in the earlier literature as just TAPI, is an inhibitor of TACE that inhibits the cleavage of TNF-α, TNFRI (p60), and TNFRII (p80) with IC values ranging from 5-100 µM. It also blocks the shedding of other TACE-dependent proteins, including IL-6R and Klotho, and may inhibit metalloproteases other than TACE. TAPI-1 differs from TAPI-0 , structurally, by the presence of an aminoethyl addition at the alanyl group, and is generally more stable in tissue culture and in vivo.
TAPI-1 is a TACE (ADAM17) inhibitor and blocks the shedding of several cell surface proteins. TAPI-1 is also a metalloproteinase (MMP) inhibitor.

体外研究
TAPI-1 can reduce the shedding of various membrane proteins, including the exon domain of amyloid precursor protein (APP) (sAPP α). TAPI-1 can inhibit the release of sAPP α stimulated by muscarinic acetylcholine receptor M3, suppress TACE dependent sAPP α release in TACE overexpressing cells, and inhibit sAPP α release in non TACE overexpressing cells, with IC50 values of 3.61, 0.92, and 8.09 μM, respectively.
