TAPI-1
Based on 16 publication(s) in Google Scholar
TAPI-1 is a broad-spectrum MMP inhibitor and NF-κB p65 inhibitor that targets ADAM17/TACE, ADAM10 and other proteins. TAPI-1 reduces the proteolytic cleavage of membrane-bound TNF-α, decreases TNF-α levels, inhibits NF-κB pathway activation, and downregulates profibrotic markers. TAPI-1 reduces the proportion of proinflammatory immune cells, alleviates cardiac and airway fibrosis, and improves cardiac function after myocardial infarction. Meanwhile, TAPI-1 inhibits the viability, migration and invasion of esophageal squamous cell carcinoma cells, enhances the chemosensitivity of Cisplatin (HY-17394), induces apoptosis, and shows low toxicity to normal esophageal epithelial cells. TAPI-1 can be widely used in studies related to myocardial infarction-induced heart failure, severe traumatic tracheal stenosis, esophageal squamous cell carcinoma and other conditions.

TAPI-1 (1.25-20 μM; 24-72 h) inhibits viability of TE-1 and Eca109 ESCC cells in a dose- and time-dependent manner without affecting viability of normal Het-1A esophageal epithelial cells[3].
TAPI-1 (10 μM; 24 h) upregulates TRAIL mRNA in TE-1 ESCC cells but does not alter apoptosis-related gene expression in Eca109 ESCC cells; TAPI-1 (5 μM; 12 h) downregulates multiple Cisplatin (HY-17394) resistance-related genes in both TE-1 and Eca109 ESCC cells[3].
TAPI-1 (10 μM; 72 h) does not induce apoptosis in TE-1 or Eca109 ESCC cells, but TAPI-1 (5 μM; 48 h) enhances cisplatin-induced apoptosis in both TE-1 and Eca109 ESCC cells[3].
TAPI-1 (5 μM; 48 h) enhances the sensitivity of TE-1 and Eca109 ESCC cells to cisplatin, as shown by significantly reduced cisplatin IC50 values[3].
TAPI-1 (10 μM; 12 h) suppresses NF-κB signaling in TE-1 and Eca109 ESCC cells by reducing NF-κB p65 phosphorylation and nuclear translocation[3].
