5-Hydroxy Lansoprazole Sulfide is an inhibitor of fatty acid synthase (FASN). FASN, which is responsible for de-novo synthesis of lipids, has been found to be overexpressed in cancerous tissue. 5-Hydroxy Lansoprazole Sulfide specifically inhibits enoyl reductase, and was found to more effectively inhibit FASN function than lansoprazole and was also more efficient at regulating NHEJ repair of oxidative DNA damage via PARP1.
Matrix metalloproteinase-3 (MMP-3), also known as stromelysin-1, is a critical enzyme involved in tissue remodeling and repair through its role in degrading extracellular matrix proteins, facilitating cell migration. This enzyme has been implicated in various physiological processes including vascular remodeling associated with aneurysm formation, wound healing, the progression of atherosclerosis, and tumor initiation. MMP-3 inhibitor VIII, a cell-permeable sulfonamide-based hydroxamic acid, effectively inhibits MMP-3 by binding to its active site (Ki = 23 nM), thus blocking its enzymatic activity. Additionally, this inhibitor has been demonstrated to suppress the activity of mouse macrophage metalloelastase MME MMP-12, with an IC50 value of 13 nM, highlighting its potential utility in research on tissue remodeling and disease processes involving MMPs.
