| 产品描述 | Vialinin A is a potent inhibitor of ubiquitin-specific peptidases with IC50 values of 1.5, 5.9 and 22.3 μM for ubiquitin-specific peptidase 4 (USP4), USP5/isopeptidase T (IsoT) and UCH-L1 deubiquitinating enzyme (DUB), respectively [1]. Ubiquitin-specific peptidases (USPs) are a series of proteases that deubiquitinate target proteins. The dynamic modification of a protein with ubiquitin can modify its function, localization and fate in the cell. Ubiquitin hydrolase plays an important role in immunology and infection [2]. In RBL-2H3 cells, vialinin A inhibited TNF-ɑ production and release and inhibited USP5 enzymatic activity. In USP5 siRNA-knockdown RBL-2H3 cells, vialinin A inhibited TNF-ɑ production and release in a dose dependent way. Also, the mRNA expression of TNF-ɑ was decreased significantly [2]. In RBL-2H3 cells, Vialinin A inhibited TNF-ɑ production with IC50 value of 0.09 nM. Also, it inhibited the release of interleukin 4, β-hexosaminidase and monocyte chemotactic protein 1, which suggested Vialinin A had anti-allergic activities [3]. References: |
