BAY 11-7082

CAS No. : 19542-67-7

MCE 国际站：BAY 11-7082

产品活性：BAY 11-7082 (BAY 11-7821) 是一种 IκBα 磷酸化和 NF-κB 抑制剂，选择性且不可逆地抑制 TNF-α 诱导的 IκB-α 磷酸化，并减少 NF-κB 和粘附分子的表达。BAY 11-7082 抑制泛素特异性蛋白酶 USP7 和 USP21 (IC₅₀分别为 0.19, 0.96 μM)。BAY 11-7082 抑制脂质体中的 gasdermin D (GSDMD) 孔形成以及炎性体介导的细胞凋亡和人和小鼠细胞中IL-1β的分泌。

研究领域：NF-κB  |  Cell Cycle/DNA Damage  |  Autophagy  |  Apoptosis

作用靶点：IKK  |  Deubiquitinase  |  Autophagy  |  Apoptosis  |  NF-κB

In Vitro: BAY 11-7082 (BAY 11-7821), an inhibitor of NF-κB, induces apoptosis of HTLV-I-infected T-cell lines but only negligible apoptosis of HTLV-I-negative T cells. Bay 11-7082 rapidly and efficiently reduces the DNA binding of NF-κB in HTLV-I-infected T-cell lines and down-regulated the expression of the antiapoptotic gene, Bcl-xL, regulated by NF-κB. Bay 11-7082 selectively inhibits Tax-induced NF-κB activity in a human T-cell line.
BAY 11-7082 inhibits NFκB signalling and is recently shown to inhibit the majority of E2 and E3 ligases tested by reacting covalently with the catalytic cysteine residues. Moreover, BAY 11-7082 also inhibits several tyrosine phosphatases by reacting with catalytic Cys residue of these enzymes. NSC 697923 is originally shown to inhibit the E2 ligase Ubc13-Uev1A.
BAY 11-7082 inhibits the phosphorylation of IκBα and activation of NF-κB, induces the death of HBL-1 cells. BAY 11-7082 completely suppresses the LPS-stimulated and IL-1-stimulated phosphorylation of the activation loop of IKKβ.
BAY 11-7082 acts by inhibiting TNF-α-induced phosphorylation of IκB-α, resulting in decreased NF-κB and decreases expression of adhesion molecules.

In Vivo: BAY 11-7082 (2.5 mg/kg and 5 mg/kg; intratumoral injection; twice-weekly for 21 days ) significantly suppresses tumor growth in a dose-dependent manner.
