Nrf2 activator-24 is a Nrf2 activator with anti-inflammatory and antioxidant activities. Nrf2 activator-24 promotes the nuclear translocation of Nrf2, thereby inducing the expression of downstream antioxidant and cytoprotective genes. Nrf2 activator-24 inhibits cytokine-driven inflammatory responses in keratinocytes. Nrf2 activator-24 attenuates inflammation, nitrosation and oxidative stress responses in macrophages. Nrf2 activator-24 alleviates local inflammation and atopic dermatitis-like symptoms in DNCB-induced mouse models. Nrf2 activator-24 can be used in research related to atopic dermatitis.

Description

Nrf2 activator-24 is a Nrf2 activator with anti-inflammatory and antioxidant activities. Nrf2 activator-24 promotes the nuclear translocation of Nrf2, thereby inducing the expression of downstream antioxidant and cytoprotective genes. Nrf2 activator-24 inhibits cytokine-driven inflammatory responses in keratinocytes. Nrf2 activator-24 attenuates inflammation, nitrosation and oxidative stress responses in macrophages. Nrf2 activator-24 alleviates local inflammation and atopic dermatitis-like symptoms in DNCB-induced mouse models. Nrf2 activator-24 can be used in research related to atopic dermatitis[1].

In Vitro

Nrf2 activator-24 (various concentrations; 6 h) potently induces Nrf2 nuclear translocation in engineered U2OS cells with an EC50 of 4.9 ± 0.3 nM[1].
Nrf2 activator-24 (up to 1 μM; 24 h) is non-cytotoxic to HaCaT human keratinocytes[1].
Nrf2 activator-24 (0.1 μM; up to 24 h) induces peak Nrf2 nuclear translocation in HaCaT human keratinocytes at 3 h post-treatment, with levels decreasing thereafter up to 24 h[1].
Nrf2 activator-24 (increasing concentrations; 6 h (Nrf2), 12 h (HO-1, GCLM)) induces concentration-dependent increases in Nrf2, HO-1, and GCLM protein expression in HaCaT human keratinocytes, with maximal effects at 1 μM[1].
Nrf2 activator-24 (increasing concentrations; 6 h) induces concentration-dependent increases in HMOX1, GCLM, GCLC, and NQO1 mRNA expression in HaCaT human keratinocytes, with maximal effects at 1 μM[1].
Nrf2 activator-24 (0.03-1 μM; 3 h pretreatment, 24 h cytokine stimulation) concentration-dependently suppresses IL-1β protein expression in TNF-α+IFN-γ-stimulated HaCaT human keratinocytes[1].
Nrf2 activator-24 (0.03-1 μM; 6 h pretreatment, 3 h cytokine stimulation (IL6, TNF); 24 h cotreatment (CCL17, CCL22)) concentration-dependently suppresses IL6, TNF, CCL17, and CCL22 mRNA expression in TNF-α+IFN-γ-stimulated HaCaT human keratinocytes[1].
Nrf2 activator-24 (0.03-1 μM; 3 h pretreatment, 24 h LPS stimulation) concentration-dependently suppresses iNOS protein expression in LPS-stimulated Raw264.7 mouse macrophages[1].
Nrf2 activator-24 (0.03-1 μM; 3 h pretreatment, 24 h LPS stimulation) concentration-dependently suppresses NO production in LPS-stimulated Raw264.7 mouse macrophages[1].
Nrf2 activator-24 (0.1 μM; 9 h pretreatment) effectively reduces H2O2-induced intracellular ROS levels in Raw264.7 mouse macrophages[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
