3,4,5-Tricaffeoylquinic acid (3,4,5-triCQA) inhibits tumor necrosis factor-α-stimulated production of inflammatory mediators in keratinocytes via suppression of Akt- and NF-κB-pathways. 3,4,5-Tricaffeoylquinic acid induces cell cycle arrest at G0/G1, actin cytoskeleton organization, chromatin remodeling, neuronal differentiation, and bone morphogenetic protein signaling in human neural stem cells. 3,4,5-Tricaffeoylquinic acid has the potential for the research of aging-associated diseases.
In Vitro
3,4,5-Tricaffeoylquinic acid (0-50 μM) reduces TNF-α-induced production of cytokines in HEK001 keratinocytes. 3,4,5-Tricaffeoylquinic acid (15 μM, 35 min) inhibits TNF-α-induced IkBα phosphorylation and activation of NF-κB. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Cell Viability AssayCell Line: Keratinocytes Concentration: 15, 25 and 50 μM Incubation Time: 24 hours Result: Cell death was cell ∼4-5% at 15 and 25 μM, ∼9% at 50 μM. Western Blot AnalysisCell Line: Keratinocytes Concentration: 15 μM Incubation Time: 20 min before 10 ng/mL TNF-α addition for 15 min Result: Decreased TNF-α-induced-IkBα phosphorylation of IkBα and levels of cytosolic NF-Κb p65, cytosolic NF-Κb p65.
