|Biological Activity or Inhibitors:||1. 3,4,5-Tricaffeoylquinic acid may attenuate the TNF-α- and LPS-stimulated production of inflammatory mediators in keratinocytes by suppressing the Toll-like receptor 4 expression-mediated activation of the Akt, ERK and NF-ĸB pathways, it may exert an inhibitory effect against the pro-inflammatory mediator-induced skin disease.
2. 3,4,5-Tricaffeoylquinic acid may attenuate the proteasome inhibitor-induced programmed cell death in PC12 cells by suppressing the activation of the mitochondrial pathway and the caspase-8- and Bid-dependent pathways, the effect be attributed to its inhibitory effect on the formation of reactive oxygen species and depletion of GSH.
|Solvent:||Pyridine, Methanol, Ethanol, etc.|
|Storage:||Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

|3,4,5-tricaffeoylquinic acid attenuates proteasome inhibition-mediated programmed cell death in differentiated PC12 cells.[Pubmed: 24825618]|
|The dysfunction of the proteasome system is suggested to be implicated in neuronal degeneration. Caffeoylquinic acid derivatives have demonstrated anti-oxidant and anti-inflammatory effects. However, the effect of 3,4,5-Tricaffeoylquinic acid on the neuronal cell death induced by proteasome inhibition has not been studied. Therefore, in the respect of cell death process, we assessed the effect of 3,4,5-Tricaffeoylquinic acid on the proteasome inhibition-induced programmed cell death using differentiated PC12 cells. The proteasome inhibitors MG132 and MG115 induced a decrease in Bid, Bcl-2, and survivin protein levels, an increase in Bax, loss of the mitochondrial transmembrane potential, cytochrome c release, activation of caspases (-8, -9 and -3), and an increase in the tumor suppressor p53 levels. Treatment with 3,4,5-Tricaffeoylquinic acid attenuated the proteasome inhibitor-induced changes in the programmed cell death-related protein levels, formation of reactive oxygen species, GSH depletion and cell death. The results show that 3,4,5-Tricaffeoylquinic acid may attenuate the proteasome inhibitor-induced programmed cell death in PC12 cells by suppressing the activation of the mitochondrial pathway and the caspase-8- and Bid-dependent pathways. The preventive effect of 3,4,5-Tricaffeoylquinic acid appears to be attributed to its inhibitory effect on the formation of reactive oxygen species and depletion of GSH.|

|3,4,5-Tricaffeoylquinic acid inhibits tumor necrosis factor-α-stimulated production of inflammatory mediators in keratinocytes via suppression of Akt- and NF-κB-pathways.[Pubmed: 21704193]|
|Keratinocytes may play an important role in the pathogenesis of skin disease in atopic dermatitis. Caffeoyl derivatives are demonstrated to have anti-inflammatory and anti-oxidant effects. However, the effect of 3,4,5-Tricaffeoylquinic acid prepared from Aconium koreanum on the pro-inflammatory cytokine-stimulated keratinocyte responses remains uncertain. In human keratinocytes, we investigated the effect of 3,4,5-Tricaffeoylquinic acid on the tumor necrosis factor (TNF)-α-stimulated production of inflammatory mediators in relation to the nuclear factor (NF)-κB and cell signaling Akt, which regulates the transcription genes involved in immune and inflammatory responses. 3,4,5-Tricaffeoylquinic acid inhibited the TNF-α-stimulated production of cytokines (IL-1β and IL-8) and chemokine (CCL17 and CCL27) in keratinocytes. Bay 11-7085 (an inhibitor of NF-κB activation) and Akt inhibitor attenuated the TNF-α-induced formation of inflammatory mediators. 3,4,5-Tricaffeoylquinic acid, Bay 11-7085, Akt inhibitor and N-acetylcysteine inhibited the TNF-α-induced activation of NF-κB, activation of Akt, and formation of reactive oxygen and nitrogen species. The results show that 3,4,5-Tricaffeoylquinic acid seems to attenuate the TNF-α-stimulated inflammatory mediator production in keratinocytes by suppressing the activation of Akt and NF-κB pathways which may be mediated by reactive oxygen species. The findings suggest that 3,4,5-Tricaffeoylquinic acid may exert an inhibitory effect against the pro-inflammatory mediator-induced skin disease.|
|3,4,5-tricaffeoylquinic Acid inhibits the lipopolysaccharide-stimulated production of inflammatory mediators in keratinocytes.[Pubmed: 22947851 ]|
|BACKGROUND AND PURPOSE: Microbial product lipopolysaccharide (LPS) has been shown to be involved in the pathogenesis of inflammatory skin diseases. Caffeoyl derivatives have demonstrated anti-inflammatory and antioxidant effects. However, the effect of 3,4,5-Tricaffeoylquinic acid (3,4,5-triCQA) on the production of microbial product-induced inflammatory mediators in keratinocytes has not yet been studied. EXPERIMENTAL APPROACH: Using human keratinocytes, we investigated the effect of 3,4,5-Tricaffeoylquinic acid on the LPS-stimulated production of inflammatory mediators in relation to the nuclear factor (NF)-ĸB, Akt and ERK pathways. RESULTS: 3,4,5-Tricaffeoylquinic acid inhibited the LPS-induced expression of Toll-like receptor 4, and the production of cytokines and chemokines in keratinocytes. 3,4,5-Tricaffeoylquinic acid, Bay 11-7085, Aĸt inhibitor and ERK inhibitor each attenuated the LPS-induced production of inflammatory mediators by inhibiting the NF-ĸB, Akt and ERK pathways. CONCLUSIONS AND IMPLICATIONS: 3,4,5-Tricaffeoylquinic acid may attenuate the LPS-stimulated production of inflammatory mediators in keratinocytes by suppressing the Toll-like receptor 4 expression-mediated activation of the Akt, ERK and NF-ĸB pathways. 3,4,5-Tricaffeoylquinic acid may exert a preventive effect against microbial product-induced inflammatory skin diseases.|
