生物信息:

产品描述 A cell-permeable and irreversible antitumor and anti-inflammatory agent that acts as an inhibitor of 5-lipoxygenase (IC50=8μM) and cyclooxygenase (IC50=52μM). Confers significant protection against neurotoxic and genotoxic agents. Also inhibits the induction of nitric oxide synthase in activated macrophages (IC50=6μM). Recently shown to inhibit the EGF receptor intrinsic kinase activity in the human epidermoid carcinoma A431 cells in a dose- and time-dependent manner. Also shown to be a p300/CREB-binding protein-specific inhibitor of histone acetyltransferase, inhibiting the acetylation of histones H3 and H4 with an IC50 of ~25 μM. Does not affect p300/CREB binding protein-associated factor (PCAF).
信号通路 NF-κB
靶点 5-lipoxygenase COX Nitric Oxide Synthase
IC50 8μM 52μM 6μM
体外研究 Curcumin induced the expression of forkhead box protein O1 (FOXO1) through activation of extracellular signal-regulated kinase 1/2 signaling. Curcumin inhibited cell proliferation, which was associated with upregulation of the cyclin-dependent kinase inhibitors, p27 and p21, and downregulation of cyclin D1. Treatment of AGS and HT-29 cells with curcumin enhanced the cleavage of procaspase-3, -7, -8 and -9. Meanwhile, curcumin induced endoplasmic reticulum (ER) stress and mitochondrial dysfunction as evidenced by up-regulation of CCAAT/enhancer binding protein homologous protein (CHOP), phosphorylation of JNK and down-regulation of SERCA2ATPase, release of cytochrome c, decrease of Bcl-2 and reduction of mitochondrial membrane potential in both AGS and HT-29 cells. Curcumin upregulated protein level of NF-kappaB inhibitor IkappaBalpha and downregulated protein levels of c-Jun and AR in prostate cancer cell line.
体内研究 Chronic treatment with curcumin significantly reversed the CMS-induced behavioral abnormalities (reduced sucrose preference and decreased locomotor activity) in stressed rats. Additionally, curcumin effectively inhibited cytokine gene expression at both the mRNA and the protein level and reduced the activation of NF-κB.
