Chemical structure
| Cell experiment [1, 2]: | |
Cell lines | Activated RAW 264.7 cells and whole blood, vascular smooth muscle cell |
Preparation method | The solubility of this compound in DMSO is > 10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months. |
Reacting condition | 17–20 h |
Applications | Cardamonin inhibited NO and PGE2 production from lipopolysaccharide- and IFNγ-induced RAW cells and whole blood with IC50 values of 11.4 μM and 26.8 μM, respectively. In whole blood, cardamonin inhibited the generation of TxB2. Cardamonin dose-dependently inhibited the generation of intracellular reactive oxygen species and secretion of TNF-α from RAW 264.7 cells with IC50 values of 12.8 μM and 4.6 μM, respectively. Treatment with Cardamonin (37, 74, or 111 μM) inhibited Ang II-induced proliferation of rat VSMCs. Cardamonin suppressed Ang II-stimulated migration of rat VSMCs. |
| Animal experiment [3, 4]: | |
Animal models | Female ICR mice, Male Sprague-Dawley rats |
Dosage form | Intraperitoneal injection, 0.02-20 mg/kg, daily for 4 consecutive days; oral administration, 3-30 mg/kg |
Application | In female ICR mice, Cardamonin (0.02–2 mg/kg, i.p.) inhibited NO production. In male Sprague-Dawley rats, Cardamonin (3-30 mg/kg, oral administration) significantly inhibited PBQ-induced writhing. Cardamonin dose-dependently increased the withdrawal response latencies in carrageenan-induced hyperalgesia. |
Other notes | Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |

IC50: 1.2 μM (NF-κB activation) [1]
Cardamonin (2′,4′-dihydroxy-6′-methoxychalcone), a chalcone isolated from the fruits of Alpinia rafflesiana, shows anti-inflammatory activity by targeting the nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) pathway. NF-κB is a protein complex that controls cytokine production, transcription of DNA and cell survival.
In vitro: Cardamonin is a potential anti-inflammatory drug that targets the NF-κB pathway, which leads to suppress both NO and PGE2 synthesis, iNOS and COX-2 expression and enzymatic activity. The inhibition activation was due to a dose-dependent inhibition of phosphorylation and degradation of I-κBα, which resulted in a reduction of p65 NF-κB nuclear translocation [2]. Cardamonin also appears to inhibit prostaglandin E2, thromboxane B2 production, tumor necrosis factor a (TNF-a) release, and intracellular reactive oxygen species generation, all in a dose-dependent manner [3]
In vivo: Cardamonin shows protective effects on acute lung injury in sepsis. In mice, the results showed that cardamonin decreases systemic inflammatory responses, during sepsis, by downregulating TNF-a and interleukins [3].
Clinical trial: So far, no clinical study has been conducted.

上海好多的供应商的，具体还是看你选择了，其实试剂盒产品都差不多，什么远慕生物，古朵生物...好多的额
用双氧水去除过氧化物酶时，我是自己配的3%双氧水滴到片上而非将片浸入双氧水，这样可否？
用博士德的DAB染色，配制方法为：1mlH20中加入DAB、H2O2、TBS各一滴，我配制的时候发现将DAB加入H20时很容易沉淀，要震荡才能混匀，且将配好的DAB滴到玻片上时，DAB会结为很小块的微颗粒悬浮在液体中但并不染色，是否DAB有问题？
现在打算换中衫的试剂盒，代理商说中衫的试剂盒包括了二抗和DAB，想请教一下该试剂盒的具体内容有些什么？
万分感谢！
