TL000724939-16-0
Bisdemethoxycurcumin (Curcumin III) is a natural demethoxy derivative of curcumin. It is a potent activator of macrophage phagocytosis, interacting with 1α, 25-dihydroxy vitamin D3 to stimulate amyloid-β clearance by macrophages (optimal stimulation at 100 nM BDMC) [1]. More stable than curcumin in physiological media, BDMC suppresses proliferation of cancer cells [2]. It down-regulates the transcriptional coactivator p300, suppressing the Wnt/β-catenin pathway, and inhibits LPS induction of iNOS expression [3].

Chemical Properties
| Description | CPI203 (CPI 203) is an effective BET bromodomain inhibitor (IC50: 37 nM for BRD4). |
| Targets&IC50 | BET BD:37 nM |
| In vitro | CPI203 inhibits BRD4 in vitro and in cells, while does not affect BRD4 kinase activity in vitro. [1] CPI203 exerts a cytostatic effect in all the 9 MCL cell lines analyzed with GI50 ranging from 0.06 to 0.71 μM, with low cytotoxicity in normal PBMCs from healthy donors. Furthermore, lenalidomide and CPI203, by targeting IRF4 and MYC, efficiently activates the cell death program in MCL cells resistant to bortezomib. [2] |
| Kinase Assay | BRD4 α-screen assay: The BRD4 α-screen assay is a proximity-based assay using a tetraacteylated H4 peptide and the isolated bromodomain 1 of human BRD4. IC50 values are calculated using a 10-point serial dilution of BET inhibitor. |
| Cell Research | MCL primary cells and cell lines are incubated as indicated with lenalidomide and/or CPI203. MTT is added for 2-6 additional hours before spectrophotometric measurement. Each measurement is made in triplicate. Values are represented using untreated control cells. The GI50 is calculated as the concentration that produced 50 % growth inhibition. Combination indexes (CIs) are calculated by using the Calcusyn software version 2.0. The interaction between two drugs is considered synergistic when CI <1. (Only for Reference) |

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
For example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . A total of 10 animals were administered, and the formula you used is 5% 
DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSO (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
