生物活性

Bisdemethoxycurcumin(Curcumin III; Didemethoxycurcumin) is a natural derivative of curcumin with anti-inflammatory and anti-cancer activities. IC50 value: Target: Anticancer natural compound in vitro: BDMC-inducedapoptosiswas mediated by a combinatory inhibition of cytoprotective proteins, such as Bcl2 and heme oxygenase-1 and increased generation ofreactive oxygen species. Intriguingly, BDMC-inducedapoptosiswas reversed with co-treatment of sr144528, acannabinoid receptor(CBR) 2 antagonist, which was confirmed with genetic downregulation of the receptor using siCBR2 [1]. Induction of cell cycle arrest in HepG2 cells by NB and BDCur in combination was evidenced by accumulation of the G2/M cell population. Further investigation on the molecular mechanism showed that NB and BDCur in combination resulted in a significant decrease in the expression level of Cdc2 and cyclin B [2]. BDMC treatment activated Sirt1/AMPK signaling pathway. Moreover, downregulatingSirt1by the pharmacological inhibitor nicotianamine orsmall interfering RNAblocked BDMC-mediated protection against t-BHP-mediated decrease in proliferation [4]. in vivo: human gastric adenocarcinoma xenograft model was generated in vivo using nude mice and BDMC was observed to suppress the growth and activity of tumors, in addition to improving the physical and mental capacity of the mice [3].

请依序添加每种溶剂： 10% DMSO 40%PEG300 5%Tween-80 45% saline
Solubility: ≥ 2.5 mg/mL (8.11 mM); Clear solution
此方案可获得 ≥ 2.5 mg/mL (8.11 mM，饱和度未知) 的澄清溶液。
以 1 mL 工作液为例，取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中，混合均匀；向上述体系中加入50 μL Tween-80，混合均匀；然后继续加入 450 μL生理盐水定容至 1 mL。
将 0.9 g 氯化钠，完全溶解于 100 mL ddH2O 中，得到澄清透明的生理盐水溶液
