Artemisinin (25 M) suppresses A25-35-induced LDH release, apoptosis and ROS production,attenuates A-induced mitochondrial membrane potential loss and caspase 3/7 activity incr
4、ease, andstimulates the phosphorylation of ERK1/2 in a time- and concentration-dependent manner in PC12 cell. ERK1/2 pathway mediates the protect effects of artemisinin in PC12 cells 1. Artemisinin shows cytotoxic activityin MCF-7/Dox cell line with IC50 of 3.70.4 g/mL after 24 h treatment. Besides,
5、 Artemisinin treatment ofMCF-7 cells, sensitive and resistant to Dox and DDP, causes a decrease in expression of proteins such asLF, FTH1, and HEP. Artemisinin activates p38 MAPK-kinase cascade regardless of the oxidative stress dueto inhibition of VEGF expression and cell migration 2. Artemisinin (
6、50, 100 or 200 mg) significantly inhibitsisoflurane-induced hippocampal neuronal loss, decreases caspase-3-positive cell counts and also cleavescaspase-3 expression, and modulates the expression of apoptosis pathway proteins. Artemisinin modulatesJNK/ERK 1/2 signalling and histone acetylation 3. Art

Artemisinin and its most potent analogues partially inhibit the in vitroreplication of HCV by induction of reactive oxygen species (ROS) 4. Artemisinin significantly inhibits VSMCproliferation in a dose-dependent

Artemisinin (1mM) for 72h significantly reduces the expression ofproliferating cell nuclear antigen messenger RNA 5.体内研究 Artemisinin (50, 100 or 200 mg/kg b.wt/day, p.o.) prevents isoflurane-induced working memory impairmentsas observed in T-maze test. Artemisinin enhances spatial navigatio
9、n and memory of rats exposed toisoflurane. Artemisinin-treated rats exhibit markedly better performance in comparison with isoflurane-alone-exposed rats 3.PROTOCOLKinase Assay 1 Briefly, PC12 cells are lysed in lysis buffer and centrifuged at 12,500g for 5 min 15 mL of cell lysate isincubated with 5
10、0 mL of 2X substrate working solution at room temperature for 30 min in 96-well plates. Thefluorescence intensity is then determined by Infinite M200 PRO Multimode Microplate at an excitationwavelength of 490 nm and emission at 520 nm. The fluorescence intensity of each sample is normalized tothe pr

They are for reference only.Cell Assay 2 For this purpose, cells are cultivated in 96-well plates in DMEM, supplemented with ins
12、ulin. The artemisinin,Dox, and DDP are added to media at different concentrations and the cells are cultivated for either 24 or 48h. For this purpose artemisinin is diluted in 0.01% DMSO in media. After this time, 10 L of the MTT dyesolution (5 mg/mL in phosphate buffer saline) is added to the cells
13、; the cells are incubated at the sameconditions for 3 h. After centrifugation (1500 rpm, 5 min) the supernatant is removed. 100 L of dimethylsulfoxide is added to each well, to dissolve formazan. The absorption is measured, using a multi-well2/3 Master of Small Molecules 您边的抑制剂师www.MedChemEspectroph
