Chinese Pharmaceutical Journal 2017;52(9):738-742
OBJECTIVE: To investigate the anti-proliferation effects of andrographolide Derivative(ADA) and its potential anti-tumor mechanisms in MCF-7 cells. METHODS The anti-proliferation effects of ADA were assessed by MTT assay in MCF-7 cells. Apoptotic morphological changes of MCF-7 cells after ADA treatment were observed by high content screening (HCS) after AO/EB double staining and DAPI, Apoptotic number was investigated by using flow cytometry. The expression of Bcl-2, Bax, caspase 3, NF-κB p65, p-IκBɑ and p-IKKβ were measured using Western blot. RESULTS: MTT assay demonstrated that ADA exerted potent anti-tumor effect in a significant concentration-dependent manner;ADA could promote the apoptosis of MCF-7 cells. Western blot results showed that Bcl-2 families and NF-κB p65 and caspase 3 involved in the process of apoptosis, Bcl-2 expression lowered(P<0.05), p-IκBɑ and p-IKKβ expression decreased(P<0.01), Bax, NF-κB p65 and caspase 3 expression increased(P<0.01). CONCLUSION: ADA could inhibit the proliferation of MCF-7 cells and mechanism may be that it might induce apoptosis by regulated the expression of Bax, Bcl-2 and caspase 3 protein and NF-κB passway.

Recombinant proteins provide new means for disease treatment, while creating considerable economic benefits. Using commercial crops (mainly tobacco), cereal crops, legumes, and vegetable crops to produce recombinant proteins with medicinal value is a hot-spot for research in "molecular farming". Although many recombinant proteins have been expressed in plants, only a small number have been successfully put into use. To overcome the problems that greatly hamper the development of recombinant protein production in plants, researchers have improved expression systems to increase the yield of recombinant proteins. Starting from analyzing the problems of low yield and/or low biological activity of recombinant proteins produced by plants, the optimization strategies to solve these problems were reviewed, and future research directions for improving the yield of recombinant proteins produced by plants were proposed.

Chinese Traditional and Herbal Drugs 2014;45(7):965-972
Objective: To observe the in vivo tissue distribution of 6-gingerols, 6-shogaol, and 8-gingerols from dried ginger (the rhizome of Zingiber officinale) in rats and to discuss the channel tropism of them. Methods: The method of "symptoms-efficacy-pharmacokinetics" was used and the ginger solution was ig given to the rats which were deficiency-cold in spleen and stomach; Then the blood, heart, liver, spleen, lung, kidney, brain, stomach, large intestine, and small intestine were immediately taken out after the rats were ig given the medince in 10, 20, 40, 60, 80, 120, and 360 min, respectively; Finally, HPLC was used to detect the concentration of 6-gingerols, 6-shogaol, and 8-gingerols from dried ginger in different tissues of rats in each group of deficiency-cold in spleen and stomach and normal by calculating the pharmacokinetic parameters. Results: We found that in the group of deficiency-cold in spleen and stomach, the concentration of the three active components was the highest in stomach, small intestine, liver, and lung, and in the group of normal, the three components were mostly distributed in the stomach, kidney, small intestine, large intestine, and lung. What's more, in the digestive organs, such as stomach and small intestine, the concentration was obviously higher in the group of deficiency-cold in spleen and stomach than that in the group of normal. Conclusion: The main ingredients of dried ginger mostly distribute in spleen, stomach, lung, and liver. This view conform to the traditional channel trpism of dried ginger in traditional Chinese medicine theory.

Chinese Pharmaceutical Journal 2016;51(6):442-448
OBJECTIVE: To design and synthesize two kinds of allyl-substituted quercetin and investigate their anti-oxidation and anti-tumor activities in vitro. METHODS: The target compounds 1 and 2 were first synthesized from quercetin by hydroxyl protection, allylation,Claisen rearrangement and deprotection. The anti-oxidation and anti-tumor activities of the target compounds and intermediate products were evaluated by DPPH and MTT assay. RESULTS: Eight compounds were synthesized,including six intermediates and two target compounds,in which four were new compounds. All of them were confirmed by 1H-NMR,13C-NMR and LC-MS spectra. The anti-oxidation and anti-tumor tests showed that compounds 1,2,5,6,8 and 9 had anti-oxidation activities and compound 5 inhibited A549 lung cancer cell proliferation. Compound 9 could inhibit the proliferation of lung cancer A549 cells and HepG2 cells. CONCLUSION: The compounds with electron-donating groups have significant anti-oxidant activity. When acetyl and methyl ether groups are used as the protecting groups,the position of introducing allyl group to quercetin has obvious impact on the anti-tumor activity.
