1. Synthesis and activity evaluation of allyl-quercetin derivatives
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.

OBJECTIVETo observe the regulatory effects of electroacupuncture with different acupoints combinations on blood lipid and atherosclerosis index (AI) in rats with hyperlipemia, so as to make a preliminary screening for the optimal acupoints combination for hyperlipemia.
METHODSOne hundred and five clean-grade SD male rats were randomly divided into 9 groups, including a normal group, a model group, a Quchi group, a Zhongwan group, a Fenglong group, a Quchi+Zhongwan group, a Quchi+Fenglong group, a Zhongwan+Fenglong group and a Quchi+Zhongwan+Fenglong group (three acupoints group), 17 rats in the normal group and 11 rats in the rest groups. The normal group was fed with normal diet, while the rest groups were fed with high-fat diet for 3 weeks to prepare the hyperlipemia model. All the rats were given unlimited water. After the establishment of model, the normal group was fed freely without any treatment; the model group was bundled and immobilized everyday; the rest groups were bundled, immobilized and treated with electroacupuncture at corresponding acupoints with disperse-dense wave, 20 min per time, once a day. After 4 weeks, the blood examples were collected from abdominal aorta to measure the total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL-C) and low-density lipoprotein (LDL-C), and analyzed the AI in each group.
RESULTSAfter the treatment, TC, TG, HDL-C, LDL-C and AI in each acupuncture group were all lower than those in the model group (P<0.05, P<0.01). Compared with single acupoint group and the Quchi+Zhongwan group, the content of TC in the three acupoints group was lower (P<0.01). The differences of content of TG among each acupuncture group were not significant (all P>0.05). Compared with the rest 6 acupuncture groups, the content of HDL-C and AI in the three acupoints group were significantly different (all P<0.05). The content of LDL-C in the three acupoints group was decreased as compared with the Quchi group and the Zhong-wan group.
CONCLUSIONThe electroacupuncture at "Quchi" (LI 11), "Zhongwan" (CV 12) and "Fenglong" (ST 40) has more advantages on regulating the content of HDL-C and LDL-C as well as improving AI in hyperlipemia rats, and it has superior effects on blood lipid metabolism.
