OBJECTIVE: To synthesize desmosdumotin C derivatives on B-ring with antitumor activity. METHODS: The target compounds were synthesized from 2, 4, 6-trihydroxyacetophenone via methylation, O-methylation and aldol reaction. Their antiproliferative activities were tested against six human tumor cell lines. RESULTS: Fourteen target compounds were synthesized, nine of which were new compounds. All of them were characterized using 1H-NMR, 13C-NMR and MS. CONCLUSION: Preliminary pharmacological test showed that all the title compounds except 1i exhibited potent antitumor activities. 1h and 1n were better than desmosdumotin C in vitro. Introducing two fluoro atom on B-ring would benefit its activity against some tumor cells.

The study is aimed to investigate the effect of plant growth regulators on yield and quality of the Salvia miltiorrhiza. The plant growth regulators was spraying on Salvia plants in July or August in field experiment, then the yield, ingredient content and the antioxidant activity were determined. The results showed that plant growth regulator 'Zhuanggenling' could increase the yield of Salvia with root-planting by 38.45%. Plant growth regulator 'Duoxiaozuo' could increase the yield of Salvia with seedling planting by 14.19%. Both plant growth regulator significantly reduced the antioxidant activity of Salvia in vitro, but they had no significant effect on active ingredient contents.

Objective To evaluate the role and mechanism of miR-150 in cardiac fibrosis after MI.Methods A rat model of MI was established by up-regulating miR-150 through overexpressing miR-150 lentivirus.Real-time PCR and Western blot were applied in detecting the expression of collagen 1 α 1 and α-SMA protein in infarction area border.Masson coloration was applied in measuring fibrosis.Cardiac fibroblasts were isolated and cultured.UTR was used to report the carrier and lentivirus.And c-Myb siRNA was used to verify the relationship between c-Myb and microRNA-150.Results In vivo,MiR-150 was down-regulated in myocardium border zone in 14 day and 28 day after infarction (P ＜ 0.001,P ＜ 0.05),and overexpressing miR-150 promoted myocardial fibrosis (P ＜ 0.001),and inhibited the expression of collagen1α 1 and α-SMA (P ＜ 0.01,P ＜ 0.05).In vitro,c-Myb was the direct target gene of miR-150,and inhibited the expression of c-Myb resulting in the down regulation of collagen1α 1 and α-SMA,suggesting that the role of miR-150 was achieved by regulating c-Myb.Conclusions MiR-150 was down-regulated in myocardium border zone,and myocardial fibrosis can be improved by targeting c-Myb.

OBJECTIVE: To compare the pharmacokinetics of total glucosides of paeony (TGP) in rats with acute liver injury and normal rats, thus to provide evidence for determining dosage regimen in clinic. METHODS: Acute liver injury rat model was established by single CCl4 intraperitoneal injection. Three dosages of TGP were orally administered to normal and model rats. The concentrations of Pae and Alb in plasma at different time after dosing were determined with HPLC method. The pharmacokinetic parameters were calculated based on mean plasma concentration-time curves of Pae and Alb. RESULTS: In model rat group, the t1/2 of Pae and Alb at high, medium, and low dosage (0.047, 0.141, 0.282 g · mL-1) were 5.02, 4.52, 4.91 h and 5.22, 5.04, 5.05 h, respectively. The ρmax of Pae and Alb of TGP at different dosages were 22.54, 14.52, 5.49 μg · mL-1, and 9.02, 5.04, 2.34 μg · mL-1, respectively. The AUC0-t of Pae and Alb of TGP at different dosages were (146.55 ± 7.52), (84.14 ± 7.84), (31.62 ± 2.97) μg · h · mL-1, and (56.56 ±8.70), (32.18 ± 3.49), (13.48 ±1.66) μg · h · mL-1, respectively. The tmax of paeoniflorin(Pae) and albiflorin(Alb) of TGP at different dosages were both 2 h. In rats of normal group, the t1/2 of Pae and Alb of TGP at different dosages respectively were 3.95, 3.69, 3.95 h, and 3.74, 3.98, 3.79 h, respectively. The ρmax were 19.16, 11.60, 4.46 μg · mL-1, and 7.16, 4.00, 1.93 μg · mL-1, respectively. The AUC0-t were (116.26.6 ± 19.99), (67.74 ± 12.79), (25.01 ±2.62) μg · h · mL-1, and (45.03 ±5.84), (27.26 ±3.57), (10.59 ± 1.86) μg · h · mL-1, respectively. The tmax were both 2.5 h. CONCLUSION: Compared with normal group, the ρmax and AUC0-t of TGP in model group significantly increased, tmax decreased, and t1/2 prolonged; tmax and t1/2 had no difference among three dosages, and ρmax. and AUC0-t had correlation with dosage.
