| 1 | Comparative pharmacokinetics of tetramethylpyrazine phosphate in rat plasma and extracellular fluid of brain after intranasal,intragastric and intravenous administration显示文摘The purpose of this study was to compare the pharmacokinetic profiles of tetramethylpyrazine phosphate(TMPP)in plasma and extracellular fluid of the cerebral cortex of rats via three delivery routes:intranasal(i.n.),intragastric(i.g.)and intravenous(i.v.)administration.After i.n.,i.g.and i.v.administration of a single-dose at 10 mg/kg,cerebral cortex dialysates and plasma samples drawn from the carotid artery were collected at timed intervals.The concentration of TMPP in the samples was analyzed by HPLC.The area under the concentration-time curve(AUC)and the ratio of the AUCbrain to the AUCplasma(drug targeting efficiency,DTE)was calculated to evaluate the brain targeting efficiency of the drug via these different routes of administration.After i.n.administration,TMPP was rapidly absorbed to reach its peak plasma concentration within 5 min and showed a delayed uptake into cerebral cortex(t_(max)=15 min).The ratio of the AUCbrain dialysates value between i.n.route and i.v.injection was 0.68,which was greater than that obtained after i.g.administration(0.43).The systemic bioavailability obtained with i.n.administration was greater than that obtained by the i.g.route(86.33%vs.50.39%),whereas the DTE of the nasal route was 78.89%,close to that of oral administration(85.69%).These results indicate that TMPP is rapidly absorbed from the nasal mucosa into the systemic circulation,and then crosses the blood-brain barrier(BBB)to reach the cerebral cortex.Intranasal administration of TMPP could be a promising alternative to intravenous and oral approaches. | Dongmei Meng Haoyang Lu Shanshan Huang Minyan Wei Pingtian Ding Xianglin Xiao Yuehong Xu Chuanbin Wu | 2014 | Acta Pharmaceutica Sinica B2014，4，1： | 5 |
| 2 | Prussian blue nanosphere-embedded in situ hydrogel for photothermal therapy by peritumoral administration显示文摘To establish an injectable hydrogel containing Prussian blue(PB) nanospheres for photothermal therapy against cancer, PB nanospheres were prepared by one-pot synthesis and the thermosensitive Pluronic F127 was used as the hydrogel matrix. The PB nanospheres and the hydrogel were characterized by shape, particle size, serum stability, photothermal performance upon repeated 808 nm laser irradiation, as well as the rheological features. The effect of the PB nanospheres and the hydrogel were evaluated qualitatively and quantitatively in 4T1 mouse breast cancer cells. The retention,photothermal efficacy, therapeutic effects and systemic toxicity of the hydrogel were assessed in a tumor-bearing mouse model. The PB nanospheres had a diameter of about 150 nm and exhibited satisfactory serum stability, photo-heat convert ability and repeated laser exposure stability. The hydrogel encapsulation did not negatively influence the above features of the photothermal agent. The nanospherecontaining hydrogel showed a phase transition at body temperature and, as a result, a long retention time in vivo. The photothermal agent-embedded hydrogel displayed promising photothermal therapeutic effects in the tumor-bearing mouse model with little-to-no systemic toxicity after peritumoral administration. | Jijun Fu Bo Wu Minyan Wei Yugang Huang Yi Zhou Qiang Zhang Lingran Du | 2019 | Acta Pharmaceutica Sinica B2019，9，3： | 2 |

| 5 | Preparation of BaCe_(0.5)Zr_(0.4)Y_(0.1)O_(3-α) by Sol-Gel Method and Its Electrical Properties显示文摘A precursor of BaCe0.5Zr0.4Y0.1O3-α electrolytes was synthesized by the sol-gel method and sintered at temperature which were 150~250 ℃ lower than by solid state reaction. The AC impedance spectrums of electrolytes were measured by AUTOLAB PGSTA30 electrochemical measuring device at different temperatures. The conductivities of the electrolytes are 1.62×10-4~6.43×10-3, 2.52×10-5~3.73×10-3 S·cm-1 in the temperature range of 350~800 ℃. The activity energies are 0.54 and 0.84 eV. At the same time BaCe0.9Y0.1O3-α was prepared by direct solid state reaction. The conductivity of BaCe0.9Y0.1O3-α is 1×10-4~4×10-3 S·cm-1 and the activation energy is 0.50 eV at the same condition. The results show that conduction of electrolyte prepared by sol-gel method is higher than the one by solid state reaction. As far as BaCe0.9Y0.1O3-α concerned, its conductivity of the Zr-substituted specimens is decreased. | Wang Jie Ding Weizhong Fang Jianhui Zhu Dongdong Wu Minyan | 2005 | Journal of Rare Earths2005，23，4： | 1 |

| 7 | Ligand-Controlled Palladium-Catalyzed Regiodivergent Defluorinative Allylation of gem-Difluorocyclopropanes viaσ-Bond Activation显示文摘Monofluoroalkenes are important and versatile privileged components in pharmacologically relevant molecules.Here,we report a method for the selective construction of these compounds in a diversity-oriented fashion through regiodivergent cross-coupling of gem-difluorocyclopropanes with allylboronates by employing a palladium catalyst with two different ligands,in which gem-difluorocyclopropanes were used as allyl electrophiles by C—C and C—F bond activation.In the presence of 2-biphenylyl(diphenyl)phosphine as ligand,the linear-selective allyl–allyl bond formation is highly obtained,while utilizing the sterically hindered BrettPhos(dicyclohexyl[3,6-dimethoxy-2',4',6'-tris(1-methylethyl)[1,1'-biphenyl]-2-yl]phosphine)as the ligand favors the generation of the branched-selective product.Experimental and computational studies investigated the key steps of the cross-coupling reactions,revealing the origin of the ligand-controlled regiodivergence. | Lei Wu Minyan Wang Yong Liang Zhuangzhi Shi | 2022 | Chinese Journal of Chemistry2022，40，19： | 0 |
