1Solid lipid nanoparticles for nose to brain delivery of haloperidol:in vitro drug release and pharmacokinetics evaluation显示文摘In the present study,haloperidol(HP)-loaded solid lipid nanoparticles(SLNs)were prepared to enhance the uptake of HP to brain via intranasal(i.n.)delivery.SLNs were prepared by a modified emulsification-diffusion technique and evaluated for particle size,zeta potential,drug entrapment efficiency,in vitro drug release,and stability.All parameters were found to be in an acceptable range.In vitro drug release was found to be 94.1674.78%after 24 h and was fitted to the Higuchi model with a very high correlation coefficient(R2¼0.9941).Pharmacokinetics studies were performed on albino Wistar rats and the concentration of HP in brain and blood was measured by high performance liquid chromatography.The brain/blood ratio at 0.5 h for HP-SLNs i.n.,HP sol.i.n.and HP sol.i.v.was 1.61,0.17 and 0.031,respectively,indicating direct nose-to-brain transport,bypassing the blood-brain barrier.The maximum concentration(Cmax)in brain achieved from i.n.administration of HP-SLNs(329.17720.89 ng/mL,Tmax 2 h)was significantly higher than that achieved after i.v.(76.9577.62 ng/mL,Tmax 1 h),and i.n.(90.1376.28 ng/mL,Tmax 2 h)administration of HP sol.The highest drug-targeting efficiency(2362.43%)and direct transport percentage(95.77%)was found with HP-SLNs as compared to the other formulations.Higher DTE(%)and DTP(%)suggest that HP-SLNs have better brain targeting efficiency as compared to other formulations.Mohd Yasir Udai Vir Singh Sara 2014Acta Pharmaceutica Sinica B2014,4,6:5

3Identification,synthesis and characterization of an unknown process related impurity in eslicarbazepine acetate active pharmaceutical ingredient by LC/ESI-IT/MS,~1H,^(13)C and ~1H-~1H COSY NMR显示文摘A new impurity was detected during high performance liquid chromatographic(HPLC) analysis of eslicarbazepine acetate active pharmaceutical ingredient.The structure of unknown impurity was postulated based on liquid chromatography mass spectrometry using electrospray ionization and ion trap analyzer(LC/ESI-IT/MS) analysis.Proposed structure of impurity was unambiguously confirmed by synthesis followed by characterization using ~1H,^(13)C nuclear magnetic resonance spectrometry(NMR),~1H-~1H correlation spectroscopy(COSY) and infrared spectroscopy(IR).Based on the spectroscopic and spectrometric data,unknown impurity was characterized as 5-carbamoyl-10,11-dihydro-5H-dibenzo[b,f]azepin-10-yl propionate.Saji Thomas Saroj Kumar Paul Subhash Chandra Joshi Vineet Kumar Ashutosh Agarwal Dharam Vir 2014Journal of Pharmaceutical Analysis2014,4,5:2

15关于草药标准化的研究综述(英文)显示文摘由于自然产品有化学多样性的特点,使之具有很高的实用性,无论是作为纯天然化合物或是标准化植物提取物,它们都为新药的开发提供了很多可能。与现代西药比较,草药通常被用于治疗慢性疾病。规范化操作可保证植物的一个或多个活性成分及化合物的含量。在新药研发方面,植物药的开发成本较低且资源丰富,但植物的生长环境和基因等因素会在很大程度上影响植物提取物的生物化学成分。植物药的生产要求源植物在基因方面的单种栽培完全符合标准条件,以保证其生物化学指标的一致性,并可以优化植物药的安全性和有效性。本文旨在讨论如何改进植物药提取的规范化操作方法以及如何有效制备质量及效果稳定的植物药。Vandana Garg Vir Ji Dhar Anupam Sharma Rohit Dutt 2012中西医结合学报2012,10,10:1
