  Synthesis and Evaluation of 2′-Hydroxyethyl trans-Apovincaminate Derivatives as Antioxidant and Cognitive Enhancer Agents

  摘要：

  A series of trans-2'-hydroxyethyl and 2'-acyloxyethyl apovincaminates 4b-f and 7b-f has been synthesized and evaluated for their antioxidant and antiamnesic effects. The new esters were prepared from 4a and 7a ethyl esters or from the corresponding carboxylic acid sodium salt. For starting materials 11a,b, a new stereoselective trans-reduction was elaborated. From the combined results of the data obtained from in vitro and in vivo tests and examination of the metabolism, (3R,16S)-2'-hydroxyethyl apovincaminate (7b, RGH-10885) was identified as the most promising compound, owing to its potent neuroprotective and antiamnesic activities. The in vivo effectiveness of selected compounds on the cognitive functions was studied in a one-trial passive avoidance task and a water-labyrinth test.

  长春胺手性杂质的制备方法

  摘要：

  本发明涉及长春胺手性杂质的制备方法。本发明通过定向合成的方法，以及后期的柱层析分离，从而得到了七个手性杂质的高纯品，并将其用于长春胺生产中的杂质定性和定量的分析，实现了长春胺药物中七个手性杂质分离确认，并提高了长春胺的药品质量标准，从而能够获得高纯度的长春胺。与现有的长春胺的制备方法相比，本发明涉及到了七个手性异构体的制备，制备方法更加的全面，且操作简单。
