  Effects of C7 substitutions in a high affinity microtubule-binding taxane on antitumor activity and drug transport

  摘要：

  Some C-7 modified analogs of 3, a taxane with high affinity for binding to microtubules, were prepared through multistep transformations. Most of the analogs, bearing less lipophilic C-7 substituents than propionyl in 3, exhibited comparable binding affinities to microtubules but less cytotoxicity against drug-sensitive as well as multidrug-resistant tumor cells overexpressing P-glycoprotein. In addition, these C7 modifications increased P-glycoprotein-mediated drug transport in both directions in a Caco-2 cell assay. (C) 2011 Elsevier Ltd. All rights reserved.

  Isolation, identification, semi-synthesis of aziditaxel derivatives and their biological evaluation

  摘要：

  Two new taxoids (5 and 6) were obtained by isolating impurities in aziditaxel, and their structures were characterized based on data analysis of H-1 NMR, C-13 NMR, HPLC-MS, and through comparison with literature. In order to test their cytotoxicities against human nonsmall lung cancer cell lines (A549), sufficient amounts of compounds 5 and 6 were obtained by semi-synthesis and both of them showed equipotent cytotoxiesty compared with taxol, docetaxel, and aziditaxel.
