  Modulation of multidrug resistance in tumor cells by taxinine derivatives

  摘要：

  Among a series of taxinine (1) and its designed derivatives (2 similar to 33), two taxoids (29 and 33) increased cellular accumulation of vincristine in multidrug-resistant tumor cells more potently than verapamil, while the activities of eight taxoids (11, 14 similar to 16, 22, and 30 similar to 32) were comparable with that of verapamil. These results reveal that some taxinine derivatives are good modifiers of multidrug resistance in tumor cells. (C) 1999 Elsevier Science Ltd. All rights reserved.

• Stereoselective epoxidation of 4(20)-exomethylene in taxinine derivatives and assignment of the epoxide orientation by NMR

  Epoxidation of taxinine (1), taxinine A (2), and taxinine derivative 7 with m-chloroperbenzoic acid afforded the α-4(20)-epoxides selectively (α : β = 99 : 1), while epoxidation of taxinine derivatives 7 and 8 with dimethyldioxirane gave the β-4(20)-epoxides predominantly (α : β = 1 : 4∼5). The epoxide orientation was found to be assignable by magnitude of chemical shift differences between the geminal

  日期：2003.3

  Three novel 4-deacetoxy-1,7-dideoxy azetidine paclitaxel analogues were synthesized through a convenient route that employed hydroboration-amination and intramolecular S(N)2-type substitution reaction from a natural taxoid taxinine. All analogues have been tested for cytotoxicity against three human tumor cell lines. None of them showed remarkable cytotoxicity compared to paclitaxel against tested tumor cell lines.
