Design and synthesis of pironetin analogues with simplified structure and study of their interactions with microtubules
摘要:
The preparation preparation of a series of pironetin analogues with simplified structure is described. Their cytotoxic activity and their interactions with tubulin have been investigated. It has been found that, while less active than the parent molecule, the pironetin analogues still share the mechanism of action of the latter and compete for the same binding site to alpha-tubulin. Variations in the configurations of their stereocenters do not translate into relevant differences between biological activities. (C) 2011 Elsevier Masson SAS. All rights reserved.

details of the total syntheses of the initially reported and revised structures of the neuroprotective agent palmyrolide A are reported. The key macrocyclization step was achieved using a sequential ring-closingmetathesis/olefin isomerization reaction. Furthermore, the totalsynthesis of the related macrolide (2S)-sanctolide A is reported. The synthesis used key elements from the synthesis of palmyrolide
