Syntheses of structurally-simplified and fluorescently-labeled neovibsanin derivatives and analysis of their neurite outgrowth activity in PC12 cells
摘要:
The syntheses of several neovibsanin derivatives were carried out in order to elucidate the simple structure required for displaying neurite outgrowth activity. In addition, a fluorescent probe molecule was synthesized and the analysis of its behavior in the PC12 cell line showed that the neovibsanins accumulate on the outer edge of the cell at the site of formation of prominences.

Herein we report regioselective and mild reactions for the tert-butyldimethylsilyl mono-protection of 5-(2′-hydroxyethyl)cyclopent-2-en-1-ol (2) and 6-(2′-hydroxyethyl)cycohex-2-en-1-ol (5) at the primaryhydroxyl group or at the secondary allylic hydroxyl group. The different steric environment surrounding the secondary allylic and saturated primaryalcohols is mainly invoked to rationalize the observed
