Convergent synthesis of fluorescence-labeled probes of Annonaceous acetogenins and visualization of their cell distribution
摘要:
The convergent synthesis of fluorescence-labeled solamin, an antitumor Annonaceous acetogenin, was accomplished by two asymmetric alkynylations of 2,5-diformyl tetrahydrofuran with an alkyne tagged with fluorescent groups and another alkyne with an alpha,beta-unsaturated gamma-lactone. Assay for the growth inhibitory activity against human cancer cell lines revealed that the probe with the fluorescent groups at the end of the hydrocarbon chain may have the same mode of action as natural acetogenins. The merged fluorescence of dansyl-labeled solamin and MitoTracker Red suggests that Annonaceous acetogenins localize in the mitochondria. (C) 2010 Elsevier Ltd. All rights reserved.

Synthesis of dansyl-labeled probe of thiophene analogue of annonaceous acetogenins for visualization of cell distribution and growth inhibitory activity toward human cancer cell lines
The convergent synthesis of the dansyl-labeled probe of the thiophene-3-carboxamide analogue of annonaceous acetogenins, which shows potent antitumor activity, was accomplished by two asymmetric alkynylations of the 2,5-diformyl THF equivalent with an alkyne having a thiophene moiety and another alkyne tagged with a dansyl group. The growth inhibitory profiles toward 39 human cancer cell lines revealed that the probe retained the biological function of its mother compound, and would be useful for studying cellular activity.

Convergent Synthesis of Fluorescence Labeled Solamin
The convergent synthesis of dansyl-labeled solamin, an antitumor Annonaceous acetogenin, has been achieved. The carbon skeleton was assembled from three fragments: the THF ring fragment, the fluorescent fragment, and the gamma-lactone fragment, by asymmetric alkynylation.
