  Synthesis and evaluation of fructose analogues as inhibitors of the d -fructose transporter GLUT5

  摘要：

  We have examined the specificity and binding-site spatial requirements of the fructose transporter GLUT5. Interaction with a series of fructofuranosides and fructopyranosides suggests that both furanose and pyranose ring forms of D-fructose combine with GLUT5. The epimers of D-fructose all have low affinity for GLUT5 suggesting that the transporter requires all hydroxyls to be in the fructo-configuration. Similarly there is poor tolerance of all allyl derivatives of D-fructose except 6-O-allyl-D-fructo-furanose. Therefore, the C-6 position offers the most suitable position for development of affinity probes and labels for exploring GLUT5 biochemistry. (C) 2000 Elsevier Science Ltd. All rights reserved.

  A combination of DIBAL-H and Cp2ZrCl2 is shown to promote the regioselective cleavage of primary acetates on a broad scope of substrates, ranging from carbohydrates to terpene derivatives, with a high tolerance toward protecting groups and numerous functionalities found in natural products and bioactive compounds. Apart from providing highly valuable building blocks in only two steps from biosourced raw materials, this selective de-O-acetylation should also be strongly helpful to solve selectivity issues in organic synthesis.
• Synthesis and characterization of 6-deoxy-6-fluoro-d-fructose as a potential compound for imaging breast cancer with PET

  FDG-based imaging with positron emission tomography (PET) has been widely used in the detection of cancer, but has not reached its full potential. In breast cancer, the glucose/fructose transporter GLUT2 and the fructose transporter GLUT5 are known to be overexpressed in transformed tissues, implicating that a fructose-based analogue would be a useful target for the improved imaging of breast cancer. We have successfully synthesized the fluorinated fructose compound, 6-deoxy-6-fluoro-D-fructose (6FDF) and examined its potential for transport and accumulation in breast cancer cells. Expression analysis of GLUT isoforms was performed on two GLUT5 expressing breast cancer cell lines using western blotting and immunocytochemistry. Uptake and inhibition studies were undertaken using [14C]- labelled hexoses. Transport inhibition studies showed dose dependent inhibition of fructose transport in both cell lines by the newly synthesized 6-deoxy-6-fluoro-D-fructose (6FDF). Also, near linear uptake over time of [14C]labelled 6FDF was observed in both cell lines. It appears that 6FDF may have great promise for use in in vivo PET imaging of breast cancer. Ongoing work will confirm the efficacy of this compound in imaging in mouse models. (C) 2009 Elsevier Ltd. All rights reserved.
