Synthesis of conjugated spermine derivatives with 7-nitrobenzoxadiazole (NBD), rhodamine and bodipy as new fluorescent probes for the polyamine transport system
摘要:
The synthesis of a series of conjugated spermine derivatives with benzoxadiazole, phenylxanthene or bodipy fluorophores is described. These fluorescent probes were used to identify the activity of the polyamine transport system (PTS). N-1-Methylspermine NBD conjugate 5 proved to have the optimal fluorescence characteristics and was used to show a selectivity for PTS-proficient CHO versus PTS-deficient CHO-MG cells. It can therefore be used as a tool for the selection of cells sensitive to cytotoxic compounds vectored through the PTS. (c) 2009 Elsevier Ltd. All rights reserved.

The invention relates to novel fluorescent derivatives of polyamines having a benzoxadiazole group, to a method for preparing the same and to the use thereof as diagnosis tools for emphasising the polyamine transport system in cancerous cells in order to adapt the treatment thereof, and thus for selecting patients carrying such tumours in order to adapt their treatment. The derivatives are of the formula (I) or a pharmaceutically acceptable salt thereof, in which: R
1
is one or more NO
2
groups in position 4 or 6, or a SO
