  Synthesis and in vitro cellular uptake of 11C-labeled 5-aminolevulinic acid derivative to estimate the induced cellular accumulation of protoporphyrin IX

  摘要：

  Protoporphyrin IX (PplX) accumulation induced by exogenous 5-aminolevulinic acid (ALA) in tumors affects the therapeutic efficacy of ALA-based photodynamic and sonodynamic therapies. To develop a new imaging probe to estimate the ALA-induced PpIX accumulation, C-11-labeled ALA analog (4), an ALA-dehydratase inhibitor, was radiosynthesized via C-11-methylation of a Schiff-base-activated precursor in the presence of tetrabutylammonium fluoride, followed by the hydrolysis of ester and imine groups. The cellular uptake of 4 linearly increased with time and was inhibited by ALA and other transporter competitors. Monitoring analog 4 with positron emission tomography might be useful to estimate the ALA-induced PpIX accumulation in tumors. (C) 2013 Elsevier Ltd. All rights reserved.

Moreover, the present invention relates to means for detecting enzymes in form of an array, which comprises any number of probe compounds of the invention which each comprise a different metabolite of interconnected metabolites representing the central pathways in all forms of life. Moreover, the present invention relates to a method for detecting enzymes involving the application of cell extracts or the like to the array of the invention which leads to reproducible enzymatic reactions with the substrates. These specific enzymatic reactions trigger the indicator (e.g. a fluorescence signal) and bind the enzymes to the respective cognate substrates. Moreover, the invention relates to means for isolating enzymes in form of nanoparticles coated with the probe compound of the invention. The immobilisation of the cognate substrates or metabolites on the surface of nanoparticles by means of the probe compounds allows capturing and isolating the respective enzyme, e.g. for subsequent sequencing.
