  DOTA-tris(OPp ester) as a bifunctional prochelator for the preparation of DOTA–peptide conjugates

  摘要：

  Peptides containing the chelator DOTA have gained importance for molecular imaging and therapy with radionuclides. However, all synthons described for the convergent solid phase synthesis of DOTA-peptide conjugates show windows of stability that are too narrow to allow a clean and convergent deprotection process. The synthesis of the new prochelator DOTA-tris(OPp ester) starting from cyclen is reported. Using this prochelator for the synthesis of several DOTA peptide conjugates revealed that its cleavage-in contrast to the cleavage of DOTA-tris(tBu ester) conjugates-does not require an extended deprotection time, and therefore results in clean and homogenous products.

  Improved syntheses and applicability of different DOTA building blocks for multiply derivatized scaffolds

  摘要：

  DOTA (1,4,7,10-tetraazacyclodocecane-N,N',N",N'''-tetraacetic acid), which forms extremely stable complexes with a large number of metal ions, is one of the most important and most commonly used chelators for in vivo applications such as cancer diagnosis and therapy. However, many of the published synthesis protocols for DOTA derivatives are complicated and give the products in low yields. Here we report improved synthesis routes for tris-tBu-DOTA, tris-benzyl-DOTA, and thiol-DOTA, and also describe the synthesis of the novel compound tris-4-nitro-benzyl-DOTA. In addition, we determined the applicability of the DOTA derivatives tris-tBu-DOTA, thiol-DOTA, tris-benzyl-DOTA, tris-4-nitrobenzyl-DOTA, tris-allyl-DOTA, DOTA-PFP-ester, and DOTA-PNP-ester for multimerization reactions using amino functionalized PAMAM dendrimers of different sizes. Thiol-DOTA was found to be the best compound for efficient reactions with dendritic scaffolds generating highly homogeneous DOTA-multimers. This DOTA derivative could be quantitatively conjugated to a 128-mer dendrimer. (C) 2007 Elsevier Ltd. All rights reserved.
