  Arylamides hybrids of two high-affinity σ2 receptor ligands as tools for the development of PET radiotracers

  摘要：

  1-Cyclohexy1-4-[3-(5-methoxy-1,2,3,4-tetrahydronaphthalen-1-yl)propyl]piperazine 1 (PB28) and 2-Methoxy-5-methyl-N-[4-(6,7-dimethoxy-3,4-dihydro-1H-isoquinolin-2-yl)butyl]benzamide 2 (RHM-1) represent leads for tumor diagnosis, given their high affinity at sigma(2) receptors. With the purpose of obtaining good candidates for sigma(2) PET tracers development, hybrid structures between 1 and 2 were designed. Excellent sigma(1)/sigma(2) selectivities were reached when 6,7-dimethoxytetrahydroisoquinoline was linked to an o-methoxy substituted arylamide (11a, 12a, 15a). and for these benzamides an intramolecular H-bond in the active conformation at the sigma sites, was hypothesized. However these excellent sigma(2) ligands were accompanied by interaction with P-gp. which may limit their use as sigma(2) receptor PET agents when tumors overexpress P-gp. Compound 15a whose P-gp interaction was just moderate represents an interesting tool for the development of sigma(2) PET tracers useful in tumors overexpressing P-gp. (C) 2011 Elsevier Masson SAS.
