  Synthesis, binding affinity, radiolabeling, and microPET evaluation of 4-(2-substituted-4-substituted)-8-(dialkylamino)-6-methyl-1-substituted-3,4-dihydropyrido[2,3-b]pyrazin-2(1H)-ones as ligands for brain corticotropin-releasing factor type-1 (CRF1) receptors

  摘要：

  Compounds 1-14 were synthesized in a search for high-affinity CRF1 receptor ligands that could be radiolabeled with C-11 or F-18 for use as positron emission tomography (PET) radiotracers. Derivatives of 2 were developed which contained amide N-fluoroalkyl substituents. Compounds [F-18]24 and [F-18]25 were found to have appropriate lipophilicities of logP(7.4) = 2.2 but microPET imaging with [F-18]25 demonstrated limited brain uptake. (C) 2015 Elsevier Ltd.
