AB  - Serotonin receptors modulate numerous behavioral and neuropsychological processes.
Therefore, they are the target for the action of many drugs, such as antipsychotics, antidepressants,
antiemetics, migraine remedies, and many others. The 5-HT1A receptors have been involved in the
pathogenesis and treatment of anxiety and depression and represent a promising target for new
drugs with reduced extrapyramidal side effects. In most antidepressants, a piperazine-based structural
motif can be identified as a common moiety. Here we describe the synthesis, pharmacological,
and in silico characterization of a novel arylpiperazines series with excellent 5-HT1A affinity. The
final compounds, 4a, 8a, and 8b, were selected according to predictions of in silico pharmacokinetics,
docking analysis, and molecular dynamics in conjunction with physical properties, and metabolic
stability. The accentuated molecules could serve as a lead compound for developing 5-
HT1A drug-like molecules for depression treatment.

AB  - Monoamine oxidases (MAOs) play a key role in the metabolism of major monoamine neurotransmitters. In particular, the upregulation of MAO-B in Parkinson's disease, Alzheimer's disease and cancer augmented the development of selective MAO-B inhibitors for diagnostic and therapeutic purposes, such as the anti-parkinsonian MAO-B irreversible binder L-deprenyl (Selegiline®). Herein we report on the synthesis of novel fluorinated indanone derivatives for PET imaging of MAO-B in the brain. Out of our series, the derivatives 6, 8, 9 and 13 are amongst the most affine and selective ligands for MAO-B reported so far. For the derivative 6-((3-fluorobenzyl)oxy)-2,3-dihydro-1H-inden-1-one (6) exhibiting an outstanding affinity (Ki MAO-B = 6 nM), an automated copper-mediated radiofluorination starting from the pinacol boronic ester 17 is described. An in vitro screening in different species revealed a MAO-B region-specific accumulation of [18F]6 in rats and piglets in comparison to L-[3H]deprenyl. The pre-clinical in vivo assessment of [18F]6 in mice demonstrated the potential of indanones to readily cross the blood–brain barrier. Nonetheless, parallel in vivo metabolism studies indicated the presence of blood–brain barrier metabolites, thus arguing for further structural modifications. With the matching analytical profiles of the radiometabolite analysis from the in vitro liver microsome studies and the in vivo evaluation, the structure's elucidation of the blood–brain barrier penetrant radiometabolites is possible and will serve as basis for the development of new indanone derivatives suitable for the PET imaging of MAO-B.
