Pimavanserin is a selective serotonin 2A receptor (5-HT2AR) inverse agonist that has shown promise for treatment of psychotic symptoms in patients with Parkinson's disease. Here, we detail the 11C-labeling and subsequently evaluate pimavanserin as a PET-radioligand in pigs. [11C]Pimavanserin was obtained by N-methylation of an appropriate precursor using [11C]MeOTf in acetone at 60 °C giving radiochemical yields in the range of 1-1.7 GBq (n = 4). In Danish Landrace pigs the radio ligand readily entered the brain and displayed binding in the cortex in accordance with the distribution of 5-HT2ARs. However, this binding could not be blocked by either ketanserin or pimavanserin itself, indicating high nonspecific binding. The lack of displacement by the 5-HT2R antagonist and binding in the thalamus suggests that [11C]pimavanserin is not selective for the 5-HT2AR in pigs.

Nonalcoholic fatty liver disease (NAFLD) is increasingly prevalent worldwide, causing serious liver complications, including nonalcoholic steatohepatitis. Recent findings suggest that peripheral serotonin (5-hydroxytryptamine, 5HT) regulates energy homeostasis, including hepatic lipid metabolism. More specifically, liver-specific 5HT2A knockout mice exhibit alleviated hepatic lipid accumulation and hepatic steatosis. Here, structural modifications of pimavanserin (CNS drug), a 5HT2A antagonist approved for Parkinson's disease, led us to synthesize new peripherally acting 5HT2A antagonists. Among the synthesized compounds, compound 14a showed good in vitro activity, good liver microsomal stability, 5HT subtype selectivity, and no significant inhibition of CYP and hERG. The in vitro and in vivo blood-brain barrier permeability study proved that 14a acts peripherally. Compound 14a decreased the liver weight and hepatic lipid accumulation in high-fat-diet-induced obesity mice. Our study suggests new therapeutic possibilities for peripheral 5HT2A antagonists in NAFLD.
Identification of novel aminopiperidine derivatives for antibacterial activity against Gram-positive bacteria
Lee, Hee-Yeol,An, Kyung-Mi,Jung, Juyoung,Koo, Je-Min,Kim, Jeong-Geun,Yoon, Jong-Min,Lee, Myong-Jae,Jang, Hyeonsoo,Lee, Hong-Sub,Park, Soobong,Kang, Jae-Hoon

We have previously reported amidopiperidine derivatives as a novel peptide deformylase (PDF) inhibitor and evaluated its antibacterial activity against Gram-positive bacteria, but poor pharmacokinetic profiles have resulted in low efficacy in in vivo mouse models. In order to overcome these weaknesses, we newly synthesized aminopiperidine derivatives with remarkable antimicrobial properties and oral bioavailability, and also identified their in vivo efficacy against methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus (VRE) and penicillin-resistant Streptococcus pneumoniae (PRSP).

Azetidine, pyrrolidine and piperidine derivatives
-
, (2008/06/13)
A class of substituted azetidine, pyrrolidine and piperidine derivatives are selective agonists of 5-HT1 -like receptors, being potent agonists of the human 5-HT1Dα receptor subtype whilst possessing at least a 10-fold selective affinity for the 5-HT1Dα receptor subtype relative to the 5-HT1Dβ subtype; they are therefore useful in the treatment and/or prevention of clinical conditions, in particular migraine and associated disorders, for which a subtype-selective agonist of 5-HT1D receptors is indicated, whilst eliciting fewer side-effects, notably adverse cardiovascular events, than those associated with non-subtype-selective 5-HT1D receptor agonists.
