We describe the identification of a candidate positron emission tomography (PET) imaging agent for the NLRP3 protein. NLRP3 plays a critical role in the immune system and has proven a difficult target for the development of imaging agents due to its low and cell-specific expression profile. A recently described series of pyridazine-based inhibitors, with improved permeability and brain-penetration properties, was used as a starting point for the development of a suitable PET imaging agent.

Introduction: In the present study, we examined the effects of a supplementation with a sensory functional ingredient (FI, D16729, Phodé, France) containing vanillin, furaneol, diacetyl and a mixture of aromatic fatty acids on the behavioural and brain responses of juvenile pigs to acute stress.

Methods: Twenty-four pigs were fed from weaning with a standard granulated feed supplemented with the functional ingredient D16729 (FS animals, = 12) or a control formulation (CT animals, = 12). After a feed transition (10 days after weaning), the effects of FI were investigated on eating behaviour during two-choice feed preference tests.

The discovery of novel imaging agents for positron emission tomography (PET) relies on medicinal chemistry best practices, including a good understanding of molecular and pharmacological properties required for the acquisition of relevant, high-quality images. This short note reviews the characteristics of a series of clinically successful imaging agents, providing guidance for the optimization of such molecular tools. PET imaging plays an important role in staging disease and in helping clinical dose selection, which is critical for the efficient development of drug candidates.

Motivation can critically influence learning and memory. Multiple neural mechanisms regulate motivational states, among which signalling via specific neuropeptides, such as NPY in vertebrates and NPF and its short variant sNPF in invertebrates, plays an essential role. The honey bee () is a privileged model for the study of appetitive learning and memory.

Background: Siponimod (BAF312), a selective S1P/S1P agonist, reduces disability progression in secondary progressive MS. Recent observations suggest it could act via S1P/S1P-dependent anti-inflammatory and pro-myelination effects on CNS-resident cells.

Objective: Generate preclinical evidence confirming siponimod's CNS penetration and activity.
