As part of our efforts to develop agents for CNS diseases, we have been focused on the 5-HT(6) receptor in order to identify potent and selective ligands for cognitive enhancement. Herein we report the identification of a novel series of 5-piperazinyl-3-sulfonylindazoles as potent and selective 5-HT(6) antagonists. The synthesis, SA R, and pharmacokinetic and pharmacological activities of some of the compounds including 3-(naphthalen-1-ylsulfonyl)-5-(piperazin-l-yl)-1H-indazole (WAY-255315 or SAM-315) will be described.

A Modest Increase in 11C-PK11195-Positron Emission Tomography TSPO Binding in Depression Is Not Associated With Serum C-Reactive Protein or Body Mass Index

Summary: In patients with depression, there is a significant increase in TSPO binding in the anterior cingulate cortex, and depressed patients with low CRP levels show significantly higher TSPO binding compared to controls. However, there is no significant correlation between brain TSPO binding and blood CRP concentration or body mass index.

The novel persistent sodium current inhibitor PRAX-562 has potent anticonvulsant activity with improved protective index relative to standard of care sodium channel blockers

Kristopher M. Kahlig, Liam Scott, Robert J. Hatch, Andrew Griffin, Gabriel Martinez Botella, Zoe A. Hughes, Marion Wittmann

Summary: This study investigated the effects of PRAX-562 on sodium current, neuronal excitability, and protection from evoked seizures. PRAX-562 demonstrated potent inhibition of persistent sodium current and significantly improved tolerability compared to standard sodium channel blockers. It showed robust preclinical anticonvulsant activity and potentially represents a differentiated therapeutic option for hyperexcitability disorders.

Translational Pharmacology of PRAX-944, a Novel T-Type Calcium Channel Blocker in Development for the Treatment of Essential Tremor

Summary: This study assessed the pharmacologic activity and tolerability of the T-type calcium channel blocker PRAX-944 in a rat tremor model and healthy participants. The results showed that PRAX-944 reduced tremor and sigma power in rats, and similar reductions in sigma power were observed in healthy participants. These findings suggest that PRAX-944 holds promise for reducing tremor in patients with essential tremor.
