Optogenetic stimulation of type i GAD65(+) cells in taste buds activates gustatory neurons and drives appetitive licking behavior in sodium-depleted mice
Pre-clinical characterization of aryloxypyridine amides as histamine H3 receptor antagonists: Identification of candidates for clinical development
The pre-clinical characterization of novel aryloxypyridine amides that are histamine H3 receptor antagonists is described. These compounds are high affinity histamine H3 ligands that penetrate the CNS and occupy the histamine H3 receptor in rat brain. Several compounds were extensively profiled pre-clinically leading to the identification of two compounds suitable for nomination as development candidates
Preclinical Characterization of the FAAH Inhibitor JNJ-42165279
The pre-clinical characterization
of the aryl piperazinyl urea
inhibitor of fatty acid amide hydrolase (FAAH) <b>JNJ-42165279</b> is described. <b>JNJ-42165279</b> covalently inactivates the
FAAH enzyme, but is highly selective with regard to other enzymes,
ion channels, transporters, and receptors. <b>JNJ-42165279</b> exhibited excellent ADME and pharmacodynamic properties as evidenced
by its ability to block FAAH in the brain and periphery of rats and
thereby cause an elevation of the concentrations of anandamide (AEA),
oleoyl ethanolamide (OEA), and palmitoyl ethanolamide (PEA). The compound
was also efficacious in the spinal nerve ligation (SNL) model of neuropathic
pain. The combination of good physical, ADME, and PD properties of <b>JNJ-42165279</b> supported it entering the clinical portfolio
Aryl Piperazinyl Ureas as Inhibitors of Fatty Acid Amide Hydrolase (FAAH) in Rat, Dog, and Primate
A series of aryl piperazinyl ureas that act as covalent
inhibitors
of fatty acid amide hydrolase (FAAH) is described. A potent and selective
(does not inhibit FAAH-2) member of this class, JNJ-40355003, was
found to elevate the plasma levels of three fatty acid amides: anandamide,
oleoyl ethanolamide, and palmitoyl ethanolamide, in the rat, dog,
and cynomolgous monkey. The elevation of the levels of these lipids
in the plasma of monkeys suggests that FAAH-2 may not play a significant
role in regulating plasma levels of fatty acid ethanolamides in primates
