Endocannabinoids are lipid molecules that serve as natural ligands for the cannabinoid receptors CB1 and CB2. They modulate a diverse set of physiological processes such as pain, cognition, appetite, and emotional states, and their levels and functions are tightly regulated by enzymatic biosynthesis and degradation. 2-Arachidonoylglycerol (2-AG) is the most(More)
Endocannabinoids (eCBs) function as retrograde signaling molecules at synapses throughout the brain, regulate axonal growth and guidance during development, and drive adult neurogenesis. There remains a lack of genetic evidence as to the identity of the enzyme(s) responsible for the synthesis of eCBs in the brain. Diacylglycerol lipase-alpha (DAGLalpha) and(More)
Metabotropic glutamate receptor 7 (mGluR7) remains the most elusive of the eight known mGluRs primarily because of the limited availability of tool compounds to interrogate its potential therapeutic utility. The discovery of N,N'-dibenzhydrylethane-1,2-diamine dihydrochloride (AMN082) as the first orally active, brain-penetrable, mGluR7-selective allosteric(More)
5-Hydroxytryptamine (5-HT)(1A) receptors play an important role in multiple cognitive processes, and compelling evidence suggests that 5-HT(1A) antagonists can reverse cognitive impairment. We have examined the therapeutic potential of a potent (K(i) = 1.1 nM), selective (>100-fold), orally bioavailable, silent 5-HT(1A) receptor antagonist (K(B) = 1.3 nM)(More)
The diuretic amiloride has recently proven neuroprotective in models of cerebral ischemia, a property attributable to the drug's inhibition of central acid-sensing ion channels (ASICs). Given that Parkinson's disease (PD), like ischemia, is associated with cerebral lactic acidosis, we tested amiloride in the MPTP-treated mouse, a model of PD also(More)
Biogenic amines such as norepinephrine, dopamine, and serotonin play a well-described role in the treatment of mood disorders and some types of pain. As alpha2A-adrenoceptors regulate the release of these neurotransmitters, we examined the therapeutic potential of BRL 44408, a potent (Ki=8.5 nM) and selective (>50-fold) alpha2A-adrenoceptor antagonist(More)
During the last three decades, a great deal of information has been discovered about chemical neurotransmission. However, the most important processes, namely the complex nature of neuronal circuitry, the "cross talk" between multiple neurotransmitter systems, and the varying effects neurochemicals have at different receptors, are still being explored.(More)
