Fatty acid amide hydrolase (FAAH, EC 3.5.1.99) is the main enzyme catabolizing endocannabinoid fatty acid amides. FAAH inactivation promotes beneficial effects upon pain and anxiety without the side effects accompanying agonists of type-1 cannabinoid receptors. Aiming at discovering new selective FAAH inhibitors, we developed a series of compounds (5a-u)(More)
Antagonism of the A2A adenosine function has proved beneficial in the treatment of Parkinson's disease, in that it increases L-dopa therapeutical effects without concomitant worsening of its side-effects. In this paper we describe a preferential A2A adenosine antagonist, ST 1535, with long-lasting pharmacodynamic effects. It competitively antagonizes the(More)
Two types of adenosine receptor ligands were designed, i.e., 9H-purine and 1H-imidazo[4,5-c]pyridines, to obtain selective A(2A) antagonists, and we report here their synthesis and binding affinities for the four adenosine receptor subtypes A(1), A(2A), A(2B) and A(3). The design was carried out on the basis of the molecular modeling of a number of potent(More)
Recently we reported the pharmacological characterization of the 9,10-dihydropyrrolo[1,3]benzothiazepine derivative (S)-(+)-8 as a novel atypical antipsychotic agent. This compound had an optimum pK(i) 5-HT(2A)/D(2) ratio of 1.21 (pK(i) 5-HT(2A) = 8.83; pK(i) D(2) = 7.79). The lower D(2) receptor affinity of (S)-(+)-8 compared to its enantiomer was(More)
ST2472 was shown to bind to multiple receptors, thus resembling the affinity spectrum of atypical antipsychotics. The present study investigates its in-vivo potential antipsychotic effects. ST2472 is effective in the conditioned avoidance response (CAR) test in rats (ED50=1.5 mg/kg p.o.), a model sensitive to antipsychotics. It antagonizes(More)
A series of oxime carbamates have been identified as potent inhibitors of fatty acid amide hydrolase (FAAH), an important regulatory enzyme of the endocannabinoid signaling system. Kinetic analysis indicates that they behave as non-competitive, reversible inhibitors, and show remarkable selectivity for FAAH over the other components of the endocannabinoid(More)
5-HT(6) receptor is one of the most recently cloned serotonin receptors, and it might play important roles in Alzheimer's disease, depression, and learning and memory disorders. Availability of only very few 5-HT(6) receptor agonists, however, does not allow examining their contribution in psychopharmacological processes. Therefore, a new 5-HT(6) receptor(More)
Using rational drug design to develop atypical antipsychotic drug candidates, we generated novel and metabolically stable pyrrolobenzazepines with an optimized pK(i) 5-HT(2A)/D(2) ratio. 5a, obtained by a new palladium-catalyzed three-step synthesis, was selected for further pharmacological and biochemical investigations and showed atypical antipsychotic(More)
