The synthesis and in vitro preclinical profile of a series of 5-heteroaryl substituted analogs of the antipsychotic drug sertindole are presented. Compounds 1-(4-fluorophenyl)-3-(1-methylpiperidin-4-yl)-5-(pyrimidin-5-yl)-1H- indole (Lu AA27122, 3i) and 1-(4-fluorophenyl)-5-(1-methyl-1H-1,2,4-triazol-3- yl)-3-(1-methylpiperidin-4-yl)-1H-indole (3l) were identified as high affinity α1A-adrenoceptor ligands with Ki values of 0.52 and 0.16 nM, respectively, and with a >100-fold selectivity versus dopamine D2 receptors. Compound 3i showed almost equal affinity for α1B- (Ki = 1.9 nM) and α1D- adrenoceptors (Ki = 2.5 nM) as for α1A, as well as moderate affinity for 5-HT1B (Ki = 13 nM) and 5-HT 6 (Ki = 16 nM) receptors, whereas 3l showed >40-fold selectivity toward all other targets tested. Based on in vitro assays for assessment of permeability rates and extent, it is predicted that both compounds enter the brain of rats, non-human primates, as well as humans, and as such are good candidates to be carried forward for further evaluation as positron emission tomography (PET) ligands.

Insomnia affects a growing portion of the adult population in the U.S. Most current therapeutic approaches to insomnia primarily address sleep onset latency. Through the 5-hydroxytryptamine2A (5-HT2A) receptor, serotonin (5-HT) plays a role in the regulation of sleep architecture, and antagonists/ inverse-agonists of 5-HT2A have been shown to enhance slow wave sleep (SWS). We describe here a series of 5-HT2A inverse-agonists that when dosed in rats, both consolidate the stages of NREM sleep, resulting in fewer awakenings, and increase a physiological measure of sleep intensity. These studies resulted in the discovery of 1-[3-(4-bromo-2- methyl-2i/-pyrazol-3-yl)-4-methoxyphenyl]-3-(2,4-difluorophenyl)urea (Nelotanserin), a potent inverse-agonist of 5-HT2A that was advanced into clinical trials for the treatment of insomnia.

, p. 931 - 939 (2007/10/03)
Starting from 1H-pyrazol, a wide number of 1-alkyl-1H-pyrazol-4-yl and 1-alkyl-1H-pyrazol-5-ylboronic acids and their pinacol esters were synthesized and characterized. The key step in the described methodology is the regioselective lithiation of the pyrazole ring. The synthesized pinacolates are stable under prolonged storage and can be used as convenient reagents in organic synthesis.
