1-[3-(4-Bromo-1-methyl-1H-pyrazol-5-yl)-4-methoxyphenyl]-3-(2,4-difluorophenyl)urea Chemical Properties,Usage,Production

Uses

Nelotanserin is a potent selective 5-HT2A inverse agonist, nelotanserin has low nanomolar potency on the 5-HT2A receptor with at least 30- and 5000-fold selectivity compared with 5-HT2C and 5-HT2B receptors.

Definition

ChEBI: Nelotanserin is a member of pyrazoles and a ring assembly.

Synthesis

720702-45-4

59025-55-7

839713-36-9

3-(4-bromo-1-methyl-1H-pyrazol-5-yl)-4-methoxyaniline (16.7 kg) was dissolved in acetonitrile (78.6 kg) in a 200 liter glass jacketed reactor under nitrogen protection. Top stirring was turned on and the internal temperature was controlled within the specified range. Subsequently, 2,4-difluorophenyl isocyanate was slowly added to keep the temperature of the reaction system stable. Upon completion of the reaction, the target product 1-(3-(4-bromo-1-methyl-1H-pyrazol-5-yl)-4-methoxyphenyl)-3-(2,4-difluorophenyl)urea was isolated and purified by appropriate post-treatment steps.

in vivo

Each compound is tested in a minimum of five rats by oral gavage with administration occurring in the middle of the inactive period, 6 h after light onset. The delta power during non-REM sleep (NREMS) is significantly different between all the analogues tested and the vehicle control. Nelotanserin (Compound 39) produces significant increases in delta power that persist for the first 4 h following dosing. Significant differences are found, however, in NREMS bout length. Nelotanserin significantly increases NREMS bout length during the first hour following dosing, and 3 does so during the second hour. In conjunction with this increased NREM bout duration, the number of NREM bouts decrease during the first hour for Nelotanserin (p<0.01) as well as for compound 15 (p<0.05)[2].

IC 50

5-HT2A Receptor: 1.7 nM (IC50); 5-HT2C Receptor: 79 nM (IC50); 5-HT2B Receptor: 791 nM (IC50)
