In spite of rimonabant's withdrawal from the European market due to its adverse effects, interest in the development of drugs based on CB(1) antagonists is revamping on the basis of the peculiar properties of this class of compounds. In particular, new strategies have been proposed for the treatment of obesity and/or related risk factors through CB(1) antagonists, i.e. by the development of selectively peripherally acting agents or by the identification of neutral CB(1) antagonists. New compounds based on the lead CB(1) antagonist/inverse agonist rimonabant have been synthesized with focus on obtaining neutral CB(1) antagonists. Amongst the new derivatives described in this paper, the mixture of the two enantiomers (±)-5-(4-chlorophenyl)-1-(2,4-dichlorophenyl)-3-(2-cyclohexyl-1-hydroxyethyl)-4-methyl-1H-pyrazole ((±)-5), and compound 5-(4-chlorophenyl)-1-(2,4-dichlorophenyl)-3-[(Z)-2-cyclohexyl-1-fluorovinyl]-4-methyl-1H-pyrazole ((Z)-6), showed interesting pharmacological profiles. According to the preliminary pharmacological evaluation, these novel pyrazole derivatives showed in fact both neutral CB(1) antagonism behaviour and significant in vivo activity towards food intake.
