Abstract

Summary. The syntheses of several new 3-and 5-(4-chloro-2-hydroxyphenyl)-5-and-3-(2, 4- dichlorophenyl)-1-alkylpyrazoles are reported. These syntheses started from simple chlorophenols, 2, 4-dichlorobenzaldehyde or ethyl 2, 4-dichlorobenzoate in order to prepare pyrazoles bearing three and four chloro substituents in certain positions. The affinity of these compounds towards the CB 1 type cannabinoids receptors was then evaluated in human ...
