The synthesis of two novel series of 1-(4-chlorophenyl)-4-hydroxy-1H-pyrazoles linked to either polysubstituted 1H-pyrazole counterparts through a carbonyl bridge, or to some biologically-active nitrogenous heterocycles by an amide linker, is described. Ten of the newly synthesized compounds were selected by the National Cancer Institute (NCI) in vitro disease-oriented antitumor screening to be evaluated
