Abstract

A series of 33 novel (thio)urea-containing compounds were initially designed and synthesized as potential ligands for the histamine H4 receptor (H4R). However, only 3 compounds showed a statistically significant affinity towards H4R (Ki<10 μM). Considering the structural analogy of these thioureas to previously described seleno/thiourea compounds with anticancer and/or reversal multidrug resistance action in cancer cells, selected thioureas were evaluated in in vitro cytotoxicity- and cancer multidrug resistance assays. The thiourea derivatives showed a good cytotoxic activity, being the compound 13 d (4-methyl-N-(p-phenylphenyl)-piperazine-1-carbothiamide) the most active (IC50= 11.9 μM). They also enhanced the cytotoxicity of the topoisomerase inhibitors topotecan and doxorubicin in a checkerboard combination assay. Compound 13 d showed the strongest synergistic effect on topotecan activity, whereas 13 c (4-methyl-N-(p-tolyl)-piperazine-1-carbothiamide) was the best in combination with doxorubicin. These results can be a good starting point to design more potent and effective (thio)urea derivatives with anticancer activity.
