and tested for XOR inhibitoryactivity. Hydroxy substitution in the para‐position of the benzaldehyde component was found to confer high inhibitoryactivities. Acyl hydrazones were generally less potent than thiocarbonyl‐containing Schiff bases. Within the thiosemicarbazone series, chloro and cyano substituents in the para‐position of the thiosemicarbazide unit increased activities further, up to potencies
parasites prompted us to look for new agents. We designed and synthesized a series of new thiazolidin-4-one derivatives through a two-step reaction between 4-substituted thiosemicarbazides with hydroxybenzaldehydes followed by the treatment with ethylbromoacetate; maleic anhydride and dimethyl acetylenedicarboxylate afforded target compounds. The thiazolidin-4-one derivatives were used to assess the
