In this work we reported the synthesis and evaluation of anti-Toxoplasma gondii and antimicrobial activities in vitro of three new compound series obtained from ethyl(5-methyl-1-H-imidazole-4-carboxylate): acylthiosemicarbazide analogues 3a-d, 4-thiazolidinone analogues 4a-d and 1,3,4-thiadiazole analogues 5a-d. All synthesized compounds were characterized by IR, 1H, 13C NMR and HRMS. The majority of the tested compounds show excellent anti-T. gondii activity when compared to hydroxyurea and sulfadiazine. In addition it was also shown that most of the compounds in this study have a better performance against intracellular tachyzoites. The results for antimicrobial activity evaluation showed weak antibacterial and antifungal activities for all the tested molecules, when compared with the standard drugs (chloramphenicol and rifampicin for antibacterial activity; nistatin and ketoconazole for antifungal activity).

This paper describes recent results of design, synthesis and pharmacological evaluation of new N-heterocyclic functionalized N-acylhydrazone compounds, belonging to the 2-methyl-imidazolyl-3-acylhydrazone class (4a-e). These compounds were planned by applying the molecular simplification strategy to propose the structural modifications on the previously described functionalized imidazo[1,2-a]pyridine 3-acylhydrazone series (2), which presented an important analgesic profile. This new series (4) was synthesized in order to investigate the possible pharmacophoric contribution of the N-heteroaromatic ring and N-acylhydrazone moieties to the analgesic activity. Compounds 4a-b are the most potent antinociceptive agents from this series. Copyright (C) 2000 Elsevier Science Ltd.
