A series of 4-arylthiosemicarbazides substituted at the N1 position with a 5-membered heteroaryl ring was synthesized and evaluated in vitro for T. gondii inhibition proliferation and host cell cytotoxicity. At non-toxic concentrations for the host cells all studied compounds displayed excellent anti-parasitic effects when compared to sulfadiazine, indicating a high selectivity of their anti-T. gondii activity. The differences in bioactivity investigated by DFT calculations suggest that the inhibitory activity of 4-aryl-thiosemicarbazides towards T. gondii proliferation is connected with the electronic structure of the molecule. Further, these compounds were tested as potential antibacterial agents. No growth-inhibiting effect on any of the test microorganisms was observed for all the compounds, even at high concentrations.

The synthesis of new isatin derivatives containing the 1,2,3-thiadiazole ring in the hydrazone fragment was carried out. It was shown that the obtained compounds do not possess a hemolytic effect and do not exhibit cytotoxicity with respect to normalChang liverhuman cell lines.

Novel unknown potentially biologically active 1-(1,2,3-thiadizolylcarbonyl)-4-(1,2,3-thiadiazolyl)-semicarbazides were synthesized by reactions of 1,2,3-thiadiazolylcarboxylic acid hydrazides with 1,2,3- thiadizolylcarbonyl azide in high yields. The structure of the synthesized compounds was studied by NMR and IR spectroscopy and X-ray diffraction analysis.
