Thiosemicarbazone and 4-thiazolidinone derivatives were synthesized in one and two step, respectively, from thiosemicarbazide, in satisfactory yields. Then, the synthesized compounds were submitted to evaluation against host cells infected with Toxoplasma gondii. The present studies showed that thiosemicarbazones 2 and 4-thiazolidinone derivatives 3 were effective against intracellular T. gondii.
We report the synthesis and characterisation of new, highly fluorescent, zinc complexes of bis(thiosemicarbazone) ligands incorporating extended aromatic backbones which are cytotoxic at levels comparable to cisplatin; cellular fluorescence imaging studies suggest these cause cell death by disruption of mitochondria.
Two series of ferrocenyl- and aryl-derived cyclopalladated organosilane thiosemicarbazone complexes were synthesised via C-H bond activation. Selected compounds were evaluated for in vitro antiplasmodial activity against the chloroquine-sensitive (NF54) and chloroquine-resistant (Dd2) strains of the human malaria parasite Plasmodium falciparum. Cyclopalladation of the thiosemicarbazones resulte...
Introduction: Due to the anti-proliferative properties of platinum group-thiosemicarbazone complexes, the production of 191Os-labeled 2-acetyl pyridine 4-N-methylthiosemicarbazone (191Os-APMTS) was investigated. Methods: [191Osmium (T½= 15.4d) was produced via the 190Os(n,γ)191Os nuclear reaction using enriched target irradiated...
Various radiometal complexes have been developed for tumor imaging, especially Ga-68 tracer. In the present study, the development of a radiogallium bis-thiosemicarbazone complex has been reported. [67Ga] acetylacetonate bis(thiosemicarbazone) complex ([67Ga] AATS) was prepared starting [67Ga]Gallium acetate and freshly prepared acetylacetonate bis (thiosemicarbazone) (AATS) in 30 min at 90°...
BACKGROUND The biological properties of thiosemicarbazone have been widely reported. The incorporation of some transition metals such as Fe, Ni and Cu to thiosemicarbazone complexes is known to enhance its biological effects. In this study, we incorporated nickel(II) ions into thiosemicarbazone with N4-substitution groups H3L (H; H3L1, CH3; H3L2, C6H5; H3L3 and C2H5; H3L4) and examined its pote...
There are over 600 million people worldwide covering Asian and Oceanic countries including India have the habit of chewing areca nut as masticator in different forms. Arecoline (C(8)H(13)NO(2)) has been reported as one of the abundant constituents of areca nut. A good number of scientific publications have made Arecoline responsible for oral cancer. Based on observation from clinical situation ...
