Hydroxyphenyl thiosemicarbazones as inhibitors of mushroom tyrosinase and antibrowning agents.
Food Chemistry, 2020Tyrosinase is a metalloenzyme involved in o-hydroxylation of monophenols and oxidation of o-diphenols to o-quinones, with formation of brown or black pigments (melanines).

Biodistribution of 59Fe-thiosemicarbazones
International Journal of Nuclear Medicine and Biology, 1982The 59Fe-iron(II) chelates of 2-formylpyridine thiosemicarbazone (I), 5-dimethylamino-2-formylpyridine thiosemicarbazone (II), and 5-hydroxy-2-formylpyridine thiosemicarbazone (III) were prepared and their biodistribution determined in normal rats. Early accumulation of these complexes occurred in the liver, muscle and pelt with lesser amounts in the ...

Journal of Molecular Structure, 2019
In this study, we explore a series of novel potential antiprotozoal S-(−)-limonene-based benzaldehyde thiosemicarbazones were synthesised and their activity effective against the extracellular promastigote form of Leishmania amazonensis examined ...

The hydrolysis of coordinated thiosemicarbazones was studied. It was found that the nickel(II) ion promotes the reaction. Steric and electronic influences were found. The hydrolysis ofATSC in the trigonal bipyramid compounds [M(ATSC)2Cl]Cl [M=Fe(II), Co(II), Ni(II)], is higher with the Ni(II) complex, the compound with the shorterM-N distance.

Synthesis, antibacterial activity and docking studies of substituted quinolone thiosemicarbazones
Phosphorus Sulfur and Silicon and the Related Elements, 2019Fifteen 2-quinolone thiosemicarbazone derivatives of which eleven were new, were synthesized at room temperature. The key intermediate was the quinolone carbaldehyde, from which thiosemicarbazones were formed by the reaction of thiosemicarbazides with ...
