Biodistribution of 59Fe-thiosemicarbazones

International Journal of Nuclear Medicine and Biology, 1982
The 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 ...

Semicarbazones and thiosemicarbazones, XIII: Study of the hydrolysis of coordinated thiosemicarbazones

Monatshefte f�r Chemie Chemical Monthly, 1991
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.

Formation of ‘Heinz Bodies’ by a Thiosemicarbazone

Nature, 1952
THE marked suppressive action which p-acetyl-amino-benzal-thiosemicarbazone exerts in experimental tuberculosis as first shown by Domagk1, and its effect in certain forms of human tuberculosis as reported by Mertens and Bunge2, make the study of toxic side-effects of this drug an urgent necessity.

Thiosemicarbazones as Aedes aegypti larvicidal

European Journal of Medicinal Chemistry, 2015
A set of aryl- and phenoxymethyl-(thio)semicarbazones were synthetized, characterized and biologically evaluated against the larvae of Aedes aegypti (A. aegypti), the vector responsible for diseases like Dengue and Yellow Fever. (Q)SAR studies were useful for predicting the activities of the compounds not included to create the QSAR model as well as to

Thiosemicarbazones as inhibitors of tyrosinase enzyme

Bioorganic & Medicinal Chemistry Letters, 2017
In the search for compounds which may inhibit the development of melanomas, a series of thiosemicarbazones has been investigated as possible inhibitors of the tyrosinase enzyme. The results showed that all the thiosemicarbazones tested exhibited significant inhibitory effects on the enzyme.

Antimicrobial Properties of Aliphatic Thiosemicarbazones

Journal of Pharmaceutical Sciences, 1964
A series of thiosemicarbazones of saturated and α,β-unsaturated aliphatic aldehydes was prepared and tested in vitro for activity against various bacteria, yeasts, and molds. Antimicrobial potency was found to depend on chain length and was greatly enhanced by the presence of an unsaturated linkage.

Synthesis and anticancer activity of thiosemicarbazones

Bioorganic & Medicinal Chemistry Letters, 2006
Twenty-six thiosemicarbazones (III-1-III-26) were synthesized via three steps starting from hydrazine hydrate and carbon disulfide. The testing of anticancer activity of these compounds in vitro against P-388, A-549, and SGC-7901 shows that compounds III-15 and III-16 possess a higher inhibitory ability for P-388 and SGC-7901.
