Synthesis, characterization and biological activity of Pt(II) complexes with steroidal thiosemicarbazones [PDF]

Journal of the Serbian Chemical Society, 2021
In this work, Pt(II) complexes of previously synthesized steroidal thiosemicarbazones were synthesized and characterized. The ligands and their metal complexes were studied by analytical and spectroscopic data (elemental analysis, IR, 1D-NMR and 2D-NMR ...

Electrochemical Behavior of Some Substituted Thiosemicarbazones and their Reaction Products with Tetracyanoethylene

International Journal of Electrochemical Science, 2008
The electrochemical behavior of substituted thiosemicarbazones has been investigated. It is found that the cyclic voltammetry of all substitutions is different; this can be attributed to the nature of terminal aldehydic group.

Functionalizing Thiosemicarbazones for Covalent Conjugation

Molecules
Thiosemicarbazones (TSCs) with their modular character (thiosemicarbazides + carbonyl compound) allow broad variation of up to four substituents on the main R1R2C=N(1)–NH–C(S)–N(4)R3R4 core and are thus interesting tools for the formation of conjugates ...
