Investigating Metal and Fluorophore Controlled Intracellular Localization in Noble Metal Thiosemicarbazone Complexes. [PDF]

Chemistry
Same ligand, same dye, different metal: Thiosemicarbazone conjugates of Pt and Pd show distinctly different localization patterns inside mammalian cells. Abstract Transition metal complexes have been widely utilized as cellular imaging tools. To impart organelle specificity, ligand architecture is usually modified to modulate properties like overall ...

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.

Benzoin thiosemicarbazone

Acta Crystallographica Section E Structure Reports Online, 2005
In the title compound, C15H15N3OS, the thio­semicarbazone moiety is planar, with a maximum deviation of 0.0369 (11) A, and has an E configuration. The planar phenyl rings make dihedral angles of 26.56 (9) and 81.20 (5)° with the plane of the thio­semicarbazone moiety. In the mol­ecule, there are two intramolecular interactions of types N—H⋯O and N—H⋯N.

Synthesis, Characterization, Biological Properties, and Sensor Applications of Novel Thiosemicarbazone Derivatives. [PDF]

Biotechnol Appl Biochem
ABSTRACT In this study, novel thiosemicarbazone derivative molecules (5a–j) were synthesized. The characterization of the synthesized molecules was carried out using 1H–, 13C–NMR, FT–IR, and Q–TOF spectroscopic techniques. Then, the inhibitory effect of these compounds was examined for human carbonic anhydrase I and II (hCA I, and II) and ...
