The mol-ecule of the title compound, C(12)H(15)N(3)O(2)S, which belongs to the family of thio-semicarbazones, containing an acid group, adopts a semi-closed conformation with an intramolecular N-H⋯N hydrogen bond. In the crystal, molecules are linked by strong N-H⋯O and O-H⋯S hydrogen bonds between the acid group and thiosemicarbazone unit, with one additional intermolecular hydrogen C-H⋯O inte...

Reaction of salicylaldehyde thiosemicarbazone (L), 2-hydroxyacetophenone thiosemicarbazone (L) and 2-hydroxynapthaldehyde thiosemicarbazone (L) with [Ru(dmso)4Cl2] affords a family of three dimeric complexes (1), (2) and (3) respectively. Crystal structure of the complex (3) has been determined. In these complexes, each monomeric unit consists of one ruthenium center and two thiosemicarbazone l...

The solid-solid reactions of thiosemicarbazide with 4-formylantipyrine, 2-acetylpyrrole and camphor were performed to afford the thiosemicarbazones 1-3 which underwent hetero-cyclization with phenacyl bromide to furnish the corresponding thiazole derivatives 4-6. The yields of the reactions are quantitative in all cases and the products do not require further purification. A series of 5-arylazo...

We have synthesized a novel series of Schiff bases by condensation of 4-aminoantipyrine and various aromatic aldehydes followed by reaction with thiosemicarbazide. These thiosemicarbazones are potential ligands toward transition metal ions. The reaction of copper(II) salts with 4[N-(benzalidene)amino]antipyrinethiosemicarbazone (BAAPTS), 4[N-(4'-methoxybenzalidene) amino] antipyrinethiosemicarb...

Thiosemicarbazones are a group of compounds that have received comprehensive investigation as anticancer agents. The antitumor activity of the thiosemicarbazone, 3-amino-2-pyridinecarboxaldehyde thiosemicarbazone (3-AP; triapine), has been extensively assessed in more than 20 phase I and II clinical trials. These studies have demonstrated that 3-AP induces methemoglobin (metHb) formation and hy...

Background: Due to interesting tumor imaging properties of bis-thiosemicarbazones, [103Pd]-di-acetyl-bis (N4-methylthiosemicarbazone) ([103Pd] ATSM2) was prepared according to the analogy of radio copper homologues. Materials and Methods: Palladium-103 (T1/2=16.96 d) was produced via the 103Rh (p,n) 103Pd nuclear reaction with proton energy 18 MeV. The final activity was eluted in form of Pd ...

Feulgen and Bersin (1) obtained from the hydrolysis products of the acet>al phospholipide present in muscle a mixture of thiosemicarbazones. They suggested that these thiosemicarbazones are derivatives of pahnitic and stearic aldehydes, although t,hey gave no analytical data supporting this view. Anchel and Waelsch (2) obtained from hydrolysates of lipide mixtures from different tissues, includ...
