Estimation of thiosemicarbazide with chloramine-T

Talanta, 1970
A rapid and accurate method for the estimation of thiosemicarbazide in aqueous solution has been developed based on its oxidation with chloramine-T at room temperature and pH 4. The effect of such variables as pH, mode of addition of reagents and concentration of chloride ion on the extent of oxidation has been studied.

The binding of thiosemicarbazide to collagen in vitro

Archives of Biochemistry and Biophysics, 1969
Abstract The in vitro reaction of ichthyocol and rat skin collagen with thiosemicarbazide was investigated. The aldehydes present in collagen react with thiosemicarbazide to form both saturated and α-β unsaturated aldehyde thiosemicarbazones. Upon dialysis the simple aldehyde derivative is lost and the α-β unsaturated thiosemicarbazone remains on the

Tin(IV) Complexes with Thiosemicarbazide and 4‐Methyl‐3‐thiosemicarbazide Derivatives

Zeitschrift für anorganische und allgemeine Chemie, 2007
AbstractFive new complexes were isolated from a CH2Cl2 solution of SnCl4 and the ligands benzil bis(thiosemicarbazone) L1H6, benzil bis(4‐methyl‐3‐thiosemicarbazone) L1Me2H4, 5‐methoxy‐5,6‐diphenyl‐4,5‐dihydro‐2H‐[1,2,4]‐triazine‐3‐thione, L2H2OMe and 5‐methoxy‐4‐methyl‐5,6‐diphenyl‐4,5‐dihydro‐2H‐[1,2,4]‐triazine‐3‐thione, L2MeHOMe.

Hydrogen bonding in thiosemicarbazide

Acta Crystallographica Section B Structural Crystallography and Crystal Chemistry, 1970
In a recent paper (Domiano, Fava Gasparri, Nardelli & Sgarabotto, 1969, DGNS) the crystal-structure analysis of thiosemicarbazide, carried out by photographic methods, was reported (final R=9 .9%) . The positions of the hydrogen atoms were postulated from consideration of the hybridization of the nitrogen atoms and the packing interactions, no direct ...

A reinvestigation of the cyclodesulfurization of thiosemicarbazides

Journal of Heterocyclic Chemistry, 1981
AbstractA recent report describing the preparation of 2‐(substituted‐amino)‐3,4‐dihydro‐5H‐1,3,4‐benzotriazepin‐5‐ones (3), by the cyclodesulfurization of hydrazides prepared from o‐aminobenzoylhydrazine (1) and isothiocyanates, is erroneus. The products resulting from this reaction sequence are, instead, 2‐(substituted‐amino)‐5‐(o‐aminophenyl)‐1,3,4 ...

Susceptibility to audiogenic seizure induced by thiosemicarbazide

Experimental Neurology, 1969
Abstract Rats, cats, and monkeys were subjected to audiogenic stimuli after the administration of thiosemicarbazide (TSC). The treated rats responded to audiogenic stimulation with episodic running behavior (ERB) with or without convulsion (C), the most effective dosage being 4.4 mg/kg.

Menthone Semicarbazides and Thiosemicarbazides as Anticonvulsant Agents

Medicinal Chemistry, 2010
A series of novel (+/-) 3-menthone semi carbazides (1-7) and thiosemicarbazides synthesized using an appropriate synthetic route and characterized by thin layer chromatography and spectral analysis. The anticonvulsant activity of synthesized compounds was established after intraperitoneal administration in three seizure models in mice which include ...
