Synthesis and cyclisation of 1,4-disubstituted semicarbazides
Natural Product Research, 2010Semicarbazides, besides possessing medicinal properties, also find wide applications in agriculture and industry. We report in this article the synthesis of the four 1,4-disubstituted semicarbazides: 1-cinnamoyl-4-phenyl semicarbazide (1), 1-oleyl-4-phenyl semicarbazides (2), 1,1',1''-tricitryl-4,4',4''-triphenyl semicarbazide (3) and 1-benzoyl-4 ...

Menthone Semicarbazides and Thiosemicarbazides as Anticonvulsant Agents
Medicinal Chemistry, 2010A 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 ...

A New Ferroelectric: Semicarbazide Hydrochloride
Applied Physics Letters, 1972Dielectric measurements on a single crystal of semicarbazide hydrochloride show three maxima at temperatures of −230, 19, and 21 °C. Initial data for the highest peak clearly suggest a ferroelectric-paraelectric transition with a Curie temperature of 21 °C. In the paraelectric region the Curie law is well followed.

Natural occurrence of semicarbazide in heather honey
Food Additives & Contaminants: Part ARegulatory bodies aim to protect consumers from harmful substances. The use of certain antibiotics is prohibited in food-producing animals in the EU due to their potential detrimental effects on humans. Among these are nitrofuran antibiotics, which degrade rapidly so that their metabolites are used as markers in screening for their illegal use. The use

Reaction of 2-polyfluoroacylcyclohexanones with semicarbazides
Russian Chemical Bulletin, 19992-Polyfluoroacylcyclohexanones react with semicarbazide and thiosemicarbazide to give 2-(thio)carbamoyl-3-hydroxy-3-polyfluoroalkyl-3,3a,4,5,6,7-hexahydro-2H-indazoles, one of which was studied by X-ray diffraction.

Teratogenic Effect of Semicarbazide in Wistar Rats
Biology of the Neonate, 2009Five groups of pregnant Wistar rats were injected intraperitoneally with a single dose of semicarbazide (SC) on day 5, 7, 10, 13, or 15 of gestation. The lots in each group received either 50, 75, 100 or 150 mg/kg SC. A sixth group received 17 mg/kg of the drug during the entire course of pregnancy.
