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.

Food Additives and Contaminants, 2004
Nitrofuran antibiotics were previously used in animal healthcare but are now prohibited. Semicarbazide is a breakdown product of 5-nitrofurazone and protein-bound semicarbazide is used as a marker residue for the illegal use of 5-nitrofurazone. However, the presence of the prohibited semicarbazide has been reported in some food items of animal origin ...

Semicarbazide-sensitive amine oxidase and kidney disease
American Journal of Physiology-Renal Physiology, 2013With better understanding of the molecular mechanisms underpinning chronic kidney disease, the roles of inflammation and fibrosis are becoming increasingly inseparable. The progression of renal disease is characterized by pathomorphological changes that consist of early inflammatory responses followed by tubulointerstitial fibrosis, tubular atrophy ...

Plasma Semicarbazide-Sensitive Amine Oxidase in Stroke
European Neurology, 1999Semicarbazide-sensitive amine oxidase (SSAO) has been suggested to be involved in the development of vascular endothelial damage. The source of the soluble form of SSAO found in the blood serum is unknown. However, it has been speculated that it is secreted from cells within the vascular wall where high activity of the enzyme is found.

1. Mesityl urea has been prepared and used for the successful preparation of mesityl-semicarbazide. 2. A number of aldehydes and ketones have been characterised with mesityl-semicarbozide. 3. An examination has been made of the effect of basicity of certain primary amines on their reactivity with nitrourea. 4.

The embryotoxic and osteolathyrogenic effects of semicarbazide
Toxicology, 1985The osteolathyrogenic agent semicarbazide was assayed for its toxicity and teratogenicity using early embryos of the frog Xenopus laevis. The 96-h LC50 is 1504.20 mg/l while the 96-h EC50 is 76.28 mg/l. Embryo length is altered prior to the onset of other effects indicated by a reduction in stage of development.

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 ...

Semicarbazide‐Functionalized Silicate Nanoparticles for Peptide Ligation
European Journal of Inorganic Chemistry, 2006AbstractMonodisperse silicate nanoparticles have been used for the development of a site‐specific ligation method that enables the control of the biomolecule orientation at the solid–liquid interface. Two types of zeolite nanoparticles were studied: zeolite β, which possesses a Si/Al ratio of 25, and silicalite‐1, which is a fully silicic material ...

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 ...

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
