Ramanspektren und Normalkoordinatenanalysen von Thioacetamid und Thioacetamid-S-oxid

Spectrochimica Acta Part A: Molecular Spectroscopy, 1974
Abstract The Laser Raman spectra of CH3CSNH2, CH3CSND2, CD3CSNH2, CD3CSND2, CH3CSONH2, CH3CSOND2, CD3CSONH2, and CD3CSOND2 have been measured in the solid state. A normal coordinate analysis has been carried out for the mentioned compounds using the Wilson GF matrix method. The Urey—Bradley-force field has been used in calculating the

Thioacetamide Research in Dogs

Scandinavian Journal of Gastroenterology, 1968
Thioacetamide toxicity in dogs has been studied. A dose of 25 mg/kg on alternate days will produce hepatic necrosis usually of the portal type, within twenty to thirty days. Six of the nine animals receiving this dose died in the stage of necrosis.

The Urease-Catalyzed Hydrolysis of Thiourea and Thioacetamide

Archives of Biochemistry and Biophysics, 1998
Jack bean urease catalyzes the hydrolysis of thiourea with a second-order rate constant (kcat/Km) of 1.6 (+/- 0.2) x 10(-3) M-1 S-1 at pH7, 25 degrees C. This value is lower than that for urea by a factor of 3 x 10(8). The corresponding substitution of S for O in acetamide reduces the kcat/Km value by only a factor of 33. This greater reactivity of the

Hepatocellular Regeneration: Key to Thioacetamide Autoprotection

Pharmacology & Toxicology, 1995
Abstract:Low doses of thioacetamide stimulate cell division and tissue repair in the liver. The objective of this study was to develop an autoprotection model for thioacetamide and investigate if a low dose of thioacetamide (50 mg/kg orally) protects against lethality of a subsequently administered lethal dose (400 mg/kg orally) of the same compound ...

The influence of thioacetamide on the excretion of mercury in rats

Toxicology and Applied Pharmacology, 1971
Abstract The mobilizing effect of thioacetomide (TAA) on deposits of mercury in the kidneys of rats was studied. Following single iv doses of mercuric chloride (HgCl 2 ) containing 0.2, 0.6, and 1.2 mg/kg of mercury, iv doses of 50 mg/kg of TAA were given 1–7 days later and continued for periods of 3–8 days.

Determination of thioacetamide by oxidation with chloramine-T

Talanta, 1966
Chloramine-T oxidises thioacetamide quantitatively in an alkaline medium in the hot, converting the entire sulphur into sulphate. A back-titration method, making use of this oxidation reaction, has been suggested for the determination of thioacetamide.

Mutagenic effects of thioacetamide in Drosophila melanogaster

Mutation Research/Genetic Toxicology, 1978
Thioacetamide, which is carcinogenic in mice and rats, has been reported as negative in Ames's test on Salmonella his- with and without liver microsomal fraction (S 9 mix). Tests on Drosophila reported here showed a significant increase in sex-linked recessive lethals after treatment with thioacetamide, both after injection and after feeding of males.

Karyometric Studies of Thioacetamide-induced Hepatomas

Beiträge zur Pathologie, 1974
Summary In thioacetamide-induced hepatomas the DNA-content decreases to diploidy without changes in the toxic swelling of the nucleus. The principle of multiplication of the nuclear volume by its (dys)functional edema also comes true in regenerative processes following partial hepatectomy.

Energetic processing of thioacetamide in cryogenic matrices

The Journal of Chemical Physics
There is an ongoing debate on the apparent depletion of sulfur in the interstellar medium (ISM) compared to its universal abundance; therefore, the investigation of sulfurous compounds at low temperatures is of utmost importance. This work aims to study thioacetamide, H3C–C(=S)–NH2, in low-temperature inert Ar and para-H2 matrices by IR spectroscopy ...

The influence of thioacetamide on tissue culture cells

Experimental Cell Research, 1961
Abstract Prolonged feeding of thioacctamide to rats induces cancer of the liver, preceded by morphological and respiratory alterations in the liver cells. Tissue culture techniques offer an ideal tool for studying the influence of thioacetamide on the isolated modified hepatic cell, HLM, and the strain L fibroblast, clone 929, both of which are ...
