General description

N-Ethylthiourea forms adduct with silver halides and their single crystal X-ray structural and spectroscopic characterizations are described.

Application

N-Ethylthiourea was used in the preparation of Re (III) complexes, which are precursors for the new rhenium complexes, potentially useful in nuclear medicine. It was also used in two-step protocol for the first chemoselective cleavage of 2-hydroxy acid amides.

A two-step protocol for the first chemoselective cleavage of 2-hydroxy acid amides has been developed. Mesylation of the model substrate 2-(hydroxypropionylamino)-4-methylpentanoic acid methyl ester (11) followed by treatment with N-ethylthiourea (13) allows cleavage of 2-hydroxy acid amides under smooth conditions.

Complexes of the type [Re(III)L6]X3, with L = thiourea, N-methylthiourea, N-ethylthiourea or N,N'-dimethytlthiourea and X = Cl- or PF6-, were prepared as suitable precursors for the synthesis of new rhenium complexes potentially useful in nuclear medicine. The infrared (IR) spectra

A series of phenylthiourea and ethylthiourea derivatives of daunorubicin and its congeners was prepared by reaction of the 3'-amino group of the antibiotic with phenylisothiocyanate or ethylisothiocyanate. S-Methylation yielded S-methylisothiouromium salts which when reacted with amines resulted in an intramolecular

Syntheses, single crystal X-ray structural and spectroscopic characterizations are described for a variety of adducts of silver halides with thiourea ('tu'), N-ethylthiourea ('ettu' = EtNH.CS.NH(2)) and N,N'-diethylthiourea ('detu' = EtNH.CS.EtNH). This study greatly extends our knowledge of the complex chemistry

Recent studies have indicated that, during the development of pulmonary hypertension (PH), there is a switch from oxidative phosphorylation to glycolysis in the pulmonary endothelium. However, the mechanisms underlying this phenomenon have not been elucidated. Endothelin (ET)-1, an endothelial-derived vasoconstrictor
