The effect of monochloro and dichloro substitution into the ethyl portion on the pyrolysis of ethyl vinyl ether has been studied. This involved four possible monosubstituted derivatives and six disubstituted derivatives. ...

The new 4'- hydroxy and 3'- aldehyde phase- 1 metabolites of butobarbitone and pentobarbitone are fully synthesized for the first time. These metabolites were used to idenfity and quantify the natural metabolites in human ...

The isolation and characterization of two new isoquinoline alkaloids, Dehydropuntarenine and Dehydrosaulatine, obtained during the column chromatography of an alkaloidal fraction from the roots of B. Actinacantha ...

Various authors have considered the Zero-rest-mass equation and the contour integral representation of its solutions. Ferber generalized these equations to supertwistor spaces with 2N odd components so that with N=O we ...

The synthesis of 6- methyl- 2- phenyl- 7H- oxazolo [3,2-b] 1,2,4-Triazine- 7-one (6, R=Ph) and its 2-P- bromophenyl analogue to the two members of a new heterocyclic system is described

Reactions of equemolar amounts of lead (II) nitrate and 2,2'- bipyridine o r l , 10- phenanthroline in aqueous methanolicsolution yield crystals of Pb (bipy)(H O)(NO ) (1) or Pb (phen) (H O) (NO ) (2) respectively. ...

The relationship between aluminium toxicity and iron metabolism was studied. Male rats were exposed to aluminium by daily intraperitoneal injection of 40pmolelkg body weight. After 45 days, aluminium intoxified rats had ...

Vanadium (III) gives a greenish- yellow complex with anthranilic acid in presence of pyridine. The complex is extractable with chloroform and is used for photometric determination of vanadium by measuring the absorbance ...

We have prepared and characterized a few Mn (III) complexes by using a few bidentate and tridentate ligands. Spectra of the manganese (III) ion in a variety of molecular environments are reported. On the basis of solution ...

A significant decrease of hepatic high-Km glucose- phosphorylating enzyme glucokinase (ATP- D- glucose 6- phosphotransferase, EC 2.7. 1.2, GK) and low-Km hexokinases (EC 2.7. 1.1. HK) activities were noticed in liver ...
