Synthesis of some 1-Substituted-2-Methylnaphthimidazole-4,9-Diones

Synthesis of some 1-Substituted-2-Methylnaphthimidazole-4,9-Diones

Date: August 1957
Creator: Peterson, Harold W.
Description: Imidazole derivatives of 1,4-naphthoquinones are found to have biological activity which interferes with the utilization of vitamin K or of the purines since they have groups common to these two classes of compounds. This thesis shows the preparation of some 1-substituted-naphthimidazole-4,9-diones for possible biological activity.

Hydantoins as Anticonvulsants. VI. 5-Substituted-Alkoxy Derivatives of 5-Phenylhydantoin

Hydantoins as Anticonvulsants. VI. 5-Substituted-Alkoxy Derivatives of 5-Phenylhydantoin

Date: January 1954
Creator: Hoffman, James Rucker
Description: No derivatives of 5-phenylhydantoin with an oxygen atom attached directly in the five position of the hydantoin nucleus have been found in the literature. It was therefore considered of interest to synthesize a series of compounds of this type to determine the effect of the change of the position of the oxygen atom on anticonvulsant activity.

Barbituric Acids.  VII.  5-alkyl-derivatives of 5-ethoxy-barbituric Acid

Barbituric Acids. VII. 5-alkyl-derivatives of 5-ethoxy-barbituric Acid

Date: January 1955
Creator: Hyde, Harold Wayne
Description: A great deal of research has been devoted in recent years to the search for new drugs for the treatment of epilepsy and related convulsive disorders. This emphasis is occasioned by the fact that no one drug is effective for all patients, and also by the fact that the toxicity of a drug varies considerably from one patient to another. Among the most effective drugs are certain members of the hydantoin and barbituric acid series. For some time there has been in progress in this laboratory an investigation of members of these two series in which a hetro atom attached directly to the hetrocyclic nucleus is introduced into the side chain at position five of these two series.

Barbituric Acids.  V.  5-substituted-mercapto Derivatives of 5-isoamylbarbituric Acid

Barbituric Acids. V. 5-substituted-mercapto Derivatives of 5-isoamylbarbituric Acid

Date: August 1952
Creator: Peterson, Paul Eugene
Description: Since no mention has been found in the literature of any 5-substituted mercapto-5-alkyl derivatives of barbituric acid, it was thought to be of interest to prepare a series of compounds containing sulfur attached directly to the barbituric acid nucleus. 5-substituted mercapto-5-isoamylbarbituric acids were chosen as representative of barbituric acids in which the alkyl group has a fairly high molecular weight.

Infrared Studies of Anions of Barbituric Acids

Infrared Studies of Anions of Barbituric Acids

Date: August 1960
Creator: Barnhart, Richard Lee
Description: As long ago as 1881, it was realized that a functional group of atoms in a molecule would cause an absorption band to appear at a particular frequency in the infrared spectrum of the molecule. In more recent years, the concept of characteristic group frequencies has become firmly established and has resulted in the present widespread use of infrared spectroscopy. There appear to have been relatively few studies of infrared absorption of organic acids as compared with their salts.
