Preparation of Pyridinium Derivatives of 2,3-Dichloro-5(8?)-Nitro-1,4-Naphthoquinone (open access)

Preparation of Pyridinium Derivatives of 2,3-Dichloro-5(8?)-Nitro-1,4-Naphthoquinone

This paper describes the preparation of pyridine derivatives of 2,3-dichloro-5(8?)-nitro-1,4-naphthoquinone. A method for the nitration of 2,3-dichloro-1,4-naphthoquinone is also described. Certain 4-n-alkyl, 3,4-dialkyl, and 4-cycloalkyl pyridine derivatives are caused to undergo condensation reactions with the nitrated naphthoquinone, giving rise to a series of compounds of the preceding type (X). All of the compounds prepared will be tested for anti-tubercular activity by Parke-Davis and Company.

A Study of the Reduction Products of N-(4-Nitrophenacyl)-4-(1-Hexyl)pyridinium Bromide (open access)

A Study of the Reduction Products of N-(4-Nitrophenacyl)-4-(1-Hexyl)pyridinium Bromide

Because of the structural analogies between these compounds and several other physiologically active compounds, such as chloroamphenicol, 4,4'-diaminodiphenyl sulfone, and 2,2-bis-(p-aminophenyl)-1,1,1-trichloroethane, a more complete study of the reduction products and the sequence of catalytic reduction of N-(4-nitrophenacyl)-4-(1-hexyl)pyridinium bromide was made in this investigation.

The Hydrolysis of α-(Benzenesulfonyl)-Acetophenone (open access)

The Hydrolysis of α-(Benzenesulfonyl)-Acetophenone

In view of the unexpected behavior of α-(benzenesulfonyl)-acetophenone toward hydrolysis and because of the possible physiological importance of its derivatives it was deemed of interest to make a further study of the hydrolysis of this compound. It was decided to study both the acid and basic hydrolysis of this compound. The problem consisted of finding a satisfactory means of analyzing the hydrolysis products, and carrying out the hydrolysis under the different conditions.

Hydantoins as Anticonvulsants. III. 5-Alkoxy- and Aryloxymethyl-5-(2-Thienyl) Hydantoins (open access)

Hydantoins as Anticonvulsants. III. 5-Alkoxy- and Aryloxymethyl-5-(2-Thienyl) Hydantoins

It has been shown in the case of a compound synthesized in this laboratory that substitution of the thienyl group for one of the phenyl groups in diphenyl hydantoin produces a compound with less toxicity and somewhat greater activity. It was considered of interest to carry out an analogous substitution in the series of 5-phenyl-5-alkoxymethylhydantions.

The Synthesis of N-(4-Nitrophenacyl)-4-Alkylpyridinium Halides and Reduction Products (open access)

The Synthesis of N-(4-Nitrophenacyl)-4-Alkylpyridinium Halides and Reduction Products

The synthesis of several N-(4-nitrophenacyl)-4-alkylpyridinium halides and their reduction products, 1-(4-aminophenyl)-2-[1-(4-alkylpiperidyl)]ethanols, was undertaken because of structural analogies between these and other physiologically active compounds, such as chloroamphenicol (I), 4,4'-diaminodiphenyl sulfone (II), and 2,2-bis(p-aminophenyl)-1,1,1-trichloroethane (III).

Barbituric Acids.  VII.  5-alkyl-derivatives of 5-ethoxy-barbituric Acid (open access)

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

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.

The Synthesis of Benzo(d)pyrido(a)-benzimidazole-5,12-quinone (open access)

The Synthesis of Benzo(d)pyrido(a)-benzimidazole-5,12-quinone

The present investigation yielded an orange product upon refluxing 2-butyramido-3-chloro-1,4-naphthoquinone and 2-aminopyridine in ethanol. When this material was purified, by recrystallization from glacial acetic acid, the melting point was 306 [degrees]. This compound has been shown to be benzo(d)pyrido(a)-benzimidazole-5,12-quinone by the present investigation.
