چکیده

Earlier studies have shown that Furacinl inhibits the formation of acetyl coenzyme A2 from pyruvate anaerobically (1). Acetone powder preparations of pigeon liver and rat testis were used in the early work. The results suggested that Furacin inhibits reactions mediated by pyruvic oxidase; therefore, further studies were continued with more highly purified preparations of this enzyme from pigeon breast muscle (2). Studies of the effect of Furacin on Reactions 1, 2, and 3 form the basis of this paper. The stoichiometry of these processes has been shown previously by other workers (2, 3).

Effect of furacin on the dissimilation of pyruvate and formate by cell-free extracts of bacteria.

Previously it has been shown that Furacin (5-nitro-2-furaldehyde semicarbazone) inhibited the dismutation of pyruvate by whole resting cells of Micrococcus pyogenes var. aureus (1). Other earlier studies have also shown that both pyruvate dismutation and the formation of acetylmethylcarbinol (AMC) by cell-free extracts of pigeon breast muscle were markedly inhibited by Furacin (2). We are repor...

Metabolism of the nitrofurans. II. Incubation of Furacin with mammalian tissues.

Furacin* (5-nitro-2-furaldehyde semicarbazone) is an antibacterial agent effective against both Gram-negative and Gram-positive organisms (l-3). It has also been studied extensively, along with other nitrofurans, to determine its fate during metabolism in the body (4, 5). Certain of these nitrofurans having chemotherapeutic activity partially withstand metabolic breakdown in the body and are ex...

THE MICRODETERMINATlON OF FORMATE PRODUCED FROM PYRUVATE BY CELL-FREE EXTRACTS OF ESCHERICHIA COLI *

Previous studies had demonstrated that Furacin (5-nitro-2-furaldehyde semicarbazone) inhibited the dismutation of pyruvate as well as its conversion to acetylmethylcarbinol by cell-free extracts of both avian (1) and bacterial (2) cells. It was therefore thought desirable to investigate the effect of this compound on the so called phosphoroclastic dissimilation of pyruvate to acetyl phosphate a...

Metabolism of the nitrofurans. III. Studies with xanthine oxidase in vitro.

For a better understanding of the mechanism of action of the nitrofurans in the mammalian organism, studies of their metabolism have been initiated. Excretion studies (1) have revealed that only a small part of most ingested nitrofurans appears unchanged in the urine. Bender and Paul (2) in preliminary studies have shown that 5-nitro-2-furaldehyde semicarbazone (Furacin’) undergoes degradation ...

The effect of acetate, pyruvate, and glucose on alcohol metabolism.

Although many investigators have studied the effects of pyruvate and glucose on alcohol metabolism, there is still disagreement as to what effect. they have on the rate of alcohol oxidat.ion. Jacobsen (1) discussed t.he various reports in which the results vary from no effect of pyruvate, inhibition by pyruvate or glucose, or an actual increase in the rate of alcohol oxidation by pyruvate or gl...
