Growth-inhibitory activities of some or all of 98 1,4-naphthoquinones and 16 related compounds on Escherichia coli and two strains of Staphylococcus aureus were determined alone or in combination. These values, when plotted against their polarographic half-wave potentials and those of their C2-n-butylthio analogs support the hypothesis that these compounds, or the products resulting from their reaction with a protein nucleophile, function by short-circuiting one or other of the quinones present in the electron-transport chain.

1. A procedure is described for assaying in vitro the activity of various inhibitors of methane production by rumen micro-organisms.2. Methods of preparation of various inhibitors are described together with attempts to characterize these compounds by determining their physical properties (physical state, density, chromatographic behaviour), their hydrolysis by rumen contents and their relative potency as inhibitors.3. The results of preliminary studies with trichloroethanol and its ester with pivalic acid are given.4. The inhibitory activities of several groups of related compounds are reported. These include the polyhalogenated alcohols and their esters with pivalic acid, the esters of trihalogenated alcohols and monobasic fatty acids from C2to C16and the trihalogenated alcohol esters of dibasic acids. The results of experiments with esters of alcohols and polyhalogenated carboxylic and sulphonic acids are also given.5. It is concluded that the mechanism of action of the inhibitors might be similar to that of known polyhalogenated methane analogues (e.g. chloroform). The relative activity of various compounds might be partly governed by the ease of their absorption into the microbial cells and by the extent to which the esters can be hydrolysed by rumen contents.6. The results show that some substances are very poor inhibitors, unless they are esterified (e.g. trichloroacetic acid) but on the whole the esters in which the polyhalogen grouping is on the alcohol portion of the molecule are better inhibitors than those in which it is on the acid portion of the molecule.

Group 1

1. Certain aromatic polysulphonic acids, previously tested for inhibition of the haemolytic activity of staphylococcal α-toxin, together with some additional related compounds, were tested as possible inhibitors of α-toxin in mice. 2. Compounds that inhibited the haemolytic activity of α-toxin at concentrations of 0·16mm or less [compounds (I), (II), (IV), (V), (VII) and (VIII)] were found to inhibit the lethal effect of α-toxin. 3. With the exception of compound (VIII), amounts of 1mg. were required to inhibit 4 LD50 of toxin when the test compounds were premixed with α-toxin before injection; comparable inhibition with 0·3mg. of compound (VIII) was achieved without prolonged premixing. 4. Mixtures of α-toxin and compounds (I) and (II) containing an excess of test compound showed markedly diminished inhibitory activities. 5. The ‘half-molecule’ analogues of group 1 [compounds (III) and (XVIII)] were non-inhibitory. 6. Compounds (I)–(V), when administered separately from α-toxin by the same route (intraperitoneal), were active only when injected almost simultaneously with toxin, whereas compounds (VII) and (VIII) were strikingly inhibitory when injected 15min. before or after the toxin. 7. Compound (VIII) failed to inhibit the lethal effect of α-toxin when injected by a different route (intravenous).
