The antiviral activity and induction of interferon-like substance by mepacrine (quinacrine, Atabrine) and Acranil in mice, described previuosly, was studied in more detail and compared with tilorone. The serum substance induced by Acranil was characterized as mouse interferon. Acranil, given parenterally, proved to be as strong as tilorone regarding interferon stimulation, in spite of the presence of only one side chain in the Acrainl molecule. Mepacrine was found to be a wealer interferon inducer than either tilorone or Acranil. The mode of interferon induction by Acranil and tilorone (effect of metabolic inhibitors, hyporesponsiveness to repeated doses, correlation between acute toxicity and antiviral activity, failure of effectiveness in chicks and chicken embryo tissue culture) was found comparable. However, the body temperature reactions of mice to the drugs were different: a striking hypothermic effect of tilorone, a lower one of mepacrine and the absence of body temperature depression by Acranil was observed.

2,4-Dinitrophenol, dicoumarol, carbonylcyanide, m-chlorophenyl-hydrazone and pentachlorophenol all depressed aerobic molar growth yields of Streptococcus agalactiae to values equal to, or less than, those supported by substrate level phosphorylation. When the only source of energy was from substrate phosphorylation (anaerobic growth conditions), there was also a severe depression of the molar growth yield by the same four uncoupling agents. These results indicate that the effect of these agents is to uncouple both substrate and oxidative phosphorylation in S. agalactiae. Amytal inhibited glucose utilization, reduced the amount of O(2) used per mole of substrate and reduced the molar cell yield to that supported by substrate phosphorylation. Atebrin inhibited the respiration rate, but final O(2) consumed per mole of substrate was unchanged, and the respiration was coupled to biosynthesis. Rotenone had no effect on respiration, substrate utilization, or on molar growth yields.
