The study examined corrosion inhibition of corrosion inhibition of 5-methyl-2H-imidazol-4-carboxaldehyde and 1H-Indole-3-carboxaldehyde on mild steel in acidic medium using weight loss and Density Functional Theory (DFT) methods. DFT calculations were carried out at B3LYP/6-31+G** level of theory in aqueous medium on the molecular structures to describe electronic parameters. The values of ther...

This work studied the effect of gossypol on the mitochondrial respiratory chain of Yarrowia lipolytica. The compound was shown to inhibit mitochondrial electron transfer and stimulate generation of reactive oxygen species. The inhibition kinetics in oxidation of various substrates (NADH, succinate, α-glycerophosphate and pyruvate + malate) by isolated mitochondria was investigated. Analysis of ...

The inhibition by oxybarbiturates of diphosphopyridine nucleotide (DPN)-linked oxidations in mitochondria was observed some time ago (l-4). Their effect on the associated phosphorylation was subsequently reported (5,6), but it is now apparent that oxybarbiturates do not uncouple oxidative phosphorylation (7) nor do they inhibit dinitrophenol-activated adenosine triphosphatase (7). Amytal inhibi...

Inhibition of photosynthetic electron transport in isolated chloroplasts by lead salts has been demonstrated. Photosystem I activity, as measured by electron transfer from dichlorophenol indophenol to methylviologen, was not reduced by such treatment. However, photosystem II was inhibited by lead salts when electron flow was measured from water to methylviologen and Hill reaction or by chloroph...
