Thiamine, thiaminepyrophosphate and 4-methyl-5-beta-oxyethylthiazole are studied for their effect on the acetylcholinesterase activity in the brain, blood plasma and cells. The activity of acetylcholinesterase in blood cells is shown to be inhibited most of all by thiamine and thiazole. Acetylcholinesterase

Amiloride (Am) inhibits growth in the fission yeast Schizosaccharomyces pombe. We show that the toxic effect of this drug is relieved by low concentrations of thiamine (Th) and that the pyrimidine moiety of the Th molecule is responsible for growth

The transport of thiamine and 4-methyl-5-hydroxyethylthiazole (MHET), its thiazole moiety, was studied using whole cells of Salmonella typhimurium. It was found that the bacteria possessed an active transport system for thiamine that had Km 0.21 microM and Vmax 33 nmol.min-1.(mg

The thiamine requirement for growth of Eikenella corrodens was investigated. Autoclaved thiamine at a concentration of 1.0 microgram/ml supported maximal growth whereas for the same growth, filter-sterilized thiamine was required at 50-100 micrograms/ml.
