[Effect of N-methyl-N-beta-chloroethylhydrazine and its benzaldehydhydrazone on RNA-and protein synthesis as well as metabolism of synchronously growing yeast cells (Saccharomyces cerevisiae) (author's transl)].

N-methyl-N-beta-chloroethylhydrazine and its benzaldehydhydrazone inhibit the influx of [6-3H]-uracil and L-[U-14C]leucin in yeast cells as well as the incorporation in RNA and protein. Experiments with synchronously and asynchronously growing cells showed the N-methyl-N-beta-chloroethylhydrazine essentially influences the dividing phase while the benzaldehydhydrazone is more effective in the growth phase. The effect of these two substances on respiration, glycolysis and the concentration of fructose-1,6-diphosphate, triose phosphate, and adenosine triphosphate is small.
