yeast growth, as well as in inhibition of thiamin biosynthesis. Given that thiamin biosynthetic enzymes could convert bacimethrin to 2′-methoxythiamin diphosphate (MeOThDP), it is important to evaluate the effect of this coenzyme analogue on thiamindiphosphate (ThDP)-dependent enzymes. The potential functions of MeOThDP were explored on five ThDP-dependent enzymes: the human and Escherichia coli pyruvate

die entsprechenden Triphosphorsäureester III bzw. IV dargestellt und auf Cocarboxylase Wirkung geprüft. DerTriphosphorsäureester des Homothiaminchlorids war ungefähr 4mal weniger wirksam als Cocarboxylase bzw. Thiamin-triphosphorsäureester, derTriphosphorsäureester des 2′-Desmethyl-thiaminchlorids zeigte nur unbedeutende Cocarboxylase-Wirksamkeit. Die Cocarboxylase-Aktivität der genannten drei Verbindungen
