Synthese des Lactoflavins (Vitamin B2) und anderer Flavine

Abstract: Die in unserer letzten Abhandlungl) ausgesprochene Auffassung. dass das von uns synthetisierte 6, 7-Dimeth~l-9-[d, 1'-ribityll-isoallosazin mit Lactoflavin bzw. dessen Hauptanteil wahrscheinlich identisch ist, hat sich durch die weitere chemisch-phpikalische untl biologische Untersuchung bestatigt. Durch wiederholtes Umkrystallisieren des synthetischen Praparates konnten die geringfiigigen Schmelzpunktsdifferenzen von 1 bis 2 O, die fruher noch bestanden hatten, behoben werden, nnd die ausgezeichnete TI-irksam… Show more

“…7 The vitamin-G complex as used here refers to the combination of the filtrate factor and riboflavin. Riboflavin was formerly known as "lactoflavin" or "vitamin B2" (Euler, et al, 1935); Kuhn, Gyorgy, and Wagner-Jauregg 1933) or as "vitamin G" (Sherman and Smith, 1931). The filtrate factor is identical witl; the "vitamin B," of Elvehjem and Koehn (1935) and the "chick antipellagric factor" of Ringrose, Norris, and Heuser (1931).…”

“…Several 1-sugar-substituted 2-hydroxybenzimidazoles have been obtained as by-products in the synthesis of flavins. These compounds were obtained by ring closure of JV-sugar-substituted '-carbalkoxy-o-phenylenediamines (194,402,403,404).…”
