Ys. Bahn et al., YUA001, A NOVEL ALDOSE REDUCTASE INHIBITOR ISOLATED FROM ALKALOPHILICCORYNEBACTERIUM SP. YUA25 - I - TAXONOMY, FERMENTATION, ISOLATION ANDCHARACTERIZATION, Journal of antibiotics, 51(10), 1998, pp. 902-907
YUA001 is a novel aldose reductase inhibitor produced from alkalophili
c Corynebacterium sp. YUA25 isolated from soil. YUA001 was purified fr
om the supernatant of culture broth by successive silica gel column ch
romatography, Sephadex LH20-100 gel column chromatography, and HPLC. F
rom instrumental analysis, molecular formula of YUA001 is C13H19NO2 an
d its molecular weight is 221. It exhibits potent aldose reductase inh
ibition activity and has no antimicrobial activity against some Gram-p
ositive or Gram-negative bacteria, fungi and yeast.
