Sj. Gould et Cr. Melville, KINAMYCIN BIOSYNTHESIS - SYNTHESIS, DETECTION, AND INCORPORATION OF KINOBSCURINONE, A BENZOL[B]FLUORENONE, Bioorganic & medicinal chemistry letters, 5(1), 1995, pp. 51-54
The kinamycin antibiotics, derived from a benz[a]anthraquinone precurs
or, were recently shown to be 5-diazobenzo[b]fluorene quinones. A 5-ke
tobenzo[b]fluorene quinone has been synthesized and shown to be presen
t in Streptomyces murayamaensis fermentations, and a deuterium-labeled
sample of this metabolite, kinobscurinone, has been incorporated bios
ynthetically into kinamycins C and D.
