Y. Hayakawa et al., QUINOLIDOMICINS A(1), A(2) AND B(1), NOVEL 60-MEMBERED MACROLIDE ANTIBIOTICS .2. STRUCTURE ELUCIDATION, Journal of antibiotics, 46(10), 1993, pp. 1563-1569
The structures of novel macrolide antibiotics, quinolidomicins A1, A2
and B1, were elucidated as shown in Fig. 1 by NMR spectral analysis in
cluding a variety of two-dimensional techniques. The quinolidomicins p
ossess a novel 60-membered macrolide ring, which is to our knowledge t
he largest among natural products.
