M. Orita et al., YM-47141 AND YM-47142 NEW ELASTASE INHIBITORS PRODUCED BY FLEXIBACTERSP Q17897 .2. STRUCTURE ELUCIDATION, Journal of antibiotics, 48(12), 1995, pp. 1430-1434
YM-47141 and YM-47142 are new elastase inhibitor produced by Flexibact
er sp. Q17897. These structures were eludicated by MS and NMR spectral
analysis. YM-47141 and YM-47142 were the cyclic peptides containing t
ricarbonyl moiety hydrated on the center carbonyl carbon in DMSO-d(6).
