Oximidine III, a New Antitumor Antibiotic against Transformed Cells from Pseudomonas sp. II. Structure Elucidation

Abstract

The structure of oximidine III, a new antitumor antibiotic against transformed cells from Pseudomonas sp. QN05727, was determined to be a benzolactone enamide containing an O-methyloxime moiety as shown in Fig. 1 by NMR spectral analysis including a variety of two-dimensional techniques.
