摘要

Novel nucleoside antibiotics were isolated from the cultured broth of the strain classified as Streptomyces sp. SANK 62799. The strain produced four novel capuramycin derivatives designated as A-503083 A, B, E and E Their structures were elucidated as 2'-O-carbamoyl derivatives of A-500359 A, B (capuramycin), E and F, respectively. A-503083 A, B, E and F inhibited bacterial phospho-N-acetylmuramyl-pentapeptide-translocase (translocase I: EC 2.7.8.13) with IC50 values of 0.024, 0.038, 0.135 and 17.9 muM, respectively.
