Gualamycin, a novel acaricide produced by Streptomyces sp. NK11687. II. Structural elucidation.

A novel acaricide, gualamycin was isolated from the culture broth of Streptomyces sp. NK11687. The structure of gualamycin was determined to be (2R,3S,4S)-2-O-[4-O-(2-amino-2-deoxy-beta-D-gulopyranosyl)-alpha-D - galactopyranosyl]-2,3,4-trihydroxy-4-[(2S,3S,4S,5S)-3,4-dihydroxy-5-hydr oxy - methylpyrrolidin-2-yl] butanoic acid by FAB-MS, 1H and 13C NMR, COSY, HMQC, HMBC, IR, X-ray crystallograp...

SW-163C and E, novel antitumor depsipeptides produced by Streptomyces sp. II. Structure elucidation.

SW-163C and E are novel antitumor antibiotics, which belong to quinomycin family, isolated from the culture broth of Streptomyces sp. SNA15896. These compounds were determined to be cyclic depsipeptides having 3-hydroxyquinaldic acid as a chromophore and a sulfur-containing intramolecular cross linkage through various spectroscopic analyses.

Epostatin, new inhibitor of dipeptidyl peptidase II, produced by streptomyces sp. MJ995-OF5 II. Structure elucidation.

During the course of screening fermentation broths for new inhibitors of dipeptidyl peptidase II (EC 3.4.14.2), we discovered epostatin (C23H33N3O5) from Streptomyces sp. MJ995-OF5. The taxonomy of producing strain, fermentation, isolation, physico-chemical properties and biological properties have been described in the preceding paper1). Herein we report on the structure determination of epost...

EI-2346, a novel interleukin-1beta converting enzyme inhibitor produced by Streptomyces sp. E-2346. II. Structure elucidation.

inflammation3,4). Thus, ICE inhibitors would be useful as anti-inflammatory agents. As described in previous paper5), we isolated novel ICE inhibitory compound, EI-2346, from culture broth of Streptomyces sp. E-2346. In this paper, we describe the structure elucidation of EI-2346. The physico-chemical properties of EI-2346 (1) were summarized in previous paper5). The molecular formula of 1 was ...

Ferroverdins, inhibitors of cholesteryl ester transfer protein produced by Streptomyces sp. WK-5344. II. Structure elucidation.

The structures of ferroverdins B and C, novel inhibitors of cholesteryl ester transfer protein, were elucidated by spectroscopic studies including various NMR measurements. They are the complex between one Fe2+ and three ligands, that is, two common p-vinylphenyl-3-nitroso-4-hydroxybenzoates and one hydroxy p-vinylphenyl-3-nitroso-4-hydroxybenzoate for ferroverdin B and one carboxylic acid p-vi...
