ABSTRACT
By means of various chromatographic methods such as Sephadex LH-20,ODS,and semi-preparative HPLC,ten compounds were isolated from Streptomyces sp. A1693 and their structures were elucidated on the basis of spectroscopic data and physico-chemical methods. The compounds comprised 5 butenolides,2 diketopiperazines,and 3 antimycin antibiotics. The structures were identified as (5)-5-(11-hydroxymethyloctyl)furan-2(5)-one (1), (5)-5-(11-hydroxy-11-methylheptyl)furan-2(5)-one (2), (5)-5-(11-methyl-12-oxooctyl) furan-2(5)-one (3), (5)-5-(11-hydroxy-11-methyloctyl)furan-2(5)-one (4), (5)-5-(11-hydroxy-12-methyloctyl)furan-2(5)-one(5),cyclo-Phe-Val (6),cyclo-Phe-Ile (7),uranchimycin A (8),uranchimycin B (9),and deisovalerylblastomycin (10). Among them,1 was defined as a new compound. All the compounds didn't show the cytotoxic activity against A549 cell line (IC₅₀>50 mg·L⁻¹).
