Bacteria of the genus Streptomyces are used in multiple applications in the medical field owing to their ability to generate large quantities of secondary metabolites. Chromatographic purification of Streptomyces sp. MJM3055 led to the isolation of 1 new streptenol derivative, 1- O-acetylstreptenol A (2), along with (3 E,8 E)-1-hydroxydeca-3,8-dien-5-one (1), streptenol A (3), cyclo-(L-Ile-L-Pro) (4), streptazolin (5), and 7- O-acetylstreptazolin (6). The structures were elucidated by interpretation of combined mass spectrometry, circular dichroism, and 2-dimensional nuclear magnetic resonance spectroscopic data. Among these isolated compounds, compound 1 exhibited strong cytotoxic effects against Jurkat T cells.
