ABSTRACT

A family of new secondary metabolites with a carbazole moiety and an alkyl side chain was isolated from Tsukamurella pseudospumae strain Acta 1857. They were named lipocarbazoles in accordance with their chemical structures, which were determined by mass spectrometry and NMR spectroscopy. Lipocarbazoles are free radical scavengers showing antioxidative activity.
