Abstract
Four new cyclohexanone derivatives (2-5) and one known analog, (-)-Palitantin (1) were isolated from the EtOAc extract of Penicillium commune, a fungal strain of low-temperature habitats. The structures of 2-5 were determined on the basis of extensive spectroscopic analysis. Furthermore, the absolute configuration of 2 was assigned by electronic circular dichroism (ECD) calculations, whereas that 3-5 were deduced via the CD data. Cytotoxicities of 2-5 against five human carcinoma cell lines (Hela, A549, MCF7, HCT116, T24) were evaluated.
