Abstract:
Five new nitrogen-containing sorbicillinoids named sorbicillamines A-E (1-5) were isolated from an agitated culture of the deep-sea-derived fungus Penicillium sp. F23-2, which has previously produced indole alkaloids and terpenoids when cultured under static conditions. The structures of 1 to 5, including absolute configurations, were determined based on MS, NMR, and circular dichroism (CD) data. The cytotoxicities of the five new sorbicillin alkaloids against the HeLa, BEL-7402, HEK-293, HCT-116, and P388 cell lines were evaluated.
