Abstract

Nine 10-(indol-3-yl)-[13]cytochalasans such as a new chaetoglobosin V (1); two new natural products, prochaetoglobosin III (2) and prochaetoglobosin IIIed (3); six known chaetoglobosins B-D (4–6), F (7), and G (8) and isochaetoglobosin D (9) in addition to two known sterols, 24(R)-5α,8α-epidioxyergosta-6–22-diene-3β-ol (10) and ergosterol (11), were isolated from the fungus Chaetomium elatum ChE01. The structures of these compounds were elucidated by spectroscopic methods. Compounds 1–9 showed cytotoxicity against the human breast cancer (IC50 2.54–21.29 μM) and cholangiocarcinoma cell lines (IC50 3.41–86.95 μM).
