A new indole alkaloid from Cladosporium sp. SCSIO41205

A new indole compound, N-hydroxy-N-(2-(1-hydroxy-2-methoxy-1H-indol-3-yl)ethyl acetamide (1), together with four known compounds, N-(2-(1H-indol-3-yl)ethylacetamide (2), N-acetylamicoumacin C (3), N-(2-phenylethyl)acetamide (4), and (2 R,3S)-1-(4-hydroxyphenyl)butane-2,3-diol (5) were isolated from Cladosporium sp. SCSIO41205. Their structures were established by detailed analysis of the NMR and HR-ESI-MS data.
