A new indolinepeptide fromPaecilomyces sp. J300

A new indolinepeptide (3) was isolated, together with two known compounds, a cerebroside (1) and an alloxazine (2), from silkworm larvae infected withPaecilomyces sp. J300. On the basis of spectroscopic data, their structures were elucidated as (4E, 8E, 2S, 2′R, 3R )-N-2′-hydroxy-hexadecanoyl-1-O-β-D-glucopyranosyl-9-methyl-4, 8-sphingadienine (1), 7,8-dimethylalloxazine (2) and 3β,5-dihydroxy-1-N-methyl-indoline-2β-carbonyl amino-D-alanyl-erythro-β-hydoxyiso-leucinyl-glycine (3).
