  • The genetic relationships among six Cordyceps spp. were investigated based on internal transcribed spacer sequences of ribosomal DNA .A portion of the these genes was amplified by PCR. Approximately 590 base pairs were successfully amplified, cloned, sequenced, compared. The nucleotide sequence of the six amplified fragments were aligned by the clustal W program. As a result, Cordyceps militaris shared 87, 96, 98, 90 and 97% sequences homology with Paecilomyces japonica, Paecilomyces sp. J300, Paeciomyces farinosa. Paecilomyces sp. J500 and Cordyceps sinensis, respectively. Paecilomyces japonica also shared 87, 88, 92 and 87% sequence similarity with Paecilomyces sp. J300, Paecilomyces farinosa, Paecilomyces sp. J500 and Cordyceps sinensis, repectively.

  • A new indolinepeptide (3) was isolated, together with two known compounds, a cerebroside (1) and an alloxazine (2), from silkworm larvae infected with Paecilomyces sp. J300. On the basis of spectroscopic data, their structures were elucidated as (4E, 8E, 25, 2'R, 3R )-N-2'-hydroxy-hexadecanoyl-1-O-$\beta$-D-glucopyranosyl-9-methyl-4, 8-sphingadienine (1), 7,8-dimethylalloxazine (2) and 3$\beta$,5-dihydroxy-1-N-methyl-indoline-2$\beta$-carbonyl amino-D-alanyl-erythro-$\beta$-hydoxyiso-leucinyl-glycine (3).

  • Seven ergosterol derivatives (1-7) were isolated from silkworm larvae infected with Paecilomyces sp. J300. On the basis of spectroscopic means, their structures have been elucidated as 3$\beta$,5$\alpha$-dihydroxy-ergosta-7,22-diene (1), 5$\alpha$,6$\alpha$-epoxy-(22E,24R)-ergosta-8(14), 22-diene-3$\beta$,7$\alpha$-diol (2), 5$\alpha$,6$\alpha$-epoxy-(22E,24R)-ergosta-8, 22-diene-3$\beta$,7$\alpha$-diol (3), ergosta-4, 6, 8(14), 22-tetraene-3-one (4), ergosterol (5), ergosterol endoperoxide (6), 3$\beta$,5$\alpha$-dihydroxy-6$\beta$-methoxyergosta-7,22-diene (7). Compounds 3~7 showed moderate cytotoxicity against five tumor cells.
