2-17

则为已知化合物。对其中部分化合物进行了初步的生物活性测试。其中，化合物

对RPMI8226

OCIMY5及MCF-7细胞表现出了中等的抑制活性，化合物

对热应激下的线虫表现出了显著的保护作用。此外，化合物

及

对化脓性链球菌（

Streptococcus pyogenes

）表现出轻度的抑制作用，而化合物

则对肺炎链球菌（

Streptococcus pneumoniae

）表现出轻度的抑制作用。

Abstract

Seventeen compounds (

1-17

) were isolated from the marine fungus

Aspergillus sp

. Their structures were determined by nuclear magnetic resonance (NMR) spectroscopy and mass spectrum (MS). Among them

compound 1 was first found as a naturally occurring compound and the known compounds

2-17

were confirmed via spectrum and literatures. The bioactivities of selected compounds were preliminarily evaluated. The compound 2 exhibited moderate inhibitory activities toward three cancer cells

RPMI8226

OCI-MY5

and MCF-7 cells

and compound

had significant protective effects on prolonging the survival life of

C. elegans

under heat stress. In addition

the compound

and

showed slight inhibition effects against

Streptococcus pyogenes

and meanwhile the compound

possessed slightly inhibitory activity on

Streptococcus pneumoniae
