Two new compounds from an endophytic fungus Aspergillus sp. HS-05.

Two new compounds, N-[4'-hydroxy-(E)-cinnamoyl]-l-tyrosine methyl ester (1) and methyl 4-methoxy-3-(3'-hydroxy-2'-methyl)propionyloxy-benzoate (2), were isolated from EtOAc extract of the fermentation broth of the endophytic fungus Aspergillus sp. HS-05. Their structures were elucidated by NMR, IR, UV, MS, and CD methods. Compounds 1 and 2 showed no anticancer activities against HL-60 cell lines (both of IC(50)>100 μM) in vitro.
