Abstract:
A new benzophenone derivative, 8'-hydroxymonomethylsulochrin (1), together with eighteen known compounds (2-19) were produced by the endophytic fungus Aspergillus fumigatus WJ-131, isolated from the stem of Gardenia jasminoides. The structure of 1 was determined by extensive spectroscopic analysis and X-ray crystallography. Under the condition of concentration of 20.0 μM, the splenic lymphocytes proliferation rates of compounds 1 and 7 induced by LPS were 39.4% and 38.1% (LPS, the splenic lymphocytes cell proliferation rates of 21.3%), and the splenic lymphocytes proliferation rate of compounds 7 induced by ConA is 44.6% (ConA, the splenic lymphocytes proliferation rates of 28.9%). Therefore, compounds 1 and 7 promoted the proliferation of ConA/LPS-stimulated splenic lymphocytes at 20.0 μM in vitro. In addition, compound 1 showed weak antibacterial activity against Fusarium oxysporum.
