Two highly hydroxylated 1,3-dihydroisobenzofurans, FR198248 (1) and FR202306 (2), were isolated as peptide deformylase (PDF) inhibitors from Aspergillus flavipes. Compounds 1 and 2 inhibited Staphylococus aureus PDF with IC50 values of 3.6 and 2.5 μm, respectively, and also showed antibacterial activity with an MIC value of 25 μg/ml. In contrast, 6-O-methyl derivative 3 of compound 2 was inactive against both PDF and S. aureus.
13830 as a new anti-influenza agents. The structure of FR198248 was elucidated by several spectroscopic experiments as a novel tetrahydroxybenzaldehyde compound. Furthermore, we described the characteristics of FR198248, itsrelatedcompounds and some derivatives.
