Two novel sorbicillinoids combining a bicyclo[2.2.2]octane with a 2-methoxyphenol moiety, named sorbicatechols A (1) and B (2), were isolated from the culture of the Marine sediment-derived fungus Penicillium chrysogenum PJX-17, together with the known protocatechuic acid methyl ester and caffeic acid methyl ester (3). Their structures, including absolute configurations, were assigned by analysis of NMR, MS data, and TDDFT ECD calculations. Compounds 1 and 2 exhibited activities against influenza virus A (H1N1), with IC50 values of 85 and 113 mu M, respectively.
