    Author: Bai M, Gao CH, Liu K, Zhao LY, Tang ZZ, Liu YH.
    Journal: J Antibiot (Tokyo); 2021 Nov; 74(11):821-824. PubMed ID: 34408287.
    Abstract:
    One new benzophenone derivative, named penibenzophenone C (1), and a new benzophenone natural product, neamed penibenzophenone D (2), together with two known compounds (3, 4) were isolated from the EtOAc extract of the endophytic fungus Penicillium sp. isolated from the mangrove Acanthus ilicifolius L. collected in the South China Sea. The structures of 1-4 were elucidated by extensive NMR spectral interpretation and MS data. The new compounds 1 and 2 showed moderate antibacterial activities against methicillin-resistant Staphylococcus aureus with the MIC values of 3.12 and 6.25 μg ml-1, respectively.
