Chimeric Pyridone Alkaloids from the Mangrove Endophytic Fungus Aspergillus niger

Thirty-four chimeric pyridone alkaloids, including twenty-eight new compounds named aspernigrins F1−F8, G1−G5, H1−H7, and I−P (1−28), were isolated from the mangrove endophytic fungus Aspergillus niger H6a, together with six known ones (29−34). The structures of these compounds were elucidated by HRESIMS, NMR spectro...
