Antibacterial Ilicicolinic Acids C and D and Ilicicolinal from Neonectria discophora SNB-CN63 Isolated from a Termite Nest

Ilicicolinic acids A, C, and D (1-3) and ilicicolinal (4) were isolated from a fungus isolated from a Nasutitermes corniger nest in French Guiana. The structures of ilicicolinic acids C and D and ilicicolinal were elucidated using 1D and 2D NMR spectroscopic data as well as MS data. Ilicicolinic acids show antibacterial activity in vitro.
