Cover Story: Invasive fungal infections still constitute a major health problem, especially when affecting immunocompromised patients. A microbial natural products research program focused on the discovery of new antifungal compounds led to the identification and isolation of TKR 2999 from cultures of the fungus Foliophoma fallens, isolated from Pinus sp. using a dilution to extinction method. The structure of this lipodepsipeptide has been solved by spectroscopic and chemical methods and disclosed more than 20 years after its first report in a Japanese patent. The potent antifungal bioactivity of the molecule against Candida and Aspergillus species, the main pathogens causing fungal infections, has also been confirmed in our studies. Based on our results, Foliophoma has been identified as a genus to be added to the extensive list of fungal genera which are producers of interesting bioactive molecules. Vie
