One new isochromane (pseudoanguillosporin C, 2), seven isochromanones (soudanones A鈥揋, 3鈥?b>9), and six known analogues including 10 and 11 were isolated from a culture of the fungus Cadophora sp. 10-5-2 M, collected from the subterranean 10th level of the Soudan Underground Iron Mine in Minnesota. All of the compounds were tested against a panel of microbial pathogens, and 2, 3, 10, and 11 were found to have activity against Cryptococcus neoformans (MIC = 35, 40, 20, and 30 渭g/mL, respectively). Compound 11 was also active against Candida albicans, with an MIC of 40 渭g/mL.
