From submerged cultures of Scytalidium sp. 36-93, ten metabolites were isolated due to their effects on dihydroxynaphthalene (DHN) or DOPA melanin biosynthesis. Four of the compounds, scytalols A (1a), B (1b), C (2) and D (3), are new secondary metabolites

1,8-Dihydroxynaphthalene melanin in Wangiella dermatitidis and Alternaria alternata was titrated in vivo with the oxidants permanganate, hypochlorite, and H2O2. Melanized strains neutralized more oxidant and withstood higher concentrations of permanganate and hypochlorite than albino strains did. H2O2 killing required 1,000-fold

Sporothrix schenckii is a human pathogen that causes sporotrichosis, an important cutaneous mycosis with a worldwide distribution. It produces dark-brown conidia, which infect the host. We found that S. schenckii synthesizes melanin via the 1,8-dihydroxynaphthalene pentaketide pathway. Melanin biosynthesis in
Ectophytic fungi occupy the waxy plant surface, an extreme environment characterized by prolonged desiccation, nutrient limitation, and exposure to solar radiation. The nature of mechanisms that facilitate adaptation to this environment remains unclear. In this study, we sequenced the complete
