Orsellinic acid

Description

Orsellinic acid is a phenolic compound belonging to the class of secondary metabolites known as depsides. Its chemical structure features a resorcinol moiety, which is significant in various biosynthetic pathways. In the fungal species Aspergillus nidulans, orsellinic acid and its derivatives are produced through the activation of the silent ors biosynthetic gene cluster (BGC) upon exposure to algicidal compounds like neotetrafibricin A from Streptomyces mashuensis DSM40221 (PMID:40931664 ). Additionally, the TgPKS1 gene is implicated in the biosynthesis of orsellinic acid, suggesting a complex interplay of polyketide synthases in its production (PMID:39728323 ). Orsellinic acid derivatives have been isolated from the soil-derived fungus Trichocladium asperum, showcasing their potential cytotoxic properties (PMID:39608554 ). Furthermore, orsellinic acid can form heteromeric depsides through condensation with other acids, expanding its role in the synthesis of bioactive compounds (PMID:39479171 ). Overall, orsellinic acid exemplifies the intricate chemistry of fungal metabolites and their biosynthetic pathways, contributing to the diversity of secondary metabolites in nature.
