Metabolite Identification
Common NameSolanioic acid
DescriptionSolanioic acid is a degraded steroid belonging to the class of metabolites produced by fungi. This compound has garnered attention due to its antibacterial properties, particularly its activity against methicillin-resistant Staphylococcus aureus (MRSA). It is synthesized by the fungus Rhizoctonia solani, which was isolated from the medicinal plant Cyperus rotundus. Studies utilizing stable isotope feeding have elucidated the biogenesis of solanioic acid, revealing a steroid 5(6→7)abeo ring contraction mechanism that involves cleavage of the C-5/C-6 bond. Additionally, 9-epi-solanioic acid, a precursor that spontaneously converts to solanioic acid, was also identified in cultures, suggesting it may be the actual natural product. The structural characterization of solanioic acid has been achieved through detailed NMR analysis, single crystal X-ray diffraction, and Mosher ester analysis, providing insights into its unique carbon skeleton and potential applications in antibiotic development. The findings highlight the significance of solanioic acid as a promising candidate in the search for novel antibacterial agents derived from natural sources (PMIDs: 30635614, 25860081).
