Metabolite Identification
Common NameIsochaetoglobosin D
DescriptionIsochaetoglobosin D is a member of the cytochalasan chemical class, specifically a metabolite isolated from the fungus Chaetomium globosum. This compound has garnered attention due to its unique structure, which includes a 3,4-substituted pyrrole ring, distinguishing it from other chaetoglobosins. Recent studies have revised its structure based on NMR analysis and biosynthetic considerations, suggesting it aligns more closely with penochalasin C rather than previous classifications (PMID:35517363 ). Isochaetoglobosin D exhibits significant biological activity, demonstrating potent cytotoxicity with an IC50 of 3.5 μM, while other derivatives such as cytoglobosin Ab showed no activity (PMID:28403641 ). The compound's structure has been elucidated through high-resolution mass spectrometry (HR-MS) and NMR data, confirming its classification among the chaetoglobosin family (PMID:27141677 ). Further investigations into its biosynthetic pathway and structural characteristics continue to enhance our understanding of its potential applications in pharmacology and biotechnology (PMID:24418656 , PMID:20225834 ).
