Dihydrochlamydocin is a cyclic tetrapeptide that inhibits histone deacetylases (HDACs).
Details
Dihydrochlamydocin is a cyclic tetrapeptide fungal metabolite structurally related to chlamydocin and HC-toxin. Conformational studies reveal a constrained bis-β-turn backbone that supports its bioactive configuration. It acts as a histone deacetylase (HDAC) inhibitor, modulating chromatin acetylation and affecting transcriptional regulation. Due to its epigenetic activity, dihydrochlamydocin is used as a chemical probe in studies of chromatin biology and cancer-related gene expression.
