Repurposing Plant-Based Histone Acetyltransferase Inhibitors: A Review of Novel Therapeutic Strategies Against Drug-Resistant Fungal Biofilms.

The rapid emergence of drug-resistant fungal strains necessitates the development of novel therapeutic approaches for battling biofilm-related infections. Biofilms, efflux pumps, and suppression of virulence traits in pathogenic yeasts are governed by epigenetic enzymes, namely, histone acetyltransferases (HATs) and histone deacetylases (HDACs). The review article is focused on the use of histone acetyltransferase inhibitors (HATi), a mechanism-based epidrug that inactivates the regular function of HATs. With an emphasis on specific plant-based HATi and their Structure-Activity Relationship (SAR), the review enumerates the extensive list of anticancer HATi that can be screened for antifungal activities. By repurposing these anticancer HATi, this approach may help generate broad-spectrum antifungal medications that highlight common biological pathways between fungus and cancer, possibly revolutionizing both treatment domains.
