Description
Tubacin is a histone deacetylase 6 (HDAC6) inhibitor that prevents α-tubulin deacetylation and displays anticancer activity. In cellular models of multiple myeloma and acute lymphoblastic leukemia, inhibition of HDAC6 inhibits cell motility and induces accumulation of ubiquitinated proteins, inducing apoptosis. Tubacin’s inhibitory action on HDAC also downregulates EGFR levels in a mutant renal epithelial cell line, indicating potential benefit as a treatment for polycystic kidney disease.
