The present invention relates to Histone deacetylases 6 (HDAC6) inhibitors and compositions containing the same. Methods of treating diseases and conditions wherein inhibition of HDAC6 provides a benefit, like a cell proliferative disease, an autoimmune or inflammatory disorder, a neurodegenerative disease, a viral disease, malaria, or a combination thereof, also are disclosed.

Eight N-(4-hydroxycarbamoylbenzyl)-1,2,4,9-tetrahydro-3-thia-9-azafluorenes were efficiently prepared as sulfur analogues of Tubastatin A and thus evaluated as new HDAC6 inhibitors. All compounds exhibited potency against HDAC6, and four of them were active in the nanomolar range (IC50 = 1.9–22 nM). Further analysis revealed that the sulfone derivatives (designated as Tubathians) are superior to their non-oxidized sulfide analogues, and the two most active sulfones showed good to excellent HDAC6 selectivity compared to all other HDAC isoform classes.
