Fluorinated Analogues of the Histone Deacetylase Inhibitor Vorinostat (Zolinza): Validation of a Chiral Hybrid Bioisostere, BITE

ACS Medicinal Chemistry Letters, 10(9):1336–1340.

A chiral, hybrid bioisostere of the CF3 and Et groups (BITE) was installed in a series of vorinostat (Zolinza) analogues, and their histone deacetylase (HDAC) inhibitory behavior was studied relative to that of their nonfluorinated counterparts. Several of these compounds containing the 1,2-difluoroethylene unit showed in vitro potency greater than that of the clinically approved drug itself against HDAC1. This trend was found to be general with the BITE-modified HDAC inhibitors performing significantly better than the ethyl derivatives. Installed by the direct, catalytic vicinal difluorination of terminal alkenes using an I(I)/I(III) manifold, this underexplored chiral bioisostere shows potential in drug discovery.
