Fluorinated Analogues of the Histone Deacetylase Inhibitor
Vorinostat (Zolinza): Validation of a Chiral Hybrid Bioisostere, BITE
Posted on 2019-07-22 - 21:13
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.
