Abstract
A chiral, hybrid bioisostere of the CF 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 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 difluorination of terminal alkenes using an I(I)/I(III) manifold, this underexplored chiral bioisostere shows potential in drug discovery.
摘要
在一系列伏立诺他（Zolinza）类似物中引入了CF和Et基团的手性杂合生物电子等排体（BITE），并相对于其非氟化类似物研究了它们的组蛋白脱乙酰酶（HDAC）抑制行为。这些含有1,2 - 二氟乙烯单元的化合物中有几种对HDAC1的抑制效力大于临床批准药物本身。发现这种趋势具有普遍性，即BITE修饰的HDAC抑制剂的表现明显优于乙基衍生物。通过使用I(I)/I(III)体系对末端烯烃进行直接催化二氟化引入该基团，这种尚未充分探索的手性生物电子等排体在药物发现中显示出潜力。
