Discovery of Potent KIFC1 Inhibitors Using a Method of Integrated High-Throughput Synthesis and Screening
KIFC1
(HSET), a member of the kinesin-14 family of motor proteins,
plays an essential role in centrosomal bundling in cancer cells, but
its function is not required for normal diploid cell division. To
explore the potential of KIFC1 as a therapeutic target for human cancers,
a series of potent KIFC1 inhibitors featuring a phenylalanine scaffold
was developed from hits identified through high-throughput screening
(HTS). Optimization of the initial hits combined both design–synthesis–test
cycles and an integrated high-throughput synthesis and biochemical
screening method. An important aspect of this integrated method was
the utilization of DMSO stock solutions of compounds registered in
the corporate compound collection as synthetic reactants. Using this
method, over 1500 compounds selected for structural diversity were
quickly assembled in assay-ready 384-well plates and were directly
tested after the necessary dilutions. Our efforts led to the discovery
of a potent KIFC1 inhibitor, <b>AZ82</b>, which demonstrated
the desired centrosome declustering mode of action in cell studies
