KIF18A-IN-4 is a moderately potent ATP and microtubule (MT) noncompetitive KIF18A inhibitor (IC₅₀=6.16 μM). KIF18A-IN-4 has selectivity against a large panel of mitotic kinesins and kinases, and does not show any direct effects on tubulin assembly. KIF18A-IN-4 exhibits anti-tumor activity^[1].

IC₅₀: 6.16 μM (KIF18A)^[1]

KIF18A-IN-4 (15 μM; 24 hours) induces a phenotype characterized by multipolar spindle arrays emanating from multiple pericentriolar material (PCM) centers in mitotic MDA-MB-157 cells (pH3+)^[1].
KIF18A-IN-4 (0-10 μM; overnight) has an EC₅₀ of 6.35 μM in OVCAR-3 cells by the mitotic index assay^[1].
