MK1496 is a n orally bioavailable Polo-like kinase 1 (Plk1) inhibitor with potential antineoplastic activity. Polo-like kinase 1 inhibitor MK1496 selectively inhibits Plk1, inducing selective G2/M arrest followed by apoptosis in a variety of tumor cells while causing reversible cell arrest at the G1 and G2 stage without apoptosis in normal cells. Plk1, named after the polo gene of Drosophila melanogaster, is a serine/threonine protein kinase involved in regulating mitotic spindle function in a non-ATP competitive manner.

PIM-1/HDAC-IN-1 (compound 4d) is a potent inhibitor of PIM-1, with an IC 50 of 343.87 nM. It also exhibits strong inhibitory activity and selectivity against HDAC 1 and HDAC 6, with IC 50 values of 63.65 and 62.39 nM, respectively. Furthermore, PIM-1/HDAC-IN-1 demonstrates apoptosis-inducing potential in MCF-7 cell lines, specifically inducing pre-G1 apoptosis and causing cell cycle arrest at the G2/M phase [1].
PIM1-IN-7 (compound 6c) is a powerful inhibitor of PIM-1, effectively suppressing its activity with an IC50 of 0.67 μM. This compound also exhibits significant cytotoxicity against HCT-116 and MCF-7 cells, as demonstrated by their respective IC50 values of 42.9 and 7.68 μM [1].
