CZS-241
CZS-241 is an orally active and selective inhibitor of Polo-like Kinase (PLK) 4 (IC50=2.6 nM). CZS-241 inhibits TRKA with an IC50 value of 2.74 μM. CZS-241 induces apoptosis and arrests cell cycle at S/G2 phase. CZS-241 shows highly potent antiproliferative activity against leukemia cell lines, and exhibits safety against normal cell lines.

CZS-241 inhibits cell proliferation of chronic myeloid leukemia (CML) cell lines K562 and KU-812 with IC50s of 0.096 μM and 0.25 μM, respectively. CZS-241 has little effect on normal cells including HUVECs and L02[1].
CZS-241 (10 μM; 0-120 min) exhibits 31.5 min of half-life t1/2 and 41.8 μL/min/kg of CLint in human liver microsomal[1].
CZS-241 (0.3 μM, 1 μM, 3 μM; 48 h) arrests cell cycle at S/G2 phase, induces apoptosis in K562 CML cells[1].
CZS-241 (0.03-0.3 μM) inhibits the phosphorylation of PLK4, increases the FBXW5 expression level but decreases the SAS-6 expression level in K562 cells[1].

CZS-241 (20 mg/kg/day; p.o.; 21 days) suppresses tumor progression significantly in K562 cells xenograft mouse model[1].
CZS-241 (200 mg/kg; p.o.; single dose) has no obvious signs of toxicity in heart, liver, spleen, lungs, and kidneys of mice, within 7 days of monitoring[1].
