Product Description

CFI400945 is a potent, selective, and orally bioavailable PLK4 (polo-like kinase 4) inhibitor with IC50 value of 2.8 ±1.4 nM and potential antineoplastic activity. CFI-400945 selectively inhibits PLK4, causing apoptosis to be induced and mitosis to be disrupted. Inhibition of PLK4 also stops PLK4-overexpressing tumor cells from proliferating and dividing. Breast cell line and other tumor cell line growth can be markedly inhibited by CFI-400945. PLK4 is specifically inhibited in cells by CFI-400945, but it also exhibits some activity against AURKB, TRKA, TRKB, and Tie2/TEK (of 290 kinases, only 10 demonstrated more than 50% inhibition).

Biological Activity I Assay Protocols (From Reference)

Targets

PLK4 (IC50 = 0.45 nM)

ln Vitro

UF010 primarily inhibits the G1/S transition with an increased G1 cell population and a decreased cell population in the S phase in a dose-dependent manner in cell-cycle analysis using MDA-MB-231 cells. In cell culture medium containing 10% fetal bovine serum, UF010 has a half-life of 15.8 hours[1].

ln Vivo

CFI-400945 is well tolerated in xenograft models of breast cancer, especially those lacking the tumor suppressor PTEN. In a mouse model of colon cancer, CFI-400945 was well tolerated and demonstrated efficacy in inhibiting the growth of HCT116 tumors when administered orally on an intermittent basis. Following oral administration, CFI-400945 is rapidly absorbed, with maximum plasma concentrations (Cmax) for the tested doses (3.75-104 mg/kg) ranging from 0.25 to 11.68 μg/mL. In a clinical setting, CFI-400945 may be useful even in cases of advanced tumors because it has the ability to suppress the growth of various tumor types. Effective dosages of CFI-400945 administered orally to mice result in plasma levels of the drug that are maintained and stay above the growth inhibition GI50 values and the half-maximal inhibition of cellular PLK4 autophosphorylation EC50 value for a 24-hour period. In addition, CFI-400945 exhibits antitumor activity that is dependent on dose. PLK4 kinase activity appears to be completely inhibited rather than partially inhibited in xenograft tumors from mice administered an effective dose of CFI-400945, according to pharmacodynamic analysis.

Enzyme Assay

Using an indirect ELISA detection system, active PLK4 is purified and used to measure PLK4 activity. FRET-based homogeneous assay kits from Invitrogen are used to measure the compound inhibition of PLK1, PLK2, PLK3, AURKA, and AUKB/INCENP. ATP concentrations of 25, 60, and 80 μM are used for PLK1, PLK2, and PLK3, and 20 and 128 μM are used for AURKA and AURKB/INCENP, respectively, in the assays.

Cell Assay

For six hours, HCT116 and A549 cells are exposed to either DMSO or etoposide (10 μM). One hour prior to cell lysis, TSA (0.2 μM), MS-275, and UF010 (2 μM) are added. Western blotting is performed on the whole cell lysates using antibodies to the specified proteins. It is found that PCNA is a loading control.

Animal Protocol

Adult female athymic CD1 nude mice
10 mg/kg
via oral gavage

Additional Infomation

Ocifisertib is a polo-like kinase 4 (PLK4) inhibitor with potential antineoplastic activity. Upon administration, ocifisertib selectively inhibits PLK4, which results in the disruption of mitosis and the induction of apoptosis. PLK4 inhibition also prevents cell division and inhibits proliferation of PLK4-overexpressing tumor cells. PLK4, a member of the polo family of serine/threonine kinases overexpressed in a variety of cancer cell types, plays a crucial role in the regulation of centriole duplication during the cell cycle.
