Mechanism of Action

Targets/IC₅₀/Ki	CDK7 (Cell-free assay) 40 nM CDK2 (Cell-free assay) 620 nM CDK9 (Cell-free assay) 1.2 μM CDK1 (Cell-free assay) 1.8 μM
In vitro	A wide range of cancer types are sensitive to CDK7 inhibition by ICEC0942 with GI50 values ranging between 0.2-0.3 µM. ICEC0942 inhibits PolII, CDK1, CDK2 and RB (retinoblastoma) phosphorylation in the MCF7 breast cancer cell line in a time and dose-sependent manner. ICEC0942 inhibits phosphorylation of CDK7 substrates and promotes cell cycle arrest and apoptosis.
In vivo	In xenografts of both breast and colorectal cancers, ICEC0942 has substantial anti-tumor effects. For pharmacokinetics, CD1 male mice are treated intravenously (IV), subcutaneously (SC) or by oral gavage (PO) with 10 mg/kg ICEC0942. In plasma, ICEC0942 levels decline in a bi-phasic manner, indicating rapid distribution into tissues. Following IV administration of ICEC0942 at 10 mg/kg in male CD1 mice Cl(plasma) is calculated at 78 ml.min/kg. Blood/plasma ratio (Bl/Pl) is 1.81. ICEC0942 has a half-life of 1.9 hrs, a moderate half-life in this species. Only a small proportion (13.5%) of ICEC0942 is metabolized after 2 and 4 hour following a single PO administration (100 mg/kg). Comparing exposure (AUCt) after single PO and IV administration at 10 mg/kg, oral bioavailability (F%) is calculated at 30%. Median T_max for PO administration is 2 hours and is unaffected by increasing dose. Over this dose range, Cmax is linearly associated with dose, as is the total exposure over time (AUCt). In tumor-bearing mice, there is appreciable accumulation of ICEC0942 in tumors 6-hours post administration. ICEC0942 levels in tumors lag behind plasma levels.
