CC-671 is a dual TTK protein kinase/CDC2-like kinase (CLK2) inhibitor with IC₅₀s of 0.005 and 0.006 μM for TTK and CLK2, respectively.

CC-671 (compound 23) is a dual TTK protein kinase/CDC2-like kinase (CLK2) inhibitor with IC₅₀s of 0.005 and 0.006 μM for TTK and CLK2, respectively. HCT-116 cell lysates treated with CC-671 at 3 μM for 1 h demonstrates that only four kinases show cellular binding of 75% or more including CLK2, CAMKK2, PIP4K22, and JNK^[1].

CC-671 (compound 23) demonstrates significant tumor growth inhibition (TGI) ((vehicle -treated/vehicle) ×100%) of 71% at both 10 and 20 mg/kg on a every 3 days (q3d) dosing schedule. The body weight loss (BWL) in the CC-671 treated group (20 mg/kg ) is higher than in the 10 mg/kg group (17% vs 5%)^[1].

The kinase selectivity profile of CC-671 (compound 23) is assessed. The screen is conducted with the concentration of CC-671 held constant at 3 μM. The TTK binding affinity is measured using the kinase binding assays. The kinase binding assays are based on the binding and displacement of a proprietary, Alexa Fluor 647-labeled, ATP-competitive kinase inhibitor scaffold^[1].

Female SCID mice are inoculated subcutaneously with 5×10⁶ Cal-51 cells. Mice with tumors of approximately 125 mm³ are randomized and treated intravenously at various doses and schedules of CC-671 (compound 23) (n=8 to10/group). Tumors are measured twice a week for the duration of the study. The long and short axes of each tumor are measured using a digital caliper in millimeters and the tumor volumes are calculated^[1].
