Biological Activity

SR-3029 is a potent CK1δ/CK1ε inhibitor, with IC50s of 44 nM and 260 nM, respectively. SR-3029 is ATP competitive, with Kis of 97 nM for CK1δ/CK1ε. SR-3029 also blocks CDK6/cyclin D3, CDK6/cyclin D1, CDK4/cyclin D3, CDK4/cyclin D1 and FLT3, with IC50s of 427, 428, 368, 576, and 3000 nM, respectively. SR-3029 shows inhibitory effects on A375 cells, with an EC50 of 86 nM.

In vitro, SR-3029 shows less potent activities against MCF7 and T47D breast cancer cells and the MCF10A cell line, which express low amounts of CK1δ.

In vivo: SR-3029 (20 mg/kg daily i.p.) exibits anti-tumor effects in rthotopic MDA-MB-231, MDA-MB-468 (TNBC), SKBR3 and BT474 (HER2+) tumor xenografts with no overt toxicity in mice. SR-3029 (20 mg/kg daily i.p.) also effectively inhibits the growth of tumor in primary patient-derived xenograft (PDX) models. In addition, SR-3029 (20 mg/kg, i.p.) strongly reduces the expression of nuclear β-catenin in tumors of mice.

Cell Experiment
Cell lines Human A375 melanoma cells
Preparation method SR-3029 is dissolved in DMSO.
Human A375 melanoma cells are cultured in DMEM supplemented with 10% fetal bovine serum, 1% penicillin/streptomycin and 1× MEM Non-Essential Amino Acids at 37°C, 5% CO2. To evaluate the anti-proliferative activity of newly synthesized CK1δ/ε inhibitors, each compound (SR-3029) is subjected to MTT assays against A375 melanoma cells and their EC50 values are determined. Briefly, A375 melanoma cells are plated into a 96-well plate and treated with a series of concentrations of each new inhibitor, vehicle (DMSO) or with SR-3029 or SR-1277 (positive controls). MTT assays are performed four days after treatment and data are analyzed using the GraphPad Prism5.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
