產品描述: CCT251545 是一種有效的口服生物利用型的 WNT 信號抑制劑,在7dF3細胞中的IC50值為5 nM。CCT251545 還可作為選擇性化學探針,探討 CDK8 和 CDK19 在人類疾病中的作用 |
靶點:
CDK8; CDK19; Wnt(in 7dF3 cells):5 nM;Wnt/beta-catenin |
體外研究:
The suppression of the WNT pathway activity by CCT251545 is not unique to a specific cell line, is independent of exogenous WNT pathway stimulation, does not result from destabilization of TCF1 or TCF4, and is not due to interference with the luciferase-based reporter readout. CCT251545 also demonstrates a lack of transporter-mediated efflux and a lack of activity across broad in vitro panels of enzyme, receptor, and ion channel targets |
體內研究:
CCT251545 is a potent small-molecule inhibitor of WNT signaling with good oral pharmacokinetics. We demonstrate inhibition of WNT pathway activity in a solid human tumor xenograft model with evidence for tumor growth inhibition following oral dosing |
細胞實驗:
Cell lines: 7dF3 cells, HEK293 cells, SW480, LS174T, COLO205 human colorectal cancer cells Concentrations: 9.1 μM - 0.068 nM Incubation Time: 2 h, 6 h Method: Taqman Assays. 7dF3 cells are seeded at 20 000 cells/well into 96-well cell culture plates. After overnight incubation the cells are treated with CCT251545 at concentrations ranging from 9.1 μM to 0.068 nM. After 2 or 6 h of incubation, cells are washed with PBS and stored at ?80 ℃. Cells are lysed in Cells-to-cDNA II Cell lysis buffer and transferred to PCR plates. |
動物實驗:
Animal Models: Female NMRI mice, Male Wistar rats Dosages: 0.2 mg/kg, 0.5 mg/kg Administration: IV, Oral gavage |
