产品介绍
MSC2530818 是一种有效的、选择性的、可口服的 CDK8 抑制剂,IC50值为2.6 nM。

产品描述

MSC2530818 is an effective, selective and orally available CDK8 inhibitor (IC50: 2.6 nM).

体外活性

MSC2530818 binds to CDK8 and CDK19 with a similar affinity (4 nM). Potent inhibition of phospho-STAT1SER727, an established biomarker of CDK8 activity, in SW620 human colorectal carcinoma cells is also observed (pSTAT1SER727 IC50=8±2 nM). MSC2530818 demonstrates potent inhibition of WNT-dependent transcription in human cancer cell lines that have constitutively activated WNT signaling. For example, MSC2530818 inhibits the reporter-based luciferase readout in several cell lines bearing activating WNT-pathway mutations; LS174T (β-catenin mutant, IC50=32±7 nM), COLO205 (APC mutant, IC50=9±1 nM) and demonstrates inhibition of WNT3a ligand-dependent reporter readout in PA-1 cells (IC50=52±30 nM). Furthermore, MSC2530818 is a low efflux ratio in Caco-2 cells and does not inhibit any cytochrome P450 subtypes.

体内活性

Tumor-bearing mice treated with MSC2530818 shows a reduction in tumor growth with T/C ratios (based on final tumor weights) of 49% and 57%, respectively. MSC2530818 is generally well tolerated, with no effects on mouse body weight in the qd administration schedule and manageable body weight loss. The human clearance and volume of distribution at steady-state are estimated to be low (0.14 L/h/kg) and small (0.48 L/kg), respectively, resulting in a short predicted terminal half-life (2.4 h). Physiologically based pharmacokinetics simulations suggested that human oral bioavailability maybe ≥75% up to a dose level of 500 mg daily.

动物实验

MSC2530818 is assessed in an established SW620 human colorectal cancer xenograft model in female NCr athymic mice. Tumor-bearing mice are treated orally with MSC2530818 (50 mg/kg bid or 100 mg/kg qd) for 16 days. Tumor weights are measured and body weights are monitored [1].
