生物活性

RO4987655 is an orally active and highly selective MEK inhibitor with an IC50 of 5.2 nM for inhibition of MEK1/MEK2.

MEK1

5.2 nM (IC50)

MEK2

5.2 nM (IC50)

体外研究(In Vitro)

RO4987655 potently inhibits mitogen-activated protein kinase signaling pathway activation and tumor cell growth, with an 体外研究 IC50 of 5.2 nM for inhibition of MEK1/2. RO4987655 inhibits proliferation of NCI-H2122 cells in a dose-dependent manner with an IC50 value of 0.0065 μM. RO4987655 at doses ranging from 0.1 to 1.0 μM suppresses pERK1/2 already at 2 h after the start of treatment.

Medlife has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究(In Vivo)

Single-agent oral administration of RO4987655 (CH4987655) results in complete tumor regressions in xenograft models. RO4987655 is rapidly absorbed with a tmax of ~1 h. Exposures are dose proportional from 0.5 to 4 mg. The disposition is biphasic with a terminal t1/2 of ~25 hr. Intersubject variability is low, 9% to 23% for Cmax and 14% to 25% for area-under-the-curve (AUC). pERK inhibition is exposure dependent and is greater than 80% inhibition at higher doses. The pharmacokinetic-pharmacodynamic relationship is characterized by an inhibitory Emax model (Emax ~100%; IC50 40.6 ng/mL) using nonlinear mixed-effect modeling. Female athymic nude mice are randomized into study groups. The tumors size is estimated with digital caliper and PET scans performed on days 0, 1, and 3 with 1.0, 2.5, and 5.0 mg/kg RO4987655. The vehicle treatment does not inhibit the NCI-H2122 tumor xenograft growth over this time frame. In contrast, RO4987655 treatment results in 119% tumor growth inhibition (TGI) at 1.0 mg/kg, 145% TGI at 2.5 mg/kg and 150% TGI at 5.0 mg/kg on day 3. PET imaging shows that [F] FDG uptake in the xenografts decreases within 24 h (day 1) from the administration of RO4987655.

1:一般建议:溶解度为Medlife测试数据,可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异,仅做参考,具体以实验方案为准。

2:储存条件:粉末-20°C一般情况可以保存3年,溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异,请细致阅读产品信息,并辅助参考相关文献描述。
