VX-11e 的 IC50 为 48 nM，有效抑制 HT29 细胞的细胞增殖。

VX-11e 在大鼠和小鼠中均表现出良好的口服生物利用度。[1] VX-11e（50 mg/kg，口服）可强烈抑制 pRSK，并减缓携带人黑色素瘤 RPDX 肿瘤的 NSG 小鼠的肿瘤生长。与 BKM120 联合使用时，VX-11e 显着增强对肿瘤生长的抑制作用。 [2]

通过分光光度偶联酶测定来测定化合物对 ERK2 的抑制作用。在此测定中，固定浓度的活化 ERK2 (10 nM) 与不同浓度的化合物在 DMSO (2.5%) 中孵育 10 分钟。 30°C，0.1 mol/L HEPES 缓冲液，pH=7.5，含有 10 mM MgCl2、2.5 mM 磷酸烯醇丙酮酸、200 μM NADH、150 μg/mL 丙酮酸激酶、50 μg/mL 乳酸脱氢酶和 200 μM erktide 肽。添加 65 μM ATP 开始反应。监测 340 nM 处的吸光度损失。

3H-胸苷的掺入用于测量细胞增殖。在使用含有 10% FBS 的 RPMI 1640 生长培养基的 96 孔板中，细胞以每孔 10,000 个细胞的密度铺板。以连续稀释的量添加化合物。细胞和化合物在 37°C 下孵育 48 小时。 48小时后，向每个孔中添加0.4Ci的3H-胸苷，持续8小时，然后将孔放回37℃培养箱中。使用 Tomtec 96 孔细胞收获机收获细胞后，使用 Wallac 1205 BETAPLATE 液体闪烁计数器计算 CPM。

Prior to the therapy experiments, NSG mice are used to expand in vivo human melanoma RPDX tumors. 50 NSG mice (1:10) are implanted with a collection of tumor fragments that were banked from early mouse passages. These tumors are removed once they have reached the protocol's maximum permitted volume (1,000 mm3), digested, and stored as live cells. To be used in the therapy experiments, a smaller portion of this stock is implanted at a 1:5 ratio into NSG mice while the larger portion is kept as a master bank. With PLX4720 200 ppm chemical additive diet at approximately clinical plasma levels, the expansion phase is continuously under drug pressure. The plasma concentrations of PLX4720 (103.7 μg/mL ±3.2 after 7 days) are comparable to the steady-state concentrations observed in patients receiving vemurafenib 960 mg twice daily (130.6 μg/mL±71.78). Animals are randomly assigned to treatment groups when tumors measure 200 mm3 by caliper measurement, and then there is a 3-day ishout phase. Two times per week, caliper measurements are used to determine tumor size. After two weeks of treatment or as needed for animal welfare, mice are sacrificed. When tumor control is achieved as indicated, dosing is extended. In order to extract proteins, tumor tissue is snap-frozen in liquid N2 and preserved in formalin (for FFPE). 4 hours after the final dose, the treatment groups are sacrificed.
