生物活性
L-779450 suppressed DNA synthesis and induced apoptosis in hematopoietic FDC-P1 cells transformed to grow in response to either Raf-1 or A-Raf (FD/DeltaRaf-1:ER and FD/DeltaA-Raf:ER), but it displayed less effects on DNA synthesis and apoptosis when the cells were cultured in IL-3. L-779450 was less effective on B-Raf- or MEK1-responsive cells. Treatment with L779450, but not PLX4720, induced strong KSR1/B-Raf binding in A549 and HMCB cells that possess oncogenic Ras proteins, in the Cal12T line that contains an impaired activity B-Raf mutant, and, surprisingly, in A375 melanoma cells that are homozygous for V600E-B-Raf. L779450-induced B-Raf/C-Raf dimerization was not reduced in MEFs expressing the R615H- and C809Y-KSR1 mutants unable to bind B-Raf; whereas B-Raf/C-Raf dimerization was abolished in cells expressing S297A/S392A-KSR1 that exhibits enhanced inhibitor-induced B-Raf binding.

不同实验动物依据体表面积的等效剂量转换表（数据来源于FDA指南）
| 小鼠 | 大鼠 | 兔 | 豚鼠 | 仓鼠 | 狗 |
| 重量 (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
| 体表面积 (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
| Km系数 | 3 | 6 | 12 | 8 | 5 | 20 |
| 动物 A (mg/kg) = 动物 B (mg/kg) × | 动物 B的Km系数 |
| 动物 A的Km系数 |
例如，依据体表面积折算法，将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量，需要将20 mg/kg 乘以小鼠的Km系数（3），再除以大鼠的Km系数（6），得到化合物用于大鼠的等效剂量为10 mg/kg。
