生物活性
ONO-7475 is a potent and orally active Axl/Mer inhibitor with IC50 values of 0.7 nM and 1.0 nM, respectively. ONO-7475 sensitizes AXL-overexpressing EGFR-mutant NSCLC cells to the EGFR-TKIs, suppresses the emergence and maintenance of tolerant cells. ONO-7475 combines with Osimertinib provides a bright promise for the study of EGFR-mutated non-small cell lung cancer (NSCLC).
Mice fed a diet containing ONO-7475 exhibited significantly longer survival and, interestingly, blocked leukemia cell infiltration in the liver. In summary, ONO-7475 effectively kills acute myeloid leukemia cells in vitro and in vivo by mechanisms that involve disruption of diverse survival and proliferation pathways.

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。
