生物活性
BI01383298是一种有效的,选择性的柠檬酸钠协同转运蛋白 (SLC13A5) 抑制剂。BI01383298, has been shown as a highly potent inhibitor of human NaCT with an IC50 of 25–60 nM, significantly more potent than PF-06649298 (IC50, 0.4–10 μM). BI01383298 is a high-affinity inhibitor selective for human NaCT with no effect on mouse NaCT. The inhibition of human NaCT by BI01383298 is evident for the constitutively expressed transporter in HepG2 cells and for the ectopically expressed human NaCT in HEK293 cells. The IC50 is ~100 nM, representing the highest potency among the NaCT inhibitors known to date.

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。
