生物活性

ML417 is a highly selective and brain penetrant D3 dopamine receptor (D3R) agonist, with EC50 of 38 nM. ML417 potently promotes D3R-mediated β-arrestin translocation, G protein activation, and ERK1/2 phosphorylation (pERK) while lacking activity at other dopamine receptors. ML417 interacts with the D3R in a unique manner, possibly explaining its remarkable selectivity. ML417 was also found to protect against neurodegeneration of dopaminergic neurons derived from iPSCs.

In vivo pharmacokinetics experiments in mice (using 20 mg/kg; i.p.) reveals that ML417 is brain penetrant and exhibits a plasma half-life of 3.44 hours and a brain half-life of 4.23 hours. ML417 displays a plasma Tmax of 0.5 hours and Cmax of 6500 ng/ml, and a brain Tmax of 0.25 hours and Cmax of 28000 ng/ml.

化学数据

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）

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K_m系数（3），再除以大鼠的K_m系数（6），得到化合物用于大鼠的等效剂量为10 mg/kg。
