生物活性
T3MG is a selective inhibitor of excitatory amino acid transporters GLT-1, EAAT2, and EAAT4. T3MG has long been utilized as a gold standard in the study of general EAAT function. It has more recently been shown to be selective for EAAT2 and EAAT4 as compared to EAAT1 and EAAT3 in electrophysiology and glutamate/aspartate uptake assays. Although there are other EAAT2-selective compounds, this is the first tool with selectivity for EAAT4. T3MG is not a substrate for the transporters themselves, nor does it have activity at glutamate ion channels.

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。
