GW6471 completely inhibits GW409544-induced activation of PPARα with IC50 of 0.24 μM. GW6471 at concentration ranging from 0.001-10 μM disrupts the interactions between PPAR and coactivator motifs derived from SRC-1 or CBP, but promotes the binding of the co-repressor motifs from SMRT or N-CoR. GW6471 adopts a U-shaped configuration and wraps around C276 of helix 3, destroys the integrity of the charge clamp but leaves sufficient space to accommodate the additional helical turn of the co-repressor motif in the PPAR/GW6471/SMRT complexes. GW6471 at concentration of 10 μM significantly prevents cardiomyocyte differentiation and results in the reduced expression of cardiac sarcomeric proteins (ie α-actinin, troponin-T) and specific genes (ie α-MHC, MLC2v) in a time-dependent manner through inhibiting PPARα.

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，已知某工具药用于小鼠的剂量为88 mg/kg , 则用于大鼠的剂量换算方法：将88 mg/kg 乘以小鼠的Km系数（3），再除以大鼠的Km系数（6），得到该药物用于大鼠的等效剂量44 mg/kg。
