生物活性
PF-06882961 is a potent, orally bioavailable agonist of the glucagon-like peptide-1 receptor (GLP-1R) agonist. PF-06882961 stimulates cAMP accumulation in CHO cells expressing both the human and monkey GLP-1Rs with comparable EC50 values. PF-06882961 shows mild to moderate damage to the heart, moderate to severe effects on the thymus gland (which helps with managing infection), mild to moderate stomach ulcers at the highest dose level given in the rat.

| 方法 | HEK293 cells stably expressing hGLP-1R fused to green fluorescent protein (GFP) (400,000 cells per well) are cultured onto 6 well plates for 24 hours and stimulated with PF-06882961 for 30 minutes. An agonist concentration of 1 μM shown to induce maximal internalization is chosen for these studies. In selected wells, cells are washed three times with PBS containing 0.1 % BSA and incubated at 37 °C for an additional 2 hours to assess reversibility of the endocytosis process. Cells are then fixed with 4% paraformaldehyde for 15 minutes at room temperature followed by three washes with PBS containing 0.1% BSA. |

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）
| 小鼠 | 大鼠 | 兔 | 豚鼠 | 仓鼠 | 狗 |
| 重量 (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
| 体表面积 (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
| Km系数 | 3 | 6 | 12 | 8 | 5 | 20 |
| 动物 A (mg/kg) = 动物 B (mg/kg) × | 动物 B的Km系数 |
| 动物 A的Km系数 |
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。
