生物活性
S-17092 is a potent, selective inhibitor of Prolyl oligopeptidase (POP), also known as prolyl endopeptidase (PEP or PE). Ki=1.5 nM. Nootropic.
S-17092 inhibition of POP prevents breakdown and thus increases the activity of a number of neuropeptides, which is likely the basis for its nootropic activity. S 17092 has been shown to improve cognition. It improved cognitive task performance in chronic low dose MPTP-treated monkeys. S-17092 was recently used to inhibit the formation of AcSDKP from its precursor 43-mer thymosin ?4 (T?4). Ac-SDKP is involved in hemopoietic stem cell differentiation, is pro-angiogenic and antifibrogenic.

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。
