生物活性
MIND4-17 is a potent NRF2 (nuclear factor erythroid 2-related factor 2) activator that covalently modifies a critical stress-sensor cysteine (C151) in the BTB domain of the E3 ligase substrate adaptor protein Kelch-like ECH-associated protein 1 (KEAP1), the primary negative regulator of NRF2. MIND4-17 induces NRF2 activation responses in neuronal and non-neuronal cultures (effective conc. 0.1-10 μM) of human, mouse, and rat origins. In addition, MIND4-17 effectively reduces endotoxin-induced IL-6 release from WT as well as YAC128 HD mutant mice-derived primary microglia and astrocytes, however, NRF2 induction by MIND4-17 is shown to be compromised in human Huntington′s diseased (HD) relative to non-disesed neural stem cells due to suppressive influence of the expanded CAG repeat mutation on pathway activation.

| 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。
