生物活性
TAK-242 (Resatorvid) is a small-molecule-specific inhibitor of Toll-like receptor (TLR) 4 signaling. TAK-242 inhibits the production of lipopolysaccharide-induced inflammatory mediators by binding to the intracellular domain of TLR4. TAK-242 also inhibited mRNA expression of IL-6 and TNF-alpha induced by LPS and interferon-gamma in RAW264.7 cells. TAK-242 suppressed the production of these cytokines from LPS-stimulated human peripheral blood mononuclear cells (PBMCs) at IC50 values from 11 to 33 nM. Intravenous administration of TAK-242 to mice 1 h before LPS challenge dose-dependently inhibited LPS-induced increases in serum levels of TNF-alpha, IL-1beta, IL-6, IL-10, MIP-2, and NO metabolites. TAK-242 protected mice from LPS-induced lethality in a similar dose-dependent manner, and rescued 100% of mice at a dose of 1 mg/kg.

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 |

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。
