EHT 1864是Rac1信号转导抑制剂,能调节γ-分泌酶介导的APP。
EHT 1864 is a small molecule inhibitor of Rac1 signaling; modulate γ-Secretase-mediated APP processing. Inhibitor of Rac family GTPases. Mechanistic studies have shown that this molecule selectively inhibits Rac1 downstream signaling via guanine nucleotide displacement. Blocks activation by direct binding to Rac1, Rac1b, Rac2 and Rac3 (KD values are 40, 50, 60 and 250 nM respectively). Inhibits Rac, Ras and Tiam-induced growth transformation of NIH-3T3 fibroblasts. Reduces β-amyloid peptide production in vivo. More specifically, EHT 1864 has been found to affect Rac1-dependent, platelet-derived, growth factor-induced lamellipodia formation.

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,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。
