生物活性

NSC-23766 blocks the activation of Rac 1 through binding the GEFs including Trio and Tiam 1. In human dermal microvascular endothelial cells, NSC-23766 decreased trans-endothelial electrical resistance and caused the intercellular gap formation. Inhibition of Rac 1 by NSC-23766 shortly reduced endothelial barrier functions as revealed by measurement of TER and the appearance of intracellular gaps [2]. In the mucous cell of the intestine, inhibition of Rac1 either by NSC-23766 protected cells from TNF-α-induced apoptosis by inhibiting caspase-3, -8 and -9 activities. Inhibition of Rac1 significantly prevented TNF-α-induced activation of JNK1/2, but did not modulate TNF-α-induced ERK1/2, Akt and p38 MAPK activity.

动物实验
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）

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。
