产品介绍

生物活性

Hydralazine hydrochloride is a hydrochloride salt of hydralazine (Apresoline) that is a direct-acting smooth muscle relaxant with an IC50 of 1.9 mM. Hydralazine (Apresoline) is used to treat high blood pressure. Hydralazine hydrochloride works by relaxing the blood vessels so that blood can flow more easily through the body. Hydralazine hydrochloride increases guanosine monophosphate levels, decreasing the action of the second messenger IP3, limiting calcium release from the sarcoplasmic reticulum of smooth muscle. This results in vessel relaxation. Hydralazine hydrochloride dilates arterioles more than veins. Hydralazine hydrochloride recently has been identified as a nitric oxide donor. Activation of hypoxia-inducible factors has been suggested as a mechanism. Hydralazine hydrochloride relaxes vascular smooth muscles of arteries and arterioles, causing peripheral vasodilation and decreasing peripheral vascular resistance. These actions decrease blood pressure and increase heart rate, stroke volume, and cardiac output.

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)

小鼠大鼠豚鼠仓鼠
重量 (kg)0.020.151.80.40.0810
体表面积 (m2)0.0070.0250.150.050.020.5
Km系数36128520
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。
